Ebara Centrifugal Pumps

The Ebara DWO series consists of close-coupled, end-suction centrifugal pumps featuring an open radial flow impeller made from AISI 304 stainless steel. This design excels at handling moderately dirty liquids or those with suspended spherical solids up to 3/4" (19 mm) in diameter without clogging.

Engineers manufacture the pump body using a hydroforming process from pressed AISI 304 stainless steel, delivering exceptional corrosion resistance, structural strength, high hydraulic efficiency, and reliable long-term performance in demanding environments.

The series suits industrial applications involving solids-laden fluids, including:

• Food and beverage processing (e.g., washing vegetables, meat, fish, bottles, jars, or crates)
• Industrial washing systems and spray booths
• Water treatment
• Paint plants
• General transfer of dirty or semi-dirty water

Key Features and Benefits

• Open impeller design — Allows passage of solids while minimizing blockage risks
• Close-coupled configuration — Saves space, simplifies installation, and facilitates maintenance
• Back pullout construction — Enables easy impeller and seal servicing without disturbing piping
• Top centerline discharge — Promotes self-venting and reduces pipe load misalignment
• High-quality mechanical seals — Options for standard, high-temperature, or chemical-duty applications
• TEFC (Totally Enclosed Fan-Cooled) motors — Ensures rugged, continuous-duty operation with low noise levels (<70 dB at 1 meter)
• Connections — Typically NPT threaded (female) with hose barb options

General Specifications (across the series)

• Liquid temperature range: Up to 90°C standard (higher with optional seals)
• Maximum working pressure: Up to 116 PSI (8 bar)
• Solids handling: Up to 19 mm spherical
• Materials: AISI 304 stainless steel for wetted components
• Power options: Single-phase or three-phase, various HP ratings (e.g., 1.5 HP to higher models like DWO 400)
• Performance range: Varies by model; high flow rates with moderate to high heads for efficient operation

The Ebara DWO series offers a cost-effective, durable solution for corrosion-prone or solids-handling applications, combining Japanese engineering precision with robust Italian/European manufacturing standards for dependable performance in industrial settings.

The Ebara CDX series comprises close-coupled, end-suction single-impeller centrifugal pumps constructed primarily from AISI 304 stainless steel (with AISI 316 options available in some variants like CDXL). The innovative hydroforming process shapes the pump body and components, delivering perfectly smooth surfaces, no weld points, superior structural integrity, and exceptional corrosion resistance.

This series excels at handling clean water and mildly aggressive liquids, making it a versatile choice for applications requiring high efficiency, compact design, and reliable performance.

Common applications include:

• Domestic and commercial pressure boosting
• Water supply and treatment
• Irrigation and gardening
• HVAC and air conditioning systems
• Industrial washing, circulation, and cooling
• Heat exchangers
• Brewery processes (e.g., hot wort transfer with specialized seals)

Key Features and Benefits

• Single radial impeller design — Provides high hydraulic efficiency (often exceeding 80%) and smooth, quiet operation
• Close-coupled configuration — Compact footprint, easy installation, and simplified maintenance
• Back pullout construction — Allows servicing without disturbing piping
• Versatile mechanical seals — Standard and optional high-temperature (up to 110–120°C), chemical-resistant, or brewery-specific versions
• TEFC (Totally Enclosed Fan-Cooled) motors — Ensures continuous duty with IP55 protection
• Hydroformed stainless steel hydraulics — Enhances durability, reduces losses, and improves corrosion resistance

General Specifications (across the series)

• Liquid handled: Clean water or compatible non-aggressive fluids
• Liquid temperature range: -5°C to +90°C standard (up to +110°C or +120°C with special seals)
• Maximum working pressure: 8–10 bar (depending on model)
• Power options: Single-phase (CDXM) or three-phase, from 0.37 kW to approximately 2.2 kW (0.5 to 3 HP)
• Performance range: Flows up to around 300 LPM; heads up to 70–80 meters (varies by model, e.g., CDX 70, 90, 120, 200)
• Connections: Typically 1" to 1.5" threaded (NPT or BSP)

The Ebara CDX series combines Japanese engineering precision with robust manufacturing to offer a highly efficient, low-maintenance solution for clean water transfer in residential, commercial, and light industrial settings.

The Ebara CDU series features close-coupled, end-suction single-impeller centrifugal pumps constructed from bulge-formed (hydroformed) AISI 304 stainless steel for the liquid-end components. This advanced manufacturing process ensures superior strength, dimensional consistency, lighter weight, smooth surfaces without welds, and outstanding corrosion resistance compared to traditional cast iron designs.

Designed for rugged continuous-duty operation, the CDU series handles clean to moderately aggressive liquids, making it ideal for commercial and industrial applications requiring reliability and efficiency.

Common applications include:

• Water supply and pressure boosting systems
• Ultra-pure water systems and water treatment/reclamation
• Heat exchangers and cooling circuits
• Industrial washing, liquid transfer, and circulation
• OEM processes (e.g., chillers, beverage processing, pharmaceuticals)
• Spray systems, filtration, and car wash installations

Key Features and Benefits

• Close-coupled design — Compact footprint, simplified installation, and reduced maintenance needs
• Back pullout construction — Allows easy servicing of impeller and seals without disturbing piping
• Versatile mounting — Horizontal or vertical installation options
• Top centerline discharge with foot support — Self-venting operation and minimized misalignment from pipe loads
• High-efficiency hydraulics — Lowers operating costs with dependable performance
• Premium mechanical shaft seals and O-rings — Standard or optional for high-temperature (up to 250°F/121°C) and chemical-duty service
• TEFC or ODP motors — Rugged for continuous operation; NSF/ANSI 61 certified models available

General Specifications (across the series)

• Liquid handled: Clean water or moderately aggressive fluids (non-abrasive)
• Liquid temperature range: Up to 212°F (100°C) standard; 250°F (121°C) with optional seals
• Maximum working pressure: 125 PSI (approx. 9 bar)
• Power options: Single-phase or three-phase, from 0.5 HP to higher ratings
