First, the product overview DFWQ submersible sewage pump main components from the impeller, pump body, base, submersible motor. Pump and motor are the same shaft, the pump body is located at the bottom of the entire sewage pump. It can maximize the suction area of ​​the remaining sewage. DFWQ submersible sewage pump embodies the sewage channel, non-clogging, anti-wrap characteristics. Product implementation JB / T5118-2001 "sewage sludge submersible pump." This series of pumps have been "utility model patent certificate" patent number: ZL.0. DFWQ submersible sewage pump Second, the product features 1, the cable is durable, waterproof: oil heavy rubber cables, resin infusion, compression fixed, no pull, long-term reliability. 2, beautiful appearance, safe and reliable: 7.5kW / 2 the following motor design for the boutique form, the casing is stainless steel tube, beautiful and durable; 11kW motor using a specially designed inner cooling, to ensure the safe operation of the motor in the dehydrated condition; jacket For the steel roll into; back-mounted angular contact ball bearings and deep groove ball bearings match, carrying capacity, to ensure smooth operation of the pump. 3, double seal, double protection: double machine seal series configuration, the real double protection to ensure motor safety. 4, multi-channel detection, multi-channel protection: oil-water probe, float switch, can be real-time detection and alarm, shutdown, fault signal retention and other functions to make submersible motor safe and reliable. 5, over-flow ability: DFWQ submersible sewage pump is currently more popular dual-flow impeller, significantly increased the dirt flow capacity. DFWQ submersible sewage pump specially designed for the optional automatic mixing device, the sewage discharge performance compared with the traditional sewage pump better, especially for higher concentrations of sewage occasions. 6, easy maintenance: advanced coupling device, so that when the pump take off and landing without underwater operation, easy maintenance, saving time and labor. Third, the working conditions Flow range: 7 ~ 3840 m3 / h Head range: 2.8 ~ 43m Diving depth: ≤ 20m Medium temperature: -15 ℃ ~ +60 ℃
