7. Applications
The pumps are designed to circulate hot or cold water
in residential, institutional and industrial applications:
• heating systems
• district heating plants
• central heating systems for blocks of flats
• air-conditioning systems
• cooling systems.
In addition, the pumps are used for liquid transfer and
water supply in for instance:
• washing systems
• domestic hot-water systems
• industrial systems in general.
To ensure optimum operation, the dimensioning
range of the system must fall within the performance
range of the pump.
7.1 Pumped liquids
WARNING
Contact with hazardous liquids
Death or serious personal injury
‐ If the pump is used for a liquid which is
injurious to health, it will be classified
as contaminated. In such cases, take
proper precautions to avoid injury to
health when operating or working on
the pump.
‐ Wear personal protection equipment.
The pump is suitable for thin, clean, non-aggressive
and non-flammable liquids, not containing solid
particles or fibres that may attack the pump
mechanically or chemically.
Examples:
• Central heating system water. The water must
meet the requirements of accepted standards on
water quality in heating systems.
• Cooling liquids.
• Domestic hot water.
• Industrial liquids.
• Softened water.
The pumping of liquids with a density and/or
kinematic viscosity higher than that of water will have
the following effects:
• a considerable pressure drop
• a drop in hydraulic performance
• a rise in power consumption.
In such cases, fit the pump with a bigger motor. If in
doubt, contact Grundfos.
The EPDM O-rings fitted as standard are primarily
suitable for water.
If the water contains mineral or synthetic oils or
chemicals or if other liquids than water are pumped,
chose the O-rings accordingly.
