HP550SMIN Enerpac HP Series Sealed Hydraulic Hand Pump, Single Port, 10,000 psi, 35.4 in³, Two-Speed

HP550SMIN Enerpac HP Series Sealed Hand Pump is the middle single-port size in the HP range. Its 35.4 in³ usable oil capacity doubles the practical fluid reserve of the compact HP350S while remaining substantially smaller than the 67.7 in³ HP1000S.

A Mid-Size Choice for Single-Acting Hydraulic Equipment

This model is useful when the tool’s oil demand falls between the two extremes of the HP family. Matching reservoir capacity to the actual circuit helps avoid carrying a larger pump than necessary while ensuring enough fluid is available to complete the tool stroke.

Enerpac’s sealed reservoir permits operation at different angles and protects against accidental spillage and air contamination. The two-speed pump reaches 10,000 psi and comes with a gauge for system-pressure monitoring.

If the job requires a second independent connection, HP550DMIN uses the same capacity with twin ports. For classified hazardous areas, HP550SMINEX adds the corresponding ATEX certification.
