GJ 9.2

Inlet Connection:

¾ in. NPT-Female, ¾ in. BSP-Female

Construction/Design:

Parts are machined from 316-L stainless steel investment castings or bar stock.

Impeller & Final Shaft:

For increased wear resistance, the input shaft is plasma-sprayed with a Chromium Oxide coating on stainless steel.

Shaft & Gearbox Bushings:

Turbine shaft thrust is absorbed by a Tungsten carbide bushing. Gear bushings are carbon filled polyphenylene sulfide.

Static Seals:

O-Ring materials are selected for each application. Viton is standard, with Kalrez available. Other materials can be supplied on special order.

Dynamic Seals and Bearings:

Rotary shaft and housing seals/bearings are made from carbon-filled-reinforced polyphenylene sulfide for extra long wear and protection against leakage, abrasion and deposit build-up.

Nozzles:

Nozzle sizes from 0.1 in. (2.5 mm) to 0.2 in. (5 mm)

Drive Mechanism:

The wash fluid enters the Alfa Laval Gamajet at the inlet collar where it encounters and spins turbine blades. The turbine blades are attached to the top of the drive or rotor shaft. The bottom of this shaft is connected to the inside of a sealed, robust planetary gearhead which then turns the body in the horizontal plane and the nozzles in the vertical plane.

Planetary Gearhead:

The sealed planetary gearhead has an external casing made of steel, surface-anodized to become stainless. This sealed gearhead is located inside the gearbox, which itself is sealed, and thus does not require any lubricant. All internal gearhead parts are hardened sintered steel.

Lubricant:

Food-grade grease is inside the sealed gearhead casing.
