This is an underwater motor pump that achieves high corrosion and wear resistance for fresh and seawater.
The "OPD5A, 6T, 6A" utilizes hydrogenated nitrile rubber (H-NBR) for the intermediate bush/liner ring, achieving high corrosion and wear resistance. The "OPD5A" can be installed in 5" well casings and is ideal for rehabilitating 5" dual casing wells from 6" wells. The "OPD6T, 6A" has significantly reduced maximum outer diameter compared to older models, making it easy to install even in wells narrowed by scale and other factors. 【Features】 ○ Uses hydrogenated nitrile rubber (H-NBR) for the intermediate bush/liner ring → Achieves high corrosion and wear resistance ○ Employs silicon carbide (SiC) for the upper bearing and intermediate bearing/sleeve → Improves sand and wear resistance ○ Features tungsten carbide (Tgc) coating on the shaft sleeve → Dramatically enhances sand and wear resistance (optional) ○ OPD5A: Achieves installation with a maximum outer diameter of 114mm for 5" casing ○ OPD6T, 6A: Slim design with a maximum outer diameter of 142mm For more details, please contact us or download the catalog.
