SPump Family

Electric water pumps for buses with hybrid, plugin, electro or diesel engine

Valeo‘s well-known SPump range has expanded. New versions with PWM and CAN feature variable speed control, save energy, reduce noise emission and always provide outstanding performance required for electrically powered vehicles.

The newly introduced SPump S120 is the lightest weight and most compact circulation pump of its kind within the product family. It saves space and is particularly suitable for smaller water circuits. Whereas another 500W variant convinces with a flow rate of more than 10,000 l/h.

With an extended ambient temperature range of up to 95°C at the highest level of reliability, the SPump is the best solution for water pumps worldwide.

Highlights

Low life-cycle costs

  • Leakage free, wear resistant and maintenance free due to the magnetic drive
  • Brushless EC-motor allows a long service lifetime of up to 40,000 h
  • Due to the IP6k9k classification, the pump is dust and waterproof - ideal for heavily salted winter roads and other demanding applications
  • Best efficiency point for SPump S120: Flow rate of 4,000 l/h @ 0,35 bar
  • Best efficiency point for SPump 260: Flow rate of 5,500 l/h @ 0.6 bar
  • Best efficiency point for SPump 500: Flow rate of 6,500 l/h @ 1.15 bar

Environmentally friendly

  • Noise-optimized and ideally suited for use in electric or hybrid buses
  • Optimized power consumption, high efficiency and energy savings through variable speed control in the PWM & CAN SPump versions
  • Increased operational safety and comfort while reducing operating costs

Reliability & durability

  • The extended temperature range from -40°C up to +95°C (SPump 500 CAN Tmax= +85°C) allows installation under hot ambient conditions in the bus
  • Full Protection Package - extensive self-protection and diagnosis
  • High EMC level

Comfort

  • Available communication interfaces: ON/OFF, PWM and CAN
  • Intelligent function - Error diagnosis and function monitoring of CAN versions
