Our customer’s chemical dispensing system provides versatility for metering and dispensing of a wide variety of fluids used for caulking, joint and crack filling, sealants and adhesives. They needed a custom chemical metering pump which reliably dispenses several types of chemicals and resist corrosion.
Cascon designs custom gerotor type pumps specifically for applications requiring high metering accuracy. This positive displacement chemical metering pump is designed for use with a wide range of fluids including single and plural component urethanes, epoxies, silicones, and polyureas. Operating speeds are typically under 1000 rpm and discharge pressures are in the range of 300 to 1000 psig. The housings and eccentric ring are constructed from cast iron bar, which are then electroless nickel plated for wear and corrosion protection. The shaft is made from carburized and hardened AISI 8620 steel. The bearings are simple journal bearings, and the rotors are heat-treated PM.
