1.6.1. Rotary connections
The suction and discharge connections can be rotated 180°. This simplifies the assembly
and installation of the pump. If you wish to rotate the connections, screw a threaded nipple
into the connection and rotate it. On the larger models T220, T420 and T820 it will be easier if
the housing nuts are slightly released while turning the connections.
1.6.2. Connection of suction pipe
Remember that the suction pipe/connection is the most critical point, especially if the pump is
priming. Just a small leakage will dramatically reduce the suction capability of the pump. When
connecting the suction pipe, the following is recommended:
1) For satisfactory operation, use a reinforced hose (the suction power may otherwise shrink
the hose) or other flexible piping. The internal diameter of the hose should be the same
as on the suction connection (at the bottom of the pump) to have best suction capability.
2) Make sure that the connection between the hose and the pump is completely tight,
otherwise the suction capability will be reduced.
3) Always use as short suction pipe as possible. Avoid air pockets which can emerge with
long piping.
1.6.3. Connection of discharge pipe
For this connection it is only recommended to have a simple and positive flow connection. Use
a hose or flexible piping (minimum one meter) between the discharge connection and any rigid
fixed piping. Coil the hose at least one turn. All components (hose, pipe, valves etc.) on the
discharge piping must be designed for minimum PN 10.
1.7. Health and safety
The pump must be installed according to local and national safety rules.
The pumps are constructed for particular applications. Do not use the pump on
applications different from that for which it was sold without consulting us to ascertain
its suitability.
1.7.1. Protection
In the interest of health and safety it is essential to wear protective clothing and safety goggles
when operating, and/or working in the vicinity of Tapflo pumps.
