Soft Starter Pocket Guide
Mixer – a machine which combines ingredients.
Nameplate rating – See Full load current.
NEMA – a description of the soft starter’s physical format, according to
the National Electrical Manufacturers’ Association standard.
Pelletiser – a machine which turns powders into pellets.
Planer – a machine which draws boards over a cutting head to reduce
them to a specifi ed thickness.
Press – a machine which changes the shape and internal structure of
materials (usually steel).
Pump – a machine which moves fl uids.
Pump, bore – a submersible pump with a small diameter, suitable for
operation down bores/wells.
Pump, centrifugal – a pump with an impeller which causes fl uid to
rotate and move from the inlet to the outlet under its own momentum.
The fl uid’s velocity increases as it progresses through the impeller
passage. Diff user, ring or volute cavities reduce the velocity of the fl uid
and convert the energy into pressure energy.
Pump, positive displacement – a pump which reduces the volume of
the pump chamber to cause the fl uid to move. Positive displacement
pumps may be used for viscous fl uids, and include rotary (lobe, screw
or gear pump) and reciprocating (piston or diaphragm pump) types.
Pump, slurry – a centrifugal pump for pumping slurry.
Pump, submersible – a pump which is submerged in the fl uid to be
pumped. The sealed motor is close-coupled to the pump body.
Pump, vacuum – a pump which removes gas from a sealed chamber in
order to create a partial vacuum. Multiple vacuum pumps may be used
together for a single application.
Re-pulper – a machine which re-pulps raw product for further
processing.
