Comet Pumps Upgrade: Enhanced Replacement for Discontinued AAA 4 GPM Pressure Washer Pump
With the recent discontinuation of FNA Simpson’s AAA and OEM pump lines, we’re excited to offer an upgraded solution for your pressure washer needs. As the original manufacturer of the AAA 4 GPM pump, Comet now proudly offers the ZWD 4040 Triplex Ceramic Plunger Pump as a superior replacement. Typically priced at $342, this pump is a complimentary upgrade, giving you a $57 value at no additional cost.
The ZWD 4040 offers enhanced durability and performance:
- Commercial-Grade Italian Engineering: Made in Italy, the ZWD 4040 pump meets stringent commercial standards. Unlike the AAA pump, now produced in China, the ZWD 4040 is crafted for robust, lasting use.
- Improved Oil Capacity: With an 11-ounce oil reservoir, the ZWD pump runs cooler and longer, reducing wear even during heavy operation.
- External Bypass Hose: This feature minimizes wear and heat build-up, extending the life of the pump during bypass mode.
- Forged Brass Manifold: The ZWD’s fully forged brass manifold withstands extreme conditions, even accidental freezing, while ensuring high pressure and reliability over time.
Standard Features:
- Multi-function Unloader with Easy Start
- Thermal Relief and 3/8” Integral Bypass
