53BRD25 AAA Triplex Plunger Pump 3/4 Shaft 3400PSI max

The 53BRD25 is an AAA 3400 PSI Triplex plunger pump that minimizes engine load while delivering highly-efficient performance. This pump has a 3/4 in. hollow shaft that fits most horizontal shaft engines.

This AAA 53BRD25 triplex plunger pump comes equipped with Powerboost™ technology, providing a higher pressure output at the spray nozzle.

This pump is stabilized by dual oversized ball bearings. These help reduce the wear on the pump's components, provide friction resistance, and ensure longer-lasting performance in tough cleaning environments.

Important Service Notice:

Some AAA 53BRD25 Pumps were mislabeled from the manufacturer and are actually the 53BRD35 AAA pump. The 53BRD35 has a 1 in. shaft, while the 53BRD25 has a 3/4 in. shaft.

Please verify your pump before placing your order for a replacement pump or repair parts. One way to verify which pump you have is to look at the crankshaft diameter. If your AAA pump has a 3/4 in. crankshaft, it is the 53BRD25. If your AAA pump has a 1 in. crankshaft, it is the 53BRD35.

Make sure of the crankshaft size of your current pump before ordering replacement repair parts or a complete replacement pump.
