$543.40

The DANAU DBC-1814GA is a commercial-grade triplex plunger pump designed as a direct-drive replacement for heavy-duty pressure washers. Rated between 2610 PSI (180 bar) and 3600 PSI, with a flow rate of 4.0 GPM (15 L/min), it is engineered for durability, efficiency, and long service life.

Manufactured by Zhejiang Danau Industries Co., Ltd., this high-pressure pump is built for strength, durability, and reliable performance in heavy-duty cleaning applications.

It features a forged brass head for excellent corrosion resistance and structural strength, combined with an anodized aluminum crankcase that ensures efficient heat dissipation during continuous operation.

The pump is equipped with ceramic-coated stainless steel plungers, designed to reduce wear and extend seal life for improved long-term reliability.

A detachable and pressure-adjustable unloader valve with built-in detergent injector allows precise pressure control and easy soap application.

Designed for 13 HP horizontal gasoline engines (such as Honda GX390 type), the pump operates at 3400 RPM and fits a 1-inch hollow shaft configuration.

It also includes a sight glass for quick oil level inspection and uses SAE 15W-40 non-detergent oil with a splash lubrication system for proper internal lubrication.
