Who it fits
Good fit for
This pump suits owners of General Pump T-47 Series units who need a direct replacement. If your original pump failed, this part matches the 3500 PSI and 4.5 GPM requirements. It fits setups using a 1125 RPM engine with a 24mm shaft. DIYers who prefer to maintain their own pressure washer frames will find this a viable swap. Ensure your existing engine and wand system align with these specs before purchasing.
Who should skip it
Skip this option if you need a complete pressure washer system. This listing does not include an engine, frame, wheels, or wand. You must source those components separately. It is not suitable for beginners seeking an all-in-one unit. If you require a ready-to-use machine without assembly, look elsewhere. Also, verify your shaft size is exactly 24mm. Mismatched shafts will prevent proper installation and operation.

Key specs explained for TS1811
Maximum Pressure: 3500 PSI
This value indicates the highest pressure the pump can generate. You will use this force to strip away tough grime, oil, and paint from hard surfaces like concrete driveways or brick walls. A rating of 3500 PSI places this unit in the heavy-duty category. It is suitable for serious cleaning tasks that lighter residential washers cannot handle. Ensure your hoses and wands are rated for this pressure to avoid damage during operation.
Maximum Flow Rate: 4.5 Gallons Per Minute
Flow rate measures the volume of water moving through the pump each minute. Higher GPM values rinse debris away faster than lower ones. At 4.5 GPM, this pump provides strong rinsing power. It helps you clean larger areas more quickly than units with lower flow rates. This spec works alongside pressure to determine overall cleaning speed. You will notice a significant difference in efficiency when washing large decks or fences.
Max Pump Speed: 1125 RPM
Revolutions per minute define how fast the pump internals move. This speed is optimized for durability and consistent performance. It is not a high-speed unit, which often means longer component life. You should match this speed with a compatible engine or motor. Using an incompatible drive can cause premature wear. This specification is critical when replacing a pump on an existing pressure washer frame or trailer.
Inlet: 1/2” FPT | Outlet: 3/8” FPT
These fittings determine how you connect hoses and water sources. FPT stands for Female Pipe Thread. You need compatible male-threaded hoses and connectors for both the water supply and the high-pressure output. The 1/2-inch inlet allows sufficient water volume to feed the pump. The 3/8-inch outlet is standard for many pressure washer wands. Verify your existing hose threads match these sizes before installation to ensure a leak-free seal.
Shaft: 24MM Solid Shaft
The shaft connects the pump to the motor or engine. A 24-millimeter solid shaft requires a specific coupling or pulley system. You must ensure your power source has a matching shaft diameter. Using the wrong size will prevent proper installation and cause vibration or failure. This dimension is a physical constraint. Check your current pump or motor shaft size carefully to guarantee compatibility with this replacement part.
Design and build of TS1811 pump
According to the listing, the KSQOON TS1811 is a bare pump replacement unit. It is engineered to fit General Pump T-47 Series models. The unit features a 24mm solid shaft. This specific shaft size is critical for compatibility with your existing engine or motor assembly. You must verify that your current setup matches this dimension before installation. The pump does not include an engine. It is shipped without engine oil after factory testing. You need to add the correct oil before you can use it. This design choice means you are replacing only the pump mechanism, not the entire power unit.
The inlet connection is a 1/2-inch FPT fitting. The outlet is a 3/8-inch FPT fitting. These standard thread types allow for common hose connections. The maximum flow rate is 4.5 gallons per minute. This volume supports consistent water delivery for cleaning tasks. The maximum discharge pressure reaches 3500 PSI. This pressure level handles heavy-duty grime removal on durable surfaces. The listing notes that you should carefully check the physical picture on the link. This step ensures the pump suits your specific pressure washer model. The build focuses on functional replacement rather than aesthetic features. You get a direct swap part for your T-47 series machine.
Setup and everyday use guide
Setting up the KSQOON TS1811 requires careful attention to mechanical compatibility and fluid preparation. This unit is a bare pump, meaning it does not include an engine or motor. You must pair it with a compatible power source that matches the required 1125 RPM speed. The listing specifies a 24mm solid shaft, so your drive system must align with this exact dimension to ensure proper rotation. Before you install the pump into your General Pump T-47 Series pressure washer, you must add engine oil. The manufacturer ships the unit without oil after factory testing. Skipping this step can cause immediate internal damage during your first use. Once installed, connect your water supply to the 1/2 inch FPT inlet. Attach your high-pressure hose to the 3/8 inch FPT outlet. The pump is rated for a maximum flow rate of 4.5 gallons per minute. This volume ensures consistent water delivery to maintain the stated 3500 PSI output. During daily use, you will rely on this steady flow to clean large surfaces efficiently. The solid shaft design provides direct power transfer, which is standard for heavy-duty applications. Always verify the physical dimensions and shaft size before installation to prevent fitment issues. The TS1811 is built for replacement purposes, so ensure your existing frame and mounting points support this specific model. Regular maintenance includes checking oil levels and inspecting seals for leaks after extended operation periods.
Before You Buy This Pump
Before you buy this replacement pump, you must verify exact compatibility. The TS1811 fits General Pump T-47 Series units only. It requires a 24mm solid shaft. Your current engine must match the 1125 RPM speed. Check the inlet and outlet ports. The inlet is 1/2 inch FPT. The outlet is 3/8 inch FPT. Mismatched fittings will prevent proper installation. You also need to add engine oil before first use. The unit ships without oil after factory testing. This bare pump does not include a motor or engine.
