Products for Semiconductor Manufacturing and Fabrication

High-Purity Pumps, Closed-Loop Systems, & Accessories

White Knight Pumps

White Knight high-purity pumps enable semiconductor manufacturers to build smaller circuits at lower costs. Our pumps are built on decades of innovative engineering and in-house manufacturing. They offer safe, reliable operation with low maintenance even in the harshest and most demanding environments.

White Knight bellows pumps, diaphragm pumps, and metering pumps deliver, circulate, reclaim and transport high-purity chemicals for semiconductor fabrication.

White Knight High-Purity Pneumatic Bellows Pumps

Bellows Pumps

Ultra-pure air-operated double-bellows pumps (AODB pumps) feature PTFE/PFA flow paths. These reliable, leak-free pumps offer high flow rates, steady pressures and stable temperatures. They do not contain metals, elastomer O-rings, impellers or electric motors. They are dead-head capable, and provide high suction lift.

White Knight High-Purity Air-Operated Double-Diaphram Pumps

Diaphragm Pumps

High-purity air-operated double-diaphragm pumps (AODD pumps) feature PTFE or UHMW (PE) corrosion-resistant fluid paths. These safe, reliable pumps offer superior performance and simple maintenance. PSB Series AODD pumps are direct retrofit replacements for obsolete chemical delivery pumps.

Diaphragm Pumps
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 for chemical replenishing, blending, dosing and spiking.
