Making The Case
Peristaltic (hose) pumps stand out because their operation is based on the alternating contraction and relaxation of the hose, which forces the contents to move through the pump and into the discharge piping. The smooth-wall, flexible hose is squeezed between shoes on the rotor and the inside of the pump casing. This rotation moves the product through the hose at a constant displacement rate. The hose restitution after the squeeze produces an almost full vacuum that draws more product into the hose from the intake piping. The pumped product only contacts the hose and inserts, making this pumping technology very suitable for abrasive and corrosive applications.
Peristaltic (hose) pumps also maintain excellent volumetric consistency, making them ideal for the strict dosing and 24/7 operating cycles that can be required in wastewater-treatment applications. Peristaltic (hose) pumps are also easy to operate and maintain, and their reversible operation allows for pumping in both directions, if needed.
In order to successfully handle the challenges of wastewater treatment, the pump’s hose and inserts need to offer the highest level of material compatibility, while also being able to reliably deliver the millions of pumping cycles that are required during their lifetimes.
A critical consideration when selecting the hose material is its "fatigue resistance." This trait defines how resistant to failure the hose material is as it runs through its millions of pumping cycles. A hose material that is susceptible to developing cracks and holes early in its operational life is not as desirable as a material that can reliably handle the demands of the repeated contraction and relaxation of the hose, especially when particulate-laden liquids are being pumped. The reinforced construction of the peristaltic hose and its use of rubber compositions (natural rubber, EPDM, Buna®-N, etc.) that have been specially designed for the stresses within the peristaltic hose allow for the optimum life cycle and performance.
For more than two decades, peristaltic (hose) pump technology – as epitomized by the standard-setting operation of the Abaque® Peristaltic (Hose) Pump family – has proven to offer the performance and reliability that can make it a first-choice pumping option for wastewater treaters who crave highly reliable, environmentally friendly, low-maintenance pump operation.
