small gear pumps 0.19 to 2 cubic centimeters per revolution

The small gear pump features a simple yet highly efficient design, supporting a wide range of oil port and shaft extension options, leak-free shaft seals, and bi-directional pumping. It delivers stable hydraulic performance for logistics handling equipment and other demanding applications under varying operating conditions.

Working Principle

1. Working process:
   • Gears rotate, drawing liquid into the suction chamber.
   • Liquid is forced out by the gears and delivered to the system through the discharge chamber.
   • Precision meshing of the inner and outer gears prevents leakage and ensures high pressure output.
2. Characteristic Analysis:
   • Low noise: Precision gear meshing and material selection reduce friction and vibration for quiet operation.
   • High efficiency: Maintains high displacement and pressure even at low speeds for adaptability.
   • Long service life: Wear-resistant materials and precision design ensure durability during high-load operation.
   • Excellent low-speed performance: Provides stable displacement and pressure for precise flow control at low speeds.

Applicable Scenarios

1. Logistics handling equipment: Stable pressure and flow for hydraulic systems, conveyor belts, and elevating platforms.
2. Hydraulic systems: High pressure output is ideal for pressure transfer in hydraulic applications.
3. Bidirectional pump option: Supports bidirectional flow for systems requiring reversible hydraulic operation.

Technical Parameters

1. Displacement per revolution: 0.19 – 2 cm³/rev
2. Direction of rotation: D (clockwise), S (counterclockwise), R (bi-directional)
3. Minimum speed: 500 – 1000 r/min
4. Maximum speed: 3000 – 7000 r/min
5. Peak pressure: 210 – 250 bar

Common Selection Considerations

1. Port and shaft extension selection: Choose appropriate options for system access and installation compatibility.
2. Bidirectional vs. unidirectional pumps: Select bidirectional pump for applications requiring two-way liquid flow.
