Vickers Type VTM27 & VTM42 Power Steering Pump | VTM42-50, VTM27-40 | Integral Valve

Vickers Type VTM27 & VTM42 High-Performance Power Steering Vane Pumps

Product Overview: The VTM27 and VTM42 Series are the definitive “hearts” of heavy-duty vehicle steering systems globally. Engineered as balanced fixed-displacement vane pumps specifically for power steering, these units integrate both flow control and pressure relief valves within a single housing. This page highlights premium specifications, including VTM27-40-20-15-ME-L1-14-S4 and the high-flow VTM42-50-40-20. With superior shock resistance and long-term stability, the VTM series ensures precise, effortless steering control for heavy equipment under the most extreme road conditions.

Key Technical Advantages:

• Highly Integrated Design: Features integral flow control and relief valves. This compact solution saves installation space, reduces potential leakage points, and enhances the overall responsiveness of the steering system.

• Extreme Silence & Balanced Construction: The pressure-balanced design eliminates radial loads, ensuring ultra-low noise levels even at high rotational speeds while extending bearing life.

• Durability & Reliability: Constructed with high-strength cast iron housings and precision-hardened internal components, it is built to withstand mechanical shocks from frequent start-stop cycles and high-intensity steering manuevers.

• Versatile Configurations: Available with multiple flow settings (e.g., 15 GPM, 20 GPM) and various manifold/tank mounting options (e.g., S4 specifications), providing flexibility for diverse power steering requirements.

• Target Applications: Heavy-duty freight trucks, transit buses, off-road vehicles, construction machinery, and industrial vehicle power steering assemblies.
