Continuous Flow Washing Systems

Model PWRB18-48E parts washer

Multi-Stage In-Line Conveyor Parts Washers

Flat Belt pressure Spray Washer

Put Super Spray to work washing your parts. Part parameters and flexibility in the design is key for flat belt cleaning. Parts travel through the tunnel on a flat or woven wire belt with contaminants being removed by powerful water spray in combination with a specified cleaning agent, temperature and/or adjustable/different spray nozzles.

Part process through system is based on production numbers needed and surface feet per minute on the belt speed. Sample part processing can evaluate and validate sizing, pump pressures and processing stages needed to meet the finished part specification.

Standard system configuration used heated wash zone, rinse zone, and blow-off or hot air

dry finish depending on the part parameters. Filtration and oil separation are always very important for part and solution quality.

3 Stage- Wash, Rinse/Inhibit and Blow-off Dryer Conveyor Washing System

Variable speed stainless steel belt, all stainless steel construction, 2 filtration units, moisture blow-off section with 10Hp regenerative blower, 6 each 15kw heaters (4 for wash, 2 for rinse),automatic solution make-up system, removable stainless steel chip basket, exhaust duct connections and emergency stop button on both ends.


  1. Minimum shop floor space required for increased productivity per square foot.
  2. Reduced materials handling with production number increase means labor savings.
  3. Quick access to features and tanks for minimal maintenance procedures means less downtime.
  4. Multitude of applications for general surface part cleaning to stringent cleanliness specifications for aerospace, automotive, stamping operations and bearing blanks/races.


continuous flow cleaning

Concept With flow through or continuous flow cleaning systems:

The basic idea behind conveyorized cleaning systems is based on the concept of high though-put continuous flow with minimal handling of parts during the cleaning, precoating, surface preperation and preassembly. Systems can be with two different drive systems. Fixed speed for single/dedicated product. Variable speed for the wider range of different products to be processed through systems.

Pumping sizing can be of extreme importance in any washing system. Several factors must be considered for pump sizing with volumes and pressures.

  1. Area to be covered (part parameters)
  2. Materials to be removed from product
  3. Speed/Production rate

Multi-stage systems can oncprporate closed-loop solution systems for recirculation of cleaning medium and rinse-to-drain for rinsing with Rust Preventitive or DI Water prior to a drynig/blow-off stage.

  • 360 spray nozzle/manifold setup

Many nozzle styles available for different direction and cross flow spray patterns.

How dry is dry?

Absolutely dry usually calls for a true heated dryer running at 235, as a part pass through.

Blow-off dry is another preffered method throughout our industry. Function is to remove water droplets to greatly assist flash drying using stored part temperature to evaporate moisture on the surface.

What is the difference between a regenerative blower system?


Combination of a blower and a low pressure compressor. Due to their nature (regens) do warm the air delivered anywhere from 30 to 50 degrees above the surrounding air. typical uses to “squeegee” water off of relatively flat, smooth surfaces.


High volume/high velocity blowers where blind holes, recessed or large area with varying surface profile need water droplets or moisture removed. providing means for the air to exit the unit is primary concern for these blow-off systems.

There are so many different configurations, custom designed for your procedure.

semi automated systemsSemi-automated systems with minimal operator need to load/unload parts. Single plant location. indexing belts start and stop at each stage, which then robot/automation can work to load/unload production.

Baskets and fixture all can be utilized with the method of cleaning.

“U” Bend belt conveyor style spray washing system

All stainless steel, multi-stage continuous flow, filters, quick set, clip nozzles available and special “U” band design. Single plant location for operator (load/unload) and conserves on valuable floor space.

Monorail and Trolley Systems

Using fixture tree assembly on a moving overhead trolley chain system. Parts loaded on tree to go through hang on stages with system.

Seperate cleaning or combined with paint, powder coat, blasting and turnkey systems for non-stop raw to finished parts.


Rotary Drum

Rotary Drum type continuous washers can do high volume production with no manual attention needed for continued product the same as the belt style units. We have a specified auger size the entire length of our drum. The major difference with this process is parts do tumble, which there are some benefits form, as long as contact is okay.

Cleaning zone are similar with wash, rinse and or blow-pff/hot air drying. The first section is a solid drum as parts are immersed in the cleaning solution as main spray manifold extends down through drum spraying the solution under pressure. Immersion stage to perforated or wire drum for spray cleaning.

As our drum rotates as the fixed auger moves the parts forward through the stages in the rotary drum cleaning system. Single stage machines to multi-stage depending on your finished parts specifications.

Standard drum sizes: 12″, 18″, 24″ and 30″ diameter.
