The Kinitics Piston Pump (KPP) is a shape memory alloy-based actuator that uses Bundled Wire technology to deliver a precision stroke in a compact package. Displacement and flow control is possible through the addition of a linear sensor while pressure control is possible through the use of a pressure sensor.

Kinitics Piston Pump Features

  • Wide range of compatible fluids
  • Rated pressures up to 100 Bar (1450 psi)
  • Strokes up to 7 mm (0.26″)
  • Displacements up to 8.4 cc (0.5 cu.in.)
  • Flow rates up to 25 LPH (6.6 GPH)
  • Configurable ports
  • Flexible AC and DC power options
  • Flying lead or SJOOW cable hook-up
  • -40⁰ C to 60⁰ C operating range
  • Rod and piston are the only moving parts
  • IP67 Environmental Protection
  • Compatible with ISO 21287 hardware

Accessory Add-ons

  • Wide range of mounting brackets
  • Adjustable home position switch

Potential Applications

Product Selection Chart: This chart can be used to configure the Kinitics Piston Pump.

Step 1: Use pressure and volumetric displacement to find the intersection point.

Step 2: Drawing a line horizontally to the right axis will identify the piston bore size and travel modifier.

Step 3: The shaded box that the point lands in, identified in the legend, is used to determine the nominal stroke of the KPP.  For example, if you require a precision pump with 2.5 cc displacement and 5 bar pressure, you would use the above chart to select an actuator with a 25 mm piston bore, a 4 mm nominal stroke and the over-travel modifier. These options would be used to generate the Piston Pump part number in the configurator below.

Kinitics KCD125 Controller

The Kinitics KCD125 Controller simplifies using Kinitics DC Linear Actuators and Piston Pumps by interfacing easily with PLC’s, control switches, relays, and standard I/O cards. Closed- and open-loop control using one or several inputs allows for a high degree of accuracy and repeatability while maintaining the actuator within recommended safety limits.

KCD125 | Key Features & Benefits

  • 6-24 VDC input
  • Compact size, DIN rail mounting
  • Internal temperature protection; fault notification
  • Discrete I/O allows for multiple control strategies

KCD125 | Discrete Inputs:

  • Enable: Driving of the actuator is conditional on the presence of a signal at the Enable discrete input.
  • Single: The actuator will stroke from its present position to its End of Travel position limit, triggered by the End of Travel switch input.
  • Pulse: The actuator will stroke from its present position to its End of Travel position limit, triggered by the End of Travel switch input. Once the actuator relaxes to its home position, as indicated by the Home switch, the controller will automatically initiate another stroke to End of Travel. The controller will continue in this manner provided the Pulse signal is maintained. A low-voltage, 100 Hz PWM signal can also be used at the Pulse input for complex control.

KCD125 | Analog Input:

  • Gain: This 4-20ma input allows complex control of a Linear Actuator or Piston Pump to be implemented. Feedback from a position, force or pressure sensor can be used in the PLC programming to adjust Gain as necessary to, for example, lift a part to a certain position or exert a specific force when holding an object.

KCD125 | Discrete Outputs:

  • Status: Indicates that a signal is present at the Enable input, and the controller is not in an over-temperature condition. The Status LED will switch from red to green to indicate that Status is active.
  • Home: Signals the actuator is in the Home position. The optional Home switch must be installed for this output to function.
  • End of Travel: Signals the actuator has reached its End of Travel.
  • Fault: Signals an error condition has caused DC voltage or current to be present at the load when the controller is in the off-state, or there is no voltage/current at the load when the controller is in the on-state.

Kinitics KCA020 Controller

The Kinitics KCA020 Controller simplifies using Kinitics AC Linear Actuators and Piston Pumps by interfacing easily with PLC’s, control switches, relays, and standard I/O cards.
