White Knight Metering Pumps for Chemical Dispense

Metering Pumps

Pneumatic metering pumps and electronic metering pumps feature PTFE flow paths and accurately dispense up to 100 ml and 50 ml, respectively. Their fully-supported rolling diaphragms maximize pressure capabilities and ensure safe, reliable chemical dispense.

Metering Pumps
White Knight PPMC Mini-Pump for High-Purity Chemicals

Mini-Pump

Mini pumps are capable of up to 300 ml/min flow rates and 160 psi discharge pressures. They feature PTFE and PFA fluid paths, and spring-loaded checks enable the pump to mount in any direction. Solenoid valves actuate each suction and dispense.
