Key Technical Advantages

• High-Pressure Wafer Design: The VMQ features a unique three-plate “wafer” design that balances the hydraulic forces on the vane tips. This minimizes internal leakage and ensures maximum volumetric efficiency even at peak 210 bar operation.

• Ultra-Quiet Operation: Engineered with optimized internal fluid paths, VMQ pumps generate significantly lower decibel levels than comparable piston or gear pumps, making them ideal for noise-sensitive industrial environments.

• Bimetallic Bushing Technology: The cartridge utilizes premium bimetallic wear surfaces, providing superior resistance to particulate contamination and ensuring excellent self-lubrication during cold starts.

• Modular Cartridge Design: The replaceable cartridge kit allows for rapid field servicing. You can restore full pump performance by simply replacing the internal core without disconnecting the entire pump housing from the circuit.

Application Areas

• Mobile Equipment: Soil compactors, large forklifts, and asphalt pavers.

• Industrial Manufacturing: Injection molding machines, die-casting equipment, and press machines.

• Material Processing: Scrap metal shears and recycling balers.

Expert Maintenance Tips

• Viscosity Control: To ensure optimal performance, maintain hydraulic fluid viscosity between 25-50 cSt at operating temperatures. Low viscosity can increase internal bypass and heat generation.

• Inlet Pressure Monitoring: Ensure the inlet vacuum does not exceed 0.2 bar. Any air ingress in the suction line will lead to cavitation, causing catastrophic pitting on the cam ring and vanes.

• Pre-Start Priming: Always fill the pump housing with clean hydraulic fluid through the outlet port before the first start-up. Dry running for even a few seconds can lead to localized welding and failure of the rotor-vane interface.
