Bladder Tanks Explained


PILLOW TANKS

Flexible Pillow Tanks, which are also known as bladder tanks, have been designed to store liquids from 1,000 litres to 2,000,000 litres. Our pillow tank design has been used successfully for many years to store product over short, medium and long terms of use.

Our pillow tanks are manufactured in a technical fabric with a polyester thread and coated in PVC (Polyvinyl Chloride). The material is bonded together to make the pillow tank construction by welded the seams together using a High Frequency Welding machine.

FREQUENTLY ASKED QUESTIONS

 

WHAT GROUND PREPARATION IS NEEDED?

A flat well-drained location is the ideal choice of a site that should be free from rocks, stones, tree stumps or any other sharp objects that may chafe or puncture the tank. On rough or stony ground sharp objects should be removed and ideally a layer of sand laid to provide a base. Maximum care must be taken to avoid placing tanks on ground having a cross slope as the tank is liable to “roll away” when being filled.

DO I NEED A GROUND SHEET?

Not always, if the ground is free from debris and sharps then you can use these tanks without a ground sheet however, we do recommend using a ground sheet to prolong the life of the bladder tank

HOW DO I FILL THE TANK?

This can be done from the water mains or through a pump with the relevant connector fitted to attach to the bladder tank. This must start slowly (up to max 490 litres per minute) then increased to a maximum of 1,000 litres per minute dependent on tank capacity

HOW DO I EMPTY THE TANK?

This can be done by gravity or pumped, the tank may have to be lifted slightly to empty any remaining liquid

HOW DO I MAINTAIN THE BLADDER TANK?

Our bladder tanks are quite easy to maintain. The surface should kept clean of debris and washed down occasionally. The inside can be cleaned through a small hatch using a hose pipe then drained away

CAN THE BLADDER TANKS BE REPAIRED?

Small cuts and abrasions can be repaired using our repair kit. Larger cuts/splits may have to be repaired at our factory (for a fee)

WHAT LIQUIDS CANNOT BE STORED IN A BLADDER TANK?

PVC bladder tanks can store most liquids except fuels and certain acids, this requires a special material so please inquire. We can manufacture a bladder tank to store pretty much any liquid, but please check with us regarding your specific application
