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.

TEMPERATURES AND AMBIENT HUMIDITY

Ambient temperature
[°C]
Up to 25
Up to 30
Up to 35
Up to 40
•
Medium temperature should be higher or the same as ambient temperature, so that the
condensate does not gather on pump surface.
• Operation outside allowed conditions may shorten pump lifetime and void the warranty.
