Features of the Qdos range

Simplicity in installation, operation and maintenance were key considerations when designing the Qdos range of pumps.
An intuitive menu offers advanced control features including:

  • Fluid level monitoring
  • Line priming
  • Flow calibration

The 3.5″ TFT colour display provides instant pump status, and can be configured to display in 7 different languages.
Qdos pumps can be ordered with the ReNu pumphead mounted on the left or right of the pump. The keypad, display and input/output connections are readily accessible for easy operation and maintenance. All models are IP66 (NEMA 4X) rated for use in washdown environments.

Eliminate ancillary equipment

A diaphragm metering pump often requires a range of high maintenance ancillary items to function. The no-valve Qdos 30 eliminates ancillary equipment while ensuring accurate, linear and repeatable
metering across all process conditions.

  • No backpressure valves
  • No pulsation dampener
  • No degassing valves
  • No foot valves and strainers
  • No fl oat switches

 

Cost of ownership is less than a diaphragm pump

Qdos 30 delivers fl ow rates that remain constant.right up to 7 bar (100 psi) giving users a unique advantage over diaphragm metering pumps. Designed as a drop in replacement to diaphragm metering pumps, the Qdos 30 pump offers long maintenance intervals, reducing the impact of process downtime and lowering the overall cost of ownership.
