Instron’s hydraulic grip pumps deliver precise, reliable clamping force for high‑capacity materials testing, supporting systems up to 600 kN. The compact 2718‑700 provides up to 207 bar for wedge grips with optional Bluehill Universal integration, while the 2718‑550 supports both wedge and side‑acting grips with continuous 24/7 operation and a two‑stage flow system for faster throughput. Both models feature front‑mounted analogue gauges for easy monitoring and seamless compatibility with Instron hydraulic grip families.

Compact Hydraulic Grip Pump

Catalog Number 2718-700

The 2718-700 compact hydraulic grip pump is designed for use with Instron’s hydraulic wedge action grips ranging up to 100 kN capacity. This pump can be configured to provide between 41 bar (600 psi) and 207 bar (3000 psi) clamping pressure and incorporates two analogue pressure gauges that are easily visible to the operator from the front of the pump.

The pump can be configured to run in either Stand-Alone or Integrated mode. In Integrated mode, pressure settings are controlled in Bluehill Universal and can be defined in your methods — reducing errors and time spent manually adjusting pressure settings between different tests.

Hydraulic Grip Pump

Catalog Number 2718-550

The 2718-550 hydraulic grip pump is compatible with Instron’s hydraulic wedge and side action grips and is designed for continuous 24/7 operation for both 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 69 bar (1000 psi) to increase productivity. Once the grips clamp the specimen, the pressure will then increase to the full pressure at the slower flow rate.
