Qdos metering pump

Overview

Qdos chemical metering pumps

Delivering flow rates that remain constant right up to 7 bar Qdos peristaltic chemical metering pumps give users a unique advantage over diaphragm metering pumps.

Qdos pumps offer long maintenance intervals - reducing the impact of process downtime and lowering the overall cost of ownership.

Eliminate ancillary equipment

A diaphragm metering pump often requires a range of high maintenance ancillary items to function.

Qdos pumps eliminate the need for ancillary equipment while ensuring accurate, linear and repeatable metering across all process conditions.

Pumpheads

Reduced maintenance with single, no-tools, component replacement

Industry leading ReNu and CWT pumphead technology is at the core of the Qdos pump. This ensures the delivery of accurate and repeatable flow for fluids of wide ranging viscosities.

ReNu and CWT pumpheads provides accurate, linear and repeatable low pulse flow under varying process conditions.

Safe, no tools maintenance plus an integral leak detector which eliminates operator exposure to chemicals.

Qdos pumps can be ordered with the ReNu or CWT pumphead mounted on the left or right side of the pump.
