    Can't help you my friend, everyone I know uses diaphram pumps, never used a trash pump set up.

    Considering trash pumps are designed for pumping water fast thru big hoses , not spraying sealer , you have a problem . You may want to consider buying a professional unit with a mechanical mixer , and a compressor with an air diaphram pump . You can then adjust the pressure and flow .
