Regarding peristaltic pumps
 

Just wondering what the lifespan of dosing pumps is? I have two pumps from reefdosingpumps.com tht now are having trouble turning when hosing is connected to them. They will turn no problem when there is no resistance. What's the problem here? Is there any maintenance I can do to help? These pumps are quite old now, both of them are over 5 years old. Do they need to be oiled or something????

Are the lines clear? No clogs?

yeah, the lines are clear, and replaced as well :(

The motors I would guess need to be replaced.

Oh really? So they just burn out after a while, eh? Not a great long term investment then, really.

I would email the co. and ask them.

Yes, I tried that, I am just waiting for a response. But thanks for the suggestion.

Well, you could try to oil the gears inside. That is assuming the electrical motor is ok

OK, I'll try that. What kind of oil or grease do you think would be acceptable for this purpose?

have they been in use for 5 years or just 5 yrs old?
