1.1 Purpose and types of pumping stations

The main purpose of pumping stations is to transfer fluids from

low points to higher points.The main types of pumping stations are:

Wastewater PS.

Water PS. Sludge PS.

Storm water PS.

1.2 Types of pumps

Pumps are classified into two main categories:

Kinetic pumps.o Centrifugal pumps ( radial, axial, mixed flow)

o Turbine (vertical) pumps

Positive displacement pumps.

o Rotary pumps ( screw, lobe)

o Reciprocating pumps (plunger)

Kinetic Pumps: Centrifugal Pump

The common feature of all centrifugal pumps is the Volute

Rotary Pump: Screw pumping station

In the screw pump a revolving shaft fitted with blades rotates in an inclinedtrough and pushes the water up the trough.

Reciprocating Pump: Screw pumping station

• In the reciprocating pump a piston sucks the fluid into a cylinder then pushes it

up causing the water to rise.
