VPN Sliding Vane Pump

Fuel & Oil Transfer for Tank Trucks

The VPN pump offers reliable and quiet operation, even in harsh operating environments. Its compact construction, low weight combined with high flow and easy maintenance make it an ideal choice for modern tank trucks, trailers, and skid-mounted systems.

High Flow Rate with Low Weight

The VPN sliding vane pump combines a high flow capacity with a compact and lightweight design, making it especially suitable for tank trucks where payload optimization is critical. Its efficient internal geometry ensures maximum throughput without adding unnecessary weight to the vehicle.

Low Maintenance with Self‑Lubricating Components

Maintenance requirements are minimized thanks to self‑lubricating carbon bushings and wear‑resistant materials. These features significantly reduce service intervals and lifecycle costs while ensuring consistent performance over time.

Easy Maintenance and Serviceability

The VPN pump is engineered for quick and easy servicing, requiring no special tools. A single mechanical shaft seal and straightforward internal layout allow maintenance tasks to be completed efficiently, helping to minimize vehicle downtime.

Robust Construction for Transport Environments

Designed for harsh operating conditions, the VPN features a rugged cast‑iron body and durable internal components. This robust construction ensures long service life even when handling demanding fuels and oils in transport applications.

Constant‑Flow Sliding Vane Technology

Thanks to its sliding vane principle, the VPN delivers a steady flow across a wide range of operating conditions. This constant‑flow behavior ensures accurate and smooth transfer of fuel and oil products, improving system efficiency and operational reliability.

Fully Self‑Priming Performance

The VPN pump is fully self‑priming, providing strong suction capability even in demanding transfer situations. This allows reliable loading and unloading operations without external priming systems, reducing system complexity and setup time in the field.

Quiet and Smooth Operation

The optimized vane design and internal lubrication result in low noise and vibration levels during operation. This makes the VPN particularly suitable for urban deliveries and applications where operator comfort and noise reduction are important.

Compact 90° Sliding Vane Design

The VPN pump features a 90° sliding vane configuration that allows for a compact installation on tank trucks and mobile systems. This layout minimizes required mounting space while maintaining excellent hydraulic performance, making the pump ideally suited for transport applications where space and weight are critical. 

Constant‑Flow, Self‑Priming Performance

The sliding vane principle provides a continuous flow and ensures reliable volumetric efficiency across the operating range. The VPN is fully self‑priming, delivering strong suction capability for fast and dependable loading and unloading operations without external priming devices. 

Flow Rate and Operating Pressure

The VPN pump is designed for high‑capacity fuel and oil transfer while maintaining safe operating pressures for transport systems.

  • Maximum flow rate: up to 1100 l/min
  • Maximum working pressure: 10 bar g
  • Differential pressure: 0 – 8 bar g
  • Maximum rotation speed: 650 rpm

Fluid Compatibility and Operating Range

The VPN is suitable for a wide range of fuels and oils used in transport applications. It handles fluids with varying viscosities and temperature ranges while maintaining stable performance.

  • Dynamic viscosity: up to 5000 cSt*
  • Fluid temperature range: –20 °C to +70 °C
  • Compatible with diesel, gasoline, kerosene, ethanol, methanol, petrol, and oil

* Depending on rotation speed

Sealing Concept and Low‑Maintenance Design

The pump is equipped with a single mechanical shaft seal designed for easy servicing and long service life. Maintenance‑free, self‑lubricating carbon bushings reduce wear and eliminate the need for frequent lubrication, significantly lowering total cost of ownership.

Integrated Bypass and Rotation Flexibility

For system protection and operational flexibility, the VPN can be supplied with an integrated mechanical or pneumatic bypass valve. The pump supports clockwise or counter‑clockwise rotation, allowing easy integration into various vehicle layouts and drive configurations. 

Drive Options and Certification

The VPN pump is compatible with multiple drive solutions commonly used in transport systems and is designed to meet safety requirements for hazardous environments.

  • Drive options: PTO, hydraulic, electric, or diesel/petrol engine
  • Certification: ATEX compliant for use in explosive atmospheres
