HYDROTUBE TANKS U/S 50 R

The tank is made of stainless steel and has a capacity of 50 liters. The assembly includes a Hydrotube pressure water tank, pressure switch, pressure gauge, check valve, shut-off valve, plastic pipe connector, flexible steel hose, and necessary fittings. The Hydrotube pressure water tank is a steel tank in which water is enclosed in an EPDM rubber bladder pressurized with air. The rubber bladder is made of high-quality, potable water-compatible EPDM rubber. The bladder is removable for cleaning or replacement by detaching the connection cap. The precharge pressure is adjustable between 1 and 5 bar. The pressure can be increased or decreased as needed via the air valve. However, the general rule is that the precharge pressure should be 0.2 bar higher than the pump’s activation pressure. Operation

When water is pumped into the bladder, it expands due to the water pressure. Simultaneously, the air between the tank and the bladder is compressed until the cut-off pressure is reached. Both the activation and cut-off pressures are set via the pressure switch. The pump restarts when the activation pressure is reached during water draw-off. Air does not escape with the water, as typically occurs in conventional pressure tanks. In the Hydrotube, the water remains always fresh, and nearly all the water in the tank is replaced before the pump restarts.

A compact tank suitable for even small spaces. It can be installed in any position and connected to most pump types. The usable water volume is two to three times greater compared to a conventional pressure tank. The usable water volume remains constant due to the adjustable precharge pressure (1-5 bar) and the flexible rubber bladder.

The rubber bladder in the pressure tank is easy to maintain or replace. The tank does not “sweat” because the water does not come into contact with the outer shell thanks to the rubber bladder. No rust precipitation occurs in the water because the water is not exposed to atmospheric oxygen. Tanks can be connected in series to create a larger water reservoir.
