Vickers Type VTM42 Series High-Performance Power Steering Pumps

Product Overview: The VTM42 Series vane-type steering pump is the definitive power source for commercial vehicles and heavy-duty machinery steering systems. Engineered as a highly integrated steering solution, the VTM42 features an integral flow control valve and pressure relief valve within its compact housing, providing stable power assist without the need for external valve manifolds. This range features industry-standard models including VTM42-40-30-15-NO-RI-14, VTM42-50-30-12F07-R1-15, and VTM42-40-30-15NO-R1-14. With its superior balanced vane design, the VTM42 series delivers smooth, quiet, and rapid-response performance even under extreme steering loads.

Key Technical Advantages:

• Fully Integrated Functionality: Built-in pressure control and flow regulation mechanisms reduce external plumbing connections, significantly lowering leak risks and optimizing installation space.

• Superior Low-Speed Performance: Optimized vane geometry ensures ample steering pressure output even at engine idle speeds, enhancing driving safety and maneuverability.

• Extended Service Life: Utilizes a pressure-balanced rotor group to eliminate side loading on bearings, ensuring exceptional durability through frequent, high-angle steering cycles.

• Silent & Smooth Output: Precision-ground stator curves effectively suppress fluid pulsations, eliminating “humming” noises during steering to improve cabin comfort.

• Target Applications: Heavy-duty trucks, city transit buses, agricultural tractors, construction equipment, and power steering systems for specialized mobile machinery.
