3 – Discharge Bearing – Extra long top protected bronze bearing insures positive shaft alignment and stabilization for extended life.
4 – Intermediate Bowl – Close grained Class 30 cast iron. Water passage glassed for maximum efficiency and abrasion resistance.
5 – Impellers – Designed for maximum efficiency with wide rangehydraulic coverage. Precision balanced for smooth operation.
6 – Upthrust Collar – Designed for extra margin of safety against possible momentary upthrust occurring at startup.
7 – Intermediate Bowl Bearings – Reliable long life bronze or rubber bearing.
8 – Lock Collets – Accurately machined to insure positive locking of impeller to pump shaft.
9 – Pump Shaft – 100,000 PSI high tensile stainless steel provides strength and excellent corrosion resistance. Ground and polished for smooth bearing surface.
10 – Suction Inlet – Contoured for smooth flow entrance. Protected by an oversized stainless steel strainer to prevent entrance of damaging solids.
11 – Suction Adapter – Ductile iron provides for increased strength and positive motor alignment. Open area permits easy access to pump/motor coupling.
12 – Pump/Motor Coupling – Large stainless steel coupling accurately machined for perfect alignment, balance and power transmission. Submersible pumps and motors provide an extensive list of options versus other deep well pumping equipment systems. Advanced engineering designs and experience now assure units for long term pumping service. Water well applications provide the perfect opportunity to evaluate features and benefits of submersible equipment.
Motor Options
Hermetically Sealed Type
A Hermetically Sealed Type motor utilizes windings of standard construction and insulation thickness. The windings are encased and Hermetically Sealed within the external shell casing on the outside and an internal tube or liner inside the bore. The Hermetically Sealed enclosure eliminates the possibility of water leakage into the winding the liquid medium circulates between the rotor and stator liner providing lubrication and cooling to the bearings.
Wet Winding Type
Wet Winding Type motor is one in whichthe motor windings are in direct contact with a liquid medium. The medium is clean, clear water. A pressure balancing systemprevents exchange of the motor liquid mediumand well water due to thermal expansionand contraction when the motor is operating. The liquid medium fills the inside of the motor and surrounds both the stator windings and the rotor. A completely water proof insulation is used on the magnet wire used for the stator windings. The liquid medium inside the motor air gap and coils acts as a heat transfer device by circulating through the windings and transferring heat to the external casing. Dissipation of this heat occurs as the well water flows at a required velocity over the external case. As is the case in all submersible type motors, the internal liquid medium is also used for bearing lubrication.
