Condition Of Usage
1.The depth for the electrical pump below the water is no more than 5m
2.The temperature of the water is no higher than 40℃
3.The PH figure of the water is between 6.5～8.5
4.The grain diameter of the solids in the water is no bigger than 2mm
Function And Feature
The clean water submersible pump is vastly used for aquariums mine enter-prises,gardens,family spray and irrigation,watering flower and flush. The portable power irrigation and drainage equipment is compact and light. The float switch can automatically control on and off with the change of the liquid level.The protector in the motor can automatically cut off the power when it overheated or ov-ercurrent thus guarantee the security and reliability of pump's oper-ation even in the atrocious environment
