1) Start the air compressor.
2) Open the air valve. Using a regulator to adjust the supply air pressure within the permissible range.
3) Open the flow valve on the discharge side.
4) First, check that fluid is flowing inside the piping and is being pumped to the discharge side, and then fully open the air valve.
Adjust the flow valve on the discharge side, or adjust the supply air pressure.
!
CAUTION
!
CAUTION
Before starting the pump, check that all piping is properly connected.
Before starting the pump, check that all the bolts are securely tightened.
Check that the regulator and the drain valve on the discharge side are closed and that the valve on
the suction side is opened if applicable.
The supply air pressure may initially rise during closing the flow valve. Make sure that the pressure is kept
within the normal operating range.
The permissible suction flow speed can vary depending upon the viscosity and specific gravity of the fluid,
the suction stroke and other factors. However in case of a rapid growth of the pump speed (flow speed of
fluid), cavitations will occur. This will reduce pump performance and may cause a malfunction. In order to
prevent cavitations, adjust the supply air pressure and the flow.
If fluid is not discharged after you start the pump, or if you hear an abnormal noise or notice any
irregularity, shut down the pump immediately.
11 I All-Flo Pump Co.

1) Remove the hose from the suction side of the pump.
2) Close the flow valve on the discharge side and open the drain valve. Then start air pressure for a
while to discharge possibly much fluid remaining inside the pump.
3) Remove the hose from the discharge side, and attach different hoses to the suction side and the
discharge side for cleaning.
4) Be ready with a vessel with cleaning solution, the kind appropriate for the type of fluid pumped. Next
connect the suction-side and the discharge-side hoses of the pump.
5) Start the pump air pressure slowly, and let the cleaning solution circulate for sufficient cleaning.
6) Flush with clean water.
7) Remove the hose from the suction side of the pump, run the pump for a while to purge the pump of
remaining fluid as much as possible.
!
CAUTION
!
WARNING
Make sure that compressed air is not supplied to the pump BEFORE you start cleaning the pump.
Make sure that the pump is not pressurized BEFORE you start cleaning the pump.
Be extremely careful when removing piping - the fluid will run/flow out.
After cleaning with clean water, turn the pump upside-down to let the water flow out.
12 I All-Flo Pump Co.

Close the air valve of the pump and shut off the supply air.
Before starting pump operation, conduct the following check procedures every day. In case there appears any
irregularity, do NOT start running the pump until the cause of the irregularity has been determined and
corrective measures have been taken.
a)Make sure that there is no leakage of fluid from any connection part or the pump.
b)Make sure that there are no cracks in the pump casing or piping.
c) Check the tightness of every bolt of the pump.
d)Make sure that the connection parts of the piping and peripheral equipment are not loose.
e)Make sure that any parts of the pump that are to be replaced at regular intervals have been changed.

CAUTION
!
CAUTION
The pump can be shut down with the flow valve closed while air is being supplied. However DO NOT leave
the pump in this condition for many hours without supervision - there is a risk of a leak from the pump or
piping, and fluid may continue flowing out of the position of leakage.
When the pump is shut down while pumping slurry, particulate matter contained in the slurry will be
deposited and get stuck inside the out chamber. Therefore after finishing work the pump must be cleared of
the remaining fluid. Otherwise when starting the pump again, the diaphragm may get damaged and the
center rod may bend.
Keep a vessel below the relief valve for any drain off.
Be careful! - Fluid under pressure will gush out the moment you open the valve.
If the pump is unused for a prolonged period, purge and clean it.

16.7 High Pressure System (option code HP)
All-Flo diaphragm pumps can be fitted with High Pressure option. It is a very compact unit that can be
mounted directly to the filter press. It has been designed for charging filter presses with chemical wastes and special
sludge. An extern pressure booster doubles or quadruples the delivery pressure.
Filter presses with All-Flo P300 pump
Automatic adaptation
When slurry is transferred to achamber filter press, first the chambers get filled while the pressure tends to zero.
Under the increasing filling-level the solids assemble at the filter cloths. This requires a pressure that continuously rises
with the increasing content of solids. Under a constant flow quantity the pressure would rise extremely fast.
The drive of the HP pump by compressed air causes adiminution of the flow quantity according to the increasing
counter-pressure in the filter press. This produces asoft filtration curve, automatically self-regulating according to the
filling level of the filter press. This is independent from the properties of the slurry. No pressure tank nor pressure
transmitter nor speed control are required. The complete HP pump works without electric energy.
End of filtration process
When the filter press is filled with the solids so far that no more slurry can be taken up, the pressing period is
terminated. The air operation of the All-Flo pumps then reduces the flow rate to zero while the outlet pressure holds
the required level compressing the filter cake. Excellent results in drying are obtained. At the end of the pressing period
the pump simply stops.
Pressure adjustment
The required pressure in the filter press is comfortably adjusted by the height of the air pressure supplying the
charging station. For arequired pressure of 12 bar the HP pump has to be supplied with 6bar when the pump with a
pressure transmission of 1:2 is applied. In the case that higher pressures are necessary or there is only alower air
pressure available, the HP pump with 1:4 transmission is applied.
Low air consumption
The charging stations needs the maximum air quantity only during the filling period. The more the press is filled, the
more slowly the pump works. So the air consumption slowly reaches zero during progressing filtration.
