Neptune Mixers - Liquid Mixers - California

High-Performance Neptune Mixers for Reliable Industrial Agitation
Since 1961, the Neptune Mixer Company has been an essential partner for facilities requiring precision fluid handling and chemical processing. Now a premier brand within the PSG Dover portfolio, Neptune has spent decades mastering the "water-in to water-out" lifecycle, engineering equipment that thrives in the most unforgiving industrial environments. While many manufacturers provide basic motor-and-shaft setups, Neptune’s reputation is built on high-torque reliability and contamination prevention, ensuring that every industrial tank agitator delivers consistent blending power for water treatment, agricultural, and heavy chemical applications....

At Tank Depot, we recognize that a mixer is a critical safeguard for your process integrity. Neptune addresses the industry's most persistent pain point, batch contamination, through their signature grease-filled gearboxes and permanently lubricated bearings. By eliminating traditional oil seals, Neptune removes a primary failure point in sensitive mixing operations. From Bung-Entering Drum Mixers designed for 55-gallon barrels to heavy duty portable mixers capable of handling viscosities up to 25,000 cPs, our selection of Neptune products offers the durability of 316SS components and the flexibility of indexed mounting to optimize fluid dynamics for any batch size.

Industrial Applications for Neptune Mixers

Water & Wastewater Treatment:
Water & Wastewater Treatment

Neptune mixers provide the reliable agitation required for the continuous suspension of solids and the uniform dispersion of treatment chemicals across the entire "water-in to water-out" lifecycle.

Chemical Processing
Chemical Processing

Equipped with standard 316SS shafts and optional PVC or rubber coatings, these industrial tank agitators are built to withstand aggressive corrosive media while maintaining high-torque blending performance.

Paint & Coatings Manufacturing
Paint & Coatings Manufacturing

The JG Series gear-drive mixers deliver the high-torque, low-RPM performance (350–420 RPM) necessary to thoroughly mix polymers, resins, and varnishes without damaging shear-sensitive products.

Agricultural Chemigation
Agricultural Chemigation

Compact and ruggedly designed, Neptune’s portable mixers integrate seamlessly into fertilizer feed systems and irrigation skids to ensure consistent nutrient distribution for large-scale farming operations.

Committed to Water Conservation
Pharmaceutical & Soap Production

The proprietary leak-proof grease-lube design prevents process contamination, making these mixers the preferred choice for hygiene-sensitive industries where batch purity is a regulatory requirement.

IBC Tote & Drum Management
IBC Tote & Drum Management

Featuring folding propellers designed to fit through a standard 2-inch bung, Neptune’s Bung-Entering Drum Mixers enable high-efficiency blending inside closed containers without requiring lid removal or exposure to the environment.

The Neptune Advantage: Why Shop Neptune Mixing Solutions from Tank Depot

Choosing Neptune through Tank Depot means investing in a legacy of fluid-handling excellence backed by industry-leading distribution. As a single-source provider within the PSG Dover portfolio, Neptune’s engineering focuses on long-term operational efficiency, while Tank Depot ensures you get the right equipment delivered on time.

Contamination-Free
Contamination-Free

Unlike traditional oil-bathed gearboxes, Neptune’s signature grease-lube design eliminates oil seals. This prevents lubricants from leaking into your process media, a critical feature for pharmaceutical, food-grade, and high-purity chemical applications.

High-Efficiency 1.0 Ratio Propellers
High-Efficiency Propellers

Neptune utilizes square pitch 1.0 ratio marine propellers as a standard. These provide flow coefficients and power consumption characteristics that rival expensive hydrofoil designs, ensuring maximum blending efficiency for your Industrial Tank Agitators.

Precision Positioning with Indexed Mounting
Precision Positioning

Neptune’s proprietary indexed ball-and-socket mount allows for a fixed, repeatable angle of entry. This enables operators to eliminate dead zones and optimize fluid dynamics without the need for specialized tools.

Maintenance-Free Bearing Assemblies
Maintenance-Free

All mixer shaft bearings are permanently lubricated, significantly reducing total cost of ownership and preventing the mechanical failures common in low-tier Portable Tank Mixers.

Unmatched Inventory & Distribution
Unmatched Inventory & Distribution

We facilitate access to Neptune’s full suite of container-specific agitation tools, including Bung-Entering Drum Mixers with folding 316SS propellers and IBC Tote Mixers available in both gear-drive and direct-drive configurations.
