CANPUMP pressure washer pump CH 2830 G — 3/4" shaft, 2800 PSI & 3.0 GPM, brass manifold

CANPUMP CH 2830 G is a 3/4-inch horizontal-shaft axial cam pressure washer pump that delivers up to 2800 psi and 3.0 US gpm for heavy residential cleaning tasks.

The CANPUMP CH 2830 G replaces worn or underperforming residential pressure-washer pumps with a sturdy axial-cam design built for 3/4-inch horizontal shafts and engines up to 6.5 hp. It combines a forged brass manifold, anodized aluminum body with cooling fins and ceramic-coated stainless-steel plungers to resist corrosion and dissipate heat. With an integrated internal bypass unloader, detergent injector and German packing seals, this unit balances cleaning power with serviceability for driveway, siding, deck and vehicle washing jobs.

How much pressure and flow can I expect from the CH 2830 G?

The CH 2830 G is rated for a maximum of 2800 psi and a maximum flow of 3.0 US gpm, which suits most residential cleaning needs. Maximum RPM is 3400, and the pump accepts inlet pressures from 0 to 50 psi.

• Max pressure: 2800 psi
• Max flow: 3.0 US gpm
• Max RPM: 3400

• Mounting: SAE J609 standard flange
• Compatible engines: gasoline engines up to 6.5 hp
• Inlet connection: 3/4" garden hose

What durability and maintenance features are included?

Long-term reliability comes from a forged brass manifold, ceramic-coated stainless-steel plungers and anodized aluminum body with cooling fins to reduce heat build-up. The pump includes a dipstick for quick oil checks and German-made packing seals to minimize leaks and extend service intervals.

• Manifold: forged brass for corrosion resistance
• Plungers: ceramic-coated stainless steel for wear resistance
• Body: anodized aluminum with cooling fins
• Maintenance: dipstick oil check and premium packing seals

How does the integrated unloader and detergent system improve cleaning?

An internal, adjustable bypass unloader lets you control pressure smoothly without external plumbing changes, and a built-in detergent injector provides a 20:1 dilution for applying cleaning solution when needed. The assembly also includes a water filter to protect internal components from debris.

• Unloader: internal, pressure-adjustable bypass
• Detergent injector ratio: 20:1
• Protection: integrated water filter
• Outlet fitting: M22 (14 mm) for common hose adaptations
