Power Units

ESCO engineers developed faster hydraulic power units to improve performance and reduce cycle time on older ESCO Swagers. Two models are available:

• 4089147 for MK 75-87-100 ESCO Swagers
• 4089576 for MK 150-200-250 ESCO Swagers

The self-contained power unit stands beside the press and is controlled by an electronic foot pedal, which activates a solenoid control valve. A built-in limit switch reduces die wear and breakage, while minimizing stress on the swager. A sight-glass indicator makes it easy to monitor oil level and temperature, and an easy-to-read gauge shows when the filter needs to be changed. In addition, an hour meter is built into the electric control housing to help schedule maintenance.

Value Added Benefits

• NEMA four-code combination motor starter control box.
• Hour meter built-in to schedule maintenance.
• An electric foot pedal controls solenoid operated control valve.
• Uses Chevron IS0 32 anti-wear hydrualic oil or equivalent.
• A filter gauge indicates when filter needs service.
• Easy to replace canister filters.
• Sit gauge indicates oil level and temperature.

Included with these power units is a travel limit switch – an optional install on older ESCO Swagers. The limit switch stops the swager motion when the toggle links reach a preset angle, rather than using the mechanical stops on the older swagers. Either way, hydraulic relief valves prevent over-stressing the machine.
