As a key connecting component of hydraulic power units, the motor pump flange base plays a crucial role in coaxially fixing the motor and hydraulic pump and positioning the entire machine frame. It is widely used in machine tool lubrication pumps, small hydraulic stations, and oil supply assemblies for automated equipment. Traditional cast iron bases are heavy, prone to corrosion, and have poor machining accuracy, easily leading to coaxial misalignment, equipment vibration, and abnormal noise. Ganyuan Hardware, leveraging the advantages of aluminum alloy raw materials and mature CNC machining technology, customizes and produces high-precision flange bases, addressing the shortcomings of traditional components from multiple dimensions including material, process, and customization.
The product uses ADC12 die-cast aluminum and 6061-T6 industrial aluminum alloy as raw materials. Compared to cast iron and cast steel, its weight is only 1/3 that of steel components, effectively reducing the overall load of the hydraulic unit and lowering equipment operating energy consumption. Aluminum alloys possess inherent antioxidant and rust-resistant properties, excellent toughness, and resistance to vibration and impact. They are less prone to cracking and deformation during long-term, high-frequency start-stop operation. Furthermore, the raw material procurement cost is significantly lower than that of brass castings, helping equipment manufacturers substantially reduce spare parts procurement and subsequent maintenance costs.
Exclusive CNC aluminum alloy motor pump flange base: connecting custom accessories
After the blank is die-cast, all processes utilize CNC turning, boring, end milling, drilling, and tapping for precision machining. One-time clamping avoids the cumulative errors of multiple machining processes. Internal hole dimensional tolerances are controlled to ±0.01mm, and coaxiality ≤0.02mm. High-precision internal hole positioning of the oil pump and precise alignment of the outer ring threaded hole with the motor end cover ensure perfect coaxial transmission between the motor output shaft and the oil pump drive shaft. This reduces operational vibration and friction noise at the source, extending the service life of the oil pump and motor seals, meeting the high-precision assembly requirements of industrial equipment.
Utilizing digital CNC programming technology, product specifications can be quickly switched by modifying the machining program without the need for dedicated die-casting molds. Single-piece sampling and large/small batch customization are supported. Non-standard internal splines, irregular flange hole positions, raised bases, eccentric mounting positions, and other special structures can be customized according to customer's oil pump model and motor installation standards. It is compatible with various pump types, including gear pumps, vane pumps, and lubrication pumps. Whether it's a standard universal model or a special irregular base for equipment modification, production can be carried out based on drawings and samples, solving the industry problem of insufficient compatibility of standard parts on the market.
Combining die-casting integrated molding and CNC precision-finished structure, the semi-enclosed shell with bottom mounting flange provides stronger rigidity through a double-layer support structure. After the base is placed, it is locked to the hydraulic oil tank and frame, firmly securing the pump assembly. Optimized reinforcing rib layout disperses vibration during equipment operation, preventing base cracking and screw loosening after long-term use; precise flange threaded hole positioning ensures seamless assembly without gaps or loosening, achieving efficient and stable pump-machine connection, suitable for heavy-duty hydraulic applications such as construction machinery, textile machinery, and packaging equipment.
Products adhere to the ISO9001 quality management system. Raw materials undergo spectral testing for purity upon entry into the warehouse. Each process in production is inspected, and finished products undergo full inspection using micrometers and calipers to check hole diameter, flatness, and hole spacing accuracy. Defective products are rigorously rejected.
