No power supply is required. The pump runs using a standard hand drill as the drive. Compatibility - Works with hand drills rated above 100 W and with speeds above 1000 rpm. - Drill power and speed directly influence pumping performance: higher power and speed yield higher flow; lower power yields smaller flow. Performance and range - Our collection includes a wide range of pumps to suit different needs, including water pumps, power pumps, diaphragm pumps, fuel pumps, gear pumps, and more. This ensures you can find the right pump for your task without changing tools. Key attributes - Function: drill-powered pumping solution that converts drill torque into pumping action. - Compatibility: designed to work with common hand drills meeting the specified power and speed requirements. - Performance: flow rate scales with drill power and speed, allowing for flexible operation. - Size and material: offered across a broad range of pump types in our collection to fit various applications. Use scenarios - Quick water transfer in a workshop or garden, using a water pump attachment on a standard hand drill. - Fuel transfer or refueling tasks in locations without electricity, using a suitable fuel pump option. - Maintenance and servicing in a garage, such as transferring coolant or other fluids with a diaphragm or gear pump variant. This product line provides practical, drill-powered pumping solutions suitable for a variety of liquids and applications, with clear compatibility and performance expectations.
