Self-priming sewage pump common troubleshooting

ZW-type self-priming sewage pump is self-priming and non-clogged sewage in one, the axial flow of mixed, and through the pump. Impeller flow channel of the unique design, you can send water can also be sent to send particles and fibers Sewage and manure. Widely used in municipal sewage projects, pond culture excrement disposal, sediment waste mineral impurities, light industry, paper, food, chemicals, pharmaceuticals, electricity, paddles and mixtures of chemical products such as quality products. Sewage pump with strong suction without blocking the structural design.
ZW self-priming sewage pump common fault and troubleshooting:

Symptoms	Cause Analysis	Method of exclusion
No water	1. There is no fluid in the pump housing or insufficient fluid 2. Inhalation pipe leakage 3 speed is too low 4. Suction too high or too long suction pipe 5.
