PSG adds redesigned models to its peristaltic hose pump line for mining industry
PSG, a Dover company and a pumps and flow control solutions manufacturer, has designed new models of its Abaque Series peristaltic hose pumps specifically for the mining industry
The new models include a stronger and more durable rotor design and patented hose holding system to manage the challenging requirements of mining applications.
Featuring a seal-less design that eliminates leaks and product contamination, Abaque pumps are well-suited for a variety of mining applications, including wastewater, slurry transfer, thickener underflow, recirculation, reagent dosing, froth flotation, cyanide processing, and filter press.
The pumps contain no moving parts that come into contact with the product, making them able to handle slurries that contain up to 80% solids.
The self-priming pumps can run in forward or reverse and offer suction-lift capabilities to 9m, 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 15 bar.
The Abaque Series’ pumping action is achieved by compression of a circular loop of elastomeric hose with two diametrically opposed rotating shoes that force 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.
The working principle allows the pumps to feature high performance, low water consumption, reduced downtime, low maintenance costs, increased reliability and the ability to handle extremely abrasive and aggressive fluids.
The hoses are available in natural rubber (highly resilient with good 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 77,000l/hr.
