INTRODUCTION

The TankJet® 78M is a hydraulically driven rotating head with nozzles ejecting streams of liquid for internal tank surface cleaning, sanitizing, treating, or rinsing. The TankJet 78M model incorporates a set of bevel gears to provide a complete 360° indexing path in both planes. The index pattern will repeat every 25 revolutions. This unit is specifically designed for a minimum 2.87″ opening (typically for 3″ Tri-Clamp Flange connections). Like the TankJet 78 and 78D, care must be exercised during insertion and retraction of the unit because of the nozzle swing span.

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.

TECHNICAL SPECIFICATIONS

TANKJET 78M MODELS:

*TJ78M-__-2-175-3A**

• Nozzle Orifice: 0.175″
• Operating Pressure: 25 -120 psi (1.7 ­ 8.3 bar)
• Flow Rate: 13 ­ 37 gpm (49.2 ­ 140.1 l/min)
  *Specify inlet size of ¾” or 1″.

MATERIALS:

• Stainless Steel, type 316L
• PTFE

CONSTRUCTION:

Referring to the Parts Lists on Pages 7 & 8, the TankJet 78M comprises 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, and hub cap. The unit is held together using Retaining Clips, such that it can be quickly and easily assembled and reassembled without the use of tools.

PRINCIPLE OF ROTATION:

The liquid enters the inlet (1) and then flows through the slots in the stator (3), causing a swirling motion in the liquid. This swirling liquid drives against the fins of the rotor (7), imparting rotation to the rotor (7) 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.

CLEANING DIAMETER:

The cleaning and wetting distances are a function of rotational speed and liquid pressure applied to the unit. The TankJet 78M has an effective cleaning diameter of 25ft. (7.62m)

INSTALLATION

The TankJet® 78M is easy to install. The TankJet 78M connects to a supply tube with a simple retaining clip. There are two different size options for inlet connections to the TankJet 78M; ¾” & 1″. The supply line should be standard smooth bore 16 gauge (.065″ thick) stainless steel tube of the appropriate size. A 9/64″ or 3.5mm hole should be drilled through 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 78M unit will only operate properly in the suspended vertical position (inlet at top).

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.
