Is there a rule of thumb when sizing compressor CFM on self-service bays? Looking to size a compressor for an eight-bay self serv (no automatics).

What a mess, was the back end of the pump damaged? So what is the consensus here; pop-off valve, thermal valve, or both?

If your Regulator is working properly why do you need a pop off valve(I assumed you are referencing a pressure relief valve)? The regulator will just bypass the water back to the pump inlet In the event of a clogged tip.

The idea was to protect the pump in the event the tip became clogged. However, since I'm using regulators, I do not see the point in installing pressure relief valves. In the event a tip becomes clogged, the water will circulate through the regulator back to the pump inlet. There may or may not...

I spoke with Cat technical support. They recommended that instead of using a thermal relief valve it would be better to use a pressure relief valve. In the event a tip becomes clogged, the increase in pressure should open the pressure relief valve allowing cooler water to enter the pump. We run...

Yes, hot water soap and wax. Why do you ask? Does it make a difference? My previous plant was gravity fed for all functions and did not have thermal relief valves. Over the years, I had numerous plugged tips but never had any damage to the pumps (General).

I’m rebuilding a pumping plant and replacing all the high pressure pumps. The rinse cycle is pressure fed and the high pressure soap and wax are gravity fed. How effective would it be to install thermal relief valves? I was thinking that they would be effective on the pressure fed cycle but...

I recently installed two new 5cp2021 pumps on a seven bay stand. The two new 5cp pumps are so much louder than the other five pumps I wondering if there is a problem. Is it normal for cat pumps to be noisy during the break in period? Im also wondering if the 310 pumps are better than the 5cp2120...

I need to splice several fifteen conductor 18ga stranded cables in one junction box. With so many different connectors available, it is difficult to find which one would be best for the job. Can someone make a recommendation on the best connector to use?

Just throwing out an idea. Is your pre authorization set higher than your most expensive wash?

I was thinking of using this stainless manifold for a direct-fed rinse application. The stainless pipe has a 1-inch opening on the inlet and the outlets are 3/8. I will be configuring this for 7 bays, cat 2120 pmps, 3HP motors, and 2505 wand tips. Additionally the high-pressure soap and wax will...

Are you saying that the pump has two inlets, one for hot one for cold? Their online brochure only shows one inlet for rinse the other inlet is for the regulator bypass. Hence the confusion.

What am I missing, it seems like the rinse tank outlet is directly connected to the pump inlet.

I was looking at a Carolina Pride brochure and it appeared that they use a hyrominder to fill their rinse tank. Is this correct or am I missing something? Also, it appears that they only use one storage tank for all wash related functions. If this is the case, then I presume that the entire wash...

Is it worth the time and effort to change the bearings on twenty year old 3 hp Baldor motors? Replacement motors are around $1000 and a set of replacement bearings cost around $20. The motors are currently installed on a plant that I am rebuilding and will put into service so it would be ideal...

My knowledge regarding Dilling & Harris equipment is very limited. Was the Extreme series one of D/H better pieces of equipment? In terms of an equipment upgrade, would it be decent choice? I have no documentation and any info or opinion on this equipment would be appreciated.

that is exactly what I was trying to say. I would imagine this works for lower pressures but may prevent the plunger to open at some elevated pressure.

Is this because you are applying pressure in the same direction as the solenoid plunger spring and not against it?

LOL, You must be kidding!
