The AH Series
High Pressure Diaphragm Pump
ALMATEC's high-pressure diaphragm pumps have been specially developed for charging filter presses with chemical wastes and special sludge.
With a driving pressure of max. 7 bar, the pumps of series AH are able to produce a delivery pressure of 16 bar on account of the internal pressure boost. These genuine double-action pneumatic diaphragm pumps are available in three sizes with a maximum delivery volume of 20 m³/h.
All housing parts in contact with the product are made of PE UHMW. This polymer material is seven times more resistant to abrasion than PP. PE is also more resistant to wear than cast iron, aluminium and even steel.
AH Series series pumps are available with FDA Approvals
