Qdos Chemical Pumps
Watson-Marlow® Peristaltic Pumps
Delivering flow rates that remain constant right up to 100 psi Qdos peristaltic chemical metering pumps gives 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.
Features and benefits
- Cut chemical cost through higher accuracy metering
- Simple drop-in installation eliminates ancillary equipment
- Reduced maintenance with single, no-tools, component replacement
- The cost of ownership is less than that of a diaphragm pump
- Flow rates from 0.001 GPH (0.1 ml/min) to 31.7 GPH (2,000 ml/min) at up to 100 psi
- No backpressure valves, pulsation dampener, degassing valves, foot valves, strainers, or float switches
