Veljan Drive Train Vane Pumps are engineered for heavy-duty applications requiring multiple power take-offs from a single prime mover. Utilizing the high-performance fixed displacement pin vane design, these units allow for the seamless mounting of additional pumps in a tandem or series configuration. Capable of handling operating pressures up to 4650 psi (320 bar), the drive train series provides a robust and compact solution for complex hydraulic circuits. Whether driven by fixed or variable speed motors, these pumps deliver an exceptional power-to-weight ratio, enabling high-flow capacities across "B" through "E" cam ring sizes (15 to 85 gpm) while maintaining a small installation footprint.

Designed for maximum uptime, the drive train series features a rigid bearing arrangement and hydraulic pressure compensation that ensure an outstanding operational life even under heavy loads. The double-lip vane design offers superior resistance to particle contamination, while dry-lubricant-coated cam rings provide excellent cold-start capabilities. With a typical volumetric and mechanical efficiency of 94%, these pumps minimize heat generation and energy consumption. This high efficiency allows for stable operation at low speeds and high pressures, increasing overall system productivity and reducing the risk of seizure in demanding industrial or mobile environments.
