Where a pump forces the water through the filter-or-As a vacuum
filter where a pump suction is placed on the discharge side of the
filter and draws the water through the filter rather than pushing it
through. The filter element or septum must be coated with
diatomaceous earth (skeletal remains of diatoms) which acts as the
filtering medium. During operation, additional DE, which is called
body feed, must be added with the incoming flow to guard against
filter breakthrough . A crack in the media can allow microorganisms
to easily pass through.

,Simplest type of all AC motors. Rotor windings are steel bars placed
in slots on the rotor and attached at each end. Current flowing
through the stator winding establishes a rotating magnetic field.
Magnetic field in turn induces a voltage in the rotor windings, which
creates an opposing magnetic field on the rotor causing the motor
to turn. Can be used in applications requiring a high starting torque
without special starting circuitry.

Definition
Most commonly used in water systems. Water thrown outward from
the center of impeller and into the volute or diffusers. Velocity is
converted to pressure in the volute or diffusers. Multistage pumps
increase pressure at each stage but flow capacity limited to first
stage.

A load that acts parallel to the axis of rotation. A thrust bearing
compensates for the axial thrust of a shaft.
