Fluids If water-glycol mixtures are used (or fluids with a viscosity other than
that of pure water), an increase in power consumption of the pump is
to be taken into account. Only use mixtures with corrosion protection
inhibitors. The respective manufacturer’s instructions are to be
observed.
• Adjust the motor power if required!
• The fluid must be sediment-free.
• Wilo’s approval must be obtained for the use of other fluids.
• In systems built according to the state of the art, it can be assumed
under normal system conditions that the standard seal/standard
mechanical seal is compatible with the fluid. Special circumstances
(e.g. solid material, oils or EPDM-corrosive substances in the fluid, air
in the system etc.) may require special seals.
NOTE:
Always read and follow the material safety data sheet for the fluid
being pumped!

6 Description and function
6.1 Description of the product All the pumps described are single-stage low-pressure centrifugal
pumps in compact construction design with a coupled motor. The
mechanical seal is maintenance-free. The pumps can be installed
both directly as a pipe installation pump in a sufficiently anchored
pipe or placed on a foundation base. Installation options depend on
the size of the pump.
In conjunction with a control device (e.g. Wilo-CC/SC-HVAC-Sys-
tem), performance of the pumps can also be continuously controlled.
This allows optimisation of the pump output for the demands of the
installation and economically efficient pump operation.
Version IL:
The pump housing has an in-line design, i.e. the flanges on the suc-
tion and pressure sides lie along a centre line (Fig. 37). All pump hous-
ings are provided with pump support feet. Installation on a foundation
base is recommended for rated powers of 5.5 kW and higher.
