GRUNDFOS TPE2 40-80 Grundfos TPE Series 1000, TPE2 pumps are single-stage, close-coupled in-line centrifugal pumps with mechanical shaft seal and primely for applications such as heating/cooling/district energy. The pumps are fitted with frequency controlled motors.
The TPE Series 1000, TPE2 has a close-coupled design and specially constructed shaft seal chamber, reducing sensitivity to impurities in the pumped liquid compared to canned rotor pumps. Optimal water circulation is also ensured. This explains the long lifetime of the mechanical shaft seal. Robust, reliable and low on noise, the TPE Series 1000, TPE2 is ideal for heating, cooling, air-conditioning, district energy and industrial applications. GRUNDFOS TPE2 40-80 suitable for commercial air conditioning.
