Hello Guys,

Does anybody know why the RobotMarketPlace is showing the NPC-T64's as discontinued? We have tried to conact them and had no reply.
We contacted NPC directly to place an order after seeing this, but were told for international orders to use the robot market place.
Since this is our only supplier for these and they are showing discontinued, we have decided to go for the T74's in case we need more in the future.

We have managed to find an all in one 24v hydraulic unit from Flowfit. They have been very helpful and have work with us and helped us figure out exactly what we need in terms of valves, gauges etc.
Mini 130 Hydraulic Power Unit

  • 24Vdc 2.2kW motor c/w start solenoid
  • 2.7cc/rev pump
  • Pressure line check valve
  • Pressure line relief valve set to 200 bar
  • Cetop 2 interface fitted with 4 way 2 pos P to A & B to T then crossover directional valve 24Vdc
  • 2 litre plastic reservoir
  • 5 L/min @ 200bar

We are using it to run a 75mm, 200stroke cylinder which should give 8 tonnes. All of the components are rated to 240bar (apart from the pressure relief) so there may be scope to over-volt the motor and get more from the pump.

This is our electric circuit so far

In terms of the shot bolt, we did think about using a small hydraulic cylinder, but did not want to complicate the hydraulic system, so are now looking at an electric actuator.

This will not have to take any forces directly, as we can use it to drive a shot bolt.
