What is end suction centrifugal pump?

An End Suction Pump is a type of Centrifugal Pump where the suction is axial and the discharge is at 90 degrees to the suction. Many designs have a centre line discharge to comply with worldwide or regional standards.

What is an end suction water pump?

An end suction pump is a centrifugal pump that has a casing with suction going out one end and discharge coming out the other. These pumps are usually a single stage with only one impeller.

Where are end suction pumps used?

Once fitted with open impellers for potential solids handling, end suction pumps can also be used in chemical or food processing applications. A closed impeller option would be used for relatively clean water and oil services. The pump shaft can be sealed from the environment in a variety of ways.

What is the difference between split case and end suction pumps?

Pump suction and discharge are arranged in the horizontal direction and are perpendicular to the shaft. Split-case pumps can be either single-suction or double-suction. In a single-suction pump, the water enters the impeller from only one side. For double-suction, the fluid enters the impeller from both sides.

What is close coupled end suction pump?

Close–coupled pumps are characterized by a common motor and pump shaft or by their motor shaft and pump shaft being rigidly connected in a pump casing. The pump casing is bolted to the drive flange rather than being installed on pump feet.

What is principle of centrifugal pump?

The basic principle of operation of centrifugal pumps is – force vortex flow. This means, when a body of liquid is acted upon by an external torque, it increases the pressure head of the rotating liquid. This increase in pressure is directly proportional to the velocity of the liquid.

What is double suction pump?

Double-suction pumps are employed when the flow rate required of a centrifugal pump becomes too large for the inlet cross-sections of one impeller or when the flow velocity in the inlet cross-section of the first impeller has to be reduced to prevent cavitation.

What is the difference between a close coupled and a long coupled pump?

Long coupled refers to a Bareshaft BPO pump and electric motor mounted independently on a base and connected via a spacer coupling. Close Coupled refers to the design of an intermediate yoke which allows the pump to have a direct connection to a standard metric frame flanged electric motor.

How does centrifugal pump create suction?

Centrifugal pumps move fluid by using centrifugal force to generate velocity of the liquid. Fluid enters the pump through the suction nozzle, into the eye of the impeller. The impeller vanes catch the fluid and rotate it, both tangentially and radially until it exits the pump on the discharge side.
