Split Case Pump

Advantages of Split Case Pumps

1. Easy maintenance: The Pump casing can be split along the horizontal axis and the internal components can be inspected without removing the pipes.

2. High efficiency: Volute/diffuser design ensures smooth fluid flow under high pressure.

3. Strong durability: Strong materials such as cast iron and stainless steel can withstand harsh working conditions.

4. Large-capacity transportation: It can handle high-flow fluids (maximum flow is 18000m³/h), suitable for municipal water supply and industrial circulation with low pump body vibration.

5. Flexible design: Suitable for various installation scenarios and pressure requirements.

Main Components of a Split Case Pump

1. Split case: Encapsulates the impeller and can be split along the horizontal plane for easy maintenance.

2. Impeller: The core energy transmission part, which transmits kinetic energy to the fluid by rotation. The material can be cast iron, stainless steel, and high chromium cast iron for particles.

3. Shaft and bearings: Support the rotation of the pump shaft and reduce friction and wear.

4. Sealing: Prevent leakage along the shaft and ensure the sealing of the pump body.

5. Discharge and suction nozzles: Connect the pump to the piping system.

6. Bottom plate: Supports the entire assembly, absorbs vibrations and ensures stability.

Application Scenarios

1. Municipal water supply：Urban drinking water delivery, large water plant water delivery systems.

2. Power generation：Circulating cooling water transportation in power plants.

3. Industrial processes：Chemical, metallurgical and other industries handle chemicals, slurries or large amounts of industrial liquids.

4. Fire fighting system：Rapidly deliver fire fighting water in emergency situations.

5. HVAC system：Chilled water and cooling water circulation in large buildings or factories.

Installation Tips

1. Ensure proper alignment to prevent excessive wear, that is coupling non-concentricity ≤ 0.1mm, end face gap unevenness ≤ 0.3mm. Use appropriate base concrete to minimize vibration.

2. Check seals and bearings regularly to make sure seal leakage ≤ 5 drops/minute.

3. Maintain a lubrication schedule.

4. Pay attention to vibration and noise levels.

Maintenance Tips

1. Clean the filter and screen at the inlet to prevent debris from entering the pump body and wearing out the impeller.

2. Regularly inspection: check seals and bearings once every 3-6 months and replace aging parts.

3. Maintain a lubrication schedule: regularly add lubricant to bearings to avoid dry friction.

4. Monitor flow rate and pressure: monitor in real time through instruments and promptly troubleshoot any anomalies (e.g., a drop in flow may indicate impeller blockage).

5. Comprehensive maintenance once a year: disassemble the casing to check the wear of the impeller and volute, and clean the internal dirt.

Common Troubles and Remedies

Selection Points

1. Parameter matching：Determine the flow rate and head according to the working conditions and the actual flow rate/head is within 80-110% of the pump rating. Single-stage split case pumps are suitable for medium and low heads.

2. Fluid adaptation：Select materials and impellers based on fluid corrosivity, temperature, and viscosity.

3. Space adaptation：Vertical type is suitable for narrow space, horizontal type is suitable for high flow rate.

4. Adapt the power supply：Ensure that the motor voltage and frequency of the pump are consistent with the power supply available on site.

5. Energy saving first：Energy-saving pumps with variable frequency are preferred to reduce operation and maintenance costs.

6. Material compatibility：The pump body and impeller need to be resistant to fluid wear and corrosion.

Innovative Direction in Split Case Pump Technology

1. Smart pumps:Integrate IoT for remote monitoring.

2. Energy-saving design: Focuses on reducing operating costs.

3. Advanced materials: Better wear and corrosion resistance.

4. Automation and Control: Improved sensors and control systems for optimal operation.
