2. Core characteristics
High voltage and low noise design
Low-noise operation in the full pressure zone, suitable for industrial environments with strict noise requirements.
Optimize the stiffness of the pump body, reduce resonance, and adopt low-noise bearings and seals.
Modular structure
It is easy to maintain and can quickly replace key components (such as blades and stators).
The overall drive components of the pump are combined in the form of a complete set, which is easy to repair.
Wear-resistant and durable
The surface of the key components (stator, blade) is treated with manganese phosphate film, and the life of the shaft seal group reaches more than 8,000 hours.
The pump body is made of high-strength cast iron (FC250), the blades are made of high-speed steel (HSS) or tungsten carbide coating, and the shaft is made of high-carbon chromium bearing steel (SUJ2).
Pressure stability
It provides a stable pressure output for the hydraulic system and is suitable for precision control systems.
The volumetric efficiency is ≥90%, and the mechanical efficiency is ≥92%, which reduces internal leakage and friction loss.

3. Typical application scenarios
Injection molding machine
PV2R4-237 provides high-pressure power for large injection molding machines to ensure that plastics fill molds quickly.
It is suitable for the injection stage where instantaneous large flow is required to improve the quality of castings.
Die casting machine
Provide instantaneous large flow during the injection stage to improve the quality of castings.
It is adapted to the hydraulic system of the die-casting machine to meet the needs of high pressure and large flow.
Construction machinery
Drive the hydraulic cylinder to achieve precise control of the excavator arm.
It is suitable for hydraulic systems of cranes, concrete pumps and other equipment.
Other industrial fields
Metallurgical industry: hydraulic action control of blast furnaces, rolling mills and other equipment.
Shipbuilding industry: hydraulic power support for steering gear, anchor gear and other equipment.
Petrochemical industry: the hydraulic power source of fluid conveying equipment.
