Applications
The pumps are designed to circulate hot or cold water
in residential, institutional and industrial applications
in systems, such as:
• heating systems
• district heating plants
• central heating systems for blocks of flats
• air-conditioning systems
• cooling systems.
In addition, the pump range is used for liquid transfer
and water supply in systems such as:
• washing systems
• hot water recirculation systems
• industrial systems in general.
To ensure optimum operation, the dimensioning
range of the system must fall within the performance
range of the pump.
2.3.1 Pumped liquids
TP, TPD pumps are suitable for thin, clean, non-
aggressive and non-explosive liquids without 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
• hot tap 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, the pump must be fitted 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/synthetic oils or
chemicals or if other liquids than water are pumped,
the O-rings must be chosen accordingly.
