Pneumatic Diaphragm Centrifuge Feed Pump

Air-operated diaphragm pump used to feed oil into the centrifuge inlet at a controlled, metered rate. The ideal feed pump for US Filtermaxx centrifuge systems — delivers steady flow without emulsifying contaminants the way gear pumps can.

A key safety feature: when the centrifuge inlet is closed or the downstream line is blocked, the pump automatically stops pumping — no pressure buildup, no overload, no damage. Open the line and it resumes immediately.

Flow rate is controlled by adjusting air pressure — lower pressure = lower flow. Dial in the exact feed rate for your oil type and centrifuge model without modifying any plumbing.

Key features:

• Feeds oil directly to centrifuge inlet at adjustable, metered flow
• Auto-stops when output is closed — safe, self-regulating operation
• Air-operated diaphragm — no motor required, no electrical connection
• Adjustable flow via air pressure — precise feed rate control
• Gentle on oil — does not shear or emulsify suspended contaminants
• Nitrile diaphragm — compatible with mineral oils, WMO, WVO, diesel and biodiesel
• Self-priming
• Reversible flow direction

Pair with a US Filtermaxx inline heater to pre-heat cold or viscous oil before centrifuging for maximum throughput.
