The invention belongs to the technical field of water pump application, and particularly discloses an efficient water suction pump applied to
sewage or
clean water. The pump comprises an M-shaped upper pump shell, a main body and a base which are matched with each other, a
float switch, a power supply plug, first screws, a first cable guard sleeve, a second cable guard sleeve and a set of cable clamps which are arranged on the M-shaped upper pump shell and matched with each other, and a
capacitor, a
capacitor buckle, second screws, a back cover, a wave-shaped
washer, a first bearing, a first clamping spring, a rotor, a second clamping spring, a second bearing, a
stator, a
front cover, a set of framework oil seals, a second O-shaped seal ring, a
steel ball, a spacer, impellers, a lock nut, a third O-shaped seal ring, third screws, the back cover, fourth screws, an
elbow pipe, a first O-shaped seal ring and a straight
pipe which are matched with each other. The efficient water suction pump applied to
sewage or
clean water has the advantages that the pump is reasonable in design and structure, large in lift and power, low in
noise, smooth in
pollution discharge without blocking phenomenon at the same time, and is suitable for being used in production operation of the
clean water or the
sewage in an assembled mode.
