Lepu Seal provides Blackmer pump seal for its being used in the clean, non-corrosive industrial liquids and petroleum products. The typical applications include fuel oils, lube oils, jet fuels, gasoline, and edible oils industries.

We carefully select high-quality SSIC as the raw material for stationing and rotating the seal face. According to scientific theory, the silicon carbide can stay stable under the high temperature of over 1400°C and have excellent dimensional stability above 400 GPa. Under the chemical environment, silicon carbide helps the product resist the corrosion and erosion and improves its ability to withstand friction and wear. The product has a cartridge seal designed frame which allows it to be installed and maintained easily. We use carbon and SIC as the raw materials for manufacturing the rotary and stationary seal parts. Due to the characteristics of the SIC, the product is endowed with the performance of stable chemical properties, low thermal expansion coefficient and good wear resistance. Besides that, the product is equipped with strong cast iron which gives it long service life. As for the secondary seal, we use EPDM to help the product gain the advantages of weather resistance, ozone resistance, heat resistance, acid and alkali resistance.

At Lepu Seal, we ensure that the product is designed totally based on the original Blackmer mechanical seal.
