Engine cooling

Water pumps - cooling for a long engine life

The water pump is the central component in the coolant circuit. Mechanical water pumps are a well-established solution.

The electrically driven coolant pumps provide demand-based engine cooling, reduce power requirements and cut frictional losses, fuel consumption and pollutant emissions.

Pierburg production sites produce more than seven million mechanical and electrical water pumps for motor vehicles and utility vehicles every year.

Mechanical water pump

The cooling liquid of the water pump absorbs the heat from the engine block and cylinder head and releases it into the ambient air through the cooler. Depending on their design, mechanical water pumps are located either externally on the engine in their own pump housing or are flanged directly on the crankcase and are driven by a V-belt, toothed belt or the engine directly.

Quality features of our water pumps:

  • High-quality sliding ring sealing cartridge
  • Maintenance-free, long-life rolling bearings
  • Flow-optimised impellers made from plastic, steel, aluminium or brass
  • Gaskets and O-rings are included in the scope of supply

Electrical water pump

Electrical water pumps make a significant contribution to emission control on modern engine designs.

A delivery rate that is not dependent on the engine speed enables demand-based cooling. This reduces the power requirements whilst also cutting down on frictional loss, fuel consumption and pollutant emissions.

Pierburg has made this technology ready for series production and is the world’s first series-production supplier of electrical water pumps.

Water circulating pump

Water circulating pumps are used where cooling or heating functions need to be performed independently of the coolant circuit. In independent heating systems,
water circulating pumps are used for quickly heating the passenger compartment, for example.

Ever since they were launched on the market in 1996, more than 50 million water circulating pumps have been produced in Pierburg’s plants.
