6. PUMPS AND PUMPING SYSTEM

The pressure (head) that a pump will develop is in direct relationship to the impeller diameter, the number of impellers, the size of impeller eye, and shaft speed. Capacity is determined by the exit width of the impeller. The head and capacity are the main factors, which affect the horsepower size of the motor to be used.

What is the difference between pressure and head?

May 31, 2016· The pump selection of a pump is driven by the following main parameters: Head (H) Flow rate (Q) Fluid characteristics (ρ, γ, T .) Sometimes head can be confused with pressure during pump choice. As a matter of fact there is a strict relation between them which is defined by the fluid specific gravity, so the relation is fluid dependent.

Positive Displacement Pumps an overview ScienceDirect

Pratima Bajpai, in Biermann's Handbook of Pulp and Paper (Third Edition), 2018. Metering Pumps. Positive displacement pumps are often used as metering pumps because they accurately control flow rates by changing the speed at which the pump is driven without regard to the back pressure. They are also used to pump relatively small volumes of liquids against high pressures.
