A dual rotor, ram fed metering pump is especially suited for pumping high viscosity fluids, such as methacrylate resins, used in heavy duty adhesives In addition to pumping viscous materials, this metering pump also pumps a less viscous reactive fluid in proper proportion to a mixing zone or mixing gun where the two material are mixed. A rotary lobe pump is used to pump the viscous material and a rotary pump driven by the same gearbox delivers the secondary fluid. This fluid delivery apparatus also includes an intake that can be mounted on a standard pressure primmer ram to pump viscous material from a storage drum or container A single compact all-in-one metering pump package can be mounted directly to the ram eliminating the need for a separate ram mounted pump.
A metering pump for use in pumping a first relatively viscous fluid and a second fluid to a mixing zone, the metering pump comprising:
2 The metering pump of claim 1 wherein the drive means comprises a gear box
The metering pump of claim 2 wherein the gear box is located between the rotary lobe pump and the auxiliary rotary pump.
An apparatus for transporting a viscous fluid directly from a shipping container to a mixing zone where the viscous fluid will react with a second fluid delivered to the mixing zone at a specified proportional rate relative to the flow rate of the viscous fluid, the apparatus comprising:
An assembly for dispensing a viscous resin and a catalyst to a mixing zone wherein the viscous resin and the catalyst react, the assembly comprising:
