Press Pac® 3200 Series Benefits
Superior Heat Dissipation
Increased thermal capacity allows for more strokes per minute, more parts per hour and a substantial cost savings can easily be realized. Unit offers high cooling capacity through the advanced circulating oil system that dissipates and cools the oil. Friction discs are continually lubricated offering excellent single stroke rate performance due advanced oil shear design.
Longer Clutch/Brake Life
The advanced circulating oil system delivers cool oil to lubricate friction discs. Oil shear technology, the viscous shearing of oil between alternating discs, transfers torque and drive inertia resulting in less wear on the friction disc surfaces.
Maintenance Free
Press Pac® provides millions of strokes with little to no maintenance or repair requirements and thus, will lower your annual maintenance cost.
Smooth, Quiet Engagement
Noise free, cushioned engagement of oil shear technology decreases gear train wear and extends the life of press parts.
Excellent Start / Stop Capability
Precise, repeatable clutch engagement and improved stopping times are easily achieved through simple set up and adjustments in the control system. Reduced stopping times can provide faster press cycle times and improve machine productivity.
Reduced Life Cycle Costs
Achieve up to 10 years of high volume production without any press downtime or costly repairs. Press Pac®, when compared to standard dry friction clutch/brakes, eliminates costly downtime to replace damaged parts, packings and worn out brake linings and presents a substantial cost savings of the life of your machine.
