AZCUE LN65/250 VERTICAL INLINE CENTRIFUGAL PUMP WEG 3-PHASE ELECTRIC MOTOR LNES 50-160

Product Description: AZCUE LN65/250 Vertical Inline Centrifugal Pump

1. Overview
The AZCUE LN65/250 is a robust, close-coupled vertical inline centrifugal pump, designed for efficient and reliable transfer of clean or slightly dirty fluids in industrial, commercial, and municipal applications. Its inline design allows for installation directly into the pipeline, saving significant space compared to traditional end-suction pumps. The integration with a high-performance WEG 3-Phase Electric Motor (Frame LNES 50-160) ensures dependable, low-maintenance operation.

2. Key Features & Benefits

• Vertical Inline Design: Enables installation in straight piping runs without the need for a baseplate or concrete foundation, minimizing footprint and installation costs.

• Close-Coupled Construction: The impeller is mounted directly on the extended motor shaft, ensuring perfect alignment, reduced vibration, and mechanical simplicity.

• Heavy-Duty Construction: Typically constructed with cast iron casing (EN-GJL-250), bronze or stainless steel impeller, and a mechanical seal suitable for a wide range of fluids.

• Space & Cost-Efficient: Eliminates the need for coupling guards, alignment procedures, and large mounting bases.

• Reliable WEG Motor: Features a premium 3-phase, squirrel-cage induction motor from WEG, known for high efficiency, durability, and global service support. The LNES 50-160 frame indicates a specific motor power and mounting configuration.

• SEO-Optimized Note (LNES 50-160 SEO): The “SEO” suffix likely denotes a Single End Output shaft, confirming the standard configuration for close-coupled pumps.

3. Technical Specifications (Typical)

• Pump Model: AZCUE LN 65/250

  • 65: Nominal Discharge Port Size (DN 65, approx. 2.5 inches).

  • 250: Nominal Impeller Diameter (in mm).

• Motor: WEG 3-Phase, IP55 (or higher) enclosure for dust and water jet protection, Class F insulation.

• Motor Frame: LNES 50-160. This decodes as:

  • L: Frame series (Metric IEC standard).

  • NE: Specific flange mounting design (likely B14 flange as per IEC standard).

  • S: Short shaft length (common for close-coupled pumps).

  • 50: Center height in mm (e.g., 50mm ≈ Frame size 56).

  • 160: Dimension from base to shaft centerline in mm.

• Performance Range (Example – Varies with Speed):

  • Capacity (Flow): Up to ~50 m³/h (~220 US GPM)

  • Head (Pressure): Up to ~32 meters (~105 ft)

  • Power: Depending on specific motor selection, typically in the range of 3 – 7.5 kW (4 – 10 HP).

• Operating Conditions:

  • Fluids: Clean, non-aggressive, thin liquids (water, light oils, compatible chemicals).

  • Temperature: Standard seals allow for fluid temperatures up to ~90°C (~194°F).

  • Max Pressure: Typically 10-16 bar for the pump casing.

4. Typical Applications
This pump is ideal for applications requiring compact, installed-and-forget reliability:

• HVAC systems (chilled water, condenser water circuits)

• Industrial water supply and pressure boosting

• Cooling towers and heat exchangers

• Irrigation and water transfer

• General fluid transfer in manufacturing plants

5. Why Choose This Package?

1. Integrated Solution: Perfectly matched pump and motor unit from reputable manufacturers (AZCUE & WEG).

2. Low Maintenance: Close-coupled design eliminates alignment issues; mechanical seal is the primary wear part.

3. Global Standards: Built to ISO and IEC metrics, ensuring parts availability and interchangeability.

4. Space Savings: The vertical inline configuration is the optimal choice for space-constrained plant rooms or inline installations.
