Key Features

• Direct OEM Replacement: Precisely engineered to match the dimensions, spring force, and material specifications of original Kewpump seals, ensuring a perfect fit and drop-in installation without pump modification.

• Versatile Elastomer Options: mechanical pump shaft seals are available in a range of elastomers to ensure optimal chemical compatibility with the specific pumped media, from hot water and steam (EPDM) to oils and fuels .

• Self-Aligning Bellows Design: The elastomer bellows provides excellent flexibility, automatically compensating for minor shaft misalignment, runout, and axial movement, which reduces stress on the seal faces and prevents premature failure.

• Shaft Protection: Unlike pusher-type seals, the elastomer bellows eliminates the need for a dynamic O-ring, preventing fretting corrosion and scoring of the pump shaft, thereby protecting the critical shaft surface.

• Robust Face Materials: Standard ceramic/carbon combinations offer cost-effective sealing for general applications, while optional Tungsten Carbide (TC) faces are available for high-abrasion or high-temperature services, significantly extending seal life.
