Submersible water pump parameter:

submersible water pump overview:
QJ series submersible water  pumps advantages are an optimized design, solid structure, low running noise, a long running life, small size, light weight, easy to install and maintain, energy saving characteristics, steady in operation, and minimal pollution. Application; for deep well water, farm irrigation, sprinkler irrigation, urban and rural industries as well as mine supply and drainage.

Submersible water pump feature:
1. Motors and pumps assembled into one.
2. Simple structure.
3. Easy installation and removal, compact.
4. Simple use and maintenance.
5. Safe and reliable operation, no pollution to water.

Submersible water pump working condition:
