CMP Slurry

Chemical-Mechanical Planarization (CMP) Slurry

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.
