{"product_id":"asm-grp-301","title":"Pneumatic Diaphragm Centrifuge Feed Pump","description":"\u003cp\u003eAir-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.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eFlow rate is controlled by adjusting air pressure — lower pressure = lower flow.
