Kurt offers two pump types with variations on each design
Kurt KHP3 pumps are our best-selling air-over-hydraulic models, operate with shop air and can be configured as single- or double-acting and run from one vise or multiple vises on a single pump. Pumps operate semi-automated with an operator controlling the pump using a foot switch (KHP3F), hand switch (KHP3H) or a toggle (KHP3T). KHP3 pumps can also be configured to run fully automated using a machine tool controller, robot or PLC.
Kurt KHP5000 pumps are fully hydraulic and offer both dump and demand options and run with standard wall voltage. KHP5000 pumps can be configured to run one vise or multiple vises on a single pump and set up to be run semi-automated by a machine operator or fully automated with a robot, MTC or PLC.
Dump Pump: (KHP5000) Generally used where the fixture is to be disconnected from the pump for cycling. Most commonly used with a “pallet” valve. Run the pump with the foot valve until clamped and then close the pallet valve and release the foot valve.
Demand Pump: (KHP5000BP) Used where the fixture will stay connected to the pump during the cycle. If the pump loses approximately 200 PSI of pressure then it will start back up on its own to bring up the pressure to the set level. Move the lever forward to pressure up and clamp. Pull the lever back to release the pressure.
Build your own hydraulic automation
You can build a turn-key, single-acting hydraulic workholding system with a Kurt hydraulic vise, Kurt Tuff hose to connect everything and a Kurt KHP3 pump. With a few additional parts, systems can include multiple vises and full automation.
