Wilden P400 Pro-Flo Series | Bolted Plastic AODD

Wilden 38 mm (1-1/2") Pro-Flo® Series Bolted Plastic AODD Pump - P400

Description
The Wilden 38 mm (1-1/2") Pro-Flo® Series Bolted Plastic AODD Pump (P400) is engineered for maximum performance and efficiency, offering superior containment for chemical and industrial applications. Part of the Wilden Pro-Flo® Series, this Air-Operated Double-Diaphragm (AODD) pump features a bolted construction and a redesigned liquid path that reduces internal friction, ensuring higher flow rates and longer diaphragm life. Its plastic construction provides excellent corrosion resistance, making the P400 ideal for industries requiring reliable fluid transfer with large solids handling.
