Approved circulator mounting arrangements :

Viscous fluids / Hydraulic data

All hydraulic data contained in this catalogue are based on handling water having a kinematic viscosity = 1 mm2 / s

Water / glycol mixtures allowed, mixing rate (max 1.1).

The hydraulic values of the pump and of the pipe system change when such liquids of different densities and/or viscosities are pumped.

Above 20% admixtures, the pumping data must be checked.

These data are measured after a minimum of 12 hours of running-in.

Minimum inlet pressure to prevent cavitation

To avoid cavitation (vapor forming within the circulator) it is necessary to maintain at the circulator suction port an adequately high positive pressure (static head) in relation to the vapor pressure of the fluid being handled.

For higher altitudes: add 0.1m head/100m height increase.

These minimum heads must be respectively increased when handling fluids of higher temperatures or lower densities, higher resistances at the circulator suction side and in regions of lower atmospheric pressures.

Condensation

Circulators listed as being suitable of handling chilled water down to –10°C are fully condensation-proof.

Working Pressure

Maximum working pressures to which circulators can be internally subjected to: PN3, PN6 or PN10 (see type plate)

Electrical Wiring

> All Wilo and Salmson circulators are suitable for wiring to the appropriate European standard voltage 230V (+10% / -15%) to IEC 60038 standards

> Frequency : 50Hz ±5%

> All Wilo and Salmson circulators with CE-mark according to EC Low Voltage Directive (P1≤300W) or EC machinery directive (P1>300W)

Automatic performance control

Heating circulating circulators are, due to their high annual operating

hours, among the largest power consuming appliances in buildings.

Their power consumption can however be considerably reduce when

operating them in conjunction with an automatic performance

control system; savings of up to 50% are thus attainable.

Automatic performance control will hydraulically optimise operations

at all load conditions, particularly the problematic low-load periods

so typical in central heating.

A further significant effect is the avoidance of flow noise generated

at thermostatic radiator valves due to the prevention of undue head

increases.

Specific functions

Self regulating pumps provide specific features:

In Δp-c control mode, the electronic module keeps the differential

pressure generated by the pump constant at the differential pressure set

point HS over the permissible volume flow range.

In Δp-v control mode, the electronic module changes the differential

pressure set point to be maintained by the pump in linear fashion

between Hs and ½Hs. The differential pressure set point value varies with

the volume flow Q.

The choice of the control mode must be made by qualified personnel

during installation according to pipe losses characteristics.

Air venting routine

An air venting routine is implemented to help the installer to drain air out

of the heating installation. This routine can easily be selected turning the

red button to the middle position. It runs 10 minutes by alternating low

and high speeds of the pump. At the end of the process, the pump

automatically switches to a preset speed. The installer can then select the

requested setting with the red button.

PWM regulation

Interface specificationSignal polarity : both PWM frequency range : 150 Hz to 4 kHZ

PWM voltage range :

Required control current : 4 mA @ 5V7.5mA @ 15V

Description: the PWM module receives the signal from the boiler controller and switches the circulator into one of the power stage or rotation speed. There is no possibility to read out any information from the module (unidirectional interface).

General points for pumps in heating systems

WILO pumps operate best with clean, good quality tap water.

The most frequently occurring factor which may have a negative effect on heating water can be oxygen, lime, sludge, acidity level and other substances (including chlorides and minerals).

In addition to the heating water quality, the installation also plays a significant part. The heating system shall be tight.Materials shall de chosen which are not sensitive to oxygen diffusion (corrosion risks…).

New heating systems

In the case of new installations, it is first of all crucial to flush the entire installation thoroughly (without the pump mounted) before the central installation is commissioned. This will remove residue from the installation process (weld, slag, fitting products…) and preservatives (including mineral oil).

The system shall then be filled with clean, good quality tap water.

Existing heating systems

If a new boiler or heat pump is being installed in an existing heating system, the system must be flushed to avoid particles presence, sludge and other problems in the installation. Where applicable flushing shall be done before the new application is installed.

