AODD Pumps handle viscous, solid-laden slurries.

Press Release Summary:




Available with simplex technology to generate 250 psig with pressure ratio of 2:1, H400 Series 1 ½ in. Air-Operated Double Diaphragm Pumps do not require external boosters or amplifiers to achieve required pressure output. During operation, only one liquid chamber is used to pump fluid while other is used as pressure-amplification chamber. This allows pumps to have flow rate of 64 gpm with max suction lift of 10.1 ft and ability to pass solids as large as 5/16 in.

Wilden® H400 High Pressure AODD Pumps Handle Viscous, Solid-Laden Slurries



Grand Terrace, CA - Wilden®, the worldwide leader in air-operated double-diaphragm pump technology, announced today that its H400 High Pressure Air-Operated Double-Diaphragm (AODD) Pumps have been designed to reliably transfer viscous, solid-laden slurries at high head pressures.

These 38mm (1-1/2") pumps are available with simplex technology to generate upwards of 17.2 bar (250 psig). The simplex creates a 2:1 pressure ratio, meaning that these pumps do not require costly external boosters or amplifiers to achieve the required pressure output. Also during operation, only one liquid chamber is used to pump fluid while the other is used as a pressure-amplification chamber. This allows the pump to have a flow rate of 242 lpm (64 gpm) with a maximum suction lift of 3.1m (10.1 feet) and the ability to pass solids as large as 8.0mm (5/16").

The H400 pumps also feature Wilden's patent-pending Pro-Flo V Air Distribution System (ADS). This ADS greatly improves the performance characteristics of AODD pumps through the incorporation of three moving parts: the unbalanced air valve spool, the pilot spool and the main shaft/diaphragm assembly. This design results in optimized air flow in the pump.

Jim Wilden, founder of Wilden Pump and Engineering Co., revolutionized the pumping industry when he invented the air-operated double-diaphragm pump in 1955. Since then, Wilden has created a line of distinctive pumps that have proven to be trustworthy solutions to pumping applications in a wide variety of industries. Wilden-headquartered in Grand Terrace, California, USA-is a member of Dover Corporation's Pump Solutions Group (PSG).
