Product review (4 stars): Aftermarket part  OK
This is an aftermarket part.  There are no Whirlpool markings on the pump or bag.  The one I received is Green plastic.  The Inlets / Outlets match perfectly in diameter and angle.  It also includes an extra set of shock mounts (I assume for different machines)  The impeller is 4 blade like the factory unit.  Plastic housing feels a little thinner than the OEM.  Given it was half the price compared to other vendors  (80 bucks) I hope this holds up.  Update report to follow.
