INTRODUCTION

The TankJet® 75 and 75H models are hydraulically driven rotating heads with nozzles ejecting streams of liquid for spanning internal tank surfaces to be cleaned, sanitized, treated, or rinsed. The TankJet 75H-2 or 75H-4 models feature an enclosed gear housing for hygienic option. Either model will provide a complete 360° indexing path in both planes, the index pattern will repeat every 45 revolutions. The TankJet 75-2 and the 75H-2 are specifically designed for 3″ dia. openings, care must be exercised during insertion and retraction of this unit because of the nozzle swing span. The TankJet 75-4 and 75H-4 incorporates 2 nozzle hubs thus 4 nozzles, and is designed for 4.2″ dia. openings. The units may be installed on a permanent basis (C.I.P.). Many types of fluids, sanitizers, detergents and caustics may be used through this unit to assist it’s cleaning effectiveness. (Please note caution below.) The cleaning effectiveness of any unit is proportional to all the applicable variables, such as volume, pressure, chemicals, impingement, drainage, soils, etc. The unit will only operate properly when mounted in the vertical position (suspended or inverted) and can clean almost any type of contained area within its range.
Caution: If chemicals, hazardous materials, operations, and equipment are used in conjunction with this cleaning equipment, it is the responsibility of the user to establish appropriate associated safety and health practices. Prior to application, the user must consult and determine the applicability of regulatory (federal, state, local and facility) safety and environmental agency limitations.

MATERIALS

• 316 Stainless Steel (UNS S31600)
• PTFE
• UHMW-PE

CONSTRUCTION

Referring to the Parts List on page 7 and 8, the unit comprises two basic components; the drive, consisting of the body, motor, rotor, and shaft; and the nozzle head, consisting of the nozzle body, bushings, nozzles, and elbow shaft.

PRINCIPLE OF ROTATION

The liquid enters the inlet cap (1) and then flows through the oblique and bypass holes in the motor (2) causing a swirling motion in the liquid. This swirling liquid goes down the outside of the vertical shaft (5) past the 6 tooth rotor (3) imparting rotation to the rotor and thus the vertical shaft. The liquid flows through the elbow shaft into the nozzle body (7), to be distributed out each off-set nozzle (12). The rotational speed of these units can be regulated through the use of various motor bypass plugs, which influences the fluid diversion to provide additional speed. Reference the Troubleshooting section and the Drawing Parts List for additional information and location.

CLEANING DIAMETER

The cleaning and wetting distances are a function of rotational speed and liquid pressure applied. The TankJet 75 has an effective cleaning diameter of 30 ft. (9.1 m).

INSTALLATION

The TankJet® 75 is easy to install as it has a single 3/4″ female pipe thread connection (NPT or BSPT) or 1″ sanitary tri-clover flange fitting. It may be installed on a tripod, a manhole cover, or suspended from a pipe. In all installations position TankJet 75 vertically upright or upside down and a suitable (200 mesh) strainer should be used to prevent dirt or scale from clogging the waterways or openings.

OPERATION

To start the unit, turn on the fluid. An in-line valve is required for a slow build-up of liquid pressure in the unit to prevent “water hammer”. To stop the unit, turn off the liquid. The unit should always be handled carefully. If the unit is dropped or maltreated it may cause internal damage to the drive pod assembly, which in turn can affect the performance of the unit.

TROUBLESHOOTING

Due to the simplicity of the unit, very few problems should occur. If any trouble should arise, the following steps may be taken: Refer to the Parts List.

• A. Check unit for external damage, look for evidence of mishandling that may have damaged shafts, bearings, or alignment.
• B. If the nozzle body fails to rotate and no liquid passes:

1. Check for liquid pressure and volume at the unit.
2. Check strainer for filter blockage.
3. Remove nozzles and check for obstructions.
4. While nozzles are off, recheck for flow through the nozzle body.

• C. If the unit fails to rotate and sufficient liquid passes:

1. Check for freedom of rotation, by hand, in the vertical and  

rotational axis.

2. If the unit is free, insert a solid motor bypass plug. The motor bypass plug port is located in the top center of the motor. The purpose of the plug is to divert the pressurized fluid to the side drive holes of the motor, thus providing more driving power to overcome any frictional build-up that may occur after extended use. If the unit still does not rotate, check for:
  *  **a.** Contamination in the unit.
  *  **b.** Wear of any one of the following parts: the bushings, washers, and the rotor.
  *  **c.** Galling and straightness of the shafts.

• D. Replace all defective parts.

WARRANTY

For newly purchased units the warranty is 18 months from the date of shipment or 12 months from the date of installation, whichever occurs first. This warranty includes manufacturing defects but does not cover the wear parts that include the bushings. This warranty will be void if parts other than those supplied by Spraying System Co. are used.
