Working Principle of Vertical Split Case Pump
Vertical Split Case Pumps combine space efficiency with hydraulic balance through a vertically split casing and double-suction impeller. Core functionality:
Axial Force Neutralization
Dual-entry impeller cancels 98% thrust loads, eliminating bearing stress (±2% residual).
Compact Footprint
Vertical orientation saves 60% floor space vs. horizontal equivalents.
Top/Bottom Access
Bolted casing halves enable full rotor service without pipe disconnection.
High-Head Capability
Staged diffusers achieve ≤300 m head at 15,000 m³/h (ISO 5199).
Key Advantages of Vertical Split Case Pump
Space Dominance
0.6 m² base area – ideal for cramped pump rooms.
01
Maintenance Speed
Replace wear parts in <3 hours (70% faster than inline pumps).
02
Energy Efficiency
90% peak efficiency – 8% higher than end-suction designs.
03
Zero Cavitation
Low NPSHr (1.2 m) prevents vapor lock at 120% flow.
04
Smart Diagnostics
IoT vibration/temp sensors predict failures via 4–20mA/Modbus.
