Air Valve System
from Elima-Matic Pumps

True to their name, ELIMA-MATIC® pumps virtually eliminate intermittent pump stalling caused by Air Valve System freeze-ups. By utilizing the patented non-icing, lubrication-free valve system, this common air diaphragm pump problem is a thing of the past.

Eliminating Downtime
ELIMA-MATIC® ensures continuous, reliable pump performance.
Here's how it works:
The valve spool is positively shifted by the transfer of a pilot shaft. When the main shaft travels to full-stroke length, the inner piston on the opposite side depresses an internal pilot shaft which ports a burst of compresses air to the main spool valve. The main spool valve reciprocates in a positive reliable shift. As the pilot shaft moves back and forth, an air burst is ported to the main spool which causes it to shift every time, eliminating stalling.

Losing Your Cool
By evacuating compresses air through air passages that are designed to allow a controlled expansion, a considerable reduction in the cooling effect occurs. In addition, the center block and air valve surface areas are ribbed and act as heat exchanges to dissipate the rapid cooling effect.

Ease Of Maintenance
The ELIMA-MATIC® not only eliminates freezing and stalling, but maintenance headaches as well. The ELIMA-MATIC® has only two easily accessible center block o-rings -some competitors pumps have as many as seven. The pilot shaft o-rings come out as a complete assembly and are easily replaced without the use of an o-ring tool. And the air valve can be worked on without taking the pumps center section apart.

Maximizing Pump Performance
Versa-Matic pumps can already handle anything from water to 90% solids easily and efficiently. Add the ELIMA-MATIC® Air Valve System and you've got a pump that offers powerhouse performance.

Air Valve Upgrades
Also available as a conversion kit for Versa-Matic V4, V2 and V3 pumps, as well as Wilden® 1 ¼", 2" and 3" metallic pumps, the ELIMA-MATIC® comes with either an aluminum, stainless steel, or Teflon-coated air section. (The air chambers, air valve and center block can be nickel-plated for diverse applications.)
