Qdos Chemical Metering Pumps

Manufacturer: Watson-Marlow

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.

Cut chemical cost through higher accuracy metering
Simple drop-in installation eliminates ancillary equipment
Reduced maintenance with single, no-tools, component replacement
Cost of ownership is less than that of a diaphragm pump
