Vertical turbine pump automatic lubrication

Oil lubrication control and monitoring devices:

Hoffmann & Hoffmann oil lubrication devices protect and manage vertical turbine pumps lubrication.

The devices are gravity-based and can be implemented wherever gravity-based lubrication is preferred.

We protect the line shaft bearings:

  • Improper lubrication of the line-shaft in vertical turbine pumps results in premature deterioration of the shaft bearings.
  • Approximately 80% of all bearing failures are caused by a lack of lubricating oil.
  • Instability of the drip rate is due to:
    • Viscosity variations.
    • Hydrostatic pressure variations.
    • Dirt particulate blockage.
  • Line shaft repairs are very costly and time consuming.
  • Groundwater contamination is caused by over-lubrication of the line shaft.

 

 Hoffmann & Hoffmann solution:

Hoffmann and Hoffmann vertical turbine pump oilers monitor and control line shaft lubrication to minimize bearing failure and ground water contamination and thus save huge amounts of money spent on premature degradation of line shaft bearings, oil consumption, and labor costs.

Hoffmann and Hoffmann oil lubrication products include the Dripdoser, the Dripmaster series and the Dripgard.

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 purpose 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:

  • 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 main purpose of the Dripgard is to signal when the oil drip rate falls below a predetermined low level (for any reason) while reporting back to the SCADA / cloud and shutting down the pump in case of lubrication risk.

By ensuring a constant lubrication when the pump is operational, the Dripgard prolongs the life of the pump, saving money on oil consumption, and minimizing groundwater contamination.

The DripDoser –is a gravity-based oiler for Vertical Turbine Pump that will save you thousands of dollars and costly down time.

  • Reduces pump maintenance costs.
  • Reduces labor cost – checking oil levels and adjusting drip rate.
  • Reduces oil consumption and prevents well contamination.
  • Maintains constant oil drip rate.
  • Protects your irrigation turbine pump from running dry:
    • Detects loss of oil supply.
    • Detects clogged or pinched delivery line.
  • Automatic pump shutdown.
  • Telemetry compatible remote control and monitoring.
  • Maintenance free and easy to install.
  • Operates under extreme weather conditions.
  • Low price – outlay quickly repaid.
