Filter press pumps are often used in wastewater, food processing, and chemical plants for effective sludge dewatering. Slurries enter the filter press, which passes the mixture through a series of filters to remove water and form slurry “cakes,” reducing disposal costs for the resulting water and solid cake. This process is challenging to an industrial pump, since increasing backpressures and decreasing flow rates are produced by the filtration of the slurry through the filter press.
How Can Pitbull Pumps Can Handle the Pressure?
Conventional pumps often require frequent maintenance and experience high failure rates due to variable back pressures and flow rates, abrasion, clogging from inconsistent solids content, and just simply heavy usage. Pitbull Pumps are specially configured for filter press variable head conditions; they automatically cycle, slowing the cycle rate as the backpressure climbs. They will not over-cycle under low heads and can be left to dead-head indefinitely on a full filter press without stalling.
What Solids Can Our Filter Press Pumps Manage?
Filter press pumps must be able to handle large solids, heavy slurries and abrasive solids. Because of the Pitbull Pump’s simple pneumatic displacement operation, filter press slurries can flow through its wide-open passages without clogging. The filling and discharge action of the chamber means extremely low cycle rates, low erosion and allows the pump to handle a wide range of solids content and discharge pressures. The pump cycling action of the Pitbull Pump is naturally de-clogging, dislodging solids that may be retained in the check valves. And, since there are no moving parts or motors combined with low velocities, little wear occurs when pumping abrasive particles.
