current machine is 3600psi with 15 lpm but i have saw a machine with 3000 psi  pushing out 21lpm. What would give best cleaning on monoblock?

flow

[drive surgeon]

A good question but a lot is down to water supply feed. 21 litres requires a fast feed to tanks.

[drive surgeon]

We stick with 15 for this reason.

[wpclean]

Better to have it, and not need it, rather than to need it, and not have it 

[drive surgeon]

Just turn the revs down?

[BDCS]

So the 21 is best as you can throttle it back. 15 is 15 max

hi all   i operate a 200bar 30ltr a min machine
i have 2 sets of spinners for my fsc,s
1 spinner is fitted with 15ltr jets and 1 is fitted with 30ltr jets

Very true, bit like a car really better to have a bit in reserve then be flat-out and peaked but need that bit more.

[drive surgeon]

Good advice guys. What the pressure like on a whirlaway with 21 litres rather than 15 ? Does it take off??  Lol

[BDCS]

The pressure would be the same - just more flow. The extra flow makes work a lot easier.

[JSMC]

Link me up with decent FSC adequate for working with 21ltr pm

[drive surgeon]

So basically the whirlaway spins alot faster but gives same pressure? Oh well I guess I'm going to get a new machine then. So would 3 quarter throttle be about 15 litres a minute?

[drive surgeon]

Our 15 litre a minute machine is a 13hp honda g390 with inter pump. What would a 21 litre machine use? A higher honda engine?

Not necessary, Tech-Clean 21lt is still 390 gX, the engine can handle the larger pump.

[drive surgeon]

Ok thanks rog. Hope your well and busy

[drive surgeon]

So when you use 21 litres a minute rather than 15 does it feel like you are getting more pressure? Even tho it's just more flow?

Drive Surgeon, as Roger said the GX390 has a capability 13HP . A WS202 pump requires 10HP . So this machine is ideal to give you 21 LPM . I would suggest however that you will require a double inlet water feed to the pump for max performance from the pump . Ed

Gx 390 is not 13hp .The gearbox will need 1 hp. The pump needs 10hp. This is not ideal.

[Aqua Power Solutions]

Chris, we will have to agree to disagree ! Ed
