BJM Mechanical Seals

BJM Mechanical Seal — Double Seal by Shaft Size

BJM mechanical seals are double mechanical seals in a single-spring design, built for BJM submersible pumps — choose your shaft size from the dropdown and you’ll get the right seal for your pump. Each is a complete upper-and-lower seal set, built to OEM-equivalent standards or higher for the same fit and reliability as the original.

Standard build: Carbon/Silicon Carbide upper face and Silicon Carbide/Silicon Carbide lower face, with Viton (FKM) elastomers. Seat style varies by shaft size — see your selected option.

How to Order

Select your shaft size above — the price and seal details for that size will update. Not sure which size you need, or matching from a worn seal? Measure your shaft, or send a photo of the old seal and your pump nameplate to info@sealhouseusa.com, or call/text 561-414-1046. No purchase required — our seal specialists will match it.

The 45mm BJM seal (M01355V / 200433) is the same seal as our Ebara 260D mechanical seal and our HCP F21-0B045NS0000-0 mechanical seal, listed separately under each brand. It also cross-references to US Seal VGM-1335V and fits the BJM K2N220.
