Low Speed Turbines

These turbines may be used at the bottom of the mixing shaft. They have been proved to use less power than the other types of turbines. They will generate an axial flow when placed in a position one diameter from the bottom of the mixing tank. They are usually supplied with keyway and set screws. Materials are stainless types 304 or 316 with surface finish of up to 240 grits polish. Available sizes are from 2” diameter and up.

Type AFF, Model AFF3-SR-12-RC, Rubber Coated

• Axial flow, 3-blade, 12” dia.
• Stabilizer ring, welded
• Mixing shaft, welded
• Rubber coated, vulcanized process

The rubber coated turbine can withstand high corrosive products including hydrochloric acids. It is much more economical than Hastelloy. Carbon steel is easier to machine also. Sizes up to 60” in diameter may be considered for this process.

Features: OD 28”, ID 3”, blades ½” x 5” wide, ears ½” x 2”, bolts 5/8” x 2” with nuts & lock washers, SS304, finish, mill, welds ground smooth, balanced for low speed.

Options: Finish up to 240 grits, other materials available, mixing shaft available.

Applications: Easily inserted in mixing tank through manhole, hub is slipped on shaft and placed at any height, hub held on mixing shaft by compression exerted by tightening the 6 bolts on 2 sets of ears (no need of keyway or set screws)

This turbine was used to mix low viscosity products in a 55 gallon drum. The mixer was a variable low speed, post mounted, 5 HP, explosion proof, 42” rise, from our Series 4050, Model DHL-050-42/16-EX/SS.

Type DAT2, Model DAT2-6-6-SS

Anchor turbine with 2 blades and mixing shaft. Dimensions are 6.5” wide by 6” deep with 1” x 3/16” blades and 3/8” shaft. This unit has a 240 grit finish. For use on lab mixer to process viscous products that stick to wall of mixing vessel. Production units are also available with 2-blade or 3-blade configuration.

Type DEF, Model DEF3-10-4-3/8-SS, Butterfly

Turbine has 3 blades and keyless hub with set screws. Dimensions are 10” diameter, 4” wide, 3/8” thick, 5/8” ID hub. This turbine is used to process viscous products that need to be pushed down by the rotating blades. These units may be supplied in 2-blade or 3-blade configuration for lab or production applications.

Features: 11” dia., height 4”, bore ¾” with keyway, SS304, polish 240 grits, Teflon scrapers (bolted-on), suitable for flanged & dished (F&D) mixing kettle. Special Feature: Auxiliary turbine, type AFF, wmkj01ith scrapers attached at bottom of butterfly hub for mixing minute amount of powder.

Application: Slow speed mixing of powders and high viscosity pastes. Variable low speed air mixer Model DAL-100 not shown. More info on mixing kettle.
