Allweiler ASH-32 Peristaltic Positive Displacement Pump

Description

Applications:
In wastewater and clarification plants; the chemical and petrochemical industry; pulp, paper, and textile industry; soap and grease industry; construction; ceramics and montan industry; paints; meat and fish processing industry; tanneries, cosmetics, etc. Suitable for pumping and metering low-viscosity and high viscosity liquids, neutral or aggressive liquids, undiluted or abrasive liquids, liquids containing gases, liquids prone to foaming, also liquids with fibrous or solid particles.
Functionality:
Dry self-priming displacement pump without gaskets or valves. Pumping elements are the pump hose and rotor with sliders. As the rotor turns, two sliders (aligned at 180-degree from each other) alternately compress the pump hose and move the pumped liquid incrementally from the suction to the pressure side. The thick-wall, fabric-reinforced pump hose subsequently opens automatically, creating an under pressure situation that effects continuous suction. The pumped liquid passes through the pump hose without contacting mechanical components. The smooth flow results in a gentle pumping action without turbulence and emulsification. The direction of rotation can be reversed, thereby reversing the pumping direction.
