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.
