  • DESCRIPTION

    Scot 118.000.344 Repair Kit — JM-Frame Pump Seal Kit

    The Scot 118.000.344 repair kit is a direct-fit replacement pump seal kit for Scot JM-frame close-coupled pumps. This is the kit that covers the broad middle of the Scot line — Motorpump 50, 52, 53, 54, 55, 65 and 81 across JM145 through JM215 frames — replacing the seal and every wear part around it to restore performance and stop leaks. Built to OEM-equivalent standards or higher.

    What’s included

    • Mechanical seal

    • Shaft sleeve

    • Gasket & O-rings

    • Five stainless steel hard parts for long-lasting, corrosion-resistant service

    • P-80 Emulsion Rubber Lubricant

    Applications:

    Scot JM-frame close-coupled pumps run across commercial and institutional plant rooms — hot and chilled water circulation, heating and cooling loops, domestic water boosting, condenser water and general water transfer. The 118.000.344 is the service kit for the standard seal arrangement used across most of that range.

    • JM-frame pumps: JM145–JM215 frames

    • Compatible motor sizes: 50, 52, 53, 54, 55, 65, 81

    Note: Motorpump 57 and 57E use a different seal arrangement and take the 118.000.383 kit instead. Match by frame and motor size, and enter your nameplate details at checkout so we can verify the correct kit.

    Three kits available

    Same kit, same fit — the difference is the seal material inside. Choose your build from the dropdown above.

    • Standard – Carbon/Ceramic/Nitrile — ordinary hot water and chilled water systems

    • Upgrade – Carbon/Ceramic/Viton — hotter systems, glycol and chemicals

    • Upgrade – Silicon Carbide/Viton — gritty water and hard-wearing duty

    Which kit do I need?

    Most Scot JM-frame pumps take the Standard Kit. Step up to an Upgrade Kit if your system runs hotter, carries glycol or chemicals, or handles gritty water.

    Kit Max °F Choose This If
    Standard – Carbon/Ceramic/Nitrile 200°F Clean water at neutral pH — ordinary HVAC, booster and general water service. This is the standard build and matches the original kit.
    Upgrade – Carbon/Ceramic/Viton 450°F Your system runs hot, or carries glycol, bleach or other chemicals that break down standard Nitrile.
    Upgrade – Silicon Carbide/Viton 450°F Gritty or dirty water, process water, or any duty where seals keep wearing out early. Hardest faces we offer.

    Still not sure? Text a photo of your pump nameplate to 561-414-1046 and tell us what the system runs — we’ll tell you which build to order. No purchase required.
