1) Rotary type such as..twin and multi screw, progressive cavity, gear , lope
2) Reciprocating..plunger , piston
Most rotary PD pumps do not need pulsation dampener because of the very low or almost zero pulsation flow.
Please Google for the various pump type to understand their pumping action and see for your self why a pulsation dampener is needed in a system with reciprocating PD pumps.
