Pump control

PUMA pump control is a universal compact single-pump controller with the possibility of communication.

PUMA can operate both 1-phase and 3-phase pumps up to 12A (5.5KW).

PUMA is constructed with a two-part impact-resistant IP65 encapsulated housing.

The PUMA cabinet can easily be mounted on wall, in street cabinets and other enclosure due to its compact size of only 23cm in width.

The PUMA housing is designed for easy connection via bottom-mounted fittings and a combination of screw terminals and spring clamps.

PUMA pump control can be delivered, as standard without communication interface, or as an option 4G or NB/IoT modem,  which uses Modbus TCP/IP protocol for communication to either the AcowaCore/AcowaDash platform or to the user’s own SCADA-system.

All PUMA registers are of the same data type, so only one telegram is needed to be transmitted to get updated data. PUMA 4G and NB/IOT modems contain a “FAST RESPONSE” function and are developed to support the communication requirements of the future.

PUMA measures the level in the well via standard 4-20mA analog level transmitter and can start and stop the pump automatically. PUMA has integrated standard functions for inlet flow calculation, flow and capacity calculation as well as “Running blind”  control via the high-level float switch. PUMA has a unique function for current measurement on all 3 phases as well as phase sequence detection.

For daily operation, PUMA has a 2.4 ”OLED display in the front and 4 control buttons.

PUMA is configured with the common PC software – AcowaZoo. This is done locally via USB connector or remotely via 4G modem connection. Via the built-in USB connector in PUMA it is possible to perform firmware update.


  • Advanced single-pump control
  • Possibility of either 4G or NB/IOT communication interface with “FAST RESPONS”
  • Modbus TCP/IP protocol for communication with AcowaCore or users SCADA/SRO system
  • Unique function for current measurement on all 3 phases as well as phase sequence detection.
  • Operation via graphic 2.4 ”OLED display
  • Validated flow calculation, where the pump’s “true” capacity is calculated
  • Inlet flow calculation showing the inlet profile to the pump station
  • “Running blind”  function via level float switch if the pressure transmitter is faulty.
  • Possibility of overflow calculation via AcowaCore
  • Function for daily exercise of pump so that it does not get stuck during prolonged downtime
  • Function for daily depth pumping, so possibly. floating layers can be avoided
  • Possibility of varied starting level, so that fat build-up is avoided
  • Configuration of PUMA via AcowaZoo PC software
