PUMPS

Pumps

Is a device used to move fluids, such as liquids or slurries. A pump displaces a volume by physical or mechanical action.

3. Rotary pumps

CLASSIFICATION OF PUMPS

Reciprocating Pumps

A pump having a plunger that move back and forth within a cylinder equipped with check valves.

a. Piston pump
b. Plunger Pump
c. Diaphragm pump

Types of Reciprocating Pumps

Piston pump

Water is sucked into a sealed vacuum by use of a piston.

Plunger Pump

A reciprocating pump where the packing is on the stationary casing instead of the moving piston.

Diaphragm pump

A pump that uses diaphragm to isolate the operating parts.

Centrifugal Pumps

It contains an impeller, mounted on a rotating shaft.

• Single suction pump

• Double suction pump

Types of Centrifugal Pump:

Rotary pumps

A displacement pump that delivers a steady flow by the action of two members in rotational contact.

a. Turbine pump
b. Booster pump
c. Fire pumps

Types of Rotary pump:

Turbine pump

It has a vertical turbine located below ground water levels and a driving motor located at ground.

Booster pump

A pump used to increase the pressure in a water supply line.

Fire pumps

It is designed for connection to automatic sprinkler systems.
