Almatec AH Series Diaphragm Pumps
Almatec has announced the availability of its AH Series of high-pressure diaphragm pumps. These pumps have been developed for charging filter presses with chemical wastes and special sludges.

All AH Series pumps—which have no drives, rotating parts or shaft seals—have a driving pressure of maximum 7 bar with an internal pressure boost that can build a delivery pressure of up to 16 bar. The pumps are available in three sizes, based on their maximum delivery volume: AH 15 (18.5 gpm or 70 lpm), AH 25 (48 gpm or 180 lpm) and AH 40 (87 gpm or 330 lpm). Other built-in features are self-priming and dry-running capabilities; compact dimensions; easy start-up; a corrosion- and abrasion-proof housing; heavy-duty diaphragms; the maintenance-free PERSWING P air-control system; and flange connections to DIN or ANSI.
Almatec also offers the AH 20 STT-E model. While offering the same driving and delivery pressures of the other AH pumps, the AH 20 STT-E features wetted housing parts that are made of precision-cast stainless-steel 1.4408, with a center block (PE conductive), ball valves (PTFE) and diaphragms (PTFE/EPDM compound) constructed of plastic. This design gives the AH 20 STT-E a wide range of applications and allows it to meet the ATEX requirements of directive 94/9/EG.
