Horizontal Multistage Centrifugal Pump for Boiler Feed Water DG
Introduction
The DG Horizontal Multistage Centrifugal Pump is specially designed for boiler feed water systems and high-temperature liquid transfer. It is a single-suction, multistage, segmented centrifugal pump that delivers high pressure through multiple impellers arranged in series.
This pump is ideal for handling clean water or liquids with similar properties, especially in applications requiring stable high-pressure output and high-temperature resistance.
Product Structure
The DG series pump features a robust and service-friendly design:
• Horizontal Multistage Structure: Multiple impellers increase pressure step by step
• Segmented Pump Casing: Easy to disassemble and maintain
• Vertical Inlet & Outlet Design: Optimized for boiler system installation
• High-Strength Shaft: Fully protected to prevent corrosion and extend lifespan
• Guide Vanes (Diffusers): Efficiently convert velocity into pressure
• Sealing System: Packing seal (standard) or mechanical seal (optional)

Working Conditions
The DG pump operates using a multistage centrifugal mechanism:
• Liquid enters the first-stage impeller
• The impeller increases fluid velocity
• The diffuser converts velocity into pressure
• The liquid flows through multiple stages, gradually increasing pressure
This process ensures stable and high-pressure discharge, making it ideal for boiler systems.
