STANDARDS AND PROTECTIONS

Pumps are manufactured according to the following standards and protections:
Protection class:
IP44
Insulation class:
180 (H}
Motor protection:
Thermal - built in
Nominal pressure:
Ego 65 PN6 and 10,
Ego 80, 100 PN6 or PN10,

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 standards, such as: 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.
Before installing the pump, the system must be subjected to a high temperature water wash (+85°C). The system must
subsequently be emptied. This operation allows to eliminate as much as possible any impurities present inside the system.
For the maintenance of a high efficiency of the system it is considered appropriate to install a magnetic dirt separator filter
to remove any residues of metallic particles, limestone, sludge and suspended deposits.
Any damage deriving from solid, fibrous or abrasive substances, not attributable to a product defect, will render the
WARRANTY NOTHING.
