Types of pumps used for sludge Plunger, Double Disc, & Diaphragm Progressing Cavity Pumping sludge Rotary Lobe Centrifugal
Positive displacement pumps are.. • Those in which energy is imparted to the liquid in a fixed displacement volume. • Such as a casing or a cylinder, by the rotary motion of gears, screws or vanes, or by reciprocating pistons or plungers. Dynamic pumps are… Dynamic pumps impart energy to the liquid by means of an impeller or propeller. This force is converted to pressure as the fluid is pushed against the pump casing.
