Title: Ninja 135 psi
Post by: MHA on July 10, 2012, 12:07:51 am
I have ninja 135 psi with 2 vacuum motors. Can I upgrade it with Shurflo pump 150 psi by-pass induction motor without any other change ?

Id say yes ,  as long as long as it physically fits , chunky looking motor  , looks like a good pump .

This Aquatec is the most powerfull of the small diaphragm type pumps i'd say , u could probably import for the same price as the shurflo ... as an option .

but the shurflo is brushless , so should be trouble free for a long time .

---- so long as you never switch it on with pressure in the pipes.

what would happen then  ?  :)

i would guess as it doesn't have a capacitor fitted  it would have a large start resistance so might blow the fuse.

 Dunno , the thing on top looks like i could hold the cap , looks to have a back mounted fan too ..

An induction motor will not start with a load on it (ie pressure in the system to stop the pump bit.)
The old type of rectified brush motor will start with a load.
An induction motor will sit there and get very hot and burnout.

 wouldn't the internal bypass release the pressure ..
 I really don't know , just guessing ..

An internal bypass is a pressure regulator in the pump head set to the design maximum of the pump. When the pump stops the pressure will remain until it leaks slowly away through the internal inlet/outlet valves.
A 135 psi pump will 'blow' at 135psi. If there was not a relief, the pressure would increase until either the pump body broke or more likely the motor would stall and burn out. It is like a safety valve where the blown water is recirculated.
It is unlikely that 135 psi will be obtained at the jets when the valve is opened. My twin jet wand gives around 95psi spraying and 135 static. With bigger or worn jets this will fall.

does this mean 150 psi sprayed about 110-115 psi but work fine ?
