Pump specification and fit

The VEVOR QXB-5 is a horizontal triplex plunger pump with a 1-inch shaft rated for 4200 PSI maximum pressure and 4.2 GPM flow. It is designed as a direct replacement for Simpson MorFlex 40224, 40225 and 40226 models and pairs with 13-15 HP engines for residential or light industrial cleaning tasks.

Thermals noise and power

The pump is engineered for up to 500 hours of continuous operation before major service, with a recommended working pressure of 3400 PSI to reduce mechanical stress. A built-in pressure regulator allows the operator to lower output during pauses, which cuts engine load, noise and wear while idling.

Bundled kit contents

The package includes five quick-connect nozzles, a cleaning pin, a siphon tube with filter, flat key, mounting hardware, oil level gauge and O-rings. These items enable immediate installation and let the user select spray patterns, maintain the pump and draw detergent without purchasing separate accessories.

Questions about this item

How do I mount the QXB-5 pump on a horizontal-shaft engine and which step is often missed?

Bolt the 1" shaft to the engine using the four hex bolts, spring washers and flat washers supplied; fit the flat key into the keyway before tightening — this key is the step most installers forget.

What routine upkeep does the pump need and which parts wear first?

Check the oil level gauge before each session and refill as required; the six O-rings and five nozzles are the consumables that will need replacement over time.

What is the first limit reached during long runs at full output?

The pump is rated for 500 hours of continuous use; sustained operation at the 4200 PSI maximum will reach that service-life limit before thermal or pressure cut-outs activate.
