The Wilden air-operated diaphragm pump features a simple, robust design that makes operation and maintenance straightforward. Flow rate and pressure can be adjusted simply by regulating the compressed air supply pressure and volume. No complex electrical controls, variable frequency drives, or specialized training are required.

This translates to lower direct maintenance costs and reduced downtime for customers. Over 50 years of engineering refinement have made the Wilden pump increasingly reliable and service-friendly.
The pump can run dry indefinitely without damage, eliminating the risk of pump failure due to accidental loss of prime. It also features self-priming capability up to 7 meters, allowing it to be installed above the liquid level without additional priming equipment. The simple design also means fewer spare parts to stock, simplifying inventory management.
