Hitachi’s General Features

High Quality Thrust BearingsThe thrust bearing is of the kingsbury type lubricated by the internal fluid. During operation a wedge of water is drawn between the stainless steel pivot shoes and carbon disc to carry the thrust load generated by the pump. The bearing construction is achieved long motor life because of our quality construction based on our experience and a field results.

Sand Resistant Slinger and Lip SealsA stainless steel slinger and slinger guide are also closely fit to help prevent sand entry. Double rubber seals are installed to prevent well water and contaminants from entering the motor.

Rotor Core with Baked Epoxy CoatingA baked epoxy coating prevents rusting of the rotor core. All externaland internal cast iron parts are coated with epoxy resin then bakedfor resistance to water and rust.

Highly Reliable Carbon BearingTwo water lubricated carbon bearings are used as guide bearings.These have extremely large surface area and result in extra alignmentsupport - less whipping and acts as a steady bushing.

BalancingThe rotor balance rings allow for excellent dynamic balance for the rotaring element of the motor.

Water-Filled Design The motor lubrication is provided by the internal cooling water consisting of a water, antifreeze, and antirust mixture good to – 22˚F(– 30˚C).This mixture is installed at the factory. Water plugs are located near the top of the motor and are used by the installer to check the water level or to top off if needed before installation.

Complete Corrosion and Water-Tight Protection

All main motor components are made of stainless steel: including the can housing (water tight type motors have baked epoxy coated carbon steel housings), shaft and bolts. All other motor parts are coated with the baked epoxy coating.

Japan MadeAll Hitachi submersible motors are manufactured and tested under the most stringent quality control procedures in Japan, providing long service life and trouble-free operation.

Hitachi's Special Technology

Replaceable Plug-in Type Lead The motor leads are stranded copper, extremely flexible, 150 inches (3.8m) in length and field replaceable.

Durable Insulation The motor stator coil of the canned type is mounted in a stainless steel frame and is completely sealed in a protective stainless steel cylinder. Complete water proofing insures long life for the moisture resistant insulation.

Excellent Heat Resistance Strength against thermal fluctuation and internal mechanical stress is assured by the use of a patented "Hi-canned Resin". The space between the stator, stainless steel protective can and frame is filled with this epoxy resin, allowing faster and greater heat dissipation resulting in longer motor life.

95˚F(35˚C)Water Temperature (6” 5 - 40HP)The motors operate with a flow rate 0.5ft/sec. (0.15m/sec.) in water temperature up to 95˚F (35˚C) without any derating of horsepower. This 95˚F(35˚C) temperature is 18˚F(10˚C) higher than NEMA standards.

Dual Voltage Construction (3 phase 5 - 30HP)Both constructions as single volatge and dual voltage are available.

Reliable Insulation WireThe coil conductor insulation material is a specially developed denatured polypropylene, which offers excellent leak-resistant characteristics.Three barriers are applied to the copper conductors to provide complete insulation against the cooling fluid inside the motor. This design is the result of extensive research and in long insulation life under severe operating conditions.

Quality ConstructionThe lead wires are 200 inches (5m) long and internally connected direct to the winding. The stator is enclosed by an epoxy coated carbon steel shell, and the end bells are epoxy coated cast iron. The cooling fluid in the motor is in direct contact with the insulated windings to help keep the motor cool.

2 Pole motors and 4 Pole motorsThe Hitachi submersible motor is available up to 300HP in both2 pole and 4 pole speeds. The Hitachi motor mounts to most majorpump manufactuers submersible pumps without adaption.

APPLICATION

HIGH-PERFORMANCE THRUST BEARINGThe well established KINGSBURY design thrust bearing createsa wedge of water between the pivot shoe and carbon disc. Our innovative design permits high thrust loads to be placed on the bearings while showing no measurable wear after several years of severe duty operation. This allows for long pumping life, virtual trouble free opera-tion and low maintenance. For all 6" motors, the 300lbs. maximum continuous up-thrust is absorbed between the upper carbon sleeve bearing and the rotor balance ring. For all 8" ~ 14" motors, the 1000lbs. maximum continuous up-thrust is carried between the upper slide plate and the separate up-thrust carbon bearing.

Water tight insulated wire

Water Environment

The reliability of submersible motors depends upon their insula-tion characteristics. Hitachi has carried out continuous research and development of submersible motors for many years, drawing upon its total corporate technology. These efforts have resulted in new patented water tight insulated magnet wire having excellent insula-tion characteristics. This patented technology is being applied to all Hitachi water tight submersible motors. For the insulation material, specially developed denatured polypropylene is applied over a special enamel layer. An external nylon sheath is applied over this polypropylene layer for extra mechanical protection. These three insulat ion barr iers are appl ied to copper conductors for complete insulation from the cooling fluid. This guarantees that Hitachi submersible motors will have an extremely long service life.
