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.
TPE2 100 - 180 N - A - F - A - BQQE - IWB
A close - coupled single - stage volute pump with coaxial suction and discharge ports of the same diameter. The water pump has a pull - out design. For example, the power head (motor, pump head, and impeller) can be removed for maintenance while the pump casing remains connected to the pipeline. The shaft seal complies with the DIN EN 12756 standard. The pipeline connection is achieved through PN 16 DIN flanges (EN 1092 - 2 and ISO 7005 - 2 standards). An air - cooled permanent - magnet synchronous motor is installed on the water pump. According to the IEC 60034 - 30 - 2 standard, the energy efficiency of this motor is at the IE5 level. |
