Couplings Type

Couplings for pumps usually fall in the category of general-purpose couplings. General purpose couplings are standardized and are less sophisticated in design. The cost of such coupling is also on the lower side. In addition, there are special purpose couplings that can be used on turbo machines and are covered by the API 671 specification.

In these couplings, the flexible element can be easily inspected and replaced. The
alignment demands are not very stringent. The couplings fitted on pumps usually fall inany of the five types mentioned below.
These are:
1. Gear coupling
2. Grid coupling
3. Disk coupling
4. Elastomeric compression type
5. Elastomeric shear type.

Seismic Survey

The most accurate and widely used means of finding good drilling locations is the seismic survey. Seismic surveying involves sending sound waves down into the ground and recording the echoes that bounce back off the various sedimentary layers.The sound or shock waves are generated by; setting off small explosive charges just below the surface; hitting the ground with a heavy weight; or shaking the ground using large vibrator trucks. The echoes returning from the subsurface are detected by sensitive instruments called geophones which are strung out along the ground in a straight line. The geophones are connected by electrical cable to a recording system. The recording system precisely records, to the nearest one thousandth of a second on magnetic tape, the time it takes for the echoes to return to the surface. By knowing the amount of time it takes for a sound wave to reach a certain layer and then bounce back to the surface, as well as the speed of sound through the rock
layers in between, the geophysicist is able to determine the depth to that layer at that location. By determining the depth at a large number of points along the seismic line, the geophysicist is able to create a profile of the underground layers along the line.

Pump System Life Cycle Cost Reduction

The primary objective of life cycle costing is to evaluate and/or optimize product life cost while satisfying specified performance, safety, reliability, accessibility
maintainability, and other requirements. Pumping systems account for an estimated 25%-50% of the energy usage in many industrial plants, and perhaps 20% of the world’s electric energy demand. Centrifugal pumps rank first in failure incidents
and maintenance costs. That is why centrifugal pumps in critical applications are installed in identical pairs, one serving as the operating, the other one serving as the standby or spare pump. Despite these statistics, many pump purchase decisions
are still made solely on the basis of lowest initial purchase and installation cost. The notion exists that, if a cheap pump doesn’t perform well, it can always be
upgraded. While this may be true in those pumps that suffer from installation errors or component defects, it is not true for pumps that suffer from fundamental design
compromises. Moreover, these decisions seem to disregard that initial purchase price is generally only a small part of pump life cycle cost in high usage applications.
Market conditions, short-term financial considerations, and organizational barriers are to blame for this shortsighted approach.

LCC = Cic + Cin + Ce + Co + Cm + Cdt + Cenv + Cd
where:
LCC = Life Cycle Cost
Cic = Initial Cost, purchase price (pump, system,
pipe, auxiliary services)
Cin = Installation and commissioning cost
Ce = Energy costs (pump, driver & auxiliary services)
Co = Operation costs
Cm = Maintenance and repair costs
Cdt = Down time costs
Cenv = Environmental costs
Cd = Decommissioning and/or disposal costs

Wellhead

The wellhead is equipment used to maintaain surface control of the well. It is usually made of cast or forged steel and machined to a close fit to form a seal and prevent well fluids from blowing or leaking at the surface.

Flange Standards

There are a variety of standards used in the design and selection of flanges. The
following codes and standards relate to pipe flanges:
ASME Codes and Standards:
B16.1 Cast Iron Flanges and Flanged Fittings
B16.5 Pipe Flanges and Flanged Fittings
B16.24 Bronze Flanges and Fittings–150 and 300 Classes
B16.42 Ductile Iron Pipe Flanges and Flanged Fittings–150 and 300 Classes
B16.47 Large Diameter Steel Flanges

Shaft couplings

A shaft coupling transfers torque between two in-line, or nearly in-line, rotating shafts. The magnitude of the torque in the shafts is equal, although slipping and disengagement can cause speed variations. In its simplest, and perhaps oldest form, the coupling acts as a means of joining shafts. Another function is to join two shafts which are not necessarily in perfect alignment with each other. The coupling in this case must be capable of absorbing such misalignment. Modern couplings,
between pump and driver, must be capable of rapid disassembly.

Baseplates

Pump units are mounted on baseplates to allow the unit to be bolted down. Unless otherwise stated, baseplates are designed for mounting on concrete foundations and to be supported over the whole length by grouting. The pump supplier must be aware if a baseplate is intended for mounting on structural steelwork with intermittent supports. The design of the baseplate side members may need adjusting to preserve alignment. If the baseplate is to be grouted in with epoxy grout rather than concrete, a special paint finish will be required on the contact surfaces. If the baseplate is to be welded down to structural steelwork the pump supplier should be informed.

