larger tips for more flow?

[Asbestos]

I have a 13 HP with a general pump that recommends a 4.5 tip so if I get a 5.5 or a 6.0 or whatnot. will this hurt my pump. I am looking for more flow and less pressure. A while back there was a thread about a 0 deg. tip drilled out to shoot chems.

The larger nozzle, will reduce pressure,
GPM / flow is controlled by the RPM and
rating of pump.

Example:

AR Pump model XWM2128 is rated at a
maximum of 4000 PSI @ 5.5 GPM at 1450 RPM
with a 5.5 nozzle it will deliver 4000 PSI at 1450 RPM
go to a 08 nozzle and you drop to around 1500 PSI at
1450 RPM as long as that pump is turning at 1450 RPM it will
not pump more than 5.5 GPM regardless of nozzle size however
if you go to a 04 nozzle your GPM would be reduced to 4 GPM at
4000 PSI.

Hope this helps! [hello]

The drilled out 0 nozzle just creates a low pressure situation so it will bypass and draw with a downstream injector. You see them the flat type are black. large opening so the bypass can be accomplished. I say always use a nozzle rec. for your output.

Mark, I use #30 0 deg tip 90% of the time (housewashing of course). Could this be the cause of failed seals? I've never allowed my pump to freeze and never allow it to run more than 2 or 3 minutes without squeezing the trigger. I've had to replace the seals twice within 200-250 hours. I don't mean to hijack Asbestos' thread...sorry.

Do you have a bypass to a tank? If not you mught consider a dump gun to keep the pump cool.

Bypass to a tank is always the best bet, but with many folks running portable units, that is not an option.

Use of a larger orifice nozzle will not cause any damage to a machine. The pump is rated for full open flow, so even with no nozzle, their would be no problem. The only need for a nozzle is to control spray pattern and to create a restriction to raise the psi.

A dump gun may work, but may also create to much water in the area as well.

Thanks! Your right, I run a portable unit w/no tank, but I think about that up-grade every time I lift the beast back into my van after a back-breaking day!

Here are a couple possible upgrades to think about:

For the cost and minimal storage, how about getting some ramps to wheel it in? Or as Mark says, go for an upgrade. All American would be my choice.
