ATP expansion vessels are the ideal solution for
irrigation pumps, centrifugal pumps, submersible
pumps, and booster systems. The advanced membrane design provides higher effective water capacity that reduces pump start cycles, improves efficiency, and helps save energy. A wide range of capacities are available, including
both vertical and horizontal models. ATP expansion
vessels are equipped with galvanized steel flanges
and EPDM membranes.
Altatecks’s EPDM membrane is suitable for potable
water applications. Being securely fixed at both ends
the membrane prevents contact with the internal
tank walls that minimizes wear. The membrane is also
easily replaceable, ensuring long service life and
reliable operation.
