The main difference is in design of the impellers, which give high discharges at low heads. Types of Pumps Centrifugal Water Pump. Pump is a machine or mechanical equipment which is required to lift liquid from low level to high level or to flow liquid from low pressure area to high pressure area or as a booster in a piping network system. This pump operates the same way as the piston pump except that, in place of a piston that moves in a cylinder, a flexible diaphragm moves back and forth in a closed area. Delivery Pipe. ITT Goulds Pumps and Rheinhütte Pumpen makes the widest range of pumps in the industry — pumps to handle virtually any service. Centrifugal pumps are designed with a rotating impeller which can be used for supplying the water into the pump and force the discharge flow. Centrifugal pumps Centrifugal Pumps •Develop pressure by increasing the velocity of the liquid •Liquid is literally flung out of the cutwater . Suction Valve. These mechanical devices use centrifugal force — the fictitious or apparent force that points opposite of the force that keeps an object on its circular path. • As the name suggests, it relies on the principal of Centrifugal force. Positive Displacement Pumps •Allow liquid to flow into an open cavity •Trap the liquid in the pump •Transport liquid from the Pumps of this type are called double volute pumps (they may also be referred to a split volute pumps). The two types of pumps behave very differently regarding pressure head and flow rate: • The Centrifugal Pump has varying flow depending on the system pressure or head • The Positive Displacement Pump has more or less a constant flow regardless of the system pressure or head. Centrifugal pumps can also be constructed in a manner that results in two distinct volutes, each receiving the liquid that is discharged from a 180. o. region of the impeller at any given time. Pump also can be used in process operations that requires a … These are the main parts of a Reciprocating Pump: Suction Pipe.
