It stores a water supply and can deliver up to 0.5 litres of water when the pump is already switched off. It can be integrated into virtually any pressure-controlled water system (up to a maximum of 8.6 bar (125 PSI) working pressure). The balance tank ensures uniform water flow and reduces the need to switch the pump on and off. It reduces pump noise, helps save energy and extends the life of the pump. Suitable for use with PAR-MAX 2.9 - PAR-MAX 4.0. Can be mounted in any position. Connections via push-in connector, including connection adapters for 13mm (1/2") hoses: 1 x straight and 1 x 90° bend, plus 2 x adapters with 13mm (1/2") male thread.
