If there is possibility of freezing at the air exhaust, it is good to pre-heat the air before it
reaches the air intake in order to raise the dew point of the air.
NOTE! Make sure that the air temperature does not exceed 50°C (122°F).
If icing / freezing is still a problem with the standard muffler, we recommend using our
heavy duty metal muffler. Contact us for more information.
2.3.
Pump stopping
The pump can be stopped in two ways:
1)
By closing of the discharge valve. The pressure from the system will stop the pump
automatically. The pump restarts easily when the valve is opened again.
NOTE! When using this method keep in mind that air must be supplied to the pump.
This is essential to keep the diaphragms in balance what protects them from premature
failure.
2)
By cutting off the air supply.
NOTE! When using this method make sure that the discharge valve is opened to relief
the pumps pressure.

Cleaning of the pump
2.4.1.
CIP – Cleaning In Place
The importance of easy cleaning is especially great in hygienic applications. Tapflo sanitary
pumps are designed for CIP (cleaning in place). This allows the pump to be internally
cleaned without disassembly. The pump can be cleaned by flushing through with a CIP fluid
(usually a mild solution of sodium hydroxide and a sanitizing additive) or by injection of hot
steam. The CIP fluid temperature varies, but in the sanitary field, the temperature is usually
about 90°C. Make sure that the CIP fluid is compatible with the materials in the pump/piping
(consult us for further information).
The solution is passed through the system by either the operation of the pump itself, or by
a centralized cleaning system. The CIP fluid must pass through the pump at a minimum
velocity of 1.5 m/s in the normal flow direction (from inlet to outlet).
It is recommended to run the pump slowly during CIP. This is to obtain pressure balance on
both sides of the diaphragm. Lack of pressure balance will have influence on the pump’s
lifetime. For more information please contact us.
