The Oiler - Small Volume Chemical Injection System

Brand: Welker, Inc
Easily prevent costly downtime caused by dry bearings with the Welker Original Oiler Small Volume Chemical Injection System.

This compact system automatically delivers a small fixed volume of your chemical - like lubricating oil - on a time or proportional to flow basis to keep your process running smoother for longer. The Oiler takes the labor out of difficult tasks for effortless operation.

Automatic Bearing Lubrication

Bearing systems like those in gas turbine TIC meters require periodic lubrication to prevent performance-reducing mechanical friction. The Oiler automatically delivers a small fixed volume of lubricant to prevent bearing burnout. The result? Optimal meter lifespan, performance, and accuracy.

Onboard Timing System

No external power supply? No problem! The long-lasting lithium battery pack of the Welker 6Tc Timer/Controller can power the Oiler. Set the 6Tc for proportional to flow or time-based chemical injection. This UL listed intrinsically safe controller is designed for hazardous areas.

Easy Access Reservoir

Thanks to the operator-friendly design, you can refill the 250-cc oil reservoir without even opening the enclosure. Simply remove the cap located on top of the enclosure and pour your injection chemical straight into the reservoir.

Corrosion-Resistant Enclosure

The Oiler can withstand a wide range of aggressive environments. The rain-tight, watertight, corrosion-resistant enclosure with integrated padlock hasp makes it ideal for remote locations. The clear cover allows for easy on-site monitoring of regulator pressure and chemical volume.

Compact Footprint

Where space is at a premium, this compact system will fit right in. The Oiler is mounted to a curved 8” x 13” panel, ready to be secured to a 2” pole or pipe stand using the included U-bolts. Because the Oiler is lightweight, system installation is easy and easy on you!

Backflow Protection

The outlet check valve protects operations during fluctuations in pipeline pressure. If pipeline pressure drops, rest assured neither injection chemical nor gas will flow from your bearing system back to the pump.
Features
  • Rain-tight, watertight, corrosion-resistant enclosure with padlock hasp and clear cover
  • Injection pump actuated by regulated process gas
  • Easy-access injection chemical reservoir
  • Panel-mounted
  • Onboard UL listed Welker 6Tc Timer/Controller (optional)
Benefits
  • Automatic consistent and even chemical injection
  • Confidently inject desired chemical in aggressive environments and remote locations
  • Easy on-site visual monitoring of regulator pressure and injection chemical volume
  • No auxiliary pneumatic supply required
  • Refill the injection chemical reservoir without opening the enclosure
  • Secure system to a 2” pole or pipe stand
  • System operates proportional to flow or time without an external power supply (optional)
