Consists of two separate parallel pump systems, one for the resin and one for the hardener. The two systems are operated simultaneously by a single lever. The pump dispenses PRO-SET Laminating and Infusion resins and hardeners at a 3:1 ratio by volume. This pump was designed to be connected to PRO-SET drums elevated slightly above the pump, via hoses and plumbing fittings available at most hardware stores. Because each set up will need to be customized for each fabricator’s needs, these are not included with the pump.
