Anyone know where to buy spritzer pumps? Or will a cheap fountain pump from harbor freight do the job?
Thanks!

I would think a small cheap pump would do the trick since you're only pumping a small amount of water.

I would think a small pump should work just fine. I have seen people with Diamond Pacific units use aquarium pumps and they work great.

One of my cabbing machines just uses an aquarium pump. It works just fine.

What is the problem you have?  If you have Diamond Pacific ones that stopped working - they can be rebuilt for real cheap.  I keep planning to do a tutorial to show how so if that is the problem I may get out to the shop and take a few pictures to show how....   dancer5

I like constantly clean water so I use a swamp cooler pump in a 5 gal bucket of water.... fill it to the bottom of the pump.  Every now and then I pour a gal of water in it.  Last me for quite a while.

Phil, check the Diamond Pacific web site in there catalog. there units have a small brass unit that sets under the wheels and spritzes water on the wheel. They aquarium pump just provides the air to bubble the water through the brass unit which sets in the water in you pan below the wheels.
Like Michael said if you have a Diamond Pacific unit the pump is easy to rebuild. I have a pixie unit and have done it a couple of times.

Thanks all.

Yeah, I prefer always clean water too, but that's going to require a major refit of the Diamond speedster unit. Raise the top, so any fittings don't hit the wheels, drill some holes and install fittings, grommets, whatever, and the the risky part, drill some drainage holes in the cast iron base, then find a way to attach a drainage hose. Drilling old cast iron is always a big risk.
As this is all diamond, and just the polishing stages up to 3000, I think I'm OK with a spritzer unit, which I don't have. Gotta buy one somewhere. I do all the coarse grinding and shaping on a separate unit that has constant clean water via swamp cooler and buckets.
Thanks!

This discussion would benefit form clarification that the aquarium pumps, and the spritzer pumps are air pumps. The small fountain/pond pumps are water pumps. In using any water pump to deliver recycled water to the wheel, the pump needs to be robust to the rock grit in the water.

The reason fountain pumps don't fit under the wheel, is because there is only room for a brass head, which spritzes tray water upwards when submerged. The air passes through the head - not water.

Systems that deliver fresh or recycled water from overhead use water pumps. They need to be low volume (not gallons per minute like fountain pumps) and if using recycled water, they need to be rated for dirty water.

Or use a gravity drip system to wet the wheels. I think this is best because it uses fresh water (no grit to contaminate the wheel) and low cost. You do need a drain line to a bucket to catch the excess water in the drip tray though.

If you float the pump with styro or some other you are getting cleaner water off the surface because grit settles fast.

Now I do like DickB and gravity feed. Half a bucket with 1/4" pipe thread fitting screwed right into the plastic. Tubing drops down to a needle valve. I have a 5/16" hose as a coupler for the 1/4" hose after the valve so I can just plug and unplug the hoses to the different wheels. They fit tight enough so they do not leak.

Not so long ago there was quite a discussion about contaminating the different Nova wheels from the previous grit and how important it was to keep them clean.  I assume the Diamond units being discussed here have separate water supplies??   dunno
