INTRODUCTION

The TankJet® 78 and 78D models are hydraulically driven rotating heads with nozzles ejecting streams of liquid for internal tank surfaces, cleaning, sanitizing, treating, or rinsing. The TankJet 78 model incorporates a set of bevel gears to provide a complete 360° indexing path in both planes. The index pattern will repeat every 36 revolutions. This unit is specifically designed for a minimum 5¾” dia. opening (typical for 6″ connections). Care must be exercised during insertion and retraction of this unit because of the nozzle swing span. The TankJet 78D incorporates two (2) nozzle heads, thus four (4) nozzles, and is designed for a minimum 7-5/8″ dia. openings (typical for 8″ connections). Like the TankJet 78, care must be exercised during insertion and retraction of the unit.
The unit is designed to be self-cleaning, such that it is normal for it to spray water outward from joints and pin connections. The unit may be installed on a permanent basis and is approved for Clean-in-Place (CIP) applications. However, it is strongly suggested the unit be regularly removed from service and cleaned out-of-place (COP) to remove any debris or other solids that may have collected during operation. This can be a common occurrence in systems where cleaning fluids are recirculated from the tank and back through the unit.
Many types of fluids, sanitizers, detergents, and caustics may be used through this unit to assist its cleaning effectiveness (note caution below). The cleaning efficacy of any unit is proportional to all the applicable variables, such as volume, pressure, temperature, chemicals, impingement, drainage, soils, etc.
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 federal, state, local, and facility regulations.

CONSTRUCTION:
Referring to the Parts Lists on pages 7 & 8, the TankJet 78 and 78D comprise of three basic components: the support structure, consisting of the housing, stator, seals, and stem; the drive, consisting of the rotor, bearings, and rotary housing; and the nozzle head, consisting of the hub, nozzles, stabilizing vanes, and hub cap. The units are held together through the use of retaining clips, such that it can be quickly and easily disassembled by hand.

PRINCIPLE OF ROTATION:
The liquid enters the housing cap (1) and then flows through the slots in the stator (5), causing a swirling motion in the liquid. This swirling liquid drives against the fins of the rotor (7), imparting rotation to the rotor and thus the rotary housing (12). The liquid then flows through the rotary housing and nozzle hub (16) to be distributed out each off-set nozzle (18).

CLEANING DIAMETER:
The cleaning and wetting distances are a function of rotational speed and liquid pressure applied to the unit. The TankJet 78 has an effective cleaning diameter of 45 ft. (13.7 m)

INSTALLATION

The TankJet® 78 is easy to install. Both the TankJet 78 and 78D connect to a supply tube with a simple retaining clip. There are two different size options for inlet connections to the TankJet 78 and 78D; 1-1/2″ (standard) and 2″. The supply line should be a standard smooth bore 16 gauge (.065″ thick) stainless steel tube of the appropriate size. A Ø13/64″ or Ø5mm hole should be drilled thru the supply tube according to the diagram below.

Slip the supply tube into the inlet of the unit, aligning the holes. Insert the retaining clip and swing it down until it locks. It should wrap around the neck of the inlet, but still fit loosely.
The TankJet 78 unit will only operate properly in the suspended vertical position (inlet at top), however, the TankJet 78D may be operated in any orientation.
NOTE: in order to maintain 3-A sanitary compliance, all units intended for CIP must be mounted in the suspended vertical position in order to ensure proper drainage. Other orientations must be either returned to the suspended vertical position or removed after operation and cleaned out-of-place.
