Watson-Marlow Fluid Technology Solutions highlights full range of Bredel heavy-duty hose pumps and Qdos reagent feed pumps for demanding mining applications

Watson-Marlow Fluid Technology Solutions (WMFTS) highlights their full range of Bredel and Qdos peristaltic pumps, ideal for mining’s most demanding transfer & metering applications. WMFTS will showcase these solutions in booth #10565 at MINExpo September 24th - 26th at the Las Vegas Convention Center in Las Vegas, Nevada.

Bredel hose pumps have a proven ability to handle abrasive pastes and chemicals, including viscous slurries, grit-filled sludge, corrosive acids, and other challenging materials. These industrial pumps achieve flow rates of up to 475 gallons per minute, transferring up to 80 percent solids in suspension. Qdos chemical metering pumps, with the ReNu cartridge pumphead at the core of its operation, meters reagents in thousands of mining installations worldwide.

Mines around the world are replacing centrifugal pumps with hose pumps, which are far less affected by such fluid dynamics as paste density, viscosity, suction conditions, and discharge pressure. Hose pumps are also unaffected by the abrasive and aggressive nature of paste and chemicals. Unlike centrifugal and progressing cavity pumps, the peristaltic design of Bredel hose and Qdos metering pumps contain no moving parts that come into contact with the product with no seals, ball-checks, diaphragms, glands, immersed rotors, stators or pistons to leak, clog, corrode or replace.

Bredel & Qdos pumps also eliminate the need for ancillary equipment, including dry-run protection and seal water flush systems. A simple replacement hose or cartridge change takes only minutes or even seconds and can be performed in-situ without special tools or skilled personnel.

The low maintenance peristaltic design offers a low total cost of ownership. As the fluid is safely contained within the pump, operation and maintenance personnel and the environment are protected from unwanted spillages or exposure to chemicals.

Bredel & Qdos pumps are dry-running, self-priming and allow no slippage for true positive displacement to provide accurate and repeatable metering. Flow is entirely independent of suction and discharge conditions.

The new Qdos H-FLO enhances the range of Qdos pumps by offering flow rates up to 158 gallons per hour (600 L/h) and pressure capability up to 102 psi (7 bar). Like the rest of the Qdos range of peristaltic pumps, Qdos H-FLO cuts costs through higher precision chemical metering, with an accuracy of ±1% and repeatability of ±0.5% in dosing.
