▪ Closed industrial circulation systems
▪ Solar installations
▪ Geothermal systems
▪ Air-conditioning systems
The pumps do not fulfil the requirements of the ATEX guideline and
are not suitable for the pumping of explosive or easily flammable
fluids!
Proper intended use also includes compliance with these instruc-
tions in addition to the information and labels on the pump.
Any other use is regarded as improper use and results in the loss of
all liability claims.
Approved fluids
▪ Heating water according the requirements of accepted standards of
water quality in heating systems.
▪ Water-glycol mixture, max. mixing ratio 1:1
The pump delivery rate will be affected by the addition of glycol
due to the altered viscosity. Please take this into consideration
when adjusting the pump.
▪ Ethylene/propylene glycols with corrosion protection inhibitors.
▪ No oxygen binding agents, no chemical sealants (ensure system is
enclosed in terms of corrosion); repair leaking locations.
▪ Standard commercial corrosion protection inhibitors
rosive anodic inhibitors (under-dosing due to consumption!).
▪ Standard commercial corrosion protection inhibitors
ganic or polymer filming agents.
▪ Standard commercial cooling brines
