High-Purity Bellows Pumps

Reliable, metal-free pumps with PTFE/PFA flow paths

White Knight Pumps for Semiconductor Fabrication

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.
