clark磁力驱动泵 CLARK SOLUTIONS AM Series Magnetic Drive Chemical Pumps Flow Rates to 55 GPM, Pressures to 22 PSI DESCRIPTION The AM series chemical pumps are centrifugal, horizontal axis, close-coupled type. The bodies are entirely built with reinforced thermoplastic polymers. Materials for the internal components include ceramic oxides, HD carbon and fluorinated elastomers. Any fluid contact with metallic pump parts is avoided. These chemical pumps are an excellent choice for small scale chemical pumping applications. FEATURES “Hermetic” Pump A drive magnet assembly (item 7 of cut away dwg.) is driven by the motor shaft. This magnetic field acts on the magnet that is molded into the impeller assembly (item 4). The rear casing (item 2) isolates the drive mechanism from the impeller assembly and the fluid media. 1) Volute Casing 6) SS Screws 2) Rear Casing 7) Drive Magnet Assembly 3) O-Ring Gasket 8) Support 4) Centrifugal Impeller 9) Flange for NEMA Motor 5) a/b Guide Bushings 10) Electrical Motor Safety & Life The magnetic drive system, which excludes any type of rotating seal, extends pump life. The only seal required is a static o-ring gasket between the volute casing and rear casing. The “R” version of the pump (see tables 2&3) has materials that tolerate dry running for 15 minutes to hours (depending on operating conditions and materials selected). Versatility & Performance Two housing materials, style WR, glass fiber reinforced (30%) Polypropylene, and style GF, Ethylene-ChloroTrifluoroEthylene carbon fiber filled (20%) are offered along with a choice of internal materials. Depending on material choice, the pumps handle applications from clean water to waste and slightly abrasive liquids, strong alkali or salts such as sodium hypochlorite, and acids such as chromix, nitric, sulphuric, etc.(see compatibility chart ). The mechanical properties of the reinforced housing materials allow the use of the pumps with fluids containing solids with medium grade of abrasion. For example a pump supplied with “X” internal materials (see table ) can handle solids up to an index hardness of Mohs 4, a maximum quantity in weight of 5%, and a maximum size of 0.25 mm. A selection of impellers accommodates a range of liquid specific gravities.
