Qdos Chemical 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

500 Series Peristaltic Pumps with LoadSure Elements
530 Series Cased Drive Pumps: Up to 55.48 GPH, Up to 100 psi, 2200:1 Speed Control Range.
521 Series Direct Coupled Pumps: 0.08 Ounces a Minute to 17.6 gpm, Up to 101.5 psi, 10:1 Turn Down and Variable Speed Drive Options
Available with a range of drive, control, and enclosure options in both industrial and sanitary versions. Highly accurate, sealless, low pulsing pumps with available LoadSure Elements. LoadSure Elements make changing hose error free and quick (a minute or less). The extremely low-shear pump action allows you to move product without degradation or damage. There is no need to worry about the high velocities and arduous flow paths associated with impellers, vanes, lobes or valves in other pump types that can damage the product. We know that pump failure during production cannot be tolerated due to the intrinsic value of the product. That is why we design our drives to be maintenance-free. We utilize spring-loaded rollers and tracks to provide long and repeatable tube life too.
