PPM100 Pneumatic Metering Pumps

Ultra-High Purity PTFE Dispense Pumps

White Knight PPM100 Pneumatic Metering Pumps

PPM100 pneumatic metering pumps offer high-pressure capabilities and PTFE fluid paths. They accurately dispense corrosive media up to 100 ml, and operate with a fully supported rolling diaphragm – maximizing discharge pressure capabilities. Two positive control valves ensure accuracy by eliminating variability that is typical of check valves.

*Optimized parameters improve repeatability. To maximize repeatability, minimize suction lift, optimize dispense nozzle setup, purge air from fluid chamber, and minimize inlet fluid pressure fluctuations. Tests conducted with water at ambient temperature. Dispense range measured at full stroke with maximum and minimum supply pressures at 80 and 60 PSI.
