NOTE:
NOTE: The pump was built and tested using a food
grade lubricant.
Properly sanitize the pump before first use. The
user must determine whether to disassemble and
clean individual parts or simply flush the pump with a
sanitizing solution.
To simply flush the pump with a
sanitizing solution, follow the steps under
Start and Adjust the Pump, page 20
and
. To disassemble and
clean individual parts, refer to the appropriate Repair
manual.

When the center section air pressure is at least 0.7
bar (10 psi) higher than the desired outlet pressure,
the pump is in Transfer Mode and no pulsation
damping is occurring. To reduce outlet pulsation,
start by setting the center section air pressure
equal
to the desired outlet fluid pressure. Use the
center section regulator (R) to continue to adjust the
center section air pressure relative to the outlet fluid
pressure. Lower relative center section air pressures
produce more pulsation damping. Higher relative
center section air pressures produce better pump
efficiency.

NOTE: Low pulsation mode may invalidate the

1.
Confirm that the pump is properly grounded. See
2.
Check and tighten all pump clamps and fluid
connections before operating the equipment.
Replace worn or damaged parts as necessary.
3.
Connect a flexible fluid suction line (K) from the
fluid to be pumped to the pump fluid inlet port (B).
4.
Connect the flexible fluid outlet line (N) to the
pump fluid outlet port (C) and route the line to
the end container.
5.
Close the fluid drain valve (L).
6.
Turn the air regulator (H) and center section
regulator (R) knob to the lowest air pressure
setting and open the bleed-type master air valve
(G).
7.
If the fluid outlet line (N) has a dispensing device,
hold it open while continuing with the following
step.

VFD: Set the desired frequency and press the

9.
To prime the pump, slowly increase air pressure
with the air regulator (H) and center section
regulator (R) until the pump starts to cycle. Do
not exceed the maximum operating air pressure
as listed in the
. Allow
the pump to cycle slowly until all air is pushed out
of the fluid lines and fluid exits the outlet line (N).
NOTE:
NOTE:
NOTE: If the fluid inlet pressure to the pump is more
than 25% of the outlet working pressure, the ball
check valves will not close fast enough, resulting in
inefficient pump operation. Inlet fluid pressure higher
than 25% of the outlet working pressure will also
shorten diaphragm life. Approximately 0.21-0.34 bar
(0.02-0.03 MPA, 3-5 psi) fluid inlet pressure should
be adequate for most materials.
