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.
