LG Vertical multistage feeding water pump

A vertical, single‑suction multistage centrifugal pump designed for high-rise building water supply and other industrial water duties. Engineered to JB/T2727‑93 standard, the pump features a disassemblable, compact construction that saves floor space and simplifies installation and maintenance.

Key features

• Vertical multistage, single‑suction design for high head with a small footprint
• Disassemblable sections (inlet, middle, outlet) joined by tensioning bolts for easy access to internals
• Rotor assembly includes shaft, impellers, spacer sleeves and shaft sleeve for stable, balanced operation
• Shaft sealing options: soft packed seal or mechanical seal; seal chamber is lubricated and cooled by pressure water into the balance chamber
• Low noise, energy‑efficient operation suitable for continuous service
• Suitable for liquids with physical properties similar to water; operating medium temperature range 0 °C to 80 °C

Typical applications

• Domestic and municipal water supply for high‑rise buildings
• High‑rise building fire water systems
• Circulation and transfer of clean water in factories, mines and enterprises
• Drainage and circulating water for low‑pressure boilers

Installation & maintenance notes

• Requires a level, rigid base and proper alignment of suction/discharge piping to avoid axial loads on the pump
• Select the appropriate shaft seal type (soft packing or mechanical seal) based on duty cycle and maintenance preferences
• Avoid pumping liquids containing abrasive solids or corrosive chemicals not compatible with pump materials
• Periodic inspection of seals, bearings and fasteners is recommended to maintain efficiency and reliability
