The HP-01 Manual Hand Pump with Meter is designed for controlled liquid transfer and dispensing in oil depots, fuel stations, agricultural machinery facilities, workshops, and industrial maintenance environments. Its cast iron construction and manually operated mechanism support routine transfer tasks, while the integrated 25 mm zero-return metering configuration helps users monitor the quantity of liquid dispensed. With a catalog-listed flow rate of 35–55 L/min, a lift range of 15–20 m, and a suction range of 3–4 m, the HP-01 offers a manual pumping solution for compatible liquids. Confirm the meter specifications, approved fluids, and actual operating limits before selecting the pump for a specific application.

Integrated Liquid Measurement
The HP-01 is described as having a 25 mm zero-return metering configuration. This can help operators monitor dispensing quantities during routine liquid transfer. Confirm the meter’s measurement range, accuracy, reset method, and compatibility with the intended liquid before ordering.
Manual Liquid Dispensing
Manual operation allows the pump to be used without an electric power connection, making it suitable for selected maintenance and dispensing tasks where powered equipment is not required.
Robust Cast Iron Construction
The cast iron pump body is intended for suitable operating environments where a metal construction is preferred. The compatibility of the body, seals, meter, and other liquid-contact components must be checked for each application.
Wheeled Support for Mobility
The frame and wheels shown in the product image can make it easier to reposition the unit around a suitable workshop or dispensing area. Confirm the final supplied configuration and mobility requirements when specifying the product.
Suitable for Routine Industrial Dispensing
The HP-01 is intended for oil depots, workshops, agricultural facilities, and other locations that need manually operated liquid transfer with metering. Application suitability depends on the liquid, required output, and the verified operating limits.
The HP-01 is designed for manually transferring and dispensing compatible liquids while monitoring the quantity delivered through its metering configuration. The catalog identifies oil depots, fuel stations, agricultural machinery facilities, workshops, and industrial environments as potential applications. The pump should be selected according to the liquid, operating conditions, and verified meter specifications.
The catalog lists a flow rate of 35–55 L/min. The actual transfer rate depends on liquid viscosity, suction conditions, delivery height, line resistance, and the operator’s pumping rate. A higher flow rate can reduce transfer time, but buyers should confirm realistic output under their intended working conditions before estimating dispensing capacity.
The product description identifies a 25 mm zero-return metering configuration. A zero-return meter generally allows the displayed quantity to be reset for a new dispensing operation. However, the supplied catalog does not establish the meter’s accuracy, measurement range, unit options, or calibration procedure. Confirm these details with the manufacturer if the meter will be used for inventory management or quantity-based transactions.
The supplied description refers to manual pumps suitable for clean water, gasoline, kerosene, and other liquids that do not corrode iron or copper. Because the HP-01 uses cast iron construction and includes a meter and additional liquid-contact components, this general description does not establish complete compatibility for every fluid. Confirm the approved fluid list with the manufacturer. For gasoline or other flammable liquids, use only equipment specifically approved for that service and follow the applicable safety requirements.
Confirm the intended liquid, required flow rate, suction conditions, transfer height, outlet connection, meter accuracy, and the compatibility of all wetted components. The catalog lists a 1-inch outlet, a 15–20 m lift range, and a 3–4 m suction range. Ask the manufacturer to clarify the test conditions behind these figures and verify that the metering system meets the requirements of the intended application.
HP01 hand pump is suitable for use in small and medium-sized oil depots, gas stations, agricultural machinery stations, enterprises, mines, fleets, vehicles, ships, airports, and other units in various regions. The pump has a compact structure, small size, light weight, convenient movement, and simple operation. It only requires one person to manually shake the handle back and forth to continuously dispense oil. This pump is equipped with a 25mm metering meter (pointer can return to zero), and a 1-inch refueling gun can be used to switch at the outlet of the hose, avoiding waste of accumulated oil in the hose when it stops working.
