OPERATION
RUNNING THE PUMP IN REVERSE ROTATION
NOTICE:
Operate the pump in reverse rotation for no more than 10
minutes and only when a separate pressure relief valve
is installed to protect the pump from excessive pressure.
It may be desirable to run the pump in reverse rotation for
system maintenance. The pump will operate satisfactorily in
reverse rotation for a LIMITED time,
at a reduced
performance level.
FLUSHING THE PUMP
NOTICE:
If flushing fluid is to be left in the pump for an extended
time, it must be a lubricating, non-corrosive fluid. If a
corrosive or non-lubricating fluid is used, it must be
flushed from the pump immediately.
1. To flush the pump, run the pump with the discharge
valve open and the intake valve closed. Bleed air into
the pump through the intake gauge plug hole or through
a larger auxiliary fitting in the intake piping. Pump air for
30 second intervals to clean out most of the pumpage. A
drain plug is provided on the bottom of the cylinder to
facilitate cleaning.
2. Run a system compatible flushing fluid through the pump
for one minute to clear out the remainder of the original
pumpage. Restrict a valve in the discharge line to build
up 10 psi (0.7 bar) to force flushing liquid through the
bearing seal chamber.
3. To flush out the pressure relief valve (if equipped), close
the valve in the discharge line for 15 seconds while
pumping the flushing liquid.
4. If necessary, repeat steps 2 and 3.
5. To remove the flushing fluid, follow step 1 above.
NOTICE:
After flushing the pump some residual fluid will remain
in the pump and piping.
NOTICE:
Properly dispose of all waste fluids in accordance with
the appropriate codes and regulations.
