Pumps for CMP Polishing
White Knight’s high-purity pumps feature Pneumatic Logic™, which reduces pulsation to prevent shear while gently pumping slurry. The pumps have long life spans and have been proven to operate reliably in the most demanding chemical environments.
PSD Series air-operated double-diaphragm (AODD) pumps feature UHMW (PE) fluid paths to allow for longer lifespans in abrasive slurry.
PSA Series Pumps
White Knight PSA060 and PSA140 pumps offer flow rates up to 60 lpm (16 gpm) and 140 lpm (36 gpm), respectively. They are capable of up to 7 Bar (100 psi) air supply pressures and fluid temperatures up to 100°C (212°F). They contain no metals and feature Teflon® PTFE and PFA fluid paths. See PSA Series for details.
PSD Series Pumps
White Knight PSD Series pumps offer economical bulk transport of corrosive chemicals. The 1/2-inch PSD08, 1-inch PSD16, and 1-1/2-inch PSD24 are capable of pumping up to 60 lpm (16 gpm), 140 lpm (36 gpm), and 320 lpm (85 gpm), respectively. See PSD Series for details.
