Easy to install and maintain
The Qdos 60 is added to the portfolio
Watson-Marlow Pumps Group has introduced the Qdos 60 peristaltic metering pump, which is designed to save costs in chemical metering applications owing to its higher accuracy metering.
The addition of Qdos 60 expands the company's range to incorporate flow rates from 0.1 to 1,000ml/min (0.001 to 15 USGPH) at 7 bar (100psi).
Furthermore, it is simple to install and offers easy, tool-free maintenance.
With the market demanding cost effective systems offering low operational expenditure, Qdos 60 negates the need for ancillaries, boosts productivity and cuts chemical wastage through more accurate, linear and repeatable metering than conventional solenoid or stepper-driven diaphragm metering pumps. As a result, Qdos 60 is able to reduce chemical costs even when metering difficult fluids, or when pressure, viscosity and solids content vary. This capability combines with peristaltic technology to ensures precise, continuous smooth flow for optimal fluid mixing, the company says.

Typical applications for Qdos 60 include disinfection, pH adjustment and flocculation of drinking water, wastewater and industrial process water, as well as reagent dosing/metering in mineral processing tasks. The new pump is especially suited to chemical metering applications found in larger water treatment plants where flow demand is greater than that provided by the existing Qdos 30 model. Advanced control features include fluid level monitoring, fluid recovery, line priming and intuitive flow calibration.
Installing the Qdos 60 drop-in pump requires no pulsation dampener, strainers or float switches, nor does it require any de-gassing, back-pressure or foot valves. In addition, there are no seals or valves in the Qdos 60 flow path to clog, leak or corrode, and there is no opportunity for vapour lock.
Watson-Marlow’s patented ReNu pumphead technology provides a single, safely contained component for rapid maintenance without the need for tools.
The pumphead can be configured on the left or right. Intuitive operation is facilitated through a menu-driven interface featuring a 3.5in TFT colour display with high visibility status indication. The keypad and display are positioned for easy access, along with input and output connections.
Engineers will also benefit from the ability to implement simplified system designs. The high suction lift and viscous handling capabilities of Qdos 60 eliminate the need for flooded suction, day tanks and specialist piping schemes.
