Nameplate rating – See Full load current.
NEMA – a description of the soft starter’s physical format, accord-
ing 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 specified thickness.
Press – a machine which changes the shape and internal structure
of metals (usually steel).
Pump – a machine which moves fluids.
Pump, bore – a submersible pump with a small diameter, suitable
for operation down bores.
Pump, centrifugal – a pump with an impeller which causes fluid
to rotate and move from the inlet to the outlet under its own
momentum. The fluid’s velocity increases as it progresses through
the impeller passage. Diffuser, ring or volute cavities reduce the
velocity of the fluid and convert the energy into pressure energy.
Pump, positive displacement – a pump which reduces the
volume of the pump chamber to cause the fluid to move. Positive
displacement pumps may be used for viscous fluids, 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 fluid 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.
Rotary table – a large rotating table which is used to sort or move
material.
