- Continuous submerged operation improves sealing stability
Compliance & Quality Assurance
- Hydraulic performance test before delivery
- Cutting mechanism operational verification
- Motor insulation resistance and winding test
- Mechanical seal leakage integrity test
Safety Notice
- Do not operate under dry-running condition
- Ensure full submergence before startup
- Disconnect power before maintenance
- Do not exceed rated voltage and frequency

Q: Can the pump operate under VFD control?
A: Yes, VFD can regulate rotational speed and adjust hydraulic and cutting performance.
Q: What is the maximum allowable solid size?
A: It depends on the cutter mechanism design and discharge diameter specification.
Q: What sealing configuration is used?
A: Dual mechanical seal with oil chamber protection is standard.
Q: Is the cutting blade replaceable?
A: Yes, cutter components are serviceable and replaceable.
Q: What is the allowable working pressure?
A: The pump should operate within the rated working pressure defined per model.
Q: Can it handle sanitary wipes and textiles?
