Our advantages

1. 135 degree thermal protector: high efficiency; be stopped automatically; avoid to burning when overloaded or other abnormal operation
2. 600# Cold Rolled Silicon Steel Sheet: better quality than normal material; longer using life; higher efficiency; enough power
3. High efficiency bearing: silencing; smoothly moving; abrasive resistance; ultra-high hardness; long service life
4. Stainless steel rotor: SS 304 welding; high quality; high performance; stable operation
5. High quality float impeller: Enhanced ABS; High strength PC composite polymer material; more resistant and durable
6. Sand prevention ring: the impeller use ABS material, which is stronger than pom material. Our impeller have the patent for the sand prevention structure, which can prolong the life of the impeller, improve the pump efficiency
7. Food machinery oil: use the food machinery oil which can protect the water out of pollution when the oil leaking happens.
8. Mechnical seal: use carbon graphite and silicon carbide mechnical seal, wear-resisting, longer life
9. Cable: selected the special cable which can use in the temperature from -40 degree to 80 degree
10. Thicker thickness of pump casing and motor casing
11. Screw: all the pump screw use 304 stainless steel, compared with the normal screw, no rust, no broken
