Well, I just purchased a Shurflo 2088-422-444 (US
equivilent?) as well as the aluminum heat exchanger
that fits the body of the motor (A perfect fit, I
might add.... I was told that it will Provide
continous use abilities. Motor does not over heat).
The reason I purchased the Shurflow is that I've got a
couple friends who are in the RV business and they ALL
stated emphatically that Flojet has a poor reputation
(The pumps fail) within the RV industry (The RV
industry here in the USA. I don't know about the rest
of the world...). Further, there is no heat
exchanger/heat sink for the Flojet pumps (Which could
be why they fail...) The pump cost me $62.95 US
dollars and the aluminum heat exchanger (Heat sink by
any other name) was less than $20.00. I hope the heat
sink works as advertised... I'll let you know.


The specs for this pump are:

Flow rate: 2.8 gpm (10.6 lpm)
Shut off pressure: pressure: 45 psi (3.1 bar)
Voltage: 13.7 DC
Amperage: 7.0 Max
Housing: Glass filled polypropylene
Valves: EPDM
Diaphragm: Santoprene
Warranty: 2 years
