SM 4

Typical Applications

• Domestic andcommercialpressureboosting where high head is required at modest flow.
• Packaged booster sets serving multi-storey buildings and high-rise risers.
• Water supply from storage tanks to distribution networks and header tanks.
• Sprinkler and drip irrigation systems requiring sustained pressure.
• Washing and cleaningplant, andgeneral industrial water transfer.

Operating Conditions

• Clean water,non-flammable andnon-explosive, free of solid particles and fibres.
• Liquid temperature to +60 C; maximum ambient temperature +40 C.
• Non-self-priming: the pump must be fully primed before starting.
• Keep the suction line short, airtight and fully flooded to avoid cavitation.
• Motor totally enclosed, fan-cooled, protection IP44 to IP55, insulation class B.
• All models in this series have 4 stages; the figure after the oblique is the pump frame size, which sets the flow range.
• Do notrun dry;a low-levelor flowswitchis recommended on tank-fed installations.
