Used Alfa Laval WSPX-307-71G Desludging Disc Stack Centrifuge – 8,375 RPM, 7.5 kW

Description

Used Alfa Laval Model WSPX-307-71G desludging disc stack centrifuge with a 316 stainless steel bowl assembly, aluminum bowl covers and maximum bowl speed of 8,375 RPM. Features a concentrator configuration for liquid/liquid/solids separation, with light-phase liquid discharge through a centripetal pump. The rotating disc stack separates components according to density, allowing two liquid phases to separate while denser solids collect at the bowl periphery for discharge. Listed capacity is approximately 22 GPM, depending on feed composition, viscosity, operating temperature and separation requirements. Sludge space is approximately 0.87 gallons. Equipped with a belt drive powered by a 7.5 kW motor rated for 380 volts, 3-phase, 50 Hz. Mounted on a supporting frame. Possible applications include removal of separable tramp oil and suspended solids from compatible water-based metalworking coolants, parts-washing liquids and industrial process water, subject to fluid compatibility and installed separation configuration.

Product Details

Potential Applications

• Removal of separable tramp oil and suspended solids from compatible aqueous industrial fluids.
• Metalworking coolant cleanup and fluid recovery.
• Parts-washing liquid clarification and oil separation.
• Treatment of compatible industrial process water containing separable oil and solids.

What Products Would This Be Used For?

Potential feed materials include:

• Water-based metalworking coolants contaminated with separable tramp oil and suspended particles.
• Aqueous parts-washing liquids containing oil and solid residues.
• Machine-tool coolant return streams.
• Industrial process water containing separable oil droplets and suspended solids.

Suitability depends on fluid chemistry, emulsion stability, viscosity, density differences, solids loading and operating temperature. For formulated coolants, confirm that separation preserves the intended coolant composition.

Frequently Asked Questions

• What separation configuration does this centrifuge have?
  The listed concentrator configuration provides liquid/liquid/solids separation.

• What is the maximum bowl speed?
  The maximum listed bowl speed is 8,375 RPM.

• What materials are used in the bowl assembly?
  The bowl assembly is listed as 316 stainless steel with aluminum bowl covers.

• What is the processing capacity?
  The listed capacity is approximately 22 GPM. Actual throughput depends on the feed and required separation performance.

• How much sludge space does the bowl provide?
  Listed sludge space is approximately 0.87 gallons. This describes bowl solids space, rather than a solids-throughput rating.

• How does the light liquid phase discharge?
  The light phase discharges through a centripetal pump.

• What motor and drive arrangement are installed?
  The centrifuge uses a belt drive powered by a 7.5 kW motor.

• What electrical service does the motor require?
  The listed motor rating is 380 volts, 3-phase, 50 Hz. Confirm the complete system’s electrical and utility requirements before installation.

• Can it remove tramp oil from metalworking coolant?
  This is a potential application when the contaminating oil is separable from the coolant. Review the formulation, emulsion stability and desired fluid composition before selecting operating conditions.

• Are control panels and auxiliary equipment included?
  The supplied description establishes frame mounting but does not identify included controls, feed pumps or auxiliary equipment. Request confirmation of the equipment scope.

• What information is needed for shipping?
  Request confirmed shipping dimensions, weight, pickup location and loading requirements for stock 46665001.

• How can Aaron help evaluate this centrifuge?
  Contact Aaron with the fluid type, contamination level, operating temperature, required throughput and separation target to discuss the equipment and available documentation.
