Blue Mule Professional Cleaning Systems

Thank you for your interest in our equipment! Since 2012, Blue Mule has been the online retail brand of the industrial manufacturing company, Lafferty Equipment. Blue Mule facilitated the purchase of some of our most popular chemical dilution and dispensing systems.

We are pleased to now offer online ordering directly through Lafferty Equipment.

While Lafferty and Blue Mule always operated as one company behind the scenes as the original manufacturer, Blue Mule customers will now enjoy access to the full Lafferty product range and customer service team. The products themselves and prices remain the same, although some are referred to by different descriptions (names) and part numbers.

Blue Mule will stop accepting new orders in December 2022, and all operations will transition to Lafferty. Existing Blue Mule website orders will process normally, and product warranties are unaffected.

Same designs, different name!

Hose-End Foamers & Sprayers

Hose-End Foamers and Sprayers (also known as Foam-Alls and Spray-Alls) combine a chemical injector and nozzle/wand into a heavy-duty machined polypropylene assembly.  Simply connect the unit to the end of a water hose, set the dilution ratio using the included color-coded metering tips, and start cleaning!

These easy-to-use chemical dilution and application systems are great for everything from washing cars to disinfecting animal care facilities.

Lafferty machined polypropylene injector bodies and stainless steel fittings offer superior durability and performance compared to molded plastic alternatives.

“Compact” models draw chemical from an attached bottle. Other configurations include a suction tube to draw chemical from any user-supplied container.

Use a Foamer to dilute and apply foaming chemicals or Sprayer for non-foaming products.  Foam is great for many reasons, but sprayers can cover a wider area and shoot further – so the best choice depends on your goals.

Most configurations feature a choice of flow rates. When choosing a model, consider the desired coverage speed versus the rate of chemical usage.

Stainless steel ball valve activation is offered for extra durability in demanding environments.

Complete Wall-Mounted Systems

Complete Wall-Mounted Systems include a heavy-duty machined chemical injector, discharge hose, and paired nozzle or foam wand.  Safety and ease-of-use are enhanced because the user doesn’t need to transfer or carry chemical. Simply connect the system to a water supply, set the dilution ratio(s) using the included metering tips, and start cleaning!

Most wall-mounted units are available in a portable configuration.

Consider installing wall-mounted units in areas that require frequent cleaning. It is easy to use and offers long-term cost advantages compared to hose-end style equipment.

Choose a model based on the desired flow rate and coverage, and whether you wish to apply foam or liquid spray.  Some systems are specialized for animal bathing, but Blue Mule foaming and spraying equipment can be used with any liquid chemical product.

Lafferty “Uni-Body” Systems™ dilute chemical on demand using city water pressure (35-125 PSI) using a durable, chemical-resistant, machined polypropylene body. These systems are designed with cost-effectiveness in mind, and similar units are available with stainless steel mounting brackets for exceptionally demanding environments.

Uni-Body Spray-Alls dilute chemical and project liquid spray in a fan pattern and are typically used to apply non-foaming chemicals.

Similar to the Compact Sprayers, above, choose a model based on the desired output volume (w-20, W-50, etc.)

Uni-Body Airless Foamers dilute chemical and create wet, clinging foam without compressed air. They are used with foaming disinfectants, degreasers, or any cleaning detergent (soap).

#975075 Uni-Body A-25 Airless Foamer is suitable for most situations.

Airless Brush Foamers dilute concentrated chemical on demand using water pressure.  Then, the diluted solution flows through the foamer body that draws in atmospheric air to create the optimal volume of wet, clinging foam.  No compressed air required. Available with a soft or stiff bristle brush for tasks that require a soft touch or hard scrubbing.

Lafferty also offers Brush Foamers that utilize compressed air to create richer foam.

Got an air compressor?

Compressed-Air-Assisted Foamers also dilute chemical on demand, but inject compressed air into the solution. Air-assisted foam clings better than airless foam and the foam consistency (wet/dry) is adjustable. Learn more with our Foam Cleaning Overview.

#975545-G Uni-Body LV Foamer is a low volume foamer (0.65 GPM @ 40 PSI) but it’s perfectly capable of foaming larger areas. The low compressed air requirement of 1.25 CFM means it can be powered by a smaller consumer-grade air compressor.

Mixing Stations (Proportioning Dispensers)

Ball Valve Mixing Station
Push Lever Mixing Station

Mixing Stations (Proportioning Dispensers) dilute concentrated chemical on demand using water pressure and dispense into any size container. They are the heart of any chemical management program.

Mixing Stations with more than one valve dilute multiple chemicals (disinfectant, floor cleaner, degreaser, window cleaner, etc.) or dilute the same chemical to several different ratios (daily use, extra strength, etc.)

Lafferty offers models with ball valve or push lever activation, to prevent the unit from running unattended.

Select Lafferty Mixing Stations are certified to meet ASSE 1055, which is a widely-recognized standard for chemical dilution devices with an integral method of backflow prevention.

