WQ (QW. WQK) series submersible sewage pumpapplicable to transport containing solids and fiber of sewageor clean water.

I Service conditions

1. WQ (QW) series products in the rated voltage is380 V, power frequency for 50 Hz when used

2. 2, the temperature of the medium no more than40 °C, medium density≤1150 kg/m3, PH value in 5~ 9 rangee

3、 the altitude does not exceed 1000 meters

4、transport medium viscosity not super 1000 CP

5, products work operation must be completelysubmerged, but shall not be more than 10 m diving depth

6. the product material basically is cast iron, cannot be used in strong corrosive or containing the

orrosive mediunNote : Sure to keep the pump before the selection orinstallation using the actual conditions of use inaccordance with the above provisions, and ensure thecorrect use of products

1.Diving sewage pump impeller with double bladedesign, WQK series impeller with cutting tool device entrance,can cut some fiber not solid substance

2.Diving sewage pump motor insulation class F,protection grade IP68, S1 operate continuously;

3. Diving sewage pump oil chamber has filling oil holeGeneral pump leave factory the oil indoor already full of oil;

4. Diving the sewage pump leaking protection,overheating protection and other special requirementsusers should put forward in order;.Leak probe used for testing pump side of mechanicalseal leakage, oil chamber into water to certain proportion,probe through the electric control cabinet issued a warningsignal (indicator light) . Running thousands of hours of alarma normally, After the alarm should be replaced oil indoorlubricating oil;

6. Motor winding temperature reached rating, overheatprotector through the electric control cabinet automatic alarmand stop the motor running. When winding temperature drop,motor returned to boot state.

Note: when the submersible pump automatically stop,should find out the cause of the actual stop the pump andremove the faults again after the boot operation, ensure thepump use safety!

Technical specification

1.Diving sewage pump to the spin, from motor enddownwards see for clockwise rotation;2.The power cord and signal lines (option) logo:1 Power line: shallow blue (U), black (V), Pope (W)green/yellow()2 Protection device: shallow blue (11)-leak probeBlack (12)-leak probe Brown (21)-overheat protectorGreen/yellow (22)-The overheating protection is usuallythe signal line for the 4 x 1.0, leakage protection andthermal protection are normally open, there are otherrequirements should be provided when ordering.

Note: the above wiring must be correct and reliable,ensure the pump use safety!
