The HAND DIAPHRAGM PRIMER is an air pump designed to create vacuum in a centrifugal pump's priming line and pull water up into the pump for priming. Equipped with a flapper check valve in the diaphragm and a disk check valve at the bottom, this Diaphragm Primer operates by allowing air to flow through the bottom check valve during the upstroke, and then through the diaphragm valve during the downstroke. The diaphragm is activated by a connecting rod eyebolt that is attached to a fulcrum handle bracket.
FEATURES:
• Lightweight aluminum alloy body
• Easily mounted on most centrifugal pumps
• Tough and durable rubber diaphragm
• Units have a drain valve
