Part Number: TT9111EBF
Category: Pressure Washer Pumps
Type: Direct-Drive Triplex Pump – TT9111EBF, 3.0 GPM @ 1500 PSI (1750 RPM, 5/8″ Right-Hand Hollow Shaft)

The TT9111EBF Triplex Pressure Washer Pump is a low-RPM, electric-duty direct-drive pump designed for systems that prioritize smooth operation, extended service life, and quiet performance. Rated for 3.0 GPM at up to 1500 PSI and engineered to operate at 1750 RPM, this pump is ideal for electric motor-driven pressure washers used in light commercial and residential environments.

Built with rugged triplex plunger construction and a 5/8″ right-hand hollow shaft, the TT9111EBF delivers reduced pulsation and cooler operating temperatures compared to high-speed pumps. Its lower RPM design significantly minimizes internal wear, making it a dependable OEM-style replacement for electric units that require long-duty cycles and consistent output.
