Project Integration

4SP2 is part of the 4SP Stainless Steel Fountain Pump range and is project-ready as a main water-supply pump for fountain systems, high-jet features, landscape ponds, recirculation basins and water shows. Best for:

Max head 336 m / Flow rate / head: 0-3 m³/h

Max head 336 m

Dải công suất motor: 0.37-3 kW / Motor power range: 0.37-3 kW

Outlet Cửa xả / Outlet: DN32/DN40; 1-1/4" / 1-1/2". For integration, SmartVision calculates required flow, total dynamic head, pipe losses, spray height, nozzle quantity, pipe diameter, check valve, debris filter, flexible coupling, cable distance and cable cross-section

Then recommends MCCB/contactor, overload, phase-loss/reverse-phase protection, water-level sensing and VFD control where flow adjustment or music-show synchronization is required.
