Maintenance
There is very little maintenance required for a Bestobell Pressure
Operated Pump (POPS). Weekly and monthly maintenance is prac-
tically nonexistent for the application of these pumps, but periodic
maintenance should be performed once a year, depending on the
water source. At that time all strainers in the system should be
cleaned and tanks flushed to prevent the accumulation of rust, min-
erals and other contaminants.
Troubleshooting
A troubleshooting chart is shown below to enable you to isolate
any problems you may encounter when operating the Pressure
Operated Pump.
Figures 1 and 4 are POPS application drawings showing typical
piping. These drawings are typical in nature only and should not be
construed as piping for specific installations.
Figure 1 — Illustrates receiving 210° F above condensate
from a high-pressure steam source into a flash tank. The
steam condensate is separated with the condensate drain-
ing to a vented receiver. The flash steam is returned to the
heat exchanger. Condensate from the heat exchanger also
drains to the vented receiver. In turn, it fills the pressure
operated pump.
Figure 2 — Illustrates the POPS unit draining water from a
sump pit. (Total lift or backpressure is the height (H) in feet
x 0.433 plus PSIG in return line).
Figure 3 — Illustrates when draining equipment under a vacuum, a
pressure equalizer line must be installed to permit pump fill. (Total
lift or backpressure is the height (H) in feet x 0.433 plus PSIG in
return line).
Figure 4 — Illustrates draining condensate to a vented receiver and
returning condensate to boiler feed pump. (Total lift or backpressure
is the height (H) in feet x 0.433 plus PSIG in return line).
