  • Tsurumi EPT3-150YD mechanical seal, silicon carbide faces, Viton elastomers, cup seat included

    Tsurumi EPT3-150YD Mechanical Seal

    Tsurumi EPT3-150YD Mechanical Seal

    Item #SH-150YD

    Tsurumi EPT3-150YD Mechanical Seal

    An aftermarket mechanical seal for the Tsurumi EPT3-150YD, supplied complete with the cup seat — no separate seat to source. Built by Seal House with silicon carbide faces and Viton (FKM) elastomers.

    At a Glance

    • Fits: Tsurumi EPT3-150YD

    • Material: Silicon Carbide / Silicon Carbide faces, Viton (FKM) elastomers

    • Style: Cup seat

    Application

    EPT3 pumps work construction and site dewatering, sump and pit pumping, flood and storm water, and general trash duty — abrasive water carrying sand, grit and debris, often running unattended for long stretches. Silicon carbide against silicon carbide stands up to that abrasion, and the Viton elastomers hold up where nitrile softens.

    • Brand: Tsurumi

    • Pump model: EPT3-150YD

    • Series: EPT3 Series

    This is a Seal House build, not a copy of the factory seal — the face and elastomer materials may differ from what your pump shipped with. Silicon carbide against silicon carbide is the hard-face pairing and it suits the abrasive water an EPT3 works in. If you need to match the original Tsurumi specification exactly, call or text 561-414-1046 before you order and we will confirm what your pump was built with.

    Need Help Matching?

    Confirm your pump model from the nameplate before ordering. Not sure? Send a photo of the nameplate and the old seal to info@sealhouseusa.com, or call or text 561-414-1046 — our seal specialists will match it. No purchase required.

  • Tsurumi EPT3-50YD mechanical seal, 1-1/2 in. double seal, silicon carbide faces, Yanmar diesel build

    Tsurumi EPT3-50YD Mechanical Seal1-1/2 in. Double Seal (Yanmar Diesel Build)

    Tsurumi EPT3-50YD Mechanical Seal1-1/2 in. Double Seal (Yanmar Diesel Build)

    This is the replacement mechanical seal for the Tsurumi EPT3-50YD engine-driven trash pump — the Yanmar diesel build. It is a 1-1/2 in. double seal with silicon carbide running faces on both sides, the hardest face material we offer, specified here for long service life in rental and contractor duty. Built to OEM-equivalent standards or higher.

    Read this before you order: Tsurumi offers the EPT3 pump with more than one engine option, and the seal is not the same on every build. This seal is for the Yanmar diesel version. Check the engine plate on your pump before ordering, or send us a photo and we will confirm it.

    Applications

    • Tsurumi EPT3-50YD engine-driven trash pumps on the Yanmar diesel build

    • Rental fleet pumps that run long hours between services

    • Construction site dewatering, trench and excavation pumping

    • Gritty, sandy and silt-laden water, where softer faces wear out early

    • Flood response, storm clean-up and standing water removal

    • Agricultural and irrigation transfer with debris in the water

    Why this seal is built with silicon carbide

    Trash pumps run in water carrying sand, grit and solids, and that is what wears a seal face. Silicon carbide is the hardest face material Seal House stocks, and running it against itself on both sides of a double seal is the longest-lasting build available at this size. On a rental pump, where the machine goes out again as soon as it comes back, that is the difference between one service a season and three.
