ZA4440MX Enerpac ZA4 Air Hydraulic Pump is the largest-reservoir double-acting configuration in this export, with 10.3 gallons of oil capacity and a 4-way, 3-position valve.
Maximum ZA44 Reservoir Capacity
This model is intended for hydraulic systems whose cylinder displacement or overall circuit volume exceeds what the smaller ZA44 reservoirs can comfortably support. The large tank is the defining difference; valve function remains advance, hold and retract for double-acting equipment.
The air-driven Z-Class pump is rated to 10,000 psi and uses two-speed operation to reduce low-pressure travel time. Enerpac also specifies ATEX certification for the ZA4 models in this group. If 10.3 gallons is more than the system needs, ZA4420MX provides the same control concept with a 5.2-gallon reservoir.
