PUMP MEDIUM

Pump medium can be pure water or a mixture of pure water and glycol, which is appropriate for central heating
system. Water must meet water quality standard VDI 2035. The medium must be free from aggressive or explosive
additives, free from mixtures of mineral oils and solid or fibrous particles. The pump should not be used for pumping
flammable, explosive media and in an explosive atmosphere. Permanent magnet rotor inside the pump is prone to
accumulating magnetic particles on its surface, which can lead to abrasion of bearings and rotor can or even blocking
the rotor. Although the pump is built in a way that the effect of magnetic particles is minimal, failures of bearings,
rotor cans and blocked rotors are not a subject of claims.
To improve pump resistance to magnetite we recommend the use of magnetite filter.


Medium temperature should be higher or the same as ambient temperature, so that the
condensate does not gather on pump surface.

Operation outside recommended conditions may shorten pump lifetime and void the
warranty.
