5.2 Technical data
Maximum utilisation pressure
Pump housing 16, 25 or 30 bar depending on the model
Maximum suction pressure
10 bar
Notice: the actual input pressure (P input) + the pressure at zero delivery
rate (P zero delivery rate) must always be lower than the maximum au -
thorised operating pressure (P max). If the maximum authorised operat -
ing pressure is exceeded, the mechanical seal and the roller bearing can
be damaged or their life span reduced.
P input + P zero delivery rate ≤ Pmax
Refer to the pump plate for the maximum operating pressure: Pmax

(*)
• Residential emission –
1st environment: PN-EN 61800-3
• Industrial interference resistance –
2nd environment: PN-EN 61800-3
(*) In the frequency range between 600 MHz and 1 GHz,
the display or the pressure indication in the display
might be disturbed in the exceptional case of the direct
vicinity (<1 m from the electronic module) of radio
transmission installations, transmitters or similar devic-
es working in this frequency range. The operation of the
pump is not affected at any time.
