Hyjet HPT Series

Hyjet diaphragm pressure tanks are ideally suited for a wide range of general applications including pump booster systems, thermal expansion, irrigation systems and to limit water hammer.

• Single diaphragm design 100% potable quality butyl.
• Patented 316 stainless steel connection.
• Virgin polypropylene liner, so no water touches plain steel.
• Internal clench ring becomes more secure at higher pressures.
• High-quality two-part polyurethane, epoxy primed paint finish – Almond.
• Brass stemmed air valve and O–ring sealed valve cap.
• NSF standard 61, CE / PED, WRAS approvals.
• Maximum temperature up to 90°C.
• Standard maximum pressure 150 PSI / 10 Bar.

For Pressure Switch Controlled Pumps with a traditional pressure differential of up to 140kPa (20psi), pre-charge to be 20kPa (3psi) below cut-in pressure. Once the pre-charge is set, no regular air charge checks are required.

For pumps controlled by either pressure switches with a differential over 140kPa (20psi), Electronic Controllers or VFD (Variable Speed Drive) the pressure should be set at 65% of the maximum system pressure. Once the pre-charge is set, no regular air charge checks are required.
