ZE3440SJ Enerpac Electric Hydraulic Pump, VE43 Solenoid Valve, LCD, 10.3 gal, 460V 3-Phase

The Enerpac ZE3440SJ is a ZE3-Series electric hydraulic pump set up for double-acting cylinders that need powered advance and retract with a hold position. It is built for plant and production settings with 460–480V three-phase power. ZE3 is the entry flow group of the ZE range; the ZE4, ZE5 and ZE6 deliver 60, 120 and 200 in³/min for larger or multiple cylinders.

Sizing

As a two-stage pump, the ZE3440SJ delivers about 450 in³/min at 100 psi and 385 in³/min at 700 psi, so cylinders move quickly to the load, then drops to 40 in³/min at 10,000 psi. Moving 100 in³ of oil under full load takes about 150 seconds. The 10.3 gal reservoir holds 2,379 in³ of usable oil; keep the combined oil capacity of all connected cylinders comfortably below that figure. Flow figures are at 60 Hz; on 50 Hz power expect about 5/6 of these values.

How it compares

The ZE3420SJ is the same configuration with a 5.2 gal reservoir instead of 10.3 gal. For more flow in the same configuration, the ZE4440SJ delivers 60 in³/min at 10,000 psi.

Before you order: Confirm a 460–480V three-phase supply at the point of use; check total cylinder oil volume against the 2,379 in³ of usable oil.
