Pump Types And Characteristics

Pump Types / Characteristics – Tanker Basics. There are many types of pumps, each with its own characteristics, advantages and disadvantages. Basically, pumps can be broadly categorised into 3 types : Non-positive-displacement pumps e.g. centrifugal pumps. Positive displacement pumps e.g. reciprocating pumps, gear pumps, screw pumps, etc.

    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. Positive Displacement pumps generally makes more pressure than Centrifugal Pumps.

    Sep 20, 2019 · Figure 1. Centrifugal Pump Characteristics. Creating a resistance to the flow controls the kinetic energy of a liquid coming out of an impeller. The first resistance is created by the pump volute (casing), which catches the liquid and slows it down. When the liquid slows down in the pump casing, some of the kinetic energy is converted to pressure energy.
