Grundfos TPE, TPED Variable Speed Pump Accessories Fittings Kit
£93.00 (Ex VAT)
Description
-
For twin head pumps, two transducers will normally need to be fitted. This fitting kit will provide the necessary additional plumbing connections. The above comprises 2 Tees and 2 Hexagon nipples. Note: Pressure Transducers are used for ‘feedback’ information and to ensure automatic speed control on all TPE/TPED models (TPE 2000 models have a pre-fitted transducer). For closed loop heating and chilled water systems, ‘different pressure transmitters’ are more commonly used to attain the most accurate ‘feedback’. Where the pump developed pressure is equal to or greater than the ‘system pressure’ then single point pressure transmitters can be successfully used. The pressure at the pump suction should remain stable during all flow conditions in the system. Suggested transducer sizes are referenced against each TPE/TPED model. When selecting and Different Pressure Transducer please use the suggested size. If selecting a Single Point Transducer, refer to the pump curve and then add the system operating pressure to the closed valve pressure on the pump curve for the appropriate size.
