WZHLCX Self-Priming Drill-Driven Gear Oil Pump — Cast-Iron Body, 2m Silicone Hose, 3.5 L/min

WZHLCX self-priming oil pump is a compact, drill-driven gear pump that quickly evacuates engine, transmission, and hydraulic oils for routine maintenance.

This pump converts a standard electric drill or wrench into a high-efficiency oil extractor so you can remove used lubricants without crawling under vehicles or relying on messy manual suction. Built with a cast-iron cycloid pump body, dual shaft sleeve options, and a long oil-resistant silicone hose, it is engineered for recurring workshop or DIY maintenance tasks where speed, durability, and portability matter.

How does this pump attach to my drill or electric wrench?

Connection is straightforward: choose the sleeve that matches your tool’s chuck or drive, secure the coupling, and clamp the silicone hose to the outlet. The pump runs directly from the tool’s rotational output—no separate motor required—so setup takes only a few minutes.

• Includes two adapter sleeves (8mm and 12mm) for common drill wrenches.
• Supplied 1/2-inch 12mm socket and 8mm coupling for secure drive fit.
• Two hose clamps and Baota connectors for leak-free hose installation.

What flow and suction performance can I expect?

At a typical tool speed of 1,800 rpm the pump delivers around 3.5 L/min and can achieve up to a 3-meter vertical lift, making it suitable for standard oil changes and fluid transfers. Performance depends on tool RPM and fluid viscosity; heavier oils or lower tool speeds will reduce flow.

• Rated flow: approximately 3.5 liters per minute at 1,800 rpm.
• Maximum vertical suction lift: up to 3 meters under ideal conditions.
• Handles engine, transmission, and hydraulic oils within typical maintenance viscosities.

What materials and parts come with the pump, and how durable is it?

The core pump housing is cast iron for wear resistance and long service life; the kit includes a cycloid pump, silicone hose, adapters and clamps so you receive a ready-to-use assembly. The included 2-meter silicone hose is oil-resistant and designed to resist aging from repeated use.

• Main body: high-strength cast iron for abrasion resistance.
• Standard 2 m silicone hose with 12 mm inner diameter for oil resistance.
• Complete accessory set: cycloid pump, Baota connectors, socket, couplings, and clamps.

How easy is it to operate and maintain over time?

Operation is minimal: mount the pump to your drill, connect hose and fittings, immerse the suction tube, and run the tool. Routine maintenance is likewise simple—inspect hose and clamps, keep the cycloid pump free of debris, and replace worn sleeves or clamps as needed to preserve sealing and performance.

• Quick install: clamp and couple in minutes, then start with your electric tool.
• Low upkeep: periodic hose and clamp checks; occasional pump inspection.
• Parts are user-replaceable for extended service life.

Who is this for: technicians and DIYers who need a fast, portable, and durable oil extraction solution for cars, light trucks, and mechanical equipment. If you perform routine fluid changes in a garage, small shop, or field setting and value a tool that uses equipment you already own (drill or wrench), this WZHLCX self-priming oil pump speeds up oil removal while reducing mess and physical strain. It is not intended as a medical device or for pumping combustible solvents; choose oils and applications consistent with the pump’s materials and rated flow.
