Exhaust Primer

Exhaust Primer – Air Operated Primers

download Exhaust Primer catalogue

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.
  • Example: displacement is 250 cubic inches; therefore you need an EP250-300. Adapter size is determined by size of exhaust tip and whether it is threaded or not.

  • INSTALLATION & OPERATION OF PROTEK EXHAUST PRIMER

    1. Use adapter to attach ejector to engine exhaust stack.
    2. Pump discharge must be closed while priming. This can be done by installing a discharge check valve or hand operated gate valve.
    3. Install vacuum gauge and priming valve on priming line, between the valve and ejector.*NOTE: Vacuum gauge should indicate priming rate of 18-22 Hg
    4. After priming is completed, lay handle and brass cap 180 degrees from priming position to allow exhaust to escape.
  • MAINTENANCE

    • Before every use, check the unit for accumulated build-up of dirt or soot from the engine exhaust.
    • If vacuum gauge is not working, replace before using EP.
  • SAFETY & RECOMMENDATIONS

    • EPs will not work effectively on single cylinder or two cycle (two strokes) engines.
    • Installing a Tachometer on the engine to determine exact speed is useful.
    • Line air leaks may prevent priming.
    • EPs can be used on turbo engines, provided that the RPMs are kept between 1100 and 1200.
    • This information is set forth in general terms for the benefit of distributors, but it is advisable that distributors provide appropriate instruction to their customers.
