Watson-Marlow Announces ReNu™ PU Pumphead Designed for Use with Qdos 20 Pump
Watson-Marlow Fluid Technology Group, the world leader in peristaltic pumps and associated fluid path technologies, announces the launch of the new ReNu™ PU pumphead, specially designed for use with the award-winning Qdos range of peristaltic metering pumps. The ReNu PU pumphead offers repeatable flow of 7.67 gallons per hour at 60 pounds per square inch (28 liters per hour at 4 bar), for fluids of wide-ranging viscosity. Metering accuracy is assured to ±1 percent. The pumphead has successfully been used at a variety of facilities around the world, including a major utility provider in Illinois.
The launch of the Qdos 20 ReNu PU responds to a growing worldwide demand for wastewater treatment polymer dosing systems. The majority of these systems use polymers to dewater sludge to minimize its bulk, thus reducing the cost associated with the disposal and storage of the cake by up to 75 percent. Users of the new pumphead have already found significant process improvements for dosing polymers compared to diaphragm metering pumps.
The ReNu PU pumphead is designed to deliver maximum process uptime. This is facilitated by rapid, safe and easy pumphead removal and replacement. There is no need for specialist tools and no requirement for specially trained on-site maintenance technicians. The ReNu PU pumphead also offers integral leak detection and chemical containment, which reduces hazards associated and time associated with cleaning up polymer spillages.
A major utility provider on Lake Michigan, Illinois recently confirmed the ReNu PU’s suitability for accurate dosing of polymer flocculants. The company had a requirement to clean-up wastewater run-off from a limestone quarry, and installing a Qdos pump fitted with a ReNu PU pumphead allowed them to meet water quality standards with a low maintenance, reliable solution.
The pumphead was also used by a UK brewery that previously used a diaphragm metering pump for polymer dosing. The polymer frequently blocked the diaphragm pump’s small non-return valve, causing the pump to require frequent cleaning, a process made more challenging by the fluid’s high viscosity.
“We don’t have any such issues with the Qdos, which reliably doses polymer for around 12 hours every day,” says Mr Dave Burrows of SUEZ UK, who is responsible for the effluent plant at the brewery. “I really can’t fault the reliability or simplicity of the Qdos pump or the ReNu PU pumphead. In addition, when the pumphead reaches its end of life, you get a useful notification. Replacement is quick and easy – we’re up and running again with 5-10 minutes.” The Qdos 20 ReNu PU has proved a complete success, with no issues experienced over an extended period of time.
