Almatec AHS

Plastic Air Operated Double-Diaphragm Pumps for High-Pressure Applications

Almatec AHS Series have been specially designed for the safe operation of high-pressure applications up to 15 bar (218 psig). AHS Series pumps are available in two sizes (AHS 15 and 25) and a typical application of these pumps includes filter press feeding.

AHS Series pumps do not have an internal booster. Due to the 1:1 ratio of drive/discharge pressure the corresponding air pressure must be supplied externally, e.g. from the compressor itself or an external pressure booster.

The solid design of the AHS and ring tightening structure give maximum pump safety. Corrosion proof and wear resistant housing allows the pump to comfortably operate in hazardous environments. No drives, rotating parts or shaft seals minimise maintenance and operation costs. AHS includes specially developed heavy-duty diaphragms for longer service life. Dry running, self-priming and easy start up capabilities
