WZHLCX Hand Drill Oil Pump — Drill-Operated Trochoid & Triangle Pump, 2 m Hose, 8 mm Shaft, Portable 3.7 L/min

The WZHLCX Hand Drill Oil Pump is a compact, drill-operated pumping kit that uses trochoid and triangle mechanisms to extract, transfer, and fill engine, gear, and hydraulic oils quickly and reliably.

This versatile manual pump pairs with an electric drill or wrench to speed oil maintenance jobs without bulky equipment. Built with two complementary internal pump types, it balances steady flow with strong suction for viscous fluids. Its lightweight, portable design and included 2 m hose make it practical for garage work, farm machinery service, and on-site industrial tasks.

How does the dual pump design improve oil transfer?

The combination of trochoid and triangle pumping elements delivers consistent displacement while handling thicker lubricants. Trochoid gears provide smooth, low-pulse flow, while the triangle (rotor-stator-like) element improves suction and throughput for denser oils.

• Theoretical displacement: 2.5 ml per revolution for accurate metering
• Maximum speed compatibility: designed to work at drill speeds around 1500 r/min
• Output capability: approximately 3.7 L/min under recommended conditions
• Suction lift: up to 2.5 meters vertical for convenient extraction from low-slung sumps

Can I use this with my electric drill or impact wrench?

Yes — the pump is designed for simple drive coupling to common power tools. The shaft diameter is 8 mm and fits most drills; it also accepts hexagonal replacements so electric wrenches can be used for faster operation.

• Direct 8 mm shaft for standard electric drills
• Interchangeable shaft adapters accommodate hex bits for impact wrenches
• Lightweight 0.6 kg body (pipes excluded) keeps tool balance manageable

What fluids work best and what should I avoid?

The pump handles oils and other lubricants with moderate to high viscosity — engine oil, gear oil, and hydraulic fluid are all suitable. It is not intended for pumping clean water or very low-viscosity solvents, which reduce efficiency and may bypass the internal seals.

• Recommended: engine oil, gear oil, hydraulic oil and similar lubricants
• Not supported: clean water and thin non-lubricating liquids
• Designed to perform better with fluids that provide internal sealing and film strength

What comes in the kit and how easy is it to store?

The pump ships with a 2-meter hose (13 mm inner diameter) and the core pump assembly ready to attach to a power tool. Its compact footprint makes it easy to keep in a service trolley, trunk, or workshop drawer so it’s available for routine maintenance or emergency transfers.

• Includes 2 m x 13 mm ID hose for reach and flexibility
• Compact, durable housing that resists workshop wear
• Simple hookup to drills or wrenches for rapid deployment

Who this is for: The WZHLCX Hand Drill Oil Pump suits professional mechanics, fleet technicians, agricultural equipment operators, and DIYers who need a portable, tool-driven solution for oil extraction and filling. If you want a lightweight, adaptable pump that works with existing power tools and performs well with lubricating fluids, this kit is built to speed routine maintenance without large stationary equipment.
