Wilden releases HS430S AODD pump in aluminium

Wilden, part of PSG, a Dover company and a worldwide air-operated double-diaphragm (AODD) pump developer, has released an aluminium version of its HS430S Advanced FIT High Pressure 1-1/2” (38 mm) AODD pump.

Well-suited for applications that require high head pressures, such as viscous and solid-laden slurries, the HS430S high pressure aluminium pump comes equipped with the FIT wetted path.

This design feature minimises the number of fasteners and allows for single socket reassembly for faster, easier maintenance.

The new pump also provides high flow rates, is easy to maintain, and increases plant profitability, Wilden says.

The HS430S has been designed for high-grade containment, is a direct replacement for existing 1-1/2” (38 mm) high pressure aluminium pumps, and does not require any repiping during installation.

The pump features a Simplex design, which means that one liquid chamber is used to pump fluid while the other is used as a pressure amplification chamber.

With a 2:1 pressure ratio, the pump generates 17.2 bar and does not require costly external boosters or amplifiers to achieve this discharge pressure.

FIT high pressure aluminum pumps are fitted with the energy-efficient Pro-Flo Shift air distribution system (ADS).

This innovative ADS provides up to 60% reduction in air consumption compared to some other AODD pump technologies.
