Exhaust Primer – Air Operated Primers
Exhaust Primers (EP) are air operated primers comprised of an Ejector and cast iron Adapter that has a cap and handle attached. Unit operates on low engine exhaust pressure or air pressure from other sources. When the exhaust valve (adapter cap) is closed, gases are directed through ejector, and water is drawn to pump by ejector vacuum.
- *Note: When ordering an EP, ejector size is determined by engine displacement in cubic inches, and adapter size is determined by the outer diameter of the exhaust pipe and whether or not the pipe is threaded.
- Example: Engine displacement is 250 cubic inches, and the diameter of the exhaust pipe is 3 inches, therefore you need an EP250-300 3NPT.
Simple design, no moving parts.
Cast iron adapters come in a variety of sizes, to be mounted on a plain or threaded exhaust ends.
Priming can be completed in 10 seconds to two minutes.
Suction lifts of 20 ft. may be obtained under typical conditions.
Units are designed to produce vacuum of 18 to 22 inches of mercury (Hg).
