Help with Sta-Rite Pump

Hi everyone. Looking to get a rebuild kit for a STA-RITE HP6F3 pump for my WW HV. I can't find any information on this pump since I believe it was made for WW? anyone ever re-built one. It is just a 1.5 hp three phase booster pump. If so where did you get the repair kit.
Thanks,

Vic
 
Has anyone ever found a place to buy an overhaul kit for this pump? I'm usually pretty good at finding what I need on the internet, but coming up short on this one....
 
Thanks Waxman. How did you determine you needed to change out your pump? For me, I have replaced regulators and inlet pressure is ~60 PSIG, but I can't get above 120 PSIG on my manifold. The WW manual says that LP1 and LP2 should be 200 PSIG, so I assume that my impellers are likely worn out, but I don't want to take the pump apart to check if I don't have any spare parts. I thought about doing a deadhead test, but again, afraid to do that and risk damage without having any spare parts on hand. I work for an oil refinery and have access to repair the pump in-house as long as I can source the parts, so if there's a way I can easily save a grand, I wanted to try and go that route first. Unless someone else has found a source for a rebuild kit though, it's looking like my only option is a new pump.

Did you buy the exact same pump, or did you get a more readily available pump?
 
I think my original pump was a Sta Rite and I replaced it with a Dayton. Mine was a solution pump for my old automatic some years ago. It just stopped working so I knew it needed to be replaced.
 
Hi I tried the kit, be careful removing the impellers from packaging ( kinda came apart in our hands) worked fine ultimately gave us a couple more years before replacing pump
 
Those Sta-Rite pumps are very well made. Typically the pump doesn't go out unless it's starved for water. They have plastic impellers that can melt within seconds of running dry. Even if it never runs dry, the impellers can be damaged by low inlet pressure over time but also dead heading will damage them. Replacing the pump stack and the mechanical seal are both pretty easy with some practice and the right tools. You just have to take your time and don't damage the stainless sleeve (which is very easy to do). I can get rebuild kits for Flint & Walling, Sta-Rite, and Goulds booster pumps if y'all need any. The Sta-Rite pumps are one of the best but Goulds pumps use stainless steel impellers which are much more durable than the plastic ones so they are worth the extra $$.

Any opinion on F&W? I'm getting ready to buy one for replacement. It didn't last as long as I expected but the regulator was circulating the water right back to the intake which may have contributed to premature failure. . I have since corrected that.
 
I have extensive experience with Flint & Walling. That's what we use on our entry level ROs that we build. They use plastic impellers so not as durable but other than that they work very well.
