Built to handle viscous lubricants rather than water, it pairs a small footprint with robust internals to move oil efficiently — supporting extraction, filling, and fluid replacement tasks across automotive and industrial equipment. The unit is lightweight, easy to mount, and supplied with a 2 m hose and a direct 8 mm shaft that accepts common drills; the shaft can be swapped for a hex screw to use an electric wrench.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the pump move oil and what are its performance figures?\u003c\/h3\u003e\n\u003cp\u003eTwo positive-displacement designs — trochoid and triangle rotor types — provide steady, low-pulse flow suited to lubricants. The theoretical displacement is 2.5 ml per revolution; at 1500 rpm the pump yields about 3.7 L\/min and generates a suction up to 0.1 MPa, allowing vertical lift up to roughly 2.5 meters.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDual pump mechanisms for reliable, low-pulse flow\u003c\/li\u003e\n  \u003cli\u003e2.5 ml per revolution displacement for predictable dosing\u003c\/li\u003e\n  \u003cli\u003e~3.7 L\/min output at 1500 rpm for faster transfers\u003c\/li\u003e\n  \u003cli\u003e0.1 MPa suction and 2.5 m vertical lift for deep-sump reach\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat fluids can it handle and what should I avoid?\u003c\/h3\u003e\n\u003cp\u003eThe unit is optimized for oils and other fluids with measurable viscosity — engine oils, gear oils, and hydraulic fluids — where internal clearances and rotor geometry maintain performance.
