The launch of a new pumphead designed for use with the 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 (7.67 gph at 60 psi) for fluids of wide-ranging viscosity while metering accuracy is Source: Watson-Marlowassured 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 minimize 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.

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.
