QWB series submersible sludge return pumps use mainly for municipal engineering, environmental engineering, sewage treatment industry, vertical mixer horizontal mixer powder mixer weightlessness mixer can be used for the carriage of solid particles and fibers with sewage, return sludge, wastewater. Features QWB series submersible sludge return pump head by micro, PCB design high flow, high efficiency design, the product features: 1: Micro-head, high flow. The series submersible sludge return pump stamping stainless steel submersible mixer as pumping host, impeller speed lower than 1600 rpm, so the unit flow, head low (up to 0.5 m), ideal for small liquid drop , high flow requirements occasions (such as sewage sludge treatment process reflux section). Ribbon mixer vertical ribbon mixer horizontal ribbon mixer does not supplies of coarse recycled supplies logistics software ご Mi 2: non-clogging, high efficiency. Marketing consulting firm advertising campaign due to inter-reflux drum and impeller flow channel with a larger space, but not narrow the gap, and leaves swept type, inclinometer makes the media in a variety of solid particles, even very easy to wound The fiber debris, as long as the sludge return pump suction into the mouth, it can be transported out unhindered, hydraulic model using CFD fluid analysis software design, high hydraulic efficiency and the high number of poles impeller submersible motor directly connected, mechanical loss, making QWB series submersible sludge return pump unit and very efficient. 3: All stainless steel construction, corrosion resistance. The series submersible sludge return pump with stainless steel construction, automatic doors revolving door machine sleek, beautiful, small number of parts, a high degree of standardization. Conditions of Use: 1: altitude not exceeding 2000m, maximum ambient temperature of 50 degrees Celsius, PH value of the medium between 3--12, liquid density does not exceed 1150kg / m ?, long run diving, diving depth of not more than 20m; 2: Run the pump must not fall below the minimum level. 3: The rated voltage of 380V, rated frequency 50HZ. The deviation in the rated voltage and rated frequency of no more than plus or minus 5%, the motor to run properly. Rotation direction: from the pump outlet, the impeller to rotate counterclockwise. Ordering instructions: Proper installation is essential to ensure the long-term QWB series sludge return pump working. QWB series sludge return pump rail automatic coupling installation system: rail fixed to the wall, while the installation of fixed shore lifting device and wall outlet, sludge return pump can slide freely up and down along the rail, installation and maintenance is very easy .
