CANPUMP CF 3030 G triplex pressure washer pump — 3000 PSI, 3.1 GPM, external unloader, 3/4" horizontal gas shaft

The CANPUMP CF 3030 G is a commercial-grade triplex pressure washer pump delivering up to 3000 psi at 3.1 GPM with an easy-to-service external unloader and 3/4" horizontal gas shaft.

If you need a reliable replacement pump for a residential, prosumer, or light-commercial pressure washer, the CF 3030 G combines rugged materials and service-friendly features for consistent cleaning performance. It mounts to standard SAE J609 flanges and arrives prefilled with SAE 15W-40 oil, plus spare O-rings and a detergent tube to speed installation.

How durable is the CF 3030 G for frequent, heavy use?

This pump uses heavy-duty components built to withstand regular cycles: a forged brass manifold, anodized aluminum crankcase with cooling fins, a forged steel alloy crankshaft and ceramic-coated stainless plungers. German-made packing seals further extend service life while the triplex design reduces pulsation for smoother operation.

• Triplex plunger mechanism for reduced vibration and longer life
• Forged brass manifold and alloy crankshaft for strength
• Ceramic-coated stainless plungers resist wear and scarring
• German packing seals to minimize leaks and maintenance

Will it fit my pressure washer and engine setup?

The CF 3030 G is designed for compatibility with many gasoline-driven pressure washers that use SAE J609 mounting flanges and 3/4" horizontal shafts. It supports direct-drive engines up to roughly 6.5 hp and provides standard NPT inlet/outlet fittings for plumbing flexibility.

• Standard SAE J609 flange fits most direct-drive gas engines up to 6.5 hp
• 3/4" horizontal shaft for common consumer and prosumer models
• 1/2" NPT-F inlet and 3/8" NPT-F outlet for existing hose connections
• Ships prefilled with SAE 15W-40 oil to simplify initial setup

How does the external unloader improve maintenance and use?

The pump has a detachable external unloader that lets you adjust pressure, inject detergent, and filter feed water without opening the pump body. Because it is external and easily replaceable, routine service is faster and you can swap parts without removing the entire unit.

• Detachable, pressure-adjustable unloader for easy tuning
• Built-in detergent injector and water filter for cleaning flexibility
• External placement simplifies maintenance and replacement
• Unloader inlet accepts 3/4" garden-hose; outlet uses 3/8" quick-connect

What operating limits and specs should I consider?

Know the CF 3030 G’s performance envelope before pairing it: maximum pressure is 3000 psi at up to 3.1 US GPM, with a top speed of 3400 RPM. Observe inlet water temperature and pressure limits and use the specified oil grade to protect internal parts.

• Max pressure 3000 psi; max flow 3.1 US GPM; max RPM 3400
• Water inlet pressure 0–50 psi; max inlet temperature 122°F
• Oil grade SAE 15W-40 recommended; sight glass for quick oil checks
• Pump inlet 1/2" NPT-F, outlet 3/8" NPT-F for standard plumbing

Who is this for: The CANPUMP CF 3030 G suits homeowners upgrading older residential units, prosumers needing a dependable replacement, and small businesses that require steady cleaning power for driveways, decks, siding, vehicles and similar surfaces. If you want a rugged triplex pump with a user-serviceable external unloader and broad compatibility for 3/4" horizontal shaft gasoline engines, this model is made to be a straightforward swap-in and workhorse component.
