6.2 Design of pump and motor
This wet rotor pump is designed to have all rotating parts surrounded by the liquid being pumped and
is suitable for single or three phase operation (see pump rating plate). A shaft seal, which would be sub-
ject to wear and maintenance is not required. Depending on the design of the pump, the system fluid
lubricates the sleeve bearings and cools both bearings and motor. The pump is maintenance-free and
requires no further maintenance after the air bleeding procedure during the initial start-up (no after
start-up maintenance).
The Wilo model TOP-Z is specially designed for use in conjunction with drinking water circulation sy-
stems. Thanks to its design and materials used in its construction the pump is resistant to corrosion
from elements in domestic hot water ( drinking water). All materials coming in contact with the deli-
very medium are NSF/ANSI 61 certified.
6.3 Functions
Speed setting of TOP-S.../TOP-Z... pumps (Fig. 5 and Fig.6)
The required speed of the pump can be adjusted manually in 2 positions (Max. and Min.) by mo-
ving the switch connector to the relevant socket. Procedure see Chapter "8.2 speed setting".
Ensure power is turned off prior to changing speeds!

The pump must be installed in an easily accessible position to facilitate inspection or replacement.
x
The pump should never be located at the lowest point of the piping system, where dirt and se-
x
diment collect. Nor should it be located at the highest point of the piping system, where air ac-
cumulates. Please ensure at least a minimum of three pipe diameters of straight on the suc-
tion side of the pump.
