2. General information

The Grundfos MAGNA1 is a complete range of circulator pumps with integrated controller enabling adjustment of pump performance to the actual system requirements. In many systems, this will reduce the power consumption considerably, reduce noise from thermostatic radiator valves and similar fittings and improve the control of the system.

The desired head can be set on the pump control panel.

2.1 Applications

The Grundfos MAGNA1 is designed for circulating liquids in the following systems:

• heating systems

• air-conditioning and cooling systems.

The pump can also be used in the following systems:

• ground source heat pump systems

• solar-heating systems.

2.2 Pumped liquids

The pump is suitable for thin, clean, non-aggressive and non-explosive liquids, not containing solid particles or fibres that may attack the pump mechanically or chemically.

In heating systems, the water should meet the requirements of accepted standards on water quality in heating systems, for example the German standard VDI 2035.

2.2.1 Glycol

The pump can be used for pumping water/glycol mixtures up to

50 %.

Example of a water/ethylene glycol mixture:

Maximum viscosity: 50 cSt ~ 50 % water/50 % ethylene glycol mixture at -10 °C.

The pump has a power-limiting function that protects against overload.

The pumping of glycol mixtures will affect the max. curve and reduce the performance, depending on the water/ethylene glycol mixture and the liquid temperature.

To prevent the ethylene glycol mixture from degrading, avoid temperatures exceeding the rated liquid temperature and minimise the operating time at high temperatures.

It is important to clean and flush the system before the ethylene glycol mixture is added.

To prevent corrosion or lime precipitation, check and maintain the ethylene glycol mixture regularly. If further dilution of the supplied ethylene glycol is required, follow the glycol supplier's instructions.

Note

Additives with a density and/or kinematic viscosity higher than those/that of water will reduce the hydraulic performance.

Warning

Do not use the pump for flammable liquids, such as diesel oil and petrol.

Warning

Do not use the pump for aggressive liquids, such as acids and seawater.

2.5 Insulating shells

Insulating shells are available for single-head pumps only.

Note

Limit the heat loss from the pump housing and pipework.

The heat loss from the pump and pipework can be reduced by

insulating the pump housing and the pipework. See fig. 4.

• Insulating shells for pumps in heating systems are supplied with the pump.

• Insulating shells for pumps in air-conditioning and cooling systems (down to -10 °C) are available as accessories and

must be ordered separately. See section 11.1 Insulating kits for air-conditioning and cooling systems

.

The fitting of insulating shells will increase the pump dimensions.

Note

Pumps for heating systems are factory-fitted with insulating shells. Remove the insulating shells before installing the pump.

Fig. 3 Operating conditions

2.3.1 Liquid temperature

See fig. 3, pos. 1.

Continuously: -10 to +110 °C.

2.3.2 System pressure

See fig. 3, pos. 2.

The maximum permissible system pressure is stated on the pump nameplate. See fig. 6.

2.3.3 Test pressure

The pumps can withstand test pressures as indicated in

EN 60335-2-51. See below.

• PN 6: 7.2 bar

• PN 10: 12 bar

• PN 6/10: 12 bar

• PN 16: 19.2 bar.

During normal operation, the pump should not be used at higher pressures than those stated on the nameplate. See fig. 6.

Pumps tested with water containing anti-corrosive additives are taped on the suction and discharge ports to prevent residual test water from leaking into the packaging. Remove the tape before installing the pump.

The pressure test has been made with water containing anti-corrosive additives at a temperature of +20 °C.

2.3.4 Ambient temperature

See fig. 3, pos. 3.

0 to +40 °C.

The control box is air-cooled. Therefore, it is important that the maximum permissible ambient temperature is not exceeded during operation.

During transport: -30 to +55 °C.

2.3.5 Sound pressure level

See fig. 3, pos. 4.

The sound pressure level of the pump is lower than 43 dB(A).

2.4 Frost protection

Caution

Note

If the pump is not used during periods of frost, necessary steps must be taken to prevent frost bursts.

Additives with a density and/or kinematic viscosity higher than those/that of water will reduce the hydraulic performance.

