Single stage pipeline pump equipped with MGE motor
The Grundfos TPE 1000 series and TPE2 series pipeline circulation
pumps
The TPE 1000 and TPE2 series pumps are representatives of
intelligent vertical pipeline pumps. They feature a reliable
mechanical shaft - seal design and can adapt to various
configurations and control methods. Compared with traditional
pumps, these pipeline circulation pumps can accurately respond to
the system's pressure, temperature, and flow requirements, saving
up to 50% of power consumption. The use of an integrated frequency
converter ensures maximum efficiency around the clock.
In addition, the shaft - seal chambers of the TPE 1000 and TPE2
series pipeline circulation pumps are designed for close -
coupling, reducing their sensitivity to impurities in the pumped
liquid and ensuring the best water - circulation state. These
pipeline circulation pumps are durable, reliable, and low - noise,
making them highly suitable for heating, refrigeration, air -
conditioning, district energy, and industrial applications. They
are ideal choices for different industries.
