Questions and Answers
2 Questions
or Ask a Question
Can I pump diesel engine oil with a NMDP33-G35-50-12 without damaging the pump diaphram and valves? The pump will only run for a few seconds at a time then remain off for an extended time, then run again for a few seconds. ALSO what is the operating temperature range?
Answer This Question
This is a water pump, not an oil pump, and it is not recommended to pump diesel

Can this pump be mounted in any orientation?
Answer This Question
If it is installed vertically, it is best to have the pump head at the bottom.

Awesome pump, exceeded expectations.
This is no toy, it's seriously built well with a metal body, not like most of the pumps on eBay. It's Powerfully, better water pressure than my outside tap on mains pressure Fantastic!🙂

easy to install
used this pump in my camper. it does make some noise but not to bad. works great for the sink and shower lots of water pressure. you can turn on the power switch and leave it on pump cycles on when you turn a faucet on and runs as long as you are running water when you shut the water off the pump shuts off via the pressure switch on the pump. so far its working great but only had it for a short while

Excellent Purchase
Worked to help quiet the water system when utilizing the fresh water tank... I only use the city's water pressure in my RV just to fill up my Freshwater Tank... Keeping my Fresh water tank clean and not having to worry about the different park's flux awaiting water pressures... As of yet, I have no water issues in my RV.and the pump does not hammer any more...

Quiet, efficient Pump
In the RV it works great. Will supply all faucets with plenty of water. I am using as a backup just in case. It is loud as most pumps are, but then you know it is working. Good value pump!
