HP550DMINEX Enerpac HP Series Sealed Hydraulic Hand Pump, Twin Port, 10,000 psi, 35.4 in³, Two-Speed, ATEX Certified

HP550DMINEX Enerpac HP Series Sealed Hand Pump is the mid-capacity ATEX twin-port model. It provides two single-acting hydraulic outlets and 35.4 in³ of usable oil, making it a balanced choice when both circuit flexibility and hazardous-area certification are required.

ATEX Twin-Port Pump with More Oil Than HP350D

Compared with HP350DMINEX, this model gives the connected equipment nearly twice the usable oil capacity. That matters when two tools or circuits together would push the smaller pump close to its reservoir limit.

Enerpac’s sealed HP reservoir can be operated at different orientations while resisting accidental oil loss and air contamination. The two-speed mechanism reaches 10,000 psi, and a gauge is included for monitoring pressure at the pump.

HP550DMINEX is not simply a larger single-port pump: the twin outlets are its defining functional difference. For one circuit, HP550SMINEX is the simpler ATEX configuration.
