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.
