Reliable, metal-free pumps with PTFE/PFA flow paths
Overview
White Knight air-operated double-bellows pumps are used to manufacture semiconductors, photovoltaic solar cells, LEDs, flat-panel displays and electronics. These high-purity chemical pumps feature PTFE/PFA fluid paths. They do not contain metals, elastomer O-rings, or electric motors. Their reliable designs use minimal parts, and operate continuously throughout their warranty period with no required maintenance.
LHA Series pumps offer steady, laminar flow rates up to 30 lpm and feature process-safe PTFE/PFA flow paths. They are capable of up to 100°C (212°F) fluid temperatures, 5.5 Bar (80 psi) air supply pressures, and 3 m (10 ft) suction lift.
PXA Series Pumps Proximity Sensors ≤ 100°C (212°F) ≤ 7 Bar (100 psi)
PXH Series Pumps Proximity Sensors ≤ 145°C (293°F) ≤ 5.5 Bar (80 psi)
PXU Series Pumps Proximity Sensors ≤ 210°C (410°F) ≤ 7 Bar (100 psi)
Pump Configuration
Different Outlet Fittings
Please select outlet connection, fitting and size.
Configuration:
*Notes: Pumps with SP2, SP3, or SP5 pressure switch stroke detection come without shuttle valve. Pump operation in timer mode requires end-of-stroke detection (pressure switch) to prevent over-stroking. Operating pumps in timer mode without end-of-stroke detection voids the pump warranty. Do not use fiber optic stroke detection in applications over 135°C
*Notes: Fiber optics are required for operation. Standard configuration comes dual-probe WITHOUT fibers. Please see stroke detect option for fiber optic cables. Pump operation in timer mode requires end-of-stroke detection (fiber-optic stoke detection) to prevent over-stroking. Operating pump in timer mode without end-of-stroke detection voids pump warranty. Pump requires use of the included White Knight quick exhaust valves (QEVs) or QEVs supplied by the customer used with the optional NPT adapter. Operating pump without QEVs voids pump warranty.
*Notes: Proximity switch required for operation. Standard configuration comes WITHOUT proximity switch. Please see stroke detection options to order proximity switch. Pump operation in timer mode requires end-of-stroke detection (pressure switch stoke detection) to prevent over-stroking. Operating pump in timer mode without end-of-stroke detection voids pump warranty. Pump requires use of the included White Knight quick exhaust valves (QEVs) or QEVs supplied by the customer used with the optional NPT adapter. Operating pump without QEVs voids pump warranty.
