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.

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.
