TX1812E179 Triplex Pressure Washer Pump – 3.8 GPM @ 2000 PSI, 1750 RPM, 1-1/8″ Hollow Shaft

Part Number: TX1812E179
Category: Pressure Washer Pumps
Type: Direct-Drive Triplex Pump – TX1812E179, 3.8 GPM @ 2000 PSI (1750 RPM, 1-1/8″ Hollow Shaft)

The TX1812E179 Triplex Pressure Washer Pump is a low-RPM, electric-duty pump engineered for systems that require higher flow with smooth, long-lasting performance. Delivering 3.8 GPM at up to 2000 PSI and operating at 1750 RPM, this pump is ideal for electric pressure washers used in light commercial and professional cleaning environments where durability and consistent output are essential.

Built with rugged triplex plunger construction and a 1-1/8″ hollow shaft, the TX1812E179 runs cooler and with less vibration than high-speed pumps, significantly reducing internal wear. Its low-speed design extends seal and bearing life, making it an excellent OEM-style replacement for electric-driven units that operate for extended duty cycles.
