Automatic,
Positive Pumping
Whenever air or vapor is present at the start of the pumping
operation – or when there is a loss of suction because
of air or vapor during pumping – the priming pump automatically
moves air and vapor from the suction line to the discharge
line.
Once
the flowing liquid from the centrifugal portion of the pump
builds up sufficient pressure in the discharge system, this
pressure backs up through a tube to act on the bottom of
the priming pump’s moveable slide block, placing it
in a neutral position. Under these conditions the priming
pump no longer evacuates air, but merely circulates a small
amount of liquid.
Roto-Prime
Pumps are actually two pumps in one. The small, powerful
vane-type pump within the main centrifugal housing can prime
an absolutely dry 4" (100 mm) line with zero back pressure
in approximately two seconds per foot without initial manual
priming. And this priming pump will evacuate suction lines
with back pressures up to 8 pounds per square inch.
Full Priming
With air or vapor in the lines, pressure of the spring on
top of the movable slide holds the priming pump in full
pumping position.

Full
Priming
With air or vapor in the lines, pressure of the spring on
top of the movable slide holds the priming pump in full pumping
position. |
|
|
Partial
Priming
As the pump evacuates air and vapor from the lines, liquid
pressure builds up on the underside of this slide, moving
it upward toward neutral. |
|
|
Neutral
When all air and vapor are removed, liquid pressure equalizes
spring pressure and the pump automatically slides into neutral…where
it remains until air and vapor again appear in the system.
