Is anyone aware of a water pump designed (or adaptable) for use with a car/truck engine--while the engine is still in the vehicle? In other words, drive to location, hook up hoses/whatever, start the engine and you're pumping water for for drinking, irrigation, etc.? Thanks for any help!

Here are a couple search terms for you:
PTO pump
12 v pump.

A large alternator and an inverter would let you just plug in an electric pump. If it will run all those lights in the commercial, it will also run a pump. :)
Thanks! How large? I'm looking for something that will run itself until the fuel tank goes dry. In your opinion, given the same flow rate--would I get more time out of a PTO or electric pump?

Usually the PTO, but most vehicles don't have a power takeoff. Jeeps, tractors, some lawn tractors can have a PTO.

PTO driven pumps are usually fairly large. How much water are you needing? 12V may be the best for drinking water and light irrigation.

I actually do not yet know the flow rate needed. Water supply unlimited for practical purposes; likely surface water. Purpose is fire suppression. Extreme ambient heat a factor, so the fewer potential points of failure, the better--which makes me lean toward PTO. Set-up must be fast--minutes at most. Ideally it works when very wet, but not essential. Must be reasonably portable, and work with light truck passenger vehicle. I know there's a PTO winch for this vehicle, so I'm guessing a PTO water pump isn't too much of a stretch...

Thanks! There is a PTO winch application for this vehicle, so should be good on that score.

You may have to run a hydraulic pump with the PTO, then use a hydraulic motor to run the water pump. Sometimes there isn't enough room to install a water pump directly on the PTO.

Another idea, thanks! Some of those pumps do look pretty big...

You will need a pump with double bearings made for a non close coupled motor. Sometimes they’re called a pedestal pump. A normal close coupled electric motor/pump uses the motor’s bearings to support the pump.

These arewhat we use in water trucks. Run off of a pot and a drive line. Or a pot with a hydraulic pump and a hydraulic motor on the water pump. A Berkeley is a common water truck pump, but it’s a 500 gpm pump. I use 4x3 centrifugal pumps for mud drilling. I’m a dealer for MCM pumps and keep a couple in stock. They make them down to about 1 1/2 x 1”.

Seems like I’ve seen 2” pedestal pumps in the northern hydraulics catalog for a couple hundred dollars. These would be equivalent to the 5hp gas trash pump.

The Peterbilt I drive has two electric pumps, a low pressure feeding a garden hose, and a high pressure feeding a pressure washer gun. Not sure, but they might be using the trucks 24V system.
