Welker Oiler Chemical Injection System

The Oiler

The Oiler

The Welker Oiler Small Volume Chemical Injection System automatically delivers a fixed volume of lubricating oil or chemical to turbine meters, gas measurement facilities, and machinery bearing systems that require periodic lubrication. Designed to operate on a time-based or proportional-to-flow basis, The Oiler helps reduce manual lubrication, prevent dry bearing damage, and keep processes running smoothly. With a rain-tight, watertight, corrosion-resistant enclosure, process-gas-actuated injection pump, easy-access chemical reservoir, panel mounting, and optional Welker 6Tc Timer/Controller, The Oiler supports reliable lubrication in remote and aggressive environments.

Where to Use

Turbine Meter Lubrication

Gas measurement facilities where turbine meter bearing lubrication is required.

Machinery Bearing Systems

Equipment that requires periodic lubrication to reduce wear and prevent downtime.


Rain-Tight, Watertight, Corrosion-Resistant Enclosure

Protects the system in remote and aggressive environments.

Process-Gas-Actuated Injection Pump

Delivers automatic, consistent chemical injection without auxiliary pneumatic supply.

Easy-Access Chemical Reservoir

Allows visual monitoring and refilling without opening the enclosure.

Panel-Mounted Design

Secures easily to a 2-inch pole or pipe stand.

Optional 6Tc Timer/Controller

Allows operation proportional to flow or time without an external power supply.
