Qdos chemical metering pumps
Accurate, versatile 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.
Delivering flow rates that remain constant right up to 7bar 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.
- - Cut chemical cost through higher accuracy metering
- - Simple drop-in installation eliminates ancillary equipment
- - Reduced maintenance with single, no-tools, component replacement
- - Flow rates from 0.1 to 2,000ml/min at up to 7 bar
- - Cost of ownership is less than that of a diaphragm pump
Eliminate ancillary equipment
A diaphragm metering pump often requires a range of high maintenance ancillary items to function.
The Qdos pump 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 float switches
Total cost of ownership is less than a diaphragm pump

- Qdos chemical metering pumps 26/02/2013 15:13:00Accurate, versatile 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.
- Bredel hose pumps 26/02/2013 15:21:00Bredel heavy-duty hose pumps handle abrasive sludge, paste, and slurries at 100% volumetric accuracy. Unlike diaphragm, rotary lobe, and PC pumps, no moving parts come into contact with the product, and there are no mechanical seals. They completely contain the pumped fluid in a long-life hose, preventing operator contact with chemicals, slurries or sludge. Every Bredel hose is precision machined to ensure flow stability and pump performance in tough fluid handling applications.
