sites, the three phase motor pump has a more stable function, the
float switch can automatically control on and off with the water
level. The protector in the motor can auto cut off the power
when it overheat or overburden
thus guarantee the security and reliablility of pump's operation
even in the atrocious environments
the pump can work properly and continously under following
1, medium is not corrosive, Sand contents should be max.0.10% by
volume and granular size should be max. 0.20mm
2, Medium temperature should not be over 40a and PH should be
3, the pumps should be operated within rated head.
4, the pumps should be fully submerged into water with depth of
less than 3m and Max. The pump should be min.0.5m over the water
bottom and not be inserted into sludge.
5, Power frequency should be 50HZ/60HZ, single phase voltage *****
three phase voltage 380V, and voltage fluctuation should be 0.9-1.1
times than the rated.
