Return sludge pump

Common use:

QJB-W type return sludge pump is for a submersible mixer of new products, the pump as secondary sewage treatment plant mixture, denitrifying nitrogen backflow of special equipment, also can be used when the ground drainage pumping purifying water; Irrigation and control waterway system; Wastewater treatment process recycling or slurry pump loop of the need to the head, big flow places.
Conditions of use:

1, continuous operating temperature, medium is not higher than 40 °C;

2, medium PH value of 6-9.

3, the biggest potential no depth 10 m.

Structure introduction:

Mainly by the host, diversion tube, installation system, wear wall tube, pat door composition. Host structure and the structure of the mixed mixer points;

The purpose is to guide tube forming the best flow state; Wear wall tube and take the door is in order to better connect, and rich and stop running on the host, can well block between two pool the connected.

Product features:

1, according to the head of the big flow special design, high efficiency; 2, the host machine adopts stamping type hydraulic structure, good performance, high efficiency; 3 and integration of hoisting equipment, which can realize in underwater fast installation maintenance; 4, internal leakage leakage and motor overload protection (alarm) device, ensure product safety and reliability.
