    Polymer In-Line Electric Water Pumps

    Utilizing the same proven, patented brushless motor as the E558, this next generation pump offers super strong, light, engineered polymer resin inlet and outlets that are available in 1-3/4" or 1-1/4" for smaller displacement engines. It uses the o-rings to seal for reliability. With a 10,000 hour rating it is unmatched by any other electric water pump.

    Whether you are looking for additional water flow to cool your street rod or are racing in the 24 Hours of Lemans, you can count on EMP/Stewart Components products!


    Manufacturer's Part Number:

    Stewart Components has developed in-line electric water pumps with unique features and benefits. Weighing less than 5 pounds and measuring 6'' long with a 4-1/4'' diameter, these pumps have single speed flow up to 55 GPM.
    The electronic control box can be mounted remotely using the prefabricated harnesses sold separately. The pumps can be used alone in many applications or as a booster pump for vehicles that experience overheating problems in low RPM situations.

    Because mechanical water pump speed is directly linked to engine RPM, overheating can become a major problem while in parades, cruises, or stop-and-go traffic. An in-line booster pump solves this problem by working with the mechanical pump to create constant added flow to the engine block. These pumps have been proven to increase flow by more than 300% at idle.