Fig. 4 Insulating shells

2.6 Non-return valve

If a non-return valve is fitted in the pipe system (fig. 5), ensure

that the set minimum discharge pressure of the pump is always higher than the closing pressure of the valve. This is especially important in proportional-pressure control mode (reduced head at low flow). The first non-return valve is included in the pump setting as the minimum setpoint is 1.0 metre.

3.1 Lifting the pump

Warning

Observe local regulations setting limits for manual lifting or handling.

Always lift directly on the pump head or the cooling fins when

handling the pump. See fig. 8.

For large pumps, it may be ncessary to use lifting equipment.

Position the lifting straps as illustrated in fig. 8.

3.2 Installing the pump

The MAGNA1 is designed for indoor installation.

The MAGNA1 pump range includes both flanged and threaded versions. These installation and operating instructions apply to both versions, but give a general description of flanged versions.

If the versions differ, the threaded version will be described separately.

The pump must be installed in such a way that it is not stressed by the pipework. The maximum permissible forces and moments from pipe connections acting on the pump flanges or threaded

connections can be found on page 34.

The pump may be suspended direct in the pipes, provided that the pipework can support the pump.

Twin-head pumps are prepared for installation on a mounting bracket or base plate (pump housing with M12 thread).

To ensure adequate cooling of motor and electronics, observe the following requirements:

• Position the pump in such a way that sufficient cooling is ensured.

• The ambient temperature must not exceed +40 °C.

Step Action Illustration

System application

In systems with relatively large pressure losses in the distribution pipes and in air-conditioning and cooling systems.

• Two-pipe heating systems with thermostatic valves and

– very long distribution pipes

– strongly throttled pipe balancing valves

– differential-pressure regulators

– large pressure losses in those parts of the system through which the total quantity of water flows

(for example boiler, heat exchanger and distribution pipe up to the first branching).

• Primary circuit pumps in systems with large pressure losses in the primary circuit.

• Air-conditioning systems with

– heat exchangers (fan coils)

– cooling ceilings

– cooling surfaces.

In systems with relatively small pressure losses in the distribution pipes.

• Two-pipe heating systems with thermostatic valves and

– dimensioned for natural circulation

– small pressure losses in those parts of the system through which the total quantity of water flows

(for example boiler, heat exchanger and distribution pipe up to the first branching) or

– modified to a high differential temperature between flow pipe and return pipe

(for example district heating).

• Underfloor heating systems with thermostatic valves.

• One-pipe heating systems with thermostatic valves or pipe balancing valves.

• Primary circuit pumps in systems with small pressure losses in the primary circuit.

The pump can also be set to operate according to the max. or min. curve, like an uncontrolled pump:

• The max. curve mode can be used in periods in which a maximum flow is required. This operating mode is for instance suitable for hot-water priority.

• The min. curve mode can be used in periods in which a minimum flow is required. This operating mode is for instance suitable for manual night setback.

In the case of twin-head operation, the required relative inlet pressure must be increased by 0.1 bar / 0.01 MPa compared to the stated values for single-head pumps or twin-head pumps in single-head operation.

Note

The actual inlet pressure plus pump pressure against a closed valve must be lower than the maximum permissible system pressure.

The relative minimum inlet pressures apply to pumps installed up to 300 metres above sea level. For altitudes above 300 metres, the required relative inlet pressure must be increased by

0.01 bar / 0.001 MPa per 100 metres altitude. The MAGNA1 pump is only approved for an altitude of 2000 metres above sea level.

EMC (electromagnetic compatibility)

EN 55014-1:2006, EN 55014-2:1998, EN 61800-3-3:2008 and

EN 61000-3-2:2006.

Sound pressure level

The sound pressure level of the pump is lower than 43 dB(A).

Leakage current

The pump mains filter will cause a discharge current to earth during operation. I leakage

< 3.5 mA.

Power factor

The MAGNA1 has a built-in PFC (Power Factor Control) which gives a cos φ from 0.98 to 0.99, i.e. very close to 1.
