Bladder Tank 8L 10 bars

Bladder Tank 8L 10 bars (Reference: 302008) - Professional Multitanks solution for pressure regulation in hydraulic installations. This membrane tank is designed to optimize pump operation and maintain stable pressure in drinking water and industrial circuits.

Advantages and applications of the bladder tank

This 8-liter bladder tank is essential to reduce pump start/stop cycles, thus extending their lifespan and reducing electrical consumption. It maintains constant pressure in the network, preventing pressure surges and improving user comfort.

Perfect for domestic installations: water pressure boosting, automatic irrigation, tap supply, electric water heaters. Also suitable for professional applications: workshops, garages, agricultural installations, irrigation systems, industrial cooling circuits.

Its 8-liter capacity makes it the ideal choice for medium installations, offering a good compromise between size and autonomy. It absorbs flow variations and maintains pressure even during intermittent draws.

Technical characteristics and construction

This tank benefits from an interchangeable food-grade butyl bladder, a material recognized for its chemical resistance and compatibility with drinking water. The bladder perfectly separates water from compressed air, thus preventing tank corrosion and oxidation phenomena.

The steel vessel is anti-corrosion treated to resist the most demanding operating conditions. With a diameter of 200 mm and a height of 335 mm, this tank easily integrates into reduced spaces while offering optimal storage capacity.

The 1-inch fitting (BSP thread) ensures a secure and tight connection with standard hydraulic circuits. The maximum operating pressure of 10 bars allows use in most domestic and semi-industrial applications, with a comfortable safety margin.

Installation and commissioning

Installing this bladder tank requires vertical positioning, fitting upward, to ensure proper bladder operation. Provide sufficient space around the tank to facilitate maintenance and possible bladder replacement.

Before commissioning, check the pre-charge pressure (generally 1.5 to 2 bars for an operating pressure of 3 to 4 bars). Use a pressure gauge to control air-side pressure via the valve located on the tank.

Connect the tank between the pump and distribution circuit, preferably after the pressure switch and pressure gauge. Use quality fittings and apply appropriate sealant to threads. Perform a progressive leak test up to operating pressure.

Expert advice and maintenance

To optimize performance, properly size the tank according to pump flow rate: allow approximately 1 liter of capacity per 100W of pump power. This 8L tank is perfectly suited for 600 to 800W pumps.

Regularly check pre-charge pressure (every 6 months) as air-side pressure loss reduces system efficiency. Monitor pump cycles: overly frequent cycles may indicate a faulty bladder or incorrect pre-charge pressure.

The interchangeable bladder facilitates maintenance: in case of failure, no need to replace the entire tank. Combine this tank with our adjustable pressure switches, glycerin pressure gauges and brass fittings for a complete and professional installation. For food applications, favor stainless steel fittings from our professional range.
