Vertical Turbine Pump Lubrication Devices

The DripDoser – Water Well Oiler that saves money!
Return on investment in less than one year.


The DripDoser is a gravity-based oiler for Vertical Turbine Pump that saves you thousands of dollars and reduces down time.


  • Protection – Protects your irrigation vertical turbine pump from going dry.
  • Detection – Detects if there is any oil loss in your system.
  • Blockages – Detects if there are any clogged or pinched delivery input or output lines.
  • Control – Shutdown the pump and provides you with a fail-safe oil output alarm.
  • Prevention – Reduces the overall oil consumption and prevents ground water well contamination by providing the exact amount of oil required.
  • Monitor – Remote control and monitoring, providing peace of mind.

The DripMaster (EDD series) – is an active vertical turbine pump gravity-based control and monitoring lubrication oiler that maintains a constant oil drip rate.


The main function of the DripMaster is to maintain a constant oil drip rate while reporting back to the SCADA / cloud and shutting down the pump in case of lubrication risk.


By stabilizing the oil drip rate, the DripMaster overcomes oil drip rate instability caused by the following problems:


  • Oil viscosity variations.
  • Oil hydrostatic pressure variations.
  • Oil dirt particulate blockage.


The DripMaster reduces oil consumption and drastically reduces the amount of oil dripping into the aquifer, thereby minimizing groundwater contamination.

The DripGard – is a passive vertical turbine pump gravity-based oil lubrication monitoring, and protection oiler.

The DripGard’s main function is to send a signal when the oil drip rate falls below a predetermined level and then shut down the pump if there is a lubrication risk.

The DripGard prolongs the life span of the pump, saves money on oil consumption, and minimizes groundwater contamination.
