[Three rain valve to recommend Star Products - Mechanical seal] Introduction: This pump seal oil chamber with high precision interference leakage detection sensors, and embedded in the stator windings of the thermal components, the absolute protection of pump motor. According to user needs with automatic security control cabinet WQ10-35-3 pumps, pump leak, leakage, overload and overtemperature absolute protection, improved product safety and reliability. Float switch may vary depending upon the desired fluid, automatic control pump start and stop, without special care, extremely easy to use. [Three rain valve to recommend star products - mechanical seals] Description: sewage pumps belong to a centrifugal impurity, a variety of forms: as diving and dry two kinds WQ18-30-3 pumps, the most commonly used the WQ-diving submersible sewage pump WQ25-15-2.2 pumps, the most common dry-sump pumps such as W-type horizontal WL vertical sewage pumps and sewage pump two kinds. Urban sewage pump is mainly used for transport, manure or liquid containing fibers. Paper and other solid particles in the medium, the transmission medium temperature is usually not more than 80 ℃. Since the medium is transported contains easy to wound or bunching the fiber material. So the kind of easy to plug the pump flow, pump once clogged pump is not working properly, or even burning motor, resulting in poor sewage. Serious impact on urban life and environmental protection. Thus, anti-blocking and reliability is an important factor in the merits of the sewage pump. WQ25-15-2.2 pumps | sewage pump selected three rain (certified) | Wuzhou water pump provided by Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd. of Tianjin, rain (www.tjsymf.com) (www.tjsymf.com) is a leader in Tianjin, seals, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Three rain valve leadership with the staff warmly welcome all inquiries negotiations to create three rain valve better future.
