High performance after-market pump top for Xylem D5 series water pumps with an integrated reservoir. This top offers increased hydraulic performance (up to 15%) compared to the factory top. The EK-XRES Revo series features a fully rounded design thus offering greater usability, allowing installation at any angle within 360 degrees of rotation. A special rubber shock absorber is used to de-couple the the main pump body from the mounting clip for silent operation, free of vibration induced noise. Additionally, horizontal and vertical positioning are supported for easier tube routing possibilities.
