SPump Family

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

Spheros has become leading manufacturer of high-end water pumps for bus and truck, agricultural and construction machinery, off-highway and commercial vehicles.

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 SPump S120 and S200 are the lightest weight and most compact circulation pumps of their kind within the product family. The 500 W variant convinces with a high flow rate at high counter pressure. 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 in comfort application and component cooling worldwide.

Highlights

Low life-cycle costs

  • Leak-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
  • With the IP6k9k classification, the pump is dust and waterproof - ideal for demanding environmental conditions and other applications

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 versions
  • Increased operational safety and comfort while reducing operating costs

Reliability & durability

  • The extended temperature up to +95°C allows operation under hot ambient conditions in the bus
  • Full Protection Package in CAN versions
  • High EMC level

Comfort

  • Intelligent function - Error diagnosis and function monitoring of CAN versions
