Grundfos TPE Series 1000, TPE2 adapts to all needs
TPE Series 1000, TPE2 is an intelligent, vertical in-line pump that smoothly adapts to signals from an external sensor. Regardless of the configuration or control method in use, you can count on a precise response to your system’s pressure, temperature and flow rate needs – with up to 50 % less energy consumption compared to a conventional pump. Key features include an integrated frequency converter, which ensures maximum efficiency around the clock.
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.
How can a blockage in a heating/wet-running pump be overcome?
De-energise the pump. Remove the screw in the centre of the nameplate. The shaft located beneath this has a groove. Place a screwdriver in the groove and move the shaft in the direction of rotation until you have removed the blockage.
Modern self-regulating heating pumps no longer have a screw in the centre of the nameplate. However, modern pumps have an anti-block feature. Should a blockage nevertheless occur, the pump head must be removed.