Level Master

In addition to manually activated mixing stations, Lafferty also offers Level Masters, which are float valve activated proportioners that maintain a day tank of ready-to-use chemical solution.

Pump-Up Foamers (Foam-Alls)


Pump-Up Foamers project a low volume of rich, clinging foam.  They are ideal for precise application and when portability is required.

Simply fill with pre-diluted (ready-to-use) foaming chemical from a Mixing Station, pressurize the tank, and start cleaning!

Lafferty also offers Pump-Up Sprayers for non-foaming chemicals.

Add -E to the end of the Lafferty part number for factory-installed EPDM seals (Viton/Nitrile standard).

Fogging Systems

Foggers (also called Misters) atomize and project ready-to-use chemical using compressed air.

Damp fog (mist) fills the air and covers exposed surfaces with chemical, including hard-to-reach areas.  Metering tips can reduce chemical usage rate and output wetness.

Choose a model based on the size of the area involved and the available compressed air. The Fogger Series Comparison provides a summary of utility requirements and performance.

“Compact” Foggers (AKA Fog Guns) feature an attached chemical container and connect to a compressed air line.

Pressure Washer Equipment

Pressure washer foamers and sprayers dilute chemical on demand using a chemical injector and apply it with a paired spray nozzle and/or foam wand.  These industrial-grade pressure washer attachments feature machined stainless steel bodies for long life and low maintenance.

Hose-End and “Compact” units dilute chemical concentrate from an attached bottle or bulk container near the gun.  This configuration is incredibly versatile and the easiest way to start cleaning.

“Combo” kits feature an injector that is typically installed at or near the pressure washer, to avoid carrying chemical, and include nozzles to foam or spray.  Choose Model 10 or Model 20 based on the GPM of your pressure washer (details at links below).

Animal Bathing Systems

Bathing systems for professional groomers and pet owners

Blue Mule bathing systems save time and money by accurately diluting concentrated products (shampoo, conditioner, etc.) and applying directly on to the animal as liquid spray or foamy lather, depending on whether a spray nozzle or foam wand is being used.

Simply connect to 40+ PSI water pressure, set your dilutions with color-coded metering tips, and start washing.

“City” water pressure is typically suitable, but can vary between locations, and even between faucets in a building – so our systems include a water pressure gauge to validate. Adjust metering tips if you find you’re using too much or too little shampoo.

Our heavy-duty, low-maintenance, and easy-to-use equipment will outperform and outlast the competition through superior design and materials. Our polypropylene injector bodies are machined in house before being assembled and tested – all in the USA.

Dilution and application systems are available to address almost any situation – from washing tiny kittens to horses!

Any single-function Lafferty Foamer or Sprayer can apply shampoo products, but Blue Mule “Ultimate Wash Systems” include a rinse mode and special nozzles.

Core Bathing Systems

These versatile systems feature a water flow rate of 2.3 GPM @ 40 PSI while applying product and include a rinse mode. These systems are available with 2, 6, or 8 suction tubes for multiple unique products and/or different dilution ratios of the same products.

Ultimate Wash System 6

5-Hole Spray Nozzle
A-50 Airless Foam Wand

The unique 5-hole nozzle creates a fur penetrating spray and is interchangeable with an optional airless foam wand, which creates a foamy lather. A foam wand is optional for the Ultimate Wash System 2 and 6, and is included standard with the Ultimate Wash System 8.

Ultimate Wash System 4 can apply product quickly or slowly (two flow rates).

Shown in video: Ultimate Wash System 2 (2.3 GPM @ 40 PSI) with extended-length hose run through an over-the-head wash arm. Our standard equine bathing systems, Ultimate Wash Systems 1 and 4, feature slightly-lower-volume product application modes to reduce runoff (1.25 GPM @ 40 PSI).

Lawn & Garden Sprayers

Fertilizers and broad-application lawn-care products are different than cleaning chemicals because the dilution ratio (chemical strength) is not the critical factor. The goal is typically to throw down a certain volume of product per area. For example, the chemical label may specify 16 oz. of liquid fertilizer per 1,000 sqft.


The Spray-Alls in this section have a flow rate of 2.3 GPM @ 40 PSI water pressure. This moderate flow rate is ideal for quick coverage over large areas, and allows most small, suspended particles to pass through the body without interference.

40-degree nozzle vs. standard
Focused nozzle

The standard sprayer nozzle projects a 25-degree fan pattern, which offers a balance between wide coverage and distance. Optional alternate nozzles can provide longer-range or broader-area application. A focused nozzle will project chemical further, which is useful for shooting insecticide into tall trees and house/roof washing.

For more precise application and slower chemical usage rate, consider the low-volume Model 20 Compact Sprayer, which is shown above in this guide.

Veterinary Sanitation

Many Blue Mule products have earned a role applying disinfectants and cleaning products in animal care facilities. Mixing Stations are perfect for filling handheld spray bottles, Pump Up Foamers, mop buckets, and more – while Compact Foamers quickly disinfect kennel runs. Lafferty offers all of this and so much more!
