PSG has announced that new models of its Abaque™ Series Peristaltic (Hose) Pumps have been designed to meet the challenging requirements of the mining industry, due to its stronger and more durable rotor design and patented hose holding system.
Features include a seal-less design that eliminates leaks and product contamination. Abaque pumps are suited for a wide variety of mining applications, including wastewater, slurry transfer, thickener underflow, recirculation, reagent dosing, froth flotation, cyanide processing and filter press. The pumps have no moving parts that come into contact with the product and they have the ability to handle slurries that contain up to 80% solids with ease. These self-priming pumps can run in forward or reverse and offer suction-lift capabilities to 25.5 ft (9 m), 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 motion forces the fluid in the hose to move ahead of each shoe. Upon reaching the end of the loop, the reinforced hose immediately returns to its original shape. This results in a pump that can handle the toughest pumping challenges, including extremely abrasive and aggressive fluids.
The hoses are available in natural rubber, Buna-N, EPDM and Hypalon®. Abaque pumps are available in 13 different sizes, with flow rates ranging from 15 to 77 000 L/hr (.07 to 339 gpm).
