GJ A8 Tank Cleaning

The Lightest, Most Powerful, Large Tank Cleaner

The E-Z8 provides the SAME flow as traditional, larger tank cleaners, but this new unit is lighter, shorter, and narrower for much easier entry and maneuverability and offers unparalleled ease of handling in a wide variety of tank cleaning applications.

Smaller in diameter than any other fluid-driven unit with similar flow characteristics the E-Z8 does not require any power assists. It fits through small openings while maintaining the flow required to clean larger vessels and its lightweight and smaller size makes it easy to move and handle.

The versatility of this machine when it comes to pressure and flow make it ideal for most large tank cleaning applications.

Construction/Design: Parts are machined from 316-L Stainless Steel investment castings or bar stock.

Impeller & Final Shafts: For increased wear resistance, the input and output shafts are plasma-sprayed with a Chromium Oxide coating on Stainless Steel.

Shaft & Gearbox Bushings: Input shaft thrust is absorbed by a Tungsten carbide bushing. Gearbox bushings are carbon-filled Teflon or other non-cupric material.

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®, Zalak® and EPDM available. Other materials can be supplied on special order.

Dynamic Seals: Rotary shaft and housing seals are spring-loaded, double-lipped and made of PTFE.
They are reinforced for extra long wear and protection against leakage, abrasion and deposit build-up.

Nozzles: Standard nozzle sizes 1/4” (6.35 mm), 9/32” (7.14 mm), 5/16” (7.94 mm), 3/8” (9.53 mm),
7/16” (11.11 mm), 1/2” (12.10 mm). Other nozzle sizes available upon request.

Drive Mechanism: The wash fluid enters at the inlet collar where it encounters and spins turbine blades. The turbine blades are attached to the top of the input shaft, the bottom of this shaft is connected to the inside of a sealed, planetary gear head which then turns the body in the horizontal plane and the nozzles in the vertical plane.

Planetary Gearhead: The sealed planetary gear head has an external casing made of steel, surface-anodized to become stainless. This sealed gear head is located inside the gearbox, which itself is sealed, and thus does not require any lubricant. All internal parts are hardened sintered steel, the end caps and output shaft are stainless steel.

Lubricant: A Food grade lubricant is inside the sealed gear head casing. No customer-supplied or user-maintained lubricant is needed.
