ClydeUnion S&N Pumps seawater lift submersible pumps are water and propylene glycol filled pumps specially designed to surpass the corrosive characteristics of seawater. They are precision built, hydraulically and dynamically balanced and heavy-duty seawater rated providing the offshore oil and gas industry secure, reliable and long-lasting seawater handling capability.Click for more infomation on featuresThe ClydeUnion S&N Pumps 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 zinc-free bronze with heavy-duty and high efficiency nickel-aluminium bronze impellers as a standard. Impellers are dynamically balanced to minimise vibration and maximise service life. Replaceable high class bronze or 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. Pump-grade corrosion and wear resistant stainless steel shaft is aligned with spiral fluted bushings and over dimensioned duplex for low vibrations and long life. The submersible three phase re-windable wet stator motor is wound with high-temperature resistant PE2 wiring and incorporates CoolAct Technology® - internally sealed, active circulation cooling. Cooling is guaranteed in submerged operation and does not require fluid flow past the motor in seawater up to 40° C (104° F). The pump features silicon-carbide mechanical shaft sealing and tilting axial thrust bearings that guarantee high thrust absorption.
