The S&N Seawater Lift Submersible Pump is a preconfigured design that offers a broad range of features that save you both time and money. All pump casing parts are ZFB (Zinc-Free Bronze) with heavy-duty and high efficiency NAB (Nickel-Aluminum Bronze) impellers as a standard. Impellers are dynamically balanced to minimize vibration and maximize service life. Replaceable high class Bronze or SS (Stainless Steel) neck rings provide additional protection against wear. Dual Bronze bowl bearings are consistently lubricated by the pumped liquid, helping reduce failures and maintenance. Replaceable seal rings provide abrasion resistance between impeller and bowl. Standard pump bowls are solid ZFB with SS wear rings. Pump-grade corrosion and wear resistant SS shaft is aligned with spiral fluted bushings and over-dimensioned for low vibrations and long life. The submersible three phase rewindable wet stator motor is wound with high-temperature resistant PE2 wiring and incorporate CoolAct Technology - internal sealed, active circulation cooling. Cooling is guaranteed in submerged operation. The pump features silicon-carbide mechanical shaft sealing and Mitchell-type axial thrust bearings with tilting segments that gurantees high thrust absorption.
