12 Volt Pumps

Here's a post to revive from the Grimescene back in 1/07

Here are my experiences with 12V and 115V pumps

1) 12V Shurflo 1.8gpm 60psi. Weakest pump I have used. Painfully slow, does not draw well or shoot very far.

2) 12V Shurflo 1.5gpm 150psi Good pump. Good for decks, fences, trim around houses, small touch up roofs jobs while washing a house, pumps well through 200ft 3/8" hose. Too slow for entire roofs.

3) 115V Shurflo 3.3gpm 50psi. Ok pump, I used it a little while for roofs, much faster than 1.8 but I started getting into electrical problems, it kept shorting out, and tripping the breakers on customers houses when it got wet.

4) 12V Flojet 4.9gpm 40psi. Great pump, holds up very well, lasts a long time and another big difference going from the Shurflo 3.3gpm.

5) 12V Delavan 5.0gpm 60psi. As of 2007 the best 12V pump I have owned. Latest technology provides performance unheard of with 12V pumps until the new FATBOY came out recently. Again another step up from the 12V Flojet.

6) 12V Delavan 7.0gpm 100psi As of 11/08 the current best 12V pump available.
For serious full time roof cleaning, get the YAMADA KYNAR air pump Apple uses.

For those of you that have had problems with the 12V Delavan 5gpm 60psi pump, don't give up. Sometimes you just get a dudd, or lemon. My Dual Delavans last an average of about 8 months.

Great Post Mike.
We love our pumps
