The newly launched submersible sewage pump is developed by screening and improving similar WQ series products at home and abroad to overcome their shortcomings. Rational optimization and innovative design are carried out in hydraulic model, sealing technology, mechanical structure, protection and control, etc., making it more reliable, safe, lightweight, and practical, with long life and good sewage performance; The whole series of products, the type spectrum is reasonable, easy to select. It is equipped with a special electric control cabinet for the submersible pump to realize its protection and automatic control.
Model screening: Performance optimization, two-channel impeller, reasonable arrangement of two to three mechanical seals, so that the mechanical seal lubrication and cooling are ideal, smooth operation without plugging, and good flow capacity.
Seal improvement: With series mechanical seals, shaft seals are more reliable and have longer service life.
Structural optimization: The structural design is conducive to the sealing of the machine seal, smooth operation, vibration resistance, drop resistance, and higher reliability; Optimized design, the sewage pump more portable and practical, with more corrosion resistance, and wear resistance.
IPX8 motor protection grade, the submersible motor cooling effect is good, the temperature rise is lower than the ordinary motor, the durability is further improved, and F class insulation promotes the motor's longer service life.
The motor is equipped with a variety of protection devices, which can facilitate the user to optimize the selection.
