Wilden 3" Pump Models

Wilden 3” Pump Operational Description

The Wilden 3” air diaphragm pump is a positive displacement pump that uses a combination of reciprocating action and either a flapper valve or a ball valve to transfer liquids. This pump is sometimes referred to as a membrane pump. Our Wilden air diaphragm pumps are self-priming and are ideal for viscous liquids. Our Wilden pumps use reciprocating elastomeric diaphragms and check valves to pump fluid. The liquid chambers are filled and emptied by fluid that is drawn through a common inlet and discharged through a single outlet. These pump models have 3” diaphragms for increased fluid movement. Wilden 3” pumps have excellent suction lift characteristics and can handle sludges or slurries with a relatively high amount of grit and solid content. Our Wilden air diaphragm pumps can also handle highly viscous liquids.
