features 
1   dry-type submersible pump overload protector is built-in to protect motor from over-heat and over-load 
2  inner cable wires and cable base are upgraded by filling epoxy to raise humidity-resistance 
3 motor frame and casing arc both made of stainless steel, and water-cooling jacket is designed for high efficiency of heat diffusion. 
4  stainless steel shaft is calibrated by dynamic balance lest dual mechanical seal sic / sic are installed and dual oil seals are designed to raise dust-proof 
5  impeller and agitator are both made of high chrome alloy steel (hcr) which produces high wear-resistance; impeller is also calibrated by dynamic balance test 
6  pump housing and stress eliminating plate are both made by high wear-resisting cast iron,   a innovative design of pump housing and mechanical seal lid lo reduce flow stress and last the life of seals longer
