Jensen Series 600 Mixers
Fixed-Angle & Vari-Angle · Directive 2014/34/EU · Certificate No.: ITS15ATEX8298X Issue 0
The Jensen Series 600 Mixer is the only side-entering mixer designed exclusively for use in petroleum service. Every design feature is tailored to meet the rugged requirements of refinery and pipeline applications.
In every configuration range it offers superior life and load figures, unmatched ease of maintenance, and outstanding mixing efficiency. The Series 600 is supported entirely by the tank man-way or nozzle — no tie rods, braces, or other external supports are required.

Standard Materials of Construction
Jensen standard materials offer optimum performance in any hydrocarbon application.
| Component | Material |
|---|---|
| Shaft | Stainless Steel |
| Locking Ring, Lock Bushing & Seal Housing | 316 Stainless Steel |
| Drive Yoke | Aluminum Bronze |
| Propeller & Body | Cast Carbon Steel |
| Gearbox | 356-T6 Heat Treated Aluminum Alloy |
| O-Rings | Viton "A" |
The Tungsten Carbide coated wear sleeve provides maximum protection to the mixer shaft. Tungsten Carbide contact surfaces of the end bearing and wear sleeve assure long life and superior wear characteristics.
Gearbox Features
Mechanical Seal — Type F
The Jensen Type "F" mechanical seal is an integral part of every Series 600 Mixer. It is designed for long life at low cost. Materials of construction are selected to suit petroleum applications. Both sealing members are extra heavy to prevent face distortion. If seal replacement is necessary, wearing parts may be purchased separately, cutting replacement cost in half.
| Component | Material |
|---|---|
| Rotating Seal Face | Carbon |
| Stationary Seal Face | Ni-Resist 2 (High Nickel Cast Iron) |
| Sleeve | 316 Stainless Steel |
| O-Rings | Viton "A" |
| Springs | Inconel |
Seal Replacement Procedure
- Remove yoke bolts and bearing cap.
- Pull shaft back and rotate ¼ turn counter clockwise until lock engages and shaft stops.
- Remove the shaft bolt, thrust bearing assembly, and the key and yoke.
- Remove the seal by carefully sliding it off the shaft.
- True cartridge design simplifies removal and ensures positive seal face protection during change-out.

Mixer Selection
FA — Fixed Angle
For companies blending two or more fluids. Select the Jensen Model 600 Fixed-Angle Mixer for blending, heat transfer, and homogenization applications.
VA — Vari-Angle
For companies needing to remove sediment accumulations from tank bottoms. In cases where both blending and bottom suspension are required, the Vari-Angle should be selected.
Coupling Features
The design simplicity of the Jensen non-lubricated coupling guarantees maximum life even under the most severe conditions. The tough, multi-ply flexible nylon and rubber element permits angular and parallel misalignment in excess of other couplings. Removal of the driver gearbox or flexible element can be accomplished without moving hubs on their shaft.
The flexible "Tors" element is a patented product of The Falk Corporation.
Vari-Angle Features
The Jensen Vari-Angle mixer features a precision, ball-type stuffing box allowing up to 60 degrees of angular movement. Sealing of the VA ball is accomplished by Jensen's innovative ferrule seal backed by Teflon impregnated non-asbestos packing which is fully adjustable, eliminating leaks. Mixer weight is supported entirely by two heavy-duty, pin-type hinges.
Propeller Roll-Through Clearances (inches)
Jensen Pitch-Adjusted propellers can be installed through most standard manways without removing the mixer shaft or entering the tank. Manway Depth (H) vs. propeller diameter.
