Yeomans 250CLC Mechanical Seal Set — Upper & Lower

Direct-fit upper and lower mechanical seals for the Yeomans 250CLC pump. Matched sizes and materials for reliable sealing and simplified rebuilds.

What’s included

• Upper seal: MG9 style, 2-1/4″ — Carbon / Silicon Carbide / Buna-N (CAR/SIC/BUNA)

• • Spring note (MG9 upper): Our upper MG9 seal uses an American-style, bi-directional spring (not the tapered spring seen on some OEM builds). We standardize this spring style because it fits more applications and simplifies service.

• Lower seal: 2100 style, 2-1/8″ — Viton / Silicon Carbide / Silicon Carbide (VIT/SIC/SIC)

Why this set

• Correct upper/lower pairing for 250CLC

• Hard SiC faces on the lower seal for abrasion and heat resistance

• Carbon/SIC upper for smooth running and dependable sealing

• Elastomers matched to duty: Viton (chemical/temperature) below, Buna-N (general hydronic service) above

Notes

• Verify your pump model and seal sizes (2-1/8″ lower, 2-1/4″ upper)