Pump efficiency

The pump does not completely convert kinetic energy to pressure energy since some of the kinetic energy is lost in this process. Primarily, there are three areas where this energy is dissipated and not converted to useful work. Pump efficiency is a factor that accounts for these losses. Pump efficiency is a product of the following three efficiencies:

1. Hydraulic efficiency
(primarily, disk friction, which is the friction of the liquid with the impeller shrouds. This is a function of speed and impeller geometry. Other losses are shock losses during rapid changes in direction along the impeller and volute)

2. Volumetric efficiency
(recirculation losses at wear rings, interstage bushes and other)

3. Mechanical efficiency
friction at seals or gland packing and bearings). Some texts call the product of the first two efficiencies as internal efficiency of the pump. Every pump is designed for a specific flow and a corresponding differential head, though it is possible to operate at certain percentage points away from the designed values. However, the efficiency of the pump at the designed point is maximum and is called as the BEP. Efficiency at flows lower or higher than this design point is lower. The efficiency of the pump has a close relationship to an important pump number called as the specific speed.

Pump Priming System

FOOT VALVES
A foot valve is a form of check valve installed at the bottom, or foot, of a suction line.When the pump stops and the ports of the foot valve close, the liquid cannot drain back to the suction well if the valve seats tightly. Foot valves were very commonly used in early installations of centrifugal pumps. Except for certain applications, their use is now much less common.

PRIMING CHAMBERS
Chamber primer is a tank with a bottom outlet thatis level with the pump suction nozzle and directly connected to it. An inlet at the top of the tank connects with the suction line. The size of the tank must be such that the volume contained between the top of the outlet and the bottom of the inlet is approximately three times the volume of the suction pipe. When the pump is shut down, the liquid in the suction line may leak out, but the liquid in the tank below the suction inlet cannot run back to the supply. When the pump is started, it will pump this entrapped liquid out of the priming chamber, creating a vacuum in the tank. The atmospheric pressure on the supply will force the liquid up the suction line into the priming chamber.

PRIMING INDUCTORS
If a separate source of liquid of sufficient capacity and pressure is available, it can be used to fill the suction line of the pump to be primed through the use of an inductor. For water, the pressure must be equal to about 4 lb/in2 for each foot (90 kPafor each meter) of head necessary to prime the pump, measured from the lowest liquid level in the sump from which priming must be accomplished to the top of the pump. The amount of liquid necessary depends on the pressure.

CENTRAL PRIMING SYSTEMS
If there is more than one centrifugal pump to be primed in an installation, one priming device can be made to serve all the pumps. Such an arrangement is called a central priming system. If the priming device and the venting of the pumps are automatically controlled, the system is called a central automatic priming system.

Slurry Pump

Mine Dewatering Pump

What should we consider to select or design "Mine Dewatering Pump" ?
- Liquid properties (solid content, solid size, abrasive?, corosive?)
- Make sure about suction condition (negative? we'll need priming system)
- Pump driver (we'll need independent power source; diesel engine; generator set)
- pump skid (skate board, ponton, etc)

Killing Well Pump

- High pressure triplex plunger pump can be use for killing well pump
- Flow rate can be control by adjust pump speed or bypass the pump flow

Allweiler® pumps from Colfax help keep Hermann Bantleon operations running smoothly

Challenge:
Germany’s Hermann Bantleon GmbH,one of the world’s leading producers and suppliers of lubricants, relies on a combination of speed, flexibility and superior customer
service to deliver both universal and customized product lines to its customers
around the globe. That means operating a wide array of pump types and sizes to
maximize the efficiency of the company’s manufacturing processes.

Solution:
For nearly 30 years, Bantleon has relied on Allweiler AG of Radolfzell, Germany,
for all of its pumping demands. Over those years Allweiler has successfully supplied
different pump types, regardless of the specific pumping task. Sometimes capacity
is a critical factor in selecting a pump for a specific application; other times it’s the type of liquid to be pumped.

Results:
Today Bantleon is able to obtain all of the pumps that it needs from a single source
and with just one contact for sales and service. In total about 80 Allweiler® pumps
are installed at the company’s Ulm location. Seventy of those are screw pumps for
lubricating liquids. Approximately 10 pumps used to move easily combustible
liquids like solvents are installed in explosion-proof versions.

Working To Meet Customer Demands
The development, production and sale of lubricants is a major business segment at Hermann Bantleon GmbH. At its plant in Ulm,Germany, Bantleon begins with high-quality base oils and produces both universal and customized lubricants, according to its own formulas. Customized products are often the best way to meet special
customer requirements in both cutting and noncutting production processes. Bantleon also works to meet customer demands by improving its efficiency and quality-assurance systems. The company mixes additives to a variety of base oils, according to internally developed formulas. It then pulls retained samples from every batch and tests them in Bantleon’s own laboratory, before delivering products to customers.

