3. CNC lathe precision machining ensures parallelism and perpendicularity of all the parts and also the pumps concentricity, extending its service life.

4. Rigorous testing, well installation and full load performance test.

5. The service life of the improved rubber bearing liner (technological secret) is 2 times longer than that of common bearing liner.

6. The material of the pump shaft:general chromium-plating, 2Cr13, stainless steel 431, stainless steel 631, monel, etc.

7. Material of impeller: stainless steel 304,316,316L, tin bronze and aluminum bronze, etc.

8. Some of our productsproduced by introducing the Germany Ritz technology, increasing the pumps outer diameter, meanwhile meeting the customers needs of high head submersible pump.
