AHD/AHS SERIES Air-Operated Double-Diaphragm Pumps Where Innovation Flows HIGH PRESSURE DIAPHRAGM PUMPS MADE OF PLASTIC AND STAINLESS STEEL AIR-OPERATED DOUBLE-DIAPHRAGM PUMPS CONSTRUCTED OF POYETHYLENE FOR HIGH-PRESSURE APPLICATIONS UP TO 15 BAR (218 PSIG)

Two Pump Series–One Result AHD internal Series Pump with pressure booster Pump without internal pressure booster The two sizes of the AHS series feature an extremely rugged available in three sizes with housing that is suitable for higher discharge pressures. used for every application under heavy load conditions, from low psig), they can build up discharge pressures variable up to high pressure applications up yields a ratio of drive pressure/ ratio of drive pressure/discharge pressure discharge pressure of more than 1:2. The the corresponding air pressure has to be supplied, typical...

AHD & AHS Series at a Glance Features & Benefits • Air-operated double-diaphragm pumps designed for a discharge pressure up to 15 bar (218 psig) • AHD Series (“D“ stands for Duplex) with internal pressure booster • AHS Series (“S“ stands for Simplex) without internal pressure booster, for using with an external booster • Corrosion-proof and wear-resistant housing in solid design made of polyethylene for heavy-duty applications • Double-acting principle of operation • Gentle displacement by compressible drive medium • Maximum capacities of 4, 10 and 20 m³/h (17, 44 and 87 gpm) for AHD pumps...

Special Development for Filter Press Feeding In many industrial processes, substances occur in aqueous muddy form, where the liquid portion must be removed. This can be in production processes, for example in the filtration of edible oils or yeast solutions, but more frequently at the end of a process in waste sludge from various industries from surface finishes to wastewater treatment. The disposal of such sludge is frequently done by compression and drying in a filter press. The AHD Series has been specially developed for feeding filter presses with chemical waste and special sludge. With...

Wear Resistant Housing Material & Solid Design All wetted housing parts are made of ultra-high-molecular-weight low pressure polyethylene (PE UHMW) in heavy solid design. PE competes with PP (polypropylene) which is frequently used in the manufacture of pumps. Thermally and chemically speaking, there are virtually no differences between these two. However, the similarity ends where the mechanical properties are concerned: trials based on the sand-slurry method have shown that the abrasion resistance of the PE (upper material sample) is 7 times higher than that of PP (middle material sample)...

Spare part kits S for pumps of the AHD/AHS series are compiled for single-shift operation (8 hours per day). These kits ensure that the correct replacement parts are always available in the required quantities. This helps to avoid production stoppages and ensures that the Almatec pumps are always ready for action. Besides, it is cheaper to buy spare parts as a kit than individually. The standard configuration of the suction and discharge ports are according to the illustration: Discharge port to the top, suction port forward. Pump size Dimensions: Width Depth Height Flange connections Air...
