ZA4420MX Enerpac ZA4 Air Hydraulic Pump moves into the larger-reservoir end of the double-acting ZA4 family. Its 5.2-gallon oil capacity is twice the 2.6-gallon ZA4410MX and supports hydraulic circuits with greater total fluid demand.
More Oil for Larger Double-Acting Circuits
A 4-way, 3-position valve provides powered advance, hold and retract. That makes the model appropriate for double-acting cylinders that must be driven both forward and back rather than relying on a spring or load return.
Enerpac lists 80 in³/min at 10,000 psi for the ZA4 high-pressure stage. ZA4420MX is the practical step before the 10.3-gallon ZA4440MX when reservoir capacity—not a different valve function—is what the application needs.
