Bell & Gossett Oil Tube L25201 Lubricant for Pumps and Motors, 2.5 Ounce

I have an old hydronic boiler (for radiators) that had not been oiled for quite some time. This worked perfectly to keep the pump running smoothly. I only wish that it came in a larger bottle because I used most of it up in a single application.

My pump has never been so quiet!

If you want a good long lasting oil, this is the stuff.

Great to have since I did not know that the circulator needed to be oiled. My bad completely, I have never oiled this pump in 12 years. A testament to this B & G series 100 pump that it was still running! Oil your pump and the technical manual is HS-105-SM-R4.

This is the manufacturer's oil for my Bell & Gossett pump that I use to heat my home. No issue with detergents or additives that could damage the pump.

This oil works great for my pump which was on it's last breath , The pump is on an outdoor wood fire boiler (heatmor) I had already purchased a pump for replacement so I would have one on site . But after putting this oil in the hole on the end of the pump it went silent , runs like a new one now .

Worked perfectly for my boiler.. running like a champ!

Maintenance.
