Watson-Marlow Pumps Group is to launch its “novalve
metering revolution” at a major press event at Achema, today.
Making its global exhibition debut at the show is the revolutionary Qdos 30 pump
range. Developed in response to extensive industrial customer feedback for
improved chemical metering, the Qdos 30 eliminates ancillary equipment, enhances
productivity, and reduces chemical waste through more accurate, linear, and
repeatable metering than typical solenoid or stepper driven diaphragm metering
pumps. The Qdos 30 delivers an unrivaled 5,000:1 flow range from 0.1 – 500
ml/min and 7 bar while integrating easily through IP66 manual, analogue, and
PROFIBUS control options. Featuring patented ReNu pumphead technology, Qdos
30 is fully sealed for safe, tool-free maintenance.
Visitors to Stand D51, Hall 8.0 can learn how Qdos 30 pumps boost process efficiency by
providing accurate, linear and repeatable flow performance from 0.1 to 500 ml/min at 7
bar, even when metering difficult fluids when pressure, viscosity and solids content vary.
There are no seals or valves in the flow path to clog, leak or corrode.
This means that fluids that are caustic, abrasive, viscous, shear-sensitive, gaseous, are
slurries or contain suspended solids, can be safely and securely handled. Advanced
control features include fluid level monitoring, fluid recovery, line priming and intuitive flow calibration.
Design innovation
Developed in response to extensive customer feedback, Qdos 30 pumps feature Watson-
Marlow’s innovative ReNu pumphead technology. Quick and easy pumphead removal and
replacement minimises process downtime and requires no specialist tools, training or
technicians.
The pumphead can be configured on the left or right, making it ideal for installing in
restricted environments or on skids, while its sealed design and fluid recovery eliminate
wastage and ensures operator safety. Operation is intuitive via a menu-driven interface
with a 3.5″ TFT colour display, providing high-visibility status indication. The keypad and
display are positioned for easy access, along with input and output connections.
The premium model in the new range is the Qdos 30 Universal+. This impressive pump
offers features and functionality that set it apart from competitive diaphragm metering
pumps. For example, the pump response to the 4-20mA input signal is fully configurable,
and a 4-20mA output and alarm output is available.
Applications capability
Featuring all-new hardware and software, applications for Qdos 30 include: disinfection
and pH adjustment of drinking water and industrial process water; flocculation; industrial
cooling water preparation; and reagent dosing in mineral processing to name but a few.
The versatile pump design and range means customers can select the pump that meets
the precise application requirements. Maintenance intervals are up to an impressive six
months at typical usage, reducing the impact of process downtime.
In addition to the Qdos 30 Universal+ pump, four other variants are available.
