5.2 Suitable fluids:
• Heating system hot water.
• water and water/glycol mixtures up to a 1:1 ratio. Use of glycol mixtures require
a reassessment of the pump hydraulic data in line with the increased viscosity
at the various mixing ratios. Only approved makes of additives with corrosion
inhibitors must be used in strict compliance with manufacturers’ instructions.
• For the use of other fluids contact Wilo first.
5.3 Scope of supply
• Pump, according to version, with installation and operating instructions

6 Description and function
6.1 Pump description
The Pump is shown in (Fig. 1).
The circulating pump is fitted with a wet (canned rotor) motor. The motor housing
is with an electronic control module (Fig. 1, Item 1) capable of maintaining the
pump generated differential pressure variable (p-v) at a preset value between 1
and 16 feet. Pump capacity is thus matched to the changing load demand which
is particularly significant when using thermostatic control valves.
The essential advantages and benefits are:
• no bypass relief valves required
• power consumption savings
• improved air removal
• improved heat control
• reduction of flow noise
