Peristaltic Pumps in Filter Presses

Verderflex hose pump reduces cost in filter press operation All water treatment plants produce waste, which has to be prepared for disposal, usually by filter pressing to minimize volumes and constrain the waste processing costs. Usually such waste is sent to landfill or incinerated giving a disposal cost based on the waste’s weight and volume. Why use a peristaltic hose pump in a filter press? Filter presses need special pumps: the waste is abrasive, so if you use a progressing cavity pump the waste causes stator wear, slip and consequentially the pump’s flow will drop. On the other hand when using a peristaltic tube pump will this hose pump will not have damage of wear, because the only part that is in contact with the waste water is the hose. The more over, our industrial hose pump eliminates “rat holes” (=water pulled from above the top of the sludge blanket). These rat holes are a problem that also occurs when pumping waste water in the filter press feed with a progressing cavity pump, thus increasing the water content (=the weight) and the volume of the pressed waste. With a Verderflex peristaltic hose pump you eliminate wear (the hose is the only wearing part), the waste is pressed better thus less weighing and cost will be reduced enormously.