Loose dirt can only be removed where there is sufficient flow. Flushing will therefore take place section by section. Special attention must also be paid to « blind spots », where there is only a small amount of flow and where a lot of dirt can be accumulated.


If after the flushing the quality of the water in an existing installation proves still to be inadequate, certain measures must be taken to avoid pump problems. One option for removing pollution is to install a filter. Various kinds of filters are available for this. A screen filter is designed to trap large dirt particles. This filter is usually placed in the full flow part of the system. A fabric filter on the other hand, is designed to trap finer particles.

Very old heating systems or systems open to air

In heating systems which are open to air corrosion inhibitors shall be used. The product must be suitable for all materials used in the central heating installation. The supplier of the corrosion inhibitor must be consulted in this regards. Its usage regulations and instructions provided by the supplier of the water treatment product must be followed.

In old heating systems which remain very dirty after flushing, the usage of cleanser may help. The product must be suitable for all materials used in the central heating installation. The supplier of the cleanser must be consulted in this regards. Its usage regulations and instructions provided by the supplier of the water treatment product must be followed. Particular attention must be paid on the full removal of the cleanser from the heating installation.

Given that a variety of water treatment products are available, it is not feasible for WILO to investigate all possible products. A number of well-known manufacturers and their products are :

Fernox : - Protector F1- Restorer F3

Sentinel : - X100- X400

Agent from the other manufacturers may also be used, provided the relevant manufacturer guarantees that it is suitable for all materials used and is corrosion resistant.


Forbidden materials

Some materials must not be used in installation because of too low PH value, composite attack, e.g. :

- Leak sealer- Nutritive acid and deoxidant acid- FERNOX DS40 system cleaner

Modulating circulators : PWM series

Series PWM circulating circulators are intended for use in hot water heating systems of variable volume characteristics. The integrated electronic module is driven by a PWM signal from the boiler controller and switches the circulator into a specific power stage.

The main benefits are:

> Power savings

> Reduction of flow noise

> No bypass required for pressure adjustment

The first two points are generated by the speed reduction of the circulator. This reduction is effective most of the time as soon as the external temperature is higher than 5°c.

Concerning the last point, the bypass is not needed for pressure adjustment because the differential pressure reduction required is provided by the PWM circulator. Moreover, the water temperature increase on the heating return circuit with the bypass does not occur any longer. This is especially advantageous for condensing boilers.

For sanitary hot water heating, the circulator can be automatically switched to the high speed to improve the thermal efficiency inside the sanitary heat exchanger. This characteristic cannot be achieved with a standard circulator with a manual set point permanently fixed by the installer.

The electronic PWM module can supply the circulators type ../Premium, ../4.1, ../6 or ../7 with :

> Cast iron in line circulator housing with or without air venter

> Composite in line circulator housing with or without air venterRS.. Ku or RSL.. Ku (not RSB)

Self regulating pumps : E../1-5 series

Series E../1-5 circulating pumps are intended for use in hot water heating systems of variable volume characteristics. The pump-integrated electronic differential pressure control provides variable speed control to match pump capacity to the actual load demand.

The motor housing is fitted with an electronic control module capable of maintaining the pump generated differential pressure constant at a preset value between 1 and 5 m. The pump continuously adapts itself to the necessary load of the installation following the opening or closing of thermostatic valves.

The pump allows two different settings with differential pressure control: turning the red button right or left ΔP-c or ΔP-v. By selecting the middle position, the pump launches the air venting routine.

Connection system

For the power supply, the pumps are available either with a 3-way connector or with a customized cable on the right or the left side of the box

PWM cable: 2-wire cable according to customer’s specification (max length = 1m)

Generals characteristics :

> Supply voltage : 230V +10% / -15% : 50Hz ±5%

> Degree of protection IP : IP44

> Temperature class: TF95
