Professional Hydraulic Pump Manufacturer in China

As a professional manufacturer and supplier of hydraulic pumps in China, Hengmeisi utilizes high-strength cast iron or aluminum alloy pump bodies combined with precision-engineered sealing chambers. Driven by external power, the internal moving components periodically alter the volume of the sealed working chambers, thereby achieving a stable conversion of mechanical energy into hydraulic energy. Our optimized chamber structure and high-precision machining effectively minimize internal leakage and enhance volumetric efficiency.

Key Features

· Efficient Energy Conversion: Converts mechanical energy into hydraulic energy with minimal loss, maintaining stable flow and pressure.

· Durable Materials: Pump body made from high-strength cast iron or aluminum alloy resists pressure and corrosion.

· Precision Components: Transmission shaft and valve group engineered for smooth power delivery and accurate flow control.

· High Performance: Volumetric efficiency, flow rate, speed, and noise optimized through precise cavity design and machining.

· Standards Compliance: ISO 9001 certified and tested for pressure, leakage, and endurance before delivery.

Working Principle

Hengmeisi Hydraulic Pump operates via periodic volume changes in its sealed cavity. When the cavity expands, oil is drawn in; when it contracts, oil is pressurized and discharged. This cycle ensures continuous hydraulic energy transfer. Optimized cavity geometry and high-precision machining minimize leakage, maximize efficiency, and support stable operation across diverse industrial systems.

Core Structure

· Pump Body: High-strength cast iron or aluminum alloy ensures pressure resistance and durability.

· Transmission Shaft: Transfers mechanical energy to hydraulic flow with minimal vibration.

· Sealed Cavity: Forms the core working chamber for efficient oil intake and discharge.

· Valve Group: Maintains accurate flow direction and pressure control.

· Sealing Accessories: Prevent leakage and extend service life.
