FOAM BLADDER TANK

Bladder tanks are the main component in a balanced pressure proportioning bladder tank system, which require no external power source other than an adequate water supply. Bladder tank is a carbon steel pressure vessel with a nylon reinforced neoprene rubber bladder that stores the foam concentrate. During operation the foam concentrate is discharged from the tank by the water supply, collapsing the bladder around the perforated center tube until the concentrate is depleted. MARSOL bladder tanks are available in both vertical and horizontal versions in multiple sizes.

Vertical bladder tanks are manufactured in accordance with ASME Code Section VIII Division 1 with a designed working pressure of 175psi (12bar) and tested to 263psi (18bar). The tank is constructed of SA 516 Grade 70 carbon steel. and UL Listed. Vertical bladder tank construction shall be mounted on a full skirt with four tabs drilled for anchoring. Tank exterior is red enamel coated. For marine and offshore application, the tanks are internally coal tar epoxy coated. Tanks are available in standard and in pre-piped configuration. Tanks are supplied with level gauge, foam concentrate control valves. Based on project requirement hydraulic operated concentrate control valves can be supplied.
