Do Reciprocating Pumps Cavitate?

Cavitation in Reciprocating Positive Displacement Pumps
Reciprocating positive displacement pumps do not typically suffer from internal, highly localized cavitation like high speed rotating pumps. However, they do have highly pulsed flow rate, which results in peak flow rates up to three times the average flow rate.

Is there cavitation in reciprocating pump?

Two basic types of cavitation exist in reciprocating pumps: Suction cavitation can result from obstructed, clogged, or otherwise dysfunctional inlet pipes. When the inlet pipe's optimal flow is hampered, vapor cavities form near the retracting plunger. ... Sub-optimal piping design.

What would cause a pump to Cavitate?

Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. It occurs because there is not enough pressure at the suction end of the pump, or insufficient Net Positive Suction Head available (NPSHa).
