a 202 is 200 bar @ 21 litres per min
a 201 is 200 bar at 15 litres per min
With a 10 hp diesel I would go for a 201 (15 litre)
21 litres is better but running at 170 bar it won't quite have the 'cut' that you need for running a whirlaway on block paving for cuttingthrough moss etc
prices are around 560 brand new with a gearbox, (both 201 and 202 are the same prices
Matt, flow is determined by rpm, an 11hp honda petrol will run at the same speed as a 13 (around 3100 to 3500 rpm)
It's when you try to push 21 litres through it's correct jet (.65) when the engine (10hp diesel) will struggle and begin to stall, but by reducing the pressure by putting a large nozzle in .75 or .8 you will still get the flow but the engine won't be struggling as much so you will get the full 21 litres but at a reduced pressure
If you get me?
