The launch of a new pumphead designed for use with the award-winning Qdos range of peristaltic metering pumps has been announced by Watson-Marlow Fluid Technology Group.

Qdos 20 with the ReNu™ PU pumphead offers repeatable flow of 28 l/hr at 4 bar (7.67gph at 60psi) for fluids of wide-ranging viscosity whilst metering accuracy is assured to ±1%.

The launch of the Qdos 20 ReNu PU responds to a growing worldwide demand for polymer dosing systems in wastewater treatment. The majority of these systems use polymers to dewater sludge to minimise its bulk, thus reducing the cost associated with the disposal and storage of the cake by up to 75%.

Users of the new pumphead already reveal significant process improvements for dosing polymers, when 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.

Moreover, the ReNu PU pumphead offers integral leak detection and chemical containment; an important point as cleaning up polymer spillages can be hazardous to operatives and time consuming.

ReNu PU pumphead Customer feedback

A major utility provider on Lake Michigan, Illinois has confirmed the suitability of the ReNu PU for the accurate dosing of polymer flocculants. The company had a requirement to clean-up wastewater run-off from a limestone quarry; installing a Qdos pump fitted with a ReNu PU pumphead allowed them to meet water quality standards with a low maintenance, reliable solution.

A major UK brewery is also able to testify to the pumphead’s effectiveness. The brewery used a diaphragm metering pump for polymer dosing.

However, the small non-return valve within the diaphragm pump would easily become blocked by the polymer. In turn, the pump would 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.

About us

Watson-Marlow Fluid Technology Group (WMFTG) peristaltic tube and hose pumps meet requirements including: value for money; low cost of ownership; reliability and ease of maintenance to the food and beverage, chemical, pharmaceutical, mining and many other industries.

We demonstrate how pumps deliver significant process efficiencies over the lifetime of the equipment. Whether performing flavouring addition in food processing, chemical metering in water treatment or mineral recovery, we have a solution which can cut pump downtime and reduce costs through higher accuracy metering and transfer. WMFTG has dedicated application engineers available to help customers make the right pump and tubing choice from a range providing microlitres per minute to 80 cubic metres per hour flow rates.

The only part of the pump to come into contact with the product is the tube or hose. This means there are no seals or valves that can wear or fail. Replacing the tube or hose can be performed quickly and safely. Peristaltic pump benefits include:

Total fluid containment with no seals No ancillaries Handle viscous and abrasive slurries and sludge Self-priming capability Dry running without damage to the pump In addition to their range of positive displacement pumps, Watson-Marlow Fluid Technology Group has added PTFE-lined chemical and industrial hoses to their range. Aflex hoses are reinforced to withstand the most severe conditions and use.
