Overview
Hydropneumatic pressure tanks are essential for any commercial water distribution system. The internal EPDM rubber bladder separates compressed air from water — as water is drawn from the tank, air pressure pushes it out at consistent pressure. This eliminates pump short-cycling (the rapid on/off switching that destroys motors), dampens pressure spikes from sudden valve closures, and provides a buffer of pressurized water for immediate demand. Without a pressure tank, pumps would cycle on/off every few seconds during variable demand — leading to premature motor failure and inconsistent water pressure. For commercial laundry operations, consistent water pressure directly impacts wash quality.

Frequently Asked Questions
Why does my booster system need a bladder tank?
The pre-charged bladder absorbs pressure fluctuations and stores a buffer of pressurized water, so your pumps cycle far less often. Fewer starts per hour means dramatically longer pump and motor life, lower energy use, and steadier water pressure at the fixtures. It is the cheapest insurance in the whole pump room.
Is the bladder safe for drinking water?
Yes. The inner bladder is food-grade EPDM, which fully isolates the stored water from the steel tank shell. The water only ever touches the EPDM membrane, making it suitable for potable water systems.
How do I size the bladder tank to my pumps?
Pairing follows pump class: a 5.5 kW class duplex booster typically takes a 500 L tank, an 11 kW class takes 1,000 L, and industrial triplex systems take 2,000 L and up. If you tell us your pump configuration (or buy the system as a bundle), we size it for you as part of the quotation.
What certifications come with the tank?
The tanks carry CE marking and are manufactured in accordance with the PED 2014/68/EU pressure equipment directive, with ASME-rated construction available for commercial and industrial applications. Because this is a pressure vessel, the paperwork matters as much as the steel: every shipment includes material test certificates for the shell and factory inspection reports confirming the tank passed pressure testing before dispatch. The food-grade EPDM bladder is documented as well, which supports potable water compliance if your project requires it. Consultants and building officials sometimes ask for specific certificate formats for pressure vessel registration or permit submittals, so raise this requirement early at the inquiry stage: the exact document package for your order is confirmed in the written quotation, and we respond to every inquiry within 1 business day so your submittal schedule is not left waiting.
What is the lead time for bladder tanks?
Smaller tanks of 100 L to 300 L run 14 to 28 days from down payment, mid-size tanks of 500 L to 1,000 L run 21 to 35 days, and 2,000 L industrial units run 30 to 45 days. Custom capacities of 5,000 L and above run 45 to 75 days because the shell and bladder are built to order rather than pulled from a standard line. These timelines include factory pressure testing and inspection, and the corresponding test reports ship together with the tank. Since bladder tanks are almost always ordered as part of a booster pump bundle, the practical schedule usually follows the pump system lead time, and we align the component deliveries so everything arrives on site together. The committed lead time for your exact tank configuration is always stated in the written quotation.
Do you install the tank or just deliver it?
Both options are available and quoted separately on the same quotation so you can compare the numbers directly. Supply-only means the tank is delivered to site with its documents while your contractor handles positioning, piping tie-in, and pre-charge adjustment, which suits projects where an MEP contractor is already mobilized. Supply-plus-installation means our team positions the tank, connects it to your pump system, sets the pre-charge pressure to match your pump cut-in settings, and verifies operation before handover. The pre-charge setting is the detail most often done wrong in self-installs (an incorrectly charged tank protects nothing), so if your team has not commissioned a bladder tank before, the installed option is worth the difference. Tell us which scope you prefer when you inquire and the quotation will show both figures within 3 to 5 business days.
