Overview
Operating Principle
Key Structural Components
-
Pump Casing: Constructed from high-quality aluminum alloy, it features a robust design that ensures durability while reducing overall weight. The casing integrates precision-machined fluid channels for optimal flow efficiency.
-
Gear Set: A pair of meshing involute gears that form the core working unit, responsible for fluid suction and discharge. The gears are engineered for wear resistance and smooth operation.
-
Driving Shaft: Adopts an involute spline design, ensuring secure power transmission and compatibility with various drive systems. The shaft is supported by high-performance bushings to minimize friction.
-
Sealing & Cover Assemblies: Front and rear covers seal the internal fluid path, while high-quality seals prevent leakage. This assembly also supports the shaft and ensures stable operation under high pressure.

-
Industrial vehicles: Steering systems and hydraulic cylinders for various mobile equipment.
Core Advantages
-
Durability: Aluminum alloy casing and wear-resistant components ensure a long service life under proper operation.
-
Stable Performance: Positive displacement mechanism delivers consistent flow and pressure, with a volumetric efficiency of 0.8 – 0.9.
-
Compact Design: Small size and light weight facilitate easy integration into space-constrained systems.
-
Cost-Effectiveness: Simple structure reduces maintenance requirements and overall ownership costs, with OEM/ODM services available.
Installation & Maintenance Notes
-
Select hydraulic oil that meets viscosity requirements and maintain oil cleanliness.
-
Ensure the installation dimensions comply with GSTU and GOST standards for compatibility.
-
Regularly inspect seals and bushings for leakage or wear, and replace them promptly if damaged.
-
Avoid operating the pump beyond the specified pressure and speed limits to prevent component failure.

Process steps：
Customer inquiry: Customers will make inquiries before placing an order to understand product details and communication needs.
Quotation: According to customer needs, provide a formal quotation, including the name, model, quantity, delivery time, payment method, etc. of the goods.
Order confirmation: After the customer confirms the quotation, a formal purchase order will be placed.
Confirm the delivery time: communicate the delivery time with the production department, inform the factory of the order details, and arrange the production plan.
Sign an export contract: After the two parties confirm that it is correct, sign an export contract to establish a trade relationship.
Implement the letter of credit (if applicable): If the payment method of the letter of credit is used, the customer needs to be urged to issue the certificate and review the contents of the letter of credit.
Export stocking: According to the requirements of the contract and the letter of credit, arrange production, purchase raw materials and packaging, and prepare the goods.
Chartering and booking: Contact the freight forwarder to make a booking and arrange the transportation of goods.
Export inspection: Apply to the quality inspection department for export commodity inspection and provide relevant documents.
Apply for a write-off slip: apply for a write-off slip from the foreign exchange management department for subsequent foreign exchange write-off.
Export declaration: Declare exports to the customs and provide documents such as power of attorney for customs declaration, customs declaration form for export goods, commercial invoice, packing list, etc.
