After 4 years of faultless operation the low pressure pump on my Spectra watermaker
is finally playing up.
These pumps do wear out out and I think its given very good service
considering it has been run every second day continuously.
I have a spare pump, but would like to repair this one.
The problem is the pump motor
stops completely. There is still 12v to the input terminals and the cooling
fan is running.
Wriggling the input wires where they enter the motor
restores normal operation.
My guess is the brushes
have become carboned up, or possibly there is a break in the wire as it enters the motor.
My question is does anyone know the brush size for this motor? Or has anyone done a similar repair?
It is a Surflow 8008-943-839 diapragm pump It similar to the freshwater pump (the motor is identical) as used on many boats
Fitted to Spectra Ventura 150.
