PF-Series Pressure Based Pump Control – Variable Pressure

Electronic Pump Controller

Multiple Booster Pump Controller


Pressure control of multiple pumps from a single Control Panel and pressure sensor. Fixed speed variable pressure pump control with adjustable start and stop pressures per pump, and intuitive menu driven options.

The pump pressure sensor is separate from the Control Panel allowing installation either close to the pumps as in a chassis mounted pump set, or for use with submerged pump sets for maximum performance, silent operation and reduced space requirements.

Monitoring of the supply tank/break tank via either float switch, conductivity probe, or analogue level sensor. Level sensor models have accurate level display and minimum level adjustment from the Control Panel.

Advanced Fault Tracking logs faults as they occur. Fault codes are stored in memory until you choose to erase them, allowing easy identification of intermittent and historical Faults.

Clever design of the circuit board provides the most robust unit on the market today, with overvoltage and brownout protection, immediate recovery from power failures with no loss of setting and auto reboot, individually fused outputs, oversized power supply to electronics, removable MCU chip (software) for easy upgrades, automatic failover of pumps, and automatic search for spare pumps even if not configured for twin pump use. Modular connector design and tolerant software allows pumps to be ‘hot-swapped’ without switching off the controller or remaining pump. Designed, programmed, built and assembled in the UK. With full UK based technical support , rapid spares availability, and spare parts supply from UK stocks, with full repair/recon service to component level.

OEM Solutions

3P Control Panels are supplied either as a panel only, or can be offered as a kit, comprising of the panel, pumps, cables, pressure vessel, hose kits, etc.

We work with our customers to provide specific product bundles, with panel and software branded to your requirements.

We provide full training, design and technical support, and will customise the product and accessories to your requirements, and full UK based support and spare parts availability.



  • Can be used in a packaged booster set (skid mount) or distributed installation.
  • Excellent configurability whilst retaining an intuitive menu driven user interface.
  • Made in Britain. Designed, built and programmed entirely in the UK by 3P Technik.
  • Full UK support , with customisations to hardware and software available with very short lead times.
  • Modular design allows extremely rapid swap-out of parts. Including hot-swap of pumps and sensors (no power-off). Also no need to match replacement pumps.
  • Very low lead times. All spare parts stocked by us in the UK for immediate dispatch. We don’t follow the ‘buy to order’ business model of continental manufacturers whose lead times are often unsuitable for UK clients.
  • We can supply not only the control equipment, but also pumps, filtration and all tank fittings.
