• protection against dry running, overheating, freezing, blocking, cycling and abnormal current or voltage
• esy I/O module (accessory) for connection to a building management system (BMS)

Operating conditions

Clean, non-viscous, non-aggressive and chemically neutral water without solid or abrasive particles up to +50 °C, ambient up to +55 °C, inlet pressure max. 5 bar, nominal pressure PN 12. The pump is not self-priming – it draws from a tank or boosts the pressure of a mains supply; when installed above the water level, the suction lift with a foot valve is max. 4 m. Fixed installation in vertical position, motor protection IPX5, insulation class F. WRAS, ACS and NSF61 certificates make it suitable for drinking water as well.

Have the electrical connection and commissioning carried out by a qualified professional; the supply must be protected by a residual current device with I Δn ≤ 30 mA.
