Major systems
Electrical system
The pump uses 3-phase alternating current (AC) electricity. Some parts, such as valve solenoids and sensors,
use 24-volt direct current (VDC) electricity from a power supply in the electrical enclosure.
End-of-travel sensing
When hydraulic fluid forces the piston to the end of the hydraulic center section, the piston pushes against a
spring-loaded indicator pin. A signal from the proximity sensor above the indicator pin causes the shift valve in the
primary hydraulic manifold to change the direction of the intensifier.
Primary motor
The primary motor drives the primary hydraulic pump that moves hydraulic fluid through the intensifier. A gear
pump moves hydraulic fluid through the cooling loop.
