WQ non-jamming diving pollution discharge pump(hereafter refersto as electric pump),by the water pump,the seal,the electric motor three parts is composed.electric motor located at electric pump on,for single-phase or three different step electric motor.Between the pump housing and the electric motor uses the double-end surface mechanical seal,each solid stops the mouth seal place use "O"the shape oil resietant rubber seal packing collar to make the static seal surely.This serious electric pump has the structure to be compact,the current capacity is big,the efficiency is high,the easy to operate and so on superior the spot,the essential spot's mechanical seal uses the hard alloy and the high quality carbonization sillicon is the material,has the good corrosion preventing,against leakage,durable and so on characteritics.This serious electric pump does not have the jamming slush pump,can discharge in the liquid the foreign inclusion to compare does not surpass 2.5%,the particle diameter is not bigger than 18mm the impurity,and does not stop up,does not twine.
