Wow us belt guy's have been quiet over here.How about a type of poll?
How many guy's are set up with high pressure washers,and how many are set up with high volume(garden hose) type pumps. And if you have run both which do you prefer.

Garden hose, which is also my preference. I like it because it's easier to work with, and allows me to get in tighter spots, like the transfer.
The pressure washer is good for more serious cleanup, but if everything goes according to plan there shouldn't be any major messes. On the rare occasions that things get real messy, I take care of it baack at the shop.

| Funny you bring this up Terry I was just thinking how keep the pressure down to turn the pressure washer into a hose nozzle end. I prefer a regular hose for the same reason Fishbone stated just makes for an easier clean up. |

Use the pump that came on the truck, the little gear pump.

| Dan, get a larger nozzle for the tip, either a wide fan, or a higher GPM tip. (larger opening) |
If you can't fix it with a hammer....you've got an electrical problem. |

| Mine came with the high pressure pump. I like it for everything,except the transfer. I wonder if w9 yds could figure out a way to have both systems in place so I could have my cake and eat in too. Feel free to chime in Don. |

You can get quick-change tips, a larger tip will allow more flow and less pressure. I've seen some tips that are a 'dial' type, but then it's a lot bigger which may not be the best either.
As far as having your cake and eating, you'll have to rig-up a hydraulic diverter valve and put in a Hypro roller pump or another type. A Hypro requires a pressure refief valve that returns water to the tank to reduce the pressure. Then you can operate one pump or the other. |

Whatever you do, DON'T put a shut-off type nozzle on the pressure washer wand. When you shut it off, the pump will develop 2,000 PSI. Garden hose nozzles don't like that. Also, DO NOT try to use air pressure on the water tank. It is not a pressure vessel. Some owners have added mixer-type pressure tanks to their units. Rotec did this on some of the first ten they made. It wasn't a popular option, because it really added a lot of weight.
Telebelt pressure washers don't lend themselves to low pressure applications, because they only put out a few gallons per minute. The larger the nozzle orifice, the lower the pressure
My favorite low pressure/high flow pumps are the roller type, like a HYPRO. They operate at tractor PTO speeds (700 - 1000 RPM) http://www.hypropumps.com/en-us/Products/Pumps_Summary/Roller/
The output of the Telebelt accessory gear pump is known, so motor size can be calculated to give the needed RPM. Get a bracket to hold the motor and pump, a flex coupling, relief valve and some plumbing and you are set. You can power it with the same lines that power the pressure washer. I suppose you could also add a valve to select either the roller pump or the pressure washer.
The 7560N is the type of setup I'm talking about; not necessarily the size.

Ah, the old pressure/flow thing. Pressure washers are usually fixed displacement piston pumps. Larger nozzle diameters cause lower pressure but do not increase flow.

| The Hypro 7560N-GM30 is a nice little setup. It comes with a 7560 pump, a mounting bracket and a hydraulic motor. When the $4000 pump in the water tank went out on my old pump I replaced it with one of these and it worked great. |

| I use the pressure washer set up from Putz. It gets things clean faster and more thouroughly. I do not wash up in the transfer area on the job unless I have had a problem. It gets cleaned up and oiled before the pour and between pours. I only wash up there when I am at the shop or if I have had a particularly messy job. Best to try to keep things simple. |

Hypro's are so noisy at speed.Thinking of switching.
Anybody use a helical gear type from Albany pump ? |

I'd never heard of them before.
Not that a Hypro is any better, but how would these stand up to contaminants, given the close manufacturing tolerances?
