VEVOR high-pressure washer pump, 19 mm horizontal triple-piston pump, 227 bar pressure, 9.5 L/min flow rate, replacement kit with 5 nozzles, compatible with Simpson MorFlex 40224, 40225, 40226, Santoprene

Features and Details

High-efficiency cleaning power: The pump in our high-pressure washer delivers water pressure of up to 227 bar with a maximum flow rate of 9.5 L/min, ensuring quick completion of tasks — from household cleaning to light industrial tasks. (Recommended operating pressure: 179 bar, to ensure optimal performance and extend the pump’s service life.)

Durable, long-lasting design: Thanks to advanced anodizing technology, the pump’s surface is coated with a hard protective layer that significantly improves resistance to corrosion and wear. The pump is designed for long-term operation and delivers reliable performance for up to 500 hours of continuous use.

Equipped with a pressure regulator: The pressure can be precisely adjusted to match the engine's operation to achieve optimal performance for any cleaning task. The pressure can be easily reduced during short breaks by switching the engine to idle, thereby lowering the noise level and extending the equipment’s service life, ensuring more comfortable operation.

Wide compatibility: With its standard SAE bolt pattern, this pump is compatible with a variety of horizontal-engine high-pressure washers, including Simpson MorFlex models 40224, 40225, 40226, and the Santoprene model 41182. To ensure full compatibility, the motor orientation, pressure, flow rate, motor shaft diameter, and pump inlet/outlet connections must match.

Easy maintenance: The built-in oil level sight glass allows you to easily check the oil level without disassembling the unit, allowing you to detect low oil levels or contamination early on to keep the pump in top condition. To ensure long-term efficiency, it is recommended to change the oil every 60 operating hours.
Note: This replacement pump is intended for use with cold water only.

This improved triplex positive displacement pump provides a more stable and powerful pressure output compared to traditional single- or double-displacement pumps. Each pump cycle ensures a consistent pressure level, reducing pressure fluctuations and making cleaning more efficient and productive.

The simplified startup process and enhanced safety features make operation easier and safer. Our pressure washer pump lets you focus on the task at hand, increasing productivity and satisfaction.

Equipped with a variety of nozzles and a complete set of installation accessories, this replacement pump for a pressure washer adapts to various cleaning tasks and environments, increasing its versatility and ease of use.

The oil level sight glass not only shows the amount of oil, but also allows you to check the oil’s color and clarity. If the oil looks cloudy, has changed color, or contains impurities, this indicates that the oil may need to be changed to ensure optimal lubrication.

Suitable for intensive and demanding use, the performance advantages of this replacement pressure washer pump ensure higher productivity and reduce downtime. Excellent durability and a low failure rate mean less maintenance for long-term users, making it a smarter choice.
