A positive displacement pump includes a drive unit and a pump unit. The pump unit comprises a plurality of working chambers, a plurality of displacement elements, and at least three cylinders. The pump unit is configured to be double-acting.ALFRED GIESSBACH...
The volume is a constant given each cycle of operation. The positive displacement pumps can be divided in two main classes reciprocating rotary The positive displacement principle applies whether the pump is a rotary lobe pump progressing cavity pump rotary gear pump piston pump diaphragm pump screw...
Positive displacement pumps can be divided into two categories in terms of their operation: (i) reciprocating; or (ii) rotary pumps. Reciprocating pumps use a crankshaft to transfer the rotational drive power to a plunger, piston or diaphragm oscillating within a cylinder, whereas rotary pumps ...
