Why Choose a Horizontal Split Case Pump?
Before identifying the right horizontal split case pump manufacturer in China, it is essential to understand why this pump configuration is preferred for high-flow, continuous-duty applications. (You may be interested in end suction pump VS split case pump.)
What Is a Horizontal Split Case Pump?
A horizontal split case pump features a casing that splits horizontally along the shaft centerline. Both the suction and discharge nozzles are located on the lower casing half. This design offers several advantages over end-suction or vertically split pumps.
Key Advantages of Horizontal Split Case Pumps
| Feature | Benefit |
|---|---|
| Double-suction impeller | Self-balancing axial thrust → longer bearing life |
| Horizontal casing split | Maintenance access without removing piping → reduced downtime |
| High flow capacity | Single pump handles up to 38,000 m³/h |
| Low NPSH requirement | Superior suction performance for challenging intake conditions |
| High efficiency | 85-92% at best efficiency point → lower energy costs |
| Easy inspection | Open top cover to inspect impeller, wear rings, and seals |

Horizontal Split Case Pump vs Other Pump Types
When selecting a horizontal split case pump manufacturer in China, it helps to understand why this pump type is preferred over alternatives.
| Pump Type | Flow Range | Best Application | Maintenance |
|---|---|---|---|
| Horizontal split case | 135 – 38,000 m³/h | High flow, continuous duty | Easy (no pipe removal) |
| Vertical turbine pump | 50 – 8,400 m³/h | Deep wells, limited footprint | Moderate |
| End suction pump | 10 – 5,000 m³/h | Low flow, high head | Difficult (pipe removal) |
| Vertical mixed flow pump | 500 – 20,000 m³/h | Low head, high flow | Moderate |
For most water supply, cooling circulation, and hydraulic engineering projects, the horizontal split case pump offers the best combination of efficiency, maintainability, and reliability.
Key Features of XSP Horizontal Split Case Pump
A. Double-Suction Impeller – Balanced Axial Thrust
The double-suction impeller design means flow enters from both sides of the impeller, canceling axial thrust. This results in:
- Smaller, cooler-running bearings
- Longer bearing life (typically 5-10 years)
- Reduced vibration
- Lower maintenance costs
B. Horizontal Split Casing – Easy Maintenance
The casing splits along the horizontal centerline. To inspect or service the pump:
- Remove nuts on top cover
- Lift upper casing half
- Access impeller, wear rings, and seals
- No need to disconnect suction or discharge piping
Downtime saving: 50-80% less time compared to end-suction pumps.
C. High Efficiency – Lower Energy Costs
XSP split case pumps achieve 85-92% efficiency at the best efficiency point (BEP). For a pump operating 8,000 hours per year, a 5% efficiency advantage saves tens of thousands of dollars annually in electricity costs.
D. Low NPSH Requirement – Better Suction Performance
The double-suction design reduces inlet velocity, lowering the NPSH required. This allows:
- Higher installation above water level
- Operation with limited submergence
- Reliable performance in irrigation and river intake applications
E. Wide Material Selection – Compatible with Various Fluids
| Fluid Type | Recommended XSP Material |
|---|---|
| Clean fresh water | Cast iron or Ductile iron |
| Raw water with sediment | Ductile iron with hardened wear rings |
| Cooling water (mildly corrosive) | SS304 or SS316L |
| Seawater or brackish water | SS2205 Duplex or SS2507 Super Duplex |
| Highly corrosive industrial fluids | 904L or CD4MCu |
F. Temperature Rating – Suitable for Hot Water
With a temperature rating up to 150°C, the XSP series is suitable for:
- District heating circulation
- Industrial hot water systems
- Power plant auxiliary cooling
