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

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 …

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.

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.

UPS2 has three proportional-pressure curves which are close to the best efficiency point. As the pump is the obvious UPS replacement option, the three fixed speeds are under normal conditions the best choice from a user’s point of view. The pump has the following control modes: • proportional-pressure control • constant-curve control.
