Product Overview

MAJOR CASTING MATERIALS

The impeller, casing, bearing/seal housing and motor cover shall be of ASTM A48 Class 30 high quality cast iron for

strength and long life. Bronze impeller shall be cast iron from ASTM B584 UNS C87600 when ordered as an option.

CORROSION PROTECTION

The pump/motor shaft wetted-end shall be 316SS extension fusion welded to motor shaft of carbon steel. Both inner

and outer surfaces of cast iron shall be electrocoat-painted with thermo-setting Acrylic Enamel baked at 400º F., after

castings are completely machined.

MOTOR

The integral motor shall be completely sealed from the environment by use of circular cross section o-rings accurately

tted into machined grooves which shall provide designed compression of metal to metal ts. Designs which require

a specic torque on the casing bolts or which require rectangular gaskets or sealing rings shall not be allowed. The

motor shall be rated for continuous duty under full nameplate load while at full submergence in the station. The mo-

tor shall be provided at the specic site conditions of 115, 208 or 230 V, single phase or 200, 230, 460 or 575 V, three

phase as required, all shall be at 60 Hz. Single phase motors shall be capacitor-start. All single phase motors shall be

provided with thermal protection. Single phase motors shall have an on winding sensor with automatic reset. Three

phase motors shall be protected by ambient compensated quick-trip heaters, or, adjustable motor circuit protectors

provided in control. The stator winding shall be open type with class B insulation suitable for operation in clean dielec-

tric oil for efcient heat transfer and lubrication of the ball bearings. The stator shall be a register t into the bearing

housing to ensure positive alignment, and bolted for ease of serviceability. The motor shall be provided with ball type

anti-friction bearings which shall support the heavy duty rotor shaft and to handle all radial and axial loads imposed by

the impeller while limiting shaft deection at the mechanical seal faces. Sleeve type bearings shall not be considered

equal and, therefore, shall not be allowed. The ball bearings shall be designed for a B-10 life of 30,000 hours mini-

mum. The motor shall be designed and tested to withstand an 18 day locked-rotor operation without damage.

POWER CABLE

The power cable shall be sealed at the motor end as it enters the motor casing by a two part barrier to moisture intru-

sion. The rst line of defense shall be the compression of the oil and chemical resistant grommet which shall seal the

outer jacket of the power cord. In the event that the outer jacket of the power cord should become damaged, then the

second line of defense shall be the epoxy poured isolated conductors within the jacketed cable itself. The insulation

shall be removed from the individual conductors and the epoxy shall be allowed to form a leak-proof seal against wick-

ing of the power cable between the outer jacket and the insulation of the individual conductors. The outer jacket of the

power cord shall be oil resistant and water resistant. The power cable shall be rated for NEC severe service “S”, type

“SJTOW” or “STOW”.
