Q-P and Q-H Curves
Why the 4SP14 is used for large projects?
Material, Impeller, and Configuration Options
High flow rates increase internal torque and hydraulic pressure. The 4SP14 fountain pump is reinforced to handle these loads, reducing vibration and preventing mechanical fatigue.
SS316 option for corrosive water
SS316 available. Prevents pitting. 10+ year life.
Wide-passage impellers for debris resistance
Wide-passage impellers. Resists debris. For open-water basins or reservoirs.
Parallel operation for synchronized fountains
Parallel operation. Multiple pumps work together for large musical fountains.
Large-Volume fountain pump Use Cases
Commercial and musical fountains
Powers large-diameter central jets and water walls in public plazas. The pump delivers high flow to maintain tall, stable water columns and even water distribution across vertical walls. For musical fountains, it supports rapid start-stop cycles and VFD control without pressure loss.
Industrial cooling and water supply
Moves water for factory processes and HVAC cooling towers. The pump supplies consistent flow to heat exchangers, condensers, and process equipment. For cooling towers, it maintains circulation through distribution headers and fill media, enabling stable heat rejection.
Agricultural irrigation
Fills reservoirs and powers sprinkler arrays. The pump transfers water from wells or storage tanks to field reservoirs, reducing fill time. It also provides pressurized flow to sprinkler heads, pivot systems, or drip lines, covering large crop areas with uniform distribution.
