What is a bb4 pump?

The BB-4® is a high-pressure centrifugal pump that has been used by forestry agencies to combat wildfires for over 40 years. It has been the weapon of choice in many wildland operations and is especially suited for type 6 brush trucks.

What is vertical pump?

A vertical turbine pump is a specialized type of centrifugal pump that is designed to transport fluid from a reservoir that is often deep underground.

What is an API 610 pump?

API 610 is the API standard relating specifically to centrifugal pumps and centrifugal pumping systems. It provides design criteria for the design of the actual centrifugal pump, as well as how the centrifugal pump is to be tested, and what type of base it is to be mounted on.

Which pump is used for high pressure?

Multi-stage centrifugal pumps tend to be used for applications that require higher pressure or pressure head. Diaphragm type pumps are generally deployed within the following ranges: Flow rate ranges between 20 to 750,000 lpm.

What are the 2 main classification of pumps?

Pumps are divided into 2 major categories: Dynamic and Positive Displacement (aka Displacement).

What are the 2 types of gear pump?

There are two basic types: external and internal. An external gear pump consists of two identical, interlocking gears supported by separate shafts. An internal gear pump has two interlocking gears of different sizes with one rotating inside the other.

What is API in pump?

A type of pump designed to meet the American Petroleum Institute (API) 610 standard for pumps handling hydrocarbons. They come in many different forms and may employ a number of pumping mechanisms. The API 610 standard is limited to centrifugal pumps, but API process pumps come in many different configurations.

What is centerline mounted pump?

Most ANSI pumps are designed with foot mounted casings. … Centerline support simply means that the pump casing is supported at the shaft centerline. This allows thermal expansion growth of the casing to be symmetric from the shaft centerline outwards.

What is OH3 pump?

The pump type ETLS (OH3) vertically inline mounted, flexible coupled, radial split case, single stage, single suction, heavy duty centrifugal process pumps. … The inline configuration is a compact pumping solution that eliminates the need for an expensive baseplate saving valuable floor space.

What is BB5 pump?

The BB5 type, KBDS and KBDD pumps are double casing, radially split multistage between bearing pumps conforming to API 610 requirements. These pumps are suitable for wide applications in high pressure fluid handling in oil refineries and petrochemical industry.

What is water pump suction?

Suction pressure is how much water your pump can suck in through its inlet. Many pumps specify a suction lift, represented in metres. This represents how far down your water pump can lift water up from into itself.

What is VS type pump?

VS1 type pump is a single casing vertically suspended type design. It is used as a wet pit or diffuser pump. The column of a pump is used as a discharge from the pump.

Which pump is more efficient?

Where different pump designs could be used, the centrifugal pump is generally the most economical followed by rotary and reciprocating pumps. Although, positive displacement pumps are generally more efficient than centrifugal pumps, the benefit of higher efficiency tends to be offset by increased maintenance costs.

What is BB3 pump?

General. Our API 610 type BB3 pumps are multistage, centre line mounted, axial split, single suction, between bearing pumps. The pump and motor are flexibly coupled and installed on a common baseplate.

What are vertical pumps used for?

As water pumps, vertical pumps are used for deep well pumping and move water from its underground source to buildings for human use or to prevent flooding or drainage issues.

Why do we use vertical pumps?

When you have a restricted surface area and need a pump that takes up a much smaller footprint, vertical centrifugal pumps will definitely take up less floor space. They are well-suited for liquids with high temperatures and pressures, and the NPSH can be altered to handle a wider range of applications.

How many types of vertical pumps are there?

The two main types of turbine pumps are vertical turbine pumps and submersible turbine pumps.

What is pump Slideshare?

Pump A pump is a device used to move fluids, such as liquids, gases or slurries. It increases the mechanical energy of the fluid. The additional energy can be used to increase –  Velocity (flow rate)  Pressure  Elevation.

What is cavitation in pump?

Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. It occurs because there is not enough pressure at the suction end of the pump, or insufficient Net Positive Suction Head available (NPSHa). When cavitation takes place, air bubbles are created at low pressure.

What do you mean by impeller?

An impeller is a part of a pump or compressor that rotates at a high speed and acts as a propeller to increase a fluid’s pressure and flow rate. Impellers are made from various metals such as steel, iron or bronze, as well as plastics.

Which pump is used in homes?

Pedestal Sump PumpsSubmersible Sump PumpsPool PumpsPedestal pumps are positioned with the pump motor out of the water and above the sump basin.Submersible sump pumps are put underwater in your sump pump basin.Water pumps send water through the filter, heater and chlorinator.

What is priming in pump?

What is pump priming? Priming simply means preparing or getting something ready for operation. For a centrifugal pump to work properly, you need to fill it up with water. … The pump will resume operation once the air is removed.

What is rotary gear pump?

An internal rotary gear pump is a positive displacement pump which employs a rotor and idler gear assembly to generate its flow. … As the rotor gear drives the idler gear, the space caused by the crescent offsetting the gears and the meshing of the gear teeth displace the fluid, expelling it to the discharge port.

What is Rotary Lobe pump?

Rotary lobe pumps are positive-displacement type pumps that use two or more lobes rotating around parallel shafts in the pump’s body to move liquids. They are widely used in the hygienic processing industries, including food & beverage processing and biopharmaceutical manufacturing.

What is the difference between ANSI and API?

In general, ANSI pumps provide reliable service across a range of applications and are the pump of choice for chemical processing. … API pumps are heavier duty and should be considered for higher pressure and temperature applications. They are the pump of choice for aggressive oil refinery processes.

What does a center line do?

2.2 Center lines. Center lines denote a circular feature such as a shaft or a hole. A rectangular feature seen on an elevation of a drawing could be identified either as a circular feature or a rectangular feature. The center line is the method of quickly identifying the shape.
