Davey Supercell Steel Pressure Tanks with Captive Diaphragm (8 - 200 Litres)

The Davey Supercell Pressure Tank range is built tough to provide reliable water storage under pressure, helping you get the best performance from your water system. Designed with a captive diaphragm, these tanks act as an energy-saving buffer, reducing pump cycling and extending pump life by eliminating the need for your pump to start every time a tap is turned on.

Manufactured with a deep-drawn steel shell and finished with epoxy primer and a two-part polyurethane enamel, Supercell tanks are protected against rusting and UV damage for long service life. Inside, an FDA-approved butyl rubber diaphragm and virgin polypropylene liner keep stored water safe, clean, and separate from the tank walls. The patented stainless steel water inlet (200L excluded) ensures a complete, leak-free seal even in tough water conditions.

Every Supercell tank is individually pressure-tested and certified to international standards, giving you peace of mind that your water system will run smoothly and reliably for years.
