This is a brand new Whirlpool-made Genuine FSP high-flow pump. This pump fits most direct drive washers made by Whirlpool under the different brand names, like: Whirlpool, Roper, Estate by Whirlpool, Kenmore, Kirkland Signature series (Costco), among others... This will not replace normal-flow pumps, it is model-specific.
The pump outlet is about 1 3/4" and has a flapper (check valve) on the outlet.
