Hand Diaphragm Primer

THE DIAPHRAGM PRIMER contains a rubber diaphragm working in an aluminum chamber. A levered handle attached to it by a connecting rod actuates the diaphragm. Air is drawn into the chamber through a suction valve on the up-stroke and discharged through a discharge valve on the down-stroke. The primer body is made of a light weight aluminum alloy. The diaphragm is of molded rubber, and it is extremely tough and longwearing. A rubber air discharge valve, built into the diaphragm, provides a positive seal. We manufacture #5 Diaphragm Primers(DP5), #7 Diaphragm Primers(DP7), and #9 Diaphragm Primer(DP9).

Manifold Primer

THE MANIFOLD PRIMER combines all of the time-tested advantages of using an engine manifold vacuum to evacuate air from suction lines, with the latest engineering design and materials. All the internal parts are enclosed in a fully transparent chamber made of heat-and shock-resistant plastic so that the operator can observe their functioning.
