Review: Great for use as a wash-down pump in a CNC machine - For many years, I've been tapping off my CNC machine's coolant sump pump for the wash-down hose. Anyone who has a CNC machine knows what I'm talking about. But sump pumps are really not designed for lots of pressure, and the wash-down has always been lacking in that department. On a whim, I picked up one of these pumps to give it a try. First thing I ran into was what others have mentioned, a 1/2 pipe thread fitting doesn't really screw onto the plastic fitting threads on the pump body. It goes on about one turn is all, if even that much. The thread pitch of the plastic is actually the same as 1/2 pipe thread, but it's not tapered. However, using a 1/2 pipe thread tap and some elbow grease, I was able to open up the inside of the 1/2 fip x 3/4 male hose end brass fitting (an off-the-shelf piece at Home Depot, SKU 894907). Wrapped some teflon tape onto the plastic and I was able to screw it about halfway on. Works good and doesn't leak. I'll include a picture. On the inlet side, I attached the included filter and then the included plastic 1/2 hose barb fitting, then a short piece of clear vinyl tubing to the sump. It only has to lift the coolant a few inches. Plugged it into the machine's "Coolant 2" plug, powered the machine on, turned on the coolant 2 function, squeezed the sprayer's trigger, and voila, great pressure! Not quite pressure washer level, but plenty to blast chips out of the far corners of the machine. Very impressed with the both the pressure and volume delivery, it's a massive improvement over the sump pump. The pump is very quiet, and kicks on as soon as I pull the trigger on the sprayer, and shuts off as soon as I release it. Really a slick little pump that solved my problem nicely. I can't believe I've gone all these years putting up with low pressure, when the solution was so simple and inexpensive. The life of the pump is still an open issue, but it has a 4 year warranty. If I get that out of it, I'll have my money's worth. If it dies before then, I'll update the review. But as of right now, five stars for this little pump.

## Questions & Answers

**Q: Will this pump work for a 12 plant drip emmitter system that requires 10 to 50 psi? If so do I need a pressure regulator?**
A: It has a limit pressure switch set at 45PSI.  We use a regulator to slow the flow.

**Q: does this pump accept standard garden hose connectors?Tks**
A: no, but you can buy adapter or do what I did and cut an old hose and slid over the pumps fitting with a clamp. Worked great.

**Q: Can this pump run for an extended period of time? 1-2 hours?**
A: Been using these for years on my water filtration system... I run it for 20-30 minutes at a time with a 15 minute break. The pump gets EXTREMELY HOT after this amount of time, so I always have a small fan blowing on it when in use. I have to replace the pump every 1-2 years as well. Be careful with the plastic part where the hose screws on... it breaks very easily , especially after months/years of use. Besides that it works well enough that I keep coming back for it!

**Q: Whats the max temperature this can pump**
A: The maximum temperature this pump can handle is 140° F. Any higher than that and the internals of the pump can be damaged over time.
