Peristaltic (Hose) Pumps from Abaque™, a product brand of PSG®, Oakbrook Terrace, Ill., a Dover company, transfer difficult-to-handle chemicals and fluids.

For more than 20 years, Peristaltic (Hose) Pumps from Abaque™, a product brand of Oakbrook Terrace, Ill.-based PSG^®, a Dover company, have transferred difficult-to-handle chemicals and fluids.

The key to the success of the Abaque pumps in handling these diverse fluid characteristics and operating conditions is the peristaltic pumping principle:

High Performance: The pump’s seal-less design eliminates leaks and the possibility of product contamination, while providing the ability for continuous dry-run operation without adversely affecting pump performance, pressure and dosing accuracy.
Reliability: Peristaltic (hose) pump design requires none of the seats, valves, and mechanical seals that can fail on other pump styles; the pump hose is the only replacement part.
Versatility: The peristaltic pump can successfully handle extremely abrasive and aggressive fluids, solid-laden slurries, and water-thin, shear-sensitive and viscous materials.

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. WW
