The product selection from Pierburg Pump Technology covers the complete range of applications for electric water circulation and coolant pumps in the automotive industry. Pierburg has extensive experience in the area of electric water pumps, especially with regard to EC engine technology and hydraulics. The canned motor concept was selected to meet the high requirements for operational reliability and service life. This special motor design has an additional tube placed in the space between the stator and the rotor, which keeps the stator statically sealed with respect to the medium pumped by the running rotor. Since this drive system requires no dynamic sealing elements which are subject to wear (rotating mechanical seals), the water circulation and coolant pumps are especially reliable and free of wear problems. Moreover, the EC motor used in the pumps requires no brushes. Eliminating the mechanical commutation system leaves the durability of the rotor bearings as practically the only limiting factor for service life. In addition to that, the lower number of moving parts results in significantly reduced noise.

Product Features:

• OE Quality, reliability and service life
• Reduction in noise
• Leak-proof sealing of the drive
• Fuel savings and reduced emissions
• Cooling even without operation of the engine
• Water circulation pump can deliver as much as 800 liters per hour
• Coolant pump can deliver more than 9,000 liters per hour
