Additional products

Professional water intake installations, based on GT deep-well pumps should be equipped in a hydrophore tank and a pressure switch. Thank to this solution when the pressure in the tank falls to the set minimum the pump automatically switches on and turns off when the pressure in the tank is at level of the set maximum. This reduces the amount of pump activations (each turn on of the tap doesn’t cause the pump to activate – the water supply from the tank is used) and at the same time it protects the pump from wearing down too quickly. The tank accumulates a reserve of water equaling to around 1/3 of its capacity, which also gives the user the comfort of an access to water in the event of temporary electrical supply outage.

With the use of deep –well GT pumps we recommend the use of HVP (galvanized) and ZBOS/ZBOL (with a rubber membrane) hydrophore tanks, LCA pressure switch and LCS protection against dry running, which make up elements of properly working water supply machines.

The wells are drilled in places where the water surface occurs in depth not bigger than app. 8m and also wells dug at similar level of the water surface allow the usage of extremely resistant, strong and characterizing in a very long lifetime surface and self-priming pumps SKA, SKB, SM type produced by Hydro-Vacuum S.A. and based on them water supply machines.
