This is a submersible motor pump that meets the drinking water extraction performance standards and complies with RoHS environmental standards.
"OPDS8H,8J" employs hydrogenated nitrile rubber (H-NBR) for the bearings/liner rings, achieving high corrosion and wear resistance. The upper bearing uses silicon carbide (SiC), enhancing sand and wear resistance. The impeller and casing are designed for high efficiency and lightweight using 3D analysis software. A rich selection of shaft materials enables large-capacity pumps. A compact body has been realized. 【Features】 ○ Uses hydrogenated nitrile rubber (H-NBR) for bearings/liner rings → Achieves high corrosion and wear resistance ○ Uses silicon carbide (SiC) for the upper bearing → Improves sand and wear resistance ○ Employs ceramic coating on the shaft sleeve → Dramatically enhances sand and wear resistance (optional) For more details, please contact us or download the catalog.
