Power Source and Pressure Comparison
Power Source
Product A, the Canpump CT 3510 GB, is a pump-only unit designed for gasoline engines. It requires a 24 hp engine with a 1-inch horizontal shaft and a G2 mounting flange. This setup allows for integration into mobile wash rigs or trailer-mounted systems. Product B is a complete electric assembly. It includes a 2 HP 120 V single-phase motor running at 1725 RPM. This ready-to-use design suits stationary setups or lighter jobs where connecting to a gas engine is not desired. You must choose based on your existing power infrastructure and mobility needs.
Maximum Pressure
The pressure difference is significant between these two models. Product A delivers a maximum pressure of 3500 psi. This high pressure is ideal for removing stubborn grime, heavy industrial dirt, or thick buildup from construction machinery and fleet vehicles. Product B provides 1500 psi. This moderate pressure is sufficient for routine maintenance tasks like washing cars, cleaning driveways, or maintaining siding and decks. If you need aggressive cleaning power for tough jobs, Product A is the clear choice. For general household cleaning, Product B offers adequate force without being excessive.
Flow Rate
Flow rate determines how quickly you can rinse surfaces. Product A boasts a massive 9.2 US gpm output. This high volume dramatically increases rinsing speed and productivity, making it excellent for large surface cleaning, road flushing, or water transfer applications. Product B offers 2.2 GPM. While much lower, this flow is standard for residential and light commercial use, providing a steady stream for car washing and patio cleaning. The 9.2 Gpm of Product A allows you to cover large areas much faster, but it requires a more powerful engine to drive it effectively.
Intended Use
Your cleaning tasks dictate which pump fits your workflow. Product A is built for commercial and industrial applications. It supports longer daily run times and is ideal for fleet washing, agricultural equipment, and industrial wash systems. Its gearbox drive reduces heat and vibration, extending life in heavy use. Product B is designed for residential and light commercial jobs. It is perfect for car washing, driveway cleaning, and siding maintenance. The electric motor makes it quieter and easier to set up for home use, while the lower pressure and flow are well-suited for delicate surfaces that might be damaged by higher settings.
Oil Requirements
Maintenance involves different lubricants for each unit. Product A requires SAE 80W-90 or higher gear oil. This specific grade is necessary for the integrated gearbox that reduces pump speed from 3400 to 1560 RPM. The gearbox mechanism protects the pump internals from heat and wear. Product B uses SAE 15W-40 oil. This is a more common engine oil type, which may be easier to source for standard maintenance. Both pumps are serviceable with available repair kits, but you must use the correct fluid to ensure longevity and proper operation of the internal components.
Choose the Right Pump for Your Needs
Fleet washers needing high volume rinsing
You need to rinse large vehicles quickly. This unit delivers 9.2 US gpm flow, which dramatically increases rinsing speed compared to lower flow models. The gearbox reduces pump speed to 1560 rpm, lowering heat and vibration. This setup supports longer daily run times and improves suction capability for mobile wash rigs.
Homeowners cleaning driveways or siding
You want a complete electric unit for light commercial or residential jobs. This assembly includes a 2 HP 120V motor and delivers 1500 PSI at 2.2 GPM. It is ideal for car washing, patio cleaning, and deck maintenance. The external unloader valve allows for quick pressure adjustments and easy servicing.
Mobile rig builders using gas engines
You are building a trailer-mounted system and need a pump-only unit. This model features a standard G2 mounting flange for direct installation on gasoline engines up to 24 hp with a 1-inch horizontal shaft. The forged steel crankshaft and anodized aluminum crankcase provide industrial reliability for demanding field conditions.
