2. Design & Structural Features
-
Construction Materials: The pump body is made of aluminum alloy for lightweight and corrosion resistance; the flange and rear cover adopt cast iron to ensure high rigidity and pressure resistance. Gears are designed as integral gear-shaft structure with 12 teeth, enhancing durability. DU bearings are used for high load capacity and wear resistance, and nitrile (NBR) seals are standard (Viton seals optional for high-temperature applications).
-
Performance Advantages: Equipped with floating bushes for axial compensation, maintaining high volumetric efficiency across different pressure ranges. It features quiet operation, suitable for noise-sensitive environments, and a compact, space-saving design that fits limited installation spaces. Every pump undergoes 100% hydraulic testing after assembly to ensure consistent performance.
-
Port & Mounting: Adopts European standard flanged ports; threaded ports are available but may reduce pump service life. The mounting complies with Group 3.5 standard flange, with SAE or other options available on request.
3. Operational Notes
-
Standard rotation direction: Clockwise (viewed from the shaft end); bidirectional rotation is available as a special version, but the maximum pressure must be reduced by 10% for bidirectional pumps.
-
If the pump operates exclusively under continuous pressure (P1), the maximum operating speed must be reduced by 10% to ensure stable performance.
-
Recommended inlet pressure: 0.2~0.5 bar (2.9~7.25 psi) for optimal efficiency.
-
Fluid Compatibility: Suitable for mineral oils and synthetic hydraulic fluids with a viscosity of 10~100 cSt at 40°C.
-
Application Scope: Widely used in mobile equipment (such as farm vehicles, snow plows, and lifts) and industrial hydraulic systems that require stable medium-pressure output.
