FAQs

  1. 1. What liquids can the YW submerged sewage pump handle?
    It handles sewage, sludge, slurry, wastewater, fluids with fibers, and solid-liquid mixtures.
  2. 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. 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. 4. How deep can the pump be submerged?
    The installation depth generally ranges from 0.5 to 7 meters.
