MGE motors - Grundfos

The motors incorporate a PI controller. You can connect the motors to a signal from an external sensor and a setpoint signal enabling control in closed loop. You can also use the motors for an open-loop system in which the setpoint signal is used as a speed control signal. The motors incorporate an operating panel which is available in various ...

Mechanical shaft seals for pumps

The shaft seal forms a barrier between what is inside the pump and the atmosphere. A pump with a through-shaft is not completely sealed. It is a challenge to the entire pump industry to minimise leakage. There are countless variants of shaft seals, reflecting the diversity of …

In domestic hot water systems, the temperature of the pumped liquid must always be above 122 °F (50 °C) due to the risk of legionella. The temperature of the hot water source must not be high enough to cause burns or scalding.

Three Phase Power Supply Unbalance For three phase systems a true full 3-Phase Delta {3 pot system} transformer setup is recommended or one true 3 phase transformer. This system, although much better than an open delta 2 pot system, still does not guarantee good balanced power. Load unbalance can still occur on this

If the pump is installed above the liquid level, a non-return valve must be fitted in the inlet pipe below the liquid level. See fig. 4. Self-priming pumps We recommend an opening pressure of the non-return valve which is lower than 0.05 bar. Otherwise, the additional resistance will reduce the suction capability of the pump.
