7500 psi max
Single Acting
FEATURES: Screw Clamps are an ideal hydraulic pressure source for small clamping fixtures that must be independent of an external power source. Small enough to mount directly on the fixture. Can be operated manually with a crank handle or using a power torque wrench (non-impact type). Produces 7500 psi hydraulic pressure from only 40 ft-lbs torque. Can be used in multiples if greater fluid capacity is required. The block type shown here allows convenient mounting when using exposed fluid lines.
OPERATION: Turn screw shaft clockwise to clamp. Tighten until desired pressure is reached (read pressure on a separate gauge, or tighten to a predetermined torque). Turn counterclockwise to unclamp.
MOUNTING & SETUP: Mount horizontally with fluid fill port up. Fasten with two cap screws. Fill system with clean, approved Hydraulic Fluid with the pump piston fully returned. System must be totally purged of air. Do not use NPT fittings.
DESIGN CONSIDERATIONS: In closed systems such as this, all clamps and components must be leak-free, so use only SWIFTSURE products. For best results, clamps should use only 60-70% of the Screw Pump's total fluid capacity. System plumbing must be designed to avoid air pockets. If Screw Pump is not at the highest point in the system, include a separate fill plug at the highest point. Always include a pressure gauge on the fixture when using a Screw Pump. When using an accumulator, use only the smallest size (CLR-9606-102-PDA) due to limited fluid capacity. For additional safety on palletized fixtures, use a Control Cylinder, with position sensing on the machine tool. |
