Frequently Asked Questions

Q1: What is the primary advantage of a split case pump?

The axially split casing allows for easy access to internal components like the impeller and shaft without disturbing the motor or pipework, significantly reducing maintenance time.

Q2: Can these pumps handle high-temperature liquids?

Yes, these pumps are designed to operate efficiently within a temperature range of 0°C to 105°C, making them suitable for district heating and industrial processes.

Q3: What materials are available for corrosive environments?

For corrosive or seawater applications, we offer impellers and casings in bronze, silicon brass, and various grades of stainless steel.

Q4: Are the pumps suitable for fire protection systems?

Absolutely. Their high reliability, large capacity, and stable performance make them an ideal choice for large-scale firefighting and district water supply systems.

Q5: Do you support customized OEM/ODM requirements?

Yes, we accept OEM and ODM orders. We can manufacture pumps according to your specific technical specifications and material requirements.

Q6: How is the quality of the pump balance ensured?

Every impeller undergoes both static and dynamic balancing tests. Additionally, the double suction design naturally balances axial forces to ensure smooth, vibration-free operation.
