UET offers two optional high tech impeller configurations designed to maximize operating efficiencies in virtually any mixing application.

F4 HYDROFOIL

The F4 Hydrofoil impeller provides approximately 200% more pumping capacity than a conventional 45 degree pitch impeller. This added mixing capacity is achieved without additional horsepower or the cost of additional mechanical equipment.

The following table compares the pumping capacity of the Hydrofoil to a conventional 45 degree pitch blade turbine at nominal horsepower draws and an operating speed of 84 RPM.

 

Nominal Horsepower Draw	Impeller Diameter for Conventional 45° Pitch Blades	Mixer Flow per Impeller (GPM) 45° Pitch Blades	Equivalent Impeller Diameter for Foil	High Efficiency Foil Flow per Impeller (GPM)	Increased Mixing due to Foil
1	26"	5,630	41"	12,530	222%
3	33"	11,500	53"	27,066	235%
5	37"	16,200	59"	37,338	230%
7.5	40"	20,500	64"	47,657	232%
10	42"	27,775	67"	54,677	229%
15	46"	31,250	74"	73,667	235%
25	51"	42,590	82"	100,234	235%
40	56"	56,365	90"	132,525	235%
50	58"	62,580	93"	146,224	233%

MB/A ADJUSTABLE PITCH IMPELLER

The extremely versatile MB/A mixing impeller features multiple configurations using 2 to 8 blades and in-field pitch adjustability to fine tune pumping and shear requirements.

Each blade can be individually pitched from 0 to 180 degrees.

The MB/A impeller can be easily adjusted in the field to handle a wide range of applications such as solids suspension, gas dispersion, viscous fluids, heat transfer, flocculation, and blending.

TYPE 7700 Double Seal Cartridge
For Top Entry Mixer Applications

The Type 7700 mechanical seal is used for heavy duty mixer applications and isolation of process batches from contamination.

The heavy duty Type 7700 seal is design-specific to serve critically important vessels in batch or continuous processes. It guards the batch from contamination, greatly reduces leakage, and extends mean time between planned maintenance.  For performance and durability, this dry-running, or wet, double opposed cartridge seal is in a class by itself.  It runs cooler and quieter, has better balance and can handle more shaft movement/displacement than any other heavy duty mixer seal.  It can operate as a full contact dry-running seal, eliminating need for buffer fluid, or it can run with liquid lubrication.  Type 7700 seals are available in sizes from 1" through 8" or larger.

Operating Conditions

• Temperatures: Up to 300°F (150°C)

TYPE 37FS FULLY SPLIT SEAL

The Type 37FS seal is used for pulp and paper, petrochemical, power plants, food processing, municipal wastewater, and other demanding applications where downtime must be kept to a minimum.

Operating Conditions

• Temperatures: Up to 300°F (150°C)

• Pressures: Full vacuum to 300 psig (21 bar g)

• Speeds: Up to 300 rpm. (okay)
