  • DESCRIPTION

    Single Spring Mechanical Seal 185C — 1-1/4″| PS-185

    185c single spring mechanical seal, PS-185 / 185 equivalent. Fits 1-1/4″ shaft with 1.875″× 0.437″ seat and Type N-11 (Type C/21) rotary head.

    Typical applications: Centrifugal pumps, mixers, and other rotating equipment.

    Key specs: Shaft size: 1-1/4″ single spring seal • Seat: 1.875″ x 0.437″ cup • Rotary OD: 1.787″ • Working length: 1.062″

    Design & construction:
    Crimped rotary head (Type N-11)—similar to industry Type C / 21; can also replace Type D / 2 with a simple spring change (in most cases). Electro-polished 304 stainless steel metal parts. Elastomeric bellows. Non-directional (independent of shaft rotation).

    Same seal, same dimensions — only the seal faces and rubber parts change. Most clean-water pumps take the Standard seal. Step up to an Upgrade if your pump runs hot, handles chemicals, or pumps gritty water.

    3 seal materials available — choose yours from the drop-down menu above.
    Seal Material Max Temp Choose This If
    Standard – Carbon/Ceramic/NitrileCAR/CER/NIT 200°F Clean water at neutral pH — HVAC, water transfer, pool and general-service pumps. This is the standard build.
    Upgrade – Carbon/Ceramic/VitonCAR/CER/VIT 450°F Your pump runs hot, or handles glycol, oils, fuels, bleach or other chemicals that break down standard Nitrile.
    Upgrade – Silicon Carbide/VitonSIC/SIC/VIT 450°F Gritty or dirty water, wastewater and slurry, or any pump where seals keep wearing out early. Hardest faces we offer.

  • PHYSICAL PROPERTIES

    T-N11/N22 Seal Heads

    Our T-N11/N22 type seal heads are designed with a reduced outer diameter, making them fully compatible with ANSI seal chamber dimensions. The rotary portion of our seal is typically smaller than the stationary seat, and can fit straight box bores where many other seals cannot.

    These seals are direct replacements for industry-standard T- C / 21 models 

    Note: The N11/N22 seal designs max shaft size is 2.25″. For larger shafts, please refer to our other seal types.
