FAQs
- 1. What liquids can the YW submerged sewage pump handle?
It handles sewage, sludge, slurry, wastewater, fluids with fibers, and solid-liquid mixtures. - 2. Does the pump support fully automatic control?
Yes, it can use an automatic control cabinet to start and stop based on water level. - 3. What is the maximum allowable liquid temperature?
The medium temperature should not exceed 40°C, as stated on page 3 of the PDF. - 4. How deep can the pump be submerged?
The installation depth generally ranges from 0.5 to 7 meters. - 5. Can the pump run dry?
No. Running dry may damage the mechanical seals and cause motor overload. - 6. What is the typical pH range of applicable liquids?
The pH range is 5–9, suitable for most industrial and municipal wastewater. - 7. Is OEM customization available?
Yes, including materials, power configurations, installation plates, and flange sizes.
