Oakbrook Terrace a Dover company and a global leader in the manufacture of pumps, systems and related flow-control solutions, is pleased to announce that new models of its Abaque™ Series Peristaltic (Hose) Pumps have been specifically designed to meet the challenging requirements of the mining industry, thanks in part to its stronger and more durable rotor design and patented hose holding system.

Featuring a seal-less design that eliminates leaks and product contamination, Abaque pumps are ideally suited for a wide variety of mining applications, including wastewater, slurry transfer, thickener underflow, recirculation, reagent dosing, froth flotation, cyanide processing and filter press. With no moving parts that come into contact with the product and the ability to handle slurries that contain up to 80% solids with ease, Abaque pumps offer significant advantages over competitive pumps. These self-priming pumps can run in forward or reverse and offer suction-lift capabilities to 25.5 feet (9 meters), as well as the ability to run dry without adversely affecting performance, pressure and accuracy (no slip). Abaque pumps are constructed of ductile iron and stainless steel, allowing higher discharge pressure to 217 psi (15 bar).

The Abaque Series’ pumping action is achieved by compression of a circular loop of elastomeric hose with two diametrically opposed rotating shoes. This rotational motion forces the fluid in the hose to move ahead of each shoe. When each shoe reaches the end of the loop, the reinforced hose immediately returns to its original shape, ensuring suction and priming, creating a strong vacuum pulling more fluid inside. This results in a pump that features higher performance, lower water consumption, reduced downtime, lower maintenance costs, increased reliability and the ability to handle the toughest pumping challenges, including extremely abrasive and aggressive fluids.

The hoses are available in natural rubber (highly resilient with excellent abrasion resistance and strength), Buna-N (highly wear resistant to oily products), EPDM (high chemical resistance when handling concentrated acids, alcohols and ketones) and Hypalon® (resistant to chemicals, temperature extremes and ultraviolet light). Abaque pumps are available in 13 different sizes, with flow rates ranging from 15 to 77,000 L/hr (.07 to 339 gpm).
