Our take
If you're in the market for a heavy-duty replacement pump, this BFO triplex unit offers impressive specifications. The 4000 PSI and 4.0 GPM are indicative of professional-grade cleaning power, suitable for demanding tasks. Its broad compatibility with Honda GX270, GX340, and GX390 engines makes it a versatile option for many existing gas pressure washers. It's important to verify the 1” hollow shaft requirement for proper fitment.
