The VEVOR 4400 PSI pump is the clearest choice if you specifically want a pressure washer pump with a brass head: its listing identifies a one-piece forged brass pump head. The WOJET 4400 PSI model suits buyers seeking similar high pressure and flow, while the General Pump is a higher-flow option. For smaller engines, consider the WOJET 3400 PSI pump or Canpump triplex pump. Match shaft size, engine orientation, pressure, flow, and connections before buying.

VEVOR 4400 PSI Brass-Head Pump
This VEVOR pump is the most directly relevant pick for shoppers searching for a brass pump pressure washer. Its listing specifies a one-piece forged brass pump head, a 1-inch shaft, and maximum output of 4400 PSI at 4.0 GPM.
Best for: Buyers replacing a compatible horizontal-engine pump who prioritize a specifically stated brass head. The listing describes a standard SAE bolt pattern and names several Simpson MorFlex and Santoprene models as examples.
The pump also has a sight glass for checking oil level and appearance. Its reinforced plunger is described as wear-resistant. Limitation: Compatibility is not universal; verify shaft diameter, engine orientation, PSI, GPM, and inlet and outlet connections before ordering.
WOJET High-Flow 4400 PSI Pump
The WOJET pump is listed with 4400 PSI maximum pressure, 4.0 GPM flow, and a 1-inch shaft. Those figures make it a candidate for buyers seeking a high-output replacement pump, provided their engine and washer setup match.
Best for: Shoppers comparing high-pressure, high-flow pumps with a 1-inch shaft. It was selected because its stated output places it alongside the VEVOR option in the comparison.
Limitation: The supplied product information does not specify pump-head material or detailed compatibility. Do not assume it has a brass head; confirm material, mounting pattern, and connections with the seller if those details matter.
General Pump TSF2021 Triplex Pump
The General Pump TSF2021 is listed for 8.5 GPM at 3600 PSI, with a 1750 RPM rating and 24 mm solid shaft. Its stated flow is higher than the other pumps in this selection, making it a distinct option for buyers who need high water volume.
Best for: Buyers whose equipment is designed around this pump’s flow, pressure, RPM, and shaft specifications. It was included to represent a high-flow triplex option rather than a standard small-engine replacement.
Limitation: The supplied details do not identify the pump-head material or provide mounting and connection information. Check the complete equipment requirements before choosing it, especially if you need a brass head or a direct replacement.
WOJET 3400 PSI Everyday-Cleaning Pump
This WOJET axial pump is rated at 3400 PSI and 2.5 GPM and is designed for a 3/4-inch shaft. The listing describes use for tasks such as washing cars and cleaning driveways, fences, and other outdoor areas. It names multiple engine families and models as potential fits.
Best for: Owners of a compatible 180–225 cc engine who want a replacement for routine residential cleaning. The hand-adjustable unloader is designed to let users change pressure without a wrench.
Limitation: Its pressure and flow are lower than the 4400 PSI, 4.0 GPM options. Confirm the exact engine model and connections; its garden-hose inlet and M22 outlet may not match every setup.
Canpump CF 3030 G Triplex Pump
The Canpump CF 3030 G is a triplex plunger pump rated for 3000 PSI and 3.1 GPM, with a maximum speed of 3400 RPM and a 3/4-inch shaft. Its listing describes an SAE J609 mounting flange for horizontal-shaft gasoline engines up to 6.5 horsepower.
Best for: Buyers seeking a triplex replacement or upgrade for a compatible smaller gas-powered washer. Listed connections include a 1/2-inch NPT-F inlet, 3/8-inch NPT-F outlet, garden-hose unloader inlet, and quick-connect outlet.
Limitation: The supplied listing does not identify a brass pump head. It also specifies a maximum inlet temperature of 122°F, so account for that limit when planning water supply.
Buying Guide: How To Choose A Brass Pump Pressure Washer
Does the pump actually have a brass head?
Check the product specifications for the pump-head material. Of these five listings, VEVOR explicitly describes a one-piece forged brass head. The other supplied product details do not establish that their pump heads are brass, so ask the seller before buying if brass construction is essential.
Which specifications must match?
Compare shaft diameter, engine orientation, mounting pattern, PSI, GPM, and inlet and outlet connections. A pump can have suitable pressure ratings yet fail to fit the engine or hoses. Use the current pump and engine model information to check each measurement.
Should you choose axial or triplex?
The WOJET 3400 PSI model is identified as an axial pump and is aimed at everyday cleaning. The Canpump and General Pump are identified as triplex pumps. Compare the intended duty, engine specifications, and required output; the product data alone does not establish that every triplex pump is a suitable upgrade for every washer.
Is higher PSI always better?
No. Match pressure and flow to the washer’s engine and cleaning needs. The listed pumps range from 3000 to 4400 PSI, while flow ranges from 2.5 to 8.5 GPM. Choosing based only on the largest PSI figure can lead to a mismatch.
Frequently Asked Questions

The VEVOR 4400 PSI pump listing specifies a one-piece forged brass pump head.
What does GPM mean on a pressure washer pump?

The General Pump TSF2021 has the highest stated flow at 8.5 GPM, with a listed pressure of 3600 PSI.
What should I verify before ordering a replacement pump?
Check engine orientation, shaft diameter, mounting pattern, pressure, flow, and all water and hose connections. Also verify pump-head material if brass construction is required.
