Product Description
Neptune Drum Mixer
The Neptune Drum Mixer provides reliable blending for chemicals and industrial liquids stored in standard 55-gallon drums. Moreover, its compact design allows operators to mix products directly inside their original container.
Neptune offers the E, F, H and HGS Series for different viscosities and operating requirements. Therefore, users can select a high-speed model for water-like liquids or a high-torque model for thicker fluids.
All Neptune drum mixer assemblies fit through the standard 2-inch or 50.8 mm opening used on 55-gallon or 208-litre drums. Consequently, installation requires minimal modification to the container.
Efficient Mixing Inside the Drum
Industrial liquids may separate, settle or lose uniformity during storage. Therefore, users often need to remix the product before transfer or dosing.
The Neptune Drum Mixer creates fluid movement throughout the container. As a result, it helps blend liquids, suspend solids and maintain a more consistent product concentration.
Moreover, direct drum mixing reduces the need to transfer material into a separate blending tank. Consequently, facilities can simplify handling while reducing product loss and contamination risks.

Together, these features support efficient blending across many industrial environments. Moreover, the different series allow users to match the mixer with the liquid viscosity and required mixing intensity.
Neptune Drum Mixer Series
E and F Series for Water-Like Liquids
The E and F Series suit low-viscosity or water-like solutions. Moreover, they use a folding 316 stainless-steel propeller that closes for drum entry and opens during operation.
The direct-drive design operates at approximately 1,750 rpm. Therefore, these models provide fast circulation for thin chemicals and readily flowing liquids.
Depending on the model, users can select electric or air-powered operation. In addition, TEFC and explosion-proof electric motor configurations are available.
H Series for Medium-Viscosity Fluids
The H Series uses a direct-drive arrangement operating at approximately 1,750 rpm. However, its blade arrangement provides greater mixing capability for thicker products.
Selected H Series models handle viscosities up to 8,000 cP. Therefore, they suit products that require more mixing force than water-like solutions.
Moreover, available motor sizes extend up to 1 horsepower. As a result, users can select the required power according to the liquid viscosity and mixing duty.
HGS Series for High-Viscosity Fluids
The HGS Series uses a rugged gear drive operating at approximately 430 rpm. Consequently, it produces higher torque at a lower mixing speed.
Selected models handle viscosities up to 32,000 cP. Therefore, the HGS Series suits extremely heavy or shear-sensitive chemicals.
In addition, the 316 stainless-steel shaft incorporates multiple mixing blades. As a result, it provides effective circulation throughout the drum while handling demanding products.
Durable Mixing Components
Neptune uses 316 stainless steel for the shaft and propeller or blade assembly. Therefore, the mixer provides good corrosion resistance with many compatible industrial liquids.
Folding propellers collapse during insertion. Afterwards, they open to their operating diameter when the mixer starts.
Consequently, operators can install the assembly through a small drum opening without removing the complete drum head.
However, users must confirm chemical compatibility before selection. In particular, corrosive concentration, fluid temperature and solids content may affect the required construction.
Electric and Air Motor Options
Electric motor options include totally enclosed fan-cooled configurations. Moreover, explosion-proof motors are available for properly classified operating areas.
Alternatively, users can select an air motor. Air-powered models provide adjustable speed and can suit facilities where compressed air is readily available.
Therefore, the correct motor depends on the available utilities, area classification and required speed control.
Neptune Drum Mixer Applications in the UAE
The Neptune Drum Mixer suits:
- Water-treatment chemical preparation
- Wastewater-treatment facilities
- Paint and coating blending
- Polymer preparation
- Textile dyes and sizing chemicals
- Adhesives and resins
- Soaps and detergents
- Industrial chemical processing
- Batch chemical preparation
- Manufacturing plants
- Stored-product remixing
- Liquid and suspended-solid blending
For example, a water-treatment facility can remix chemicals before dosing. Similarly, a paint manufacturer can restore pigment uniformity after storage.
Moreover, Neptune portable mixers can blend liquids, suspend or dissolve solids and disperse immiscible liquids. Consequently, they support many general industrial mixing processes.
Why Choose a Neptune Drum Mixer?
The Neptune Drum Mixer combines compact installation with several drive and mixing options. Therefore, it provides a practical solution for both light and demanding drum-mixing duties.
Moreover, users can select a high-speed direct-drive model or a high-torque gear-drive model. As a result, the range supports liquids from water-like chemicals to products with viscosities up to 32,000 cP.
