Water Pump seals are designed for use in small centrifugal water pumps, deep and shallow well jet pumps, swimming pool pumps, submersible pumps, and wastewater pumps.

Product Description

Mechanical Shaft Seals for Pumps WM FBW are manufactured by full automated assembling lines at our global production sites and have high market share worldwide specifically in the category of seals for automotive water pumps. These seals are also suitable for industrial pumps. Because mechanical seal failures are the number one cause of pump downtime, uses only top of the line materials when it comes to manufacturing this critical seals. most pump shafts were sealed using rings of soft packing, compressed by a packing gland, but this type of shaft seal required a fair amount of leakage just to lubricate the packing and keep it cool. Supported by our experience of the industry, Wendong, famous pump seal manufacturers in China, has been able to manufacture, supply, trade, and export a qualitative range of Water Pump Mechanical Seal used in various industries.
