VERTiCAL TURBiNE PUMP AUTOMATiC LUBRiCATiON

H&H 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.

OiL LUBRiCATiON CONTROL & MONiTORiNG DEViCES

Our 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.

PROTECTiNG LiNE SHAFT BEARiNGS

The  DripMaster is designed 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:

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

Make significant savings by avoiding costly and complex repairs, well downtime, oil consumption and labor intensive on site visits.

FULLY AUTOMATiC MAiNTAiNANCE FREE

Fully automatic, maintenance-free, providing remote alerts on pump failures and securing your peace of mind.

GARANTEE PROPER LUBRiCATiON

Proper lubrication of the line-shaft in vertical turbine pumps reduces premature deterioration of the shaft bearings. Approximately 80% of all bearing failures are caused by a lack of lubricating oil. H&H gravity base automatic oilers maintain stable and constant oil drip rate, overcomes oil drip rate instability caused by the following problems:

  • Oil viscosity variations cause by temperature changes through the days and seasons.
  • Oil tank hydrostatic pressure variations.
  • Oil dirt particulate blockages which prevent a stable oil flow.

STABALiZE THE DRiP RATE

H&H identifies and quantifies the oil flow drip rate and stabilizes it to the exact number of oil drops required. Pre-Lub functionality keeps your bearings constantly lubricated avoiding the pump starting on dry bearings.

PERFECT DRiP RATE

Control and actively maintain a constant oil drip rate regardless of the ambient temperature which affects the oil viscosity or hydrostatic pressure in the oil tank.

By utilizing pre-lub functionality H&H ensure that the minimum amount of oil is used to avoid pump start on dry bearings. All of our units feature built-in optical sensors at the oil outlet to monitor the actual drip rate. These sensors detect whether the drip rate is as desired, higher, or lower than the target rate.

DripMaster

The DripMaster is a fully automatic oiler uses a built-in servo motor connected to a needle valve. The motor automatically adjusts the valve (opening or closing it) to maintain the exact drip rate that has been selected.

DripDoser

The DripDoser allows you to configure a specific drops-per-minute (dpm) rate using an internal dip switch (e.g., 10 dpm). You can adjust the delivery speed to ensure the set number of drops is delivered quickly to compensate for temperature variations. This ensures consistent oil dosing to the pump, regardless of changes in oil viscosity.

Pump Protection

If the drop count deviates from the set rate, an alarm relay activates, allowing the user to shut off the pump or send a notification.

Our products enable precise control over the oil drip rate, ensuring optimal performance and preventing under- or over-lubrication.

NO GROUND WATER CONTAMiNATiON

H&H oilers significantly reduce the amount of oil dripping into the aquifer by optimizing oil consumption, thereby minimizing groundwater contamination. Our units provide the exact amount of oil needed, precisely when it’s needed.

By controlling oil usage, we not only save on costly oil consumption but also reduce the risk of excess oil seeping into groundwater.

In cases where food-grade oil is used, minimizing oil usage also decreases the potential for bacterial and biological contamination, ensuring that only the necessary amount of oil is applied, further protecting the environment.
