Construction

Features

Plug-in type lead connection

All 6" motor leads are stranded copper, extremely flexible,
3.8m(150 inches) 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 flucuation 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.

Insulation

35°C(95°F)Water temperature(6", 5 - 40HP)

The Hitachi motors operate with a flow rate 0.15m/sec.(0.5ft/sec.) in water temperature up to 35°C(95°F) without any derating of horsepower. This 35°C(95°F) temperature is 10℃(18°F)higher than NEMA standards.

High-performance thrust bearing

The well established KINGSBURY design thrust bearing creates a wedge of water between the pivot shoe and carbon disc. Our innovative design permits hign 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 troble free operation and low maintenance. For all 6" motors, the 136kg. maximum continuous up-thrust is absorbed between the upper carbon sleeve bearing and the rotor balance ring.
