VTM42 & VTM42A Power Steering Pump | VTM42-10, 20, 40, 50, 60 | Vickers Type

VTM42 & VTM42A Series High-Performance Power Steering Pumps

Product Overview: The VTM42 and VTM42A Series serve as the global standard for heavy-duty vehicle power steering systems. As high-performance balanced vane pumps, these series feature an integrated flow control valve and pressure relief valve within the pump body, ensuring a constant and safe power supply for the steering circuit across varying engine speeds. This range features the full specification matrix from 1.0 GPM up to 6.0 GPM, including core models VTM42-10, VTM42-40, and VTM42A-20. With their compact design and superior durability, the VTM42 series effectively reduces steering effort and significantly enhances overall vehicle handling safety.

Key Technical Advantages:

• Integrated Flow Control: The built-in flow compensation mechanism ensures precise steering at high speeds and effortless maneuvering at low speeds.

• Dual Pressure Safety Protection: Equipped with a preset relief valve to protect the steering gear from instantaneous high-pressure damage, reducing system maintenance costs.

• Balanced Vane Technology: Features the classic Vickers-type balanced vane design, which drastically minimizes bearing loads and ensures an extended service life even at pressures exceeding 1500 PSI.

• Quiet Operation: Optimized internal flow paths reduce fluid pulsation, meeting stringent cabin noise standards for commercial vehicles.

• Target Applications: Heavy-duty trucks, intercity buses, material handling machinery, airport ground support equipment, and agricultural tractor steering systems.
