| Inlet Connection: |
3/4 in. NPT with 1 1/4 in. Camlock, ¾ in. BSP with 1 ¼ in. Camlock Tri-clover sanitary inlets are available. |
| Construction/Design: |
Parts are machined from 316-L stainless steel investment castings or bar stock. |
| Impeller & Final Shafts: |
For increased wear resistance, the rotor shaft is plasma-sprayed with a Chromium Oxide coating on stainless steel. |
| Bearings: |
Bearings in the rotating tee and nozzle housings are self-lubricating, carbon-fiber-reinforced polyphenylene sulfide. |
| Bearing Cups: |
Main body castings are protected by replaceable 316-L Stainless Steel cups for extended frictional wear life. |
| Static Seals: |
O-ring materials are selected for each application. Viton® is standard, with Kalrez® and EPDM available. Other materials can be supplied on special order. |
| Dynamic Seals: |
Dynamic shaft seals are spring-loaded, double-lipped and made of PTFE. They are reinforced with carbon fiber for extra-long wear and protection against leakage, abrasion and deposit build-up. |
| Nozzles: |
Dual or quad 0.05 in. (1.4 mm) to 0.225 in. (5.7 mm) orifice diameters. Other nozzle sizes available upon request. |
| Drive Mechanism: |
The wash fluid enters the Alfa Laval Gamajet at the inlet collar where it encounters and spins rotor blades. The rotor blades are attached to the top of the rotor shaft. The bottom of this shaft is connected to the inside of a sealed, 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 increase corrosion resistance. This sealed gearhead is located inside the gearbox, which itself is sealed, the output shaft are stainless steel. |
| Lubricant: |
A food-grade grease is inside the sealed gearhead casing. No customer-supplied or user-maintained lubricant is needed. |
