2. OPERATION

2.3

Starting and operating

-

Open the discharge valve.

-

Note! Considering the suction capacity when air is still in the suction pipe, it is
recommended to start with low air pressure/flow in the beginning. This is not necessary
if the pump is filled with liquid before start.

-

When the pump has been filled with liquid, the air pressure/flow may be raised to increase the
suction capacity of the pump.

-

The performance of the pump can be adjusted through the air supply by using a needle valve
and a pressure regulator. The performance can also be adjusted by normal flow control on the
discharge side of the system.

2.3.1

Dry running

The pump may run dry without any problem.

2.3.2

Optimizing the pump lifetime

Running at full frequenzy (maximum air pressure/flow) continiously will cause premature wear of
the components. As a general rule, we recommend to run at half of the maximum capacity of the
pump. For instance, a T80 pump should run continious maximum at 40 l/min.

2.4

Pump stopping

The pump can be stopped in two ways:

1) Close the discharge valve. The pressure from the system will stop the pump automatically. This

will not do any damage to the pump. The pump restarts easy when the valve is opened again.

2)  Stop the air supply.

2.5

Cleaning of the pump

2.5.1

CIP - Clean in place

The importance of easy cleaning is especially great in hygienic applications. Tapflo stainless steel
pumps are designed for CIP (clean in place). This allows the pump to be internally cleaned without
strip down. 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 tempera-
ture 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 from 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).

2.5.1.1

Drainage of the pump (T80-T425)

After the CIP procedure, the pump usually has to be drained from the
CIP fluid. The Tapflo stainless steel series is supplied with a hygienic
stand, enabling 360° rotation of the pump unit.

1) Disconnect the pump from the pipings.

2) Simply loosen the two socket head cap screws (pos 4) and

rotate the pump 180° and let the remaining fluid drain off. The
airline may be left connected during this rotation.

3) Rotate back to normal position, connect the pump with the pipings

and fix the socket head cap screws (pos 4).
