    It works better than the original pump

    I made a few modifications to the original safety shroud, installed the new pump, and it worked perfectly.

    Replacement pump

    Posted by Paul S Stanley on Jan 9, 2026

    The pump on my Campbell Hausfeld pump seized. This replacement pump was the perfect . It made economical sense to replace the pump. Living in Canada, even with the dollar exchange, it was less than 1/4 the cost of a new 60 gallon compressor. The pump has a few design changes from the original, but it installed without any need for adaptations.