Time-Tested Pumping Solutions
In addition to providing improved efficiency and superior product quality, Bantleon relies on fast reaction times and flexibility as vital elements of its customer-service capabilities. To deliver that speed and flexibility, the company counts on a wide range of pump types and sizes to play a major role in its manufacturing processes. Allweiler has been meeting those varied application demands for nearly three decades. In fact, nearly 40 SNH Series screw pumps have been in service in Bantleon’s base-oil tank farm over the past 30 years. And, incredibly, not one of the pumps has failed for an extended period of time or required repair during those three decades.

The Right Pump for the Right Job
Bantleon demands different pump types, depending on the specific pumping tasks required. Sometimes the lubricant’s capacity is the critical selection factor; sometimes it is the type of liquid that must be pumped. For example, moving nonlubricating or poorly lubricating liquids like antifreeze requires the use of side-channel pumps. Centrifugal pumps are ideal for clean lubricating liquids. Progressing cavity pumps and peristaltic pumps are better suited for contaminated
liquids, such as used oil. Peristaltic pumps are mostly used for moving used oil in systems at customer sites, because they can run dry, making them suitable for unsupervised operation. And small progressing cavity pumps work best for precisely metering and adding potentially expensive additives. Bantleon must be able to meet the requirements of each of these specific applications, either in its own roduction and filling plants or as part of its full line of services. Accordingly Allweiler AG offers these pump types, accompanied by a wide range of services, like recommending the right pump technology for the right application, as well as calculating and recommending expected NPSH requirements,friction losses and right pile diameter. This combination results in trouble-free and economical operation of the pump and allows Bantleon to obtain all of the pumps that it needs from a single
source, with just one contact for sales and service. Recently a new filling station required Bantleon to provide two AEB Series progressing cavity pumps, to precisely meter high-viscosity additives (up to 6,300 square millimeters per second [mm2/sec.] at 65 degrees Celsius liquid temperature), as well as four NT Series centrifugal pumps capable of moving 30 cubic meters (m3) of base oils at a temperature of 20 degrees Celsius. Depending on the liquid, pumps at Bantleon must be able to handle a viscosity range of between two and 10,000mm2/sec. In total about 80 Allweiler pumps
are installed at the company’s Ulm location. Seventy of those are screw pumps for lubricating liquids. Approximately 10 pumps used to move easily combustible liquids like solvents are installed in explosion-proof versions (ATEX). Nearly one million liters of lubricant are stored in the 80 tanks. Yearly pump throughput is proximately
15 million liters.

Building a Productive – and Profitable – Relationship
At Bantleon a long service life, low investment cost and high availability are major criteria for choosing a pump. But the long and excellent relationship between the two companies remains a key reason that Bantleon continues to purchase its new pumps from Allweiler. This holds true for pumps needed to expand its own production capabilities, as well as for plants that Bantleon constructs for its customers.
Compliance with environmental and worker-protection regulations is another important business consideration. So for Bantleon, it is not enough for the pump manufacturer to simply deliver high-quality pumps. Even more important, the pumps supplied must be able to take advantage of standardized procedures, allowing Bantleon to quickly and easily select the right pump for the job. Rainer Janz, responsible for product and quality management at Hermann Bantleon GmbH, says,“The pumps that we get from Allweiler exhibit consistently high quality; this gives us very high process stability and virtually no downtime.”These benefits go straight to the company’s bottom line, because backup pumps are unnecessary. Finally, Bantleon values superior
design. Allweiler pumps have excellent NPSH values (less than 3m),so that long piping and deep tanks ensure adequate reserves for pressure losses.According to Dieter Schrag, shop and production foreman of Hermann Bantleon GmbH, “Bantleon and Allweiler have had a very strong customer-supplier relationship for several decades. Our company started ordering Allweiler pumps back in the 1970s and 1980s. Obviously my colleagues made a good choice back then. We have found no reason to switch suppliers. We have always been satisfied with the pumpsand the support.”

Sulzer and Saudi Aramco Sign a Strategic Ten Year Supply Agreement

Sulzer announced today that it is the first company to negotiate and sign a Strategic Corporate Procurement Agreement (CPA) with Saudi Aramco, the world's largest oil producing company. The agreement was signed in the Kingdom of Saudi Arabia by Ton Büchner, CEO Sulzer and Kim Jackson, President Sulzer Pumps.



In a bid to simplify the procurement process, Saudi Aramco has embarked on an ambitious program of determining best business practices and commercial terms with all its key suppliers. The agreement with Sulzer is the first, and additional agreements with other companies are expected in the coming months.

The agreement covers the supply of products, system solutions, and services from all Sulzer divisions to Saudi Aramco for a 10-year period. Sulzer and Aramco have a long standing business relationship, and both companies feel that by moving to this higher level of cooperation greater efficiency gains may be achieved.

This is of particular importance as Saudi Aramco continues its high level of capital investment in both upstream and downstream projects in the oil and gas market.

Sulzer is looking forward to using the agreement as a future trading platform with Saudi Aramco and its partners.
