2718-550 | Hydraulic Grip Pump

The Instron 2718-550 hydraulic grip pump is designed for continuous 24/7 operation in manual and automated testing systems in industrial environments.

It can be configured to provide a maximum pressure of 207 bar (3000 PSI for use with wedge grips), or alternatively 138 bar (1900 PSI) for use with side acting grips. The unit incorporates two analogue pressure gauges, that are easily visible to the operator from the front of the pump.

The 2718-550 pump is configured to operate with a two stage flow speed, with a higher flow rate up to 69bar (1000psi) to increase productivity. Once clamping the specimen the pressure will then increase to the full pressure at the slower flow rate.

Principle of Operation

The 2718-550 hydraulic grip pump is activated by a footswitch, while a handset provides close/open functionality of each grip independently. The gripping pressure is easily configured by an electrical adjustment knob located on the front of the pump.

Features and Benefits

  • Dual Stage gripping pressure - improving operator safety & preventing specimen damage while reducing closing time
  • Easy to use grip control handset
