H&H oilers ensure consistent and optimal lubrication for vertical turbine pumps, preventing over- or under-lubrication.

This reduces bearing failures (which account for ~80% of pump breakdowns), cuts oil consumption, and minimizes groundwater contamination.

All models use optical sensors to detect and stabilize drop rates despite temperature-induced viscosity shifts or particulate blockages—ensuring consistent lubrication throughout the day.

Each device triggers an alert:

• DripMaster can automatically shut down the pump.
• DripDoser and DripGard activate an alarm relay, enabling pump shutdown or immediate notification.

Yes, they’re designed for automatic, maintenance‑free operation—stabilizing lubrication and raising alerts only if manual intervention is needed.

Ideal for vertical turbine pumps across applications like municipal water, agriculture, mining, oil & gas, and more, where precise lubrication and contamination control are critical.

No. H&H oilers are designed to retrofit most existing drip oiling systems with minimal modification. They are compatible with standard vertical turbine pump lubrication setups.

Hofman & Hofman (H&H) products come with a 2-year limited warranty under normal use.

Note that the warranty does not cover damage due to improper installation, external factors (e.g. power surges, extreme temperature conditions), or misuse. 

If a covered failure occurs during the warranty period, we will repair or replace the unit at no charge (customer pays shipping or installation if not included)

H&H systems work with a wide range of ISO-grade turbine oils. The optical sensors are calibrated to adapt to various viscosities, especially under temperature changes.

No calibration is needed in most cases. The systems self-adapt to flow conditions. If recalibration is necessary (e.g., after oil change), it can be done via a simple interface.

Yes. All H&H oilers include a limited warranty covering manufacturing defects and system failure due to normal use. Extended support plans are also available.

• DripDoser: Accepts 100–240 VAC (50/60 Hz) or 24 VDC. 

• DripMaster: Typical models support 115 VAC, 220 VAC, or 24 V AC/DC. 

• All models consume relatively low power (on the order of 10 W or similar) depending on whether active components are engaged. 

Be sure to check the specific configuration you order, as power requirements can vary slightly based on optional features.

Yes. When integrated into SCADA or cloud platforms, multiple DripMaster units can be monitored and managed centrally—ideal for facilities with large pump arrays.

If an alarm activates, it typically indicates one of the following:

• Oil tank is empty
• Input or output line is blocked or clogged
• Drip adjustment knob is set incorrectly (too restrictive or too high)
• Wiring or power issue

Steps to address:

1. Refill oil or check the tank.
2. Inspect & clean inline filters, tubing, and connections.
3. Adjust the drip rate knob or DIP switches carefully.
4. Reset the alarm (either via button or power cycling).
5. Monitor if the device returns to normal operation.
6. If issues persist, contact our support team for detailed diagnostics.
