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.
