TOOLCY Pump Spec Comparison

Maximum Pressure

Edge: TOOLCY 4300 PSI Triplex Pump

The TOOLCY 3400 PSI Triplex Pressure Washer Pump delivers up to 3400 PSI of cleaning force. This model includes an adjustable pressure unloader, allowing you to dial settings from 2600 PSI for gentle tasks like car washing, up to 3400 PSI for tougher concrete cleaning. The TOOLCY 4300 PSI Triplex Pump offers a higher maximum output of 4300 PSI. It recommends a working pressure of 3400 PSI at 3400 RPM for longer pump life. This adjustment feature lets you reduce pressure for idle engine operation, lowering noise levels. The higher peak pressure of the 4300 PSI model provides more raw power for heavy-duty commercial or residential jobs where maximum force is required.

Flow Rate

Edge: TOOLCY 4300 PSI Triplex Pump

Flow rate determines how much water moves through the system per minute, affecting cleaning speed. The TOOLCY 3400 PSI Triplex Pressure Washer Pump moves 3.0 gallons per minute. This flow is suitable for standard residential tasks on driveways, decks, and fences. The TOOLCY 4300 PSI Triplex Pump significantly increases this to 4.2 gallons per minute. Higher flow rates rinse debris faster and reduce the time needed to cover large surface areas. This difference means the 4300 PSI model cleans more efficiently on wide areas like sidewalks and large patios. If you prioritize speed over raw impact force, the higher flow rate of the second pump offers a practical advantage for daily maintenance work.

Shaft Size

Edge: TOOLCY 3400 PSI Triplex Pressure Washer Pump

Shaft size is critical for mounting the pump to your engine. The TOOLCY 3400 PSI Triplex Pressure Washer Pump features a 3/4 inch shaft. It is designed for engines ranging from 6 to 8 HP with displacements between 180 and 225cc. It fits common models like the Honda GC190 and Simpson 90030. The TOOLCY 4300 PSI Triplex Pump uses a larger 1 inch shaft. It is built for more powerful engines, typically 9 to 15 HP with displacements from 270 to 420cc. It fits larger engines like the Honda GX340 and GX390. You must match the shaft size to your existing engine. This difference prevents compatibility with smaller residential engines if you choose the larger shaft model.

Included Nozzles

Edge: TOOLCY 3400 PSI Triplex Pressure Washer Pump

Nozzles determine the spray pattern and pressure intensity for different surfaces. The TOOLCY 3400 PSI Triplex Pressure Washer Pump comes with a complete install kit that includes five spray tips. These cover 0, 15, 25, 40 degree patterns, plus a soap nozzle. This variety allows you to switch instantly between spot cleaning, general washing, and applying detergents. The TOOLCY 4300 PSI Triplex Pump description does not list included nozzles or spray tips in its provided specifications. While it includes a quick connect output, you may need to purchase nozzles separately. The first pump offers immediate usability with a full set of accessories for various cleaning tasks right out of the box.

Water Temperature

Edge: TOOLCY 3400 PSI Triplex Pressure Washer Pump

Pressure washer pumps are often rated for specific water temperatures to prevent damage. The TOOLCY 4300 PSI Triplex Pump explicitly states it is for cold water use only. This restriction protects the internal seals and components from heat damage. The TOOLCY 3400 PSI Triplex Pressure Washer Pump data does not specify a water temperature limit. Without explicit confirmation, you should assume standard operating conditions. However, the clear warning on the 4300 PSI model highlights a strict limitation. If you ever plan to use warm water for grease removal, this pump is not suitable. The first pump lacks this explicit restriction in the provided data, making it the safer choice if temperature limits are unclear.
