Fluids

If water/glycol mixtures with up to 40% glycol (or fluids with a differ-
ent velocity to pure water) are used, the pump data must be corrected 
to match the higher viscosity, regardless of the percentage mixture 
relationship and the fluid temperature. The motor power must also be 
adjusted if necessary.

• Only use mixtures with corrosion inhibitors. The respective manufac-

turer's instructions are to be observed.

• The fluid must be sediment-free.
• Wilo's approval must be obtained for the use of other fluids.

NOTE
Always read and follow the material safety data sheet for the fluid 
being pumped.

Description  and  function

6.1

Description of the product

The single-level low pressure IPS centrifugal pump is equipped with a 
flanged-mounted standard motor and a rigid coupled pump shaft. 
The grey cast iron pump housing has an in-line construction, i.e. the 
suction and pressure ports lie along a straight line. The pump shaft is 
sealed with a force-flushed bellows mechanical seal. The pump is 
designed as an in-line pump. The pump weight and the position of its 
centre of gravity enable all pump sizes to be attached directly to the 
piping. This requires the pipe to be appropriately secured to the struc-
ture.

In conjunction with a Wilo control device, the flow rate 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.

Installation  and  electrical connection

Safety

DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can be 
life-threatening.

• Have the electrical connections established by approved electri-

cians only, in compliance with the applicable regulations!

• Adhere to regulations for accident prevention!

DANGER! Risk of fatal injury!
Failure to install safety devices on the motor, terminal box or on 
the coupling can cause electrical shock or contact with rotating 
parts, potentially resulting in life-threatening injuries.

• Before commissioning and after maintenance work, all safety 

devices (such as terminal box covers or coupling covers) that were 
removed must be reinstalled.

• Keep a safe distance during commissioning.
• Always wear protective clothing, protective gloves and protective 

goggles when working.

WARNING! Risk of injury due to the weight of the pump!
The pump itself and pump parts can be extremely heavy. Falling 
parts pose a risk of cuts, crush injuries, bruises or impacts, which 
may lead to death.
