Section 1: Introduction
Overview
The Dripmaster is an active vertical line-shaft lubrication control and monitoring device. It
automatically stabilizes the oil drip rate so as to comply with pump manufacturer's requirements.

Constant drip rate is maintained regardless of ambient temperature or hydrostatic pressure in the
feeding oil tank. This is achieved by monitoring and controlling the drip rate 55 times per hour.
There are two modes of operation:
•
Normal (pump on) mode
—when the well pump is operational
•
Pre-lube (pump off) mode
—ensures that the line-shaft is lubricated prior to turning on the well
pump.
Automatic switching between the Normal (pump on) and Pre-lube (pump off) modes is achieved by
remotely sending a control signal to the Dripmaster.
The SCADA interface provides:
•
Accurate oil consumption data (drip rate count)
•
Total lack of oil warning
•
Automatic pump shutdown
A built-in manual mechanism ensures oil flow even in the remote possibility of unit malfunction.
