Fluids
Water-glycol mixtures or fluids with a different viscosity than pure water increase the
power consumption of the pump. Only use mixtures with corrosion protection.
Observe
the relevant manufacturer’s specifications!
ƒ
Adjust the motor power if required.
ƒ
The fluid must be sediment-free.
ƒ
Wilo’s approval must be obtained for the use of other fluids.
ƒ
The compatibility of the standard seal/standard mechanical seal with the fluid is
generally given under normal system conditions.
Special circumstances may require special seals, for example:
–
solids, oils or EPDM-attacking substances in the fluid,
–
air content in the system, etc.
Observe the safety data sheet for the fluid to be pumped!

Description of the pump
All the pumps described here are low-pressure centrifugal pumps in compact construc-
tion 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.
The installation options depend on the pump size. Suitable Wilo control devices (e.g.
Wilo-CC-HVAC system) can control the power of the pumps continuously. This allows
optimisation of the pump output for the demands of the installation and economically
efficient pump operation.

The pump housing has an in-line design, i.e. the flanges on the suction and discharge
sides lie along a centre line. All pump housings are provided with pump support feet. In-
stallation on a foundation base is recommended for rated powers of 5.5 kW and higher.
