Cracked pump

I just tore into one of my tfs2021 general pumps to figure out what I needed to order to get it back up and running. I couldn't find anything wrong with it. So I put it back together and hooked it up to the shop hose. The dam thing has a cracked head. It's on the low pressure side so I think it is fixable. Have any of you tried to repair a cracked head?
 
I've never tried to fix one, but a good welder should be able to repair it. It would need to be filled inside and out, then rethreaded. Otherwise, it'll suck air up the crack.
 
Russ, the TSF2021 is rated at 3600 psi max fro the manufacturer.
From your experience what is a sustained pressure "above" 3600psi if any, that this pump maybe successfully run at without excessive repairs or catastrophe.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
 
I have been thinking about running one at a higher rpm to get more gpm. The pump that has a cracked head has lasted a long time at 2,500 psi. It just couldn't handle 25 degrees. LOL
 
Since it is on the inlet side, I say JB weld. ;) You never know, it might work. Besides, it is awful hard to weld brass.

I would not recommend operating the pump outside the manufacturer's limits.

How much more rpm?, I hate having to run my TSF at 1750rpm, I really like the KE series from general Pump 8 @ 4350psi @1450 rpm, but for the price I could replace 4-5 tsf's
 
well last night I was bored and decided to see how well black gasket maker would work on the crack. I put it on the inside and outside of the crack. Hooked it up to water today. It seems to have worked. LOL not sure how long it will hold up for but sure was an easy fix. LOL

that's what I love about the tfs pumps. For the gpm they are cheap. And for me have been much more reliable than other pumps. 4350 psi? That could come in handy now and then. But for the most part I don't need or want more than 2,500 or so

I dont think I may need the 4350 either, but for those long runs of hose and just to see if some hard concrete surfaces look cleaner.

I have been trying to use more chemicals to do the work on the concrete lately. I used to turn my burned all the way up and go at if but after finding some good chems I keep the bruner around 160-180. I had been having to many hoses blow at high temp. Had one blow off at the gun and get me good in the crotch with hot water. Trust me that's scary.

The hoses that have blown were on the TSF's pumps? and were the hoses 3/8" 2 wire?
 
I had a hose blow while I was on a roof cleaning a fan , the hose busted right at the gun, came off of the crimped fitting and busted me in the head , 210 degree shower head to toe... then I slid down the roof and luckly caught a vent pipe on the way down.. Now I use all 5400 psi 2WB Hose..
 
Worst decision I ever did equipment wise was use the cheap imported hose when my goodyear neptune hoses started dieing after 4 years of use.
Every section I bought was dead , either the ends coming off the crimps or blowing out the side within 8 months. I went back to the goodyear hoses and have only replaced O rings since then.
 
I have had good luck with the Goodyear Neptune hoses also.

Just bought some different kinds from another supplier to give them a try, longer hoses for a larger hose reel, hopefully they will last.
 
I am hard on hoses. We do a lot of dealership work so they get dragged on the asphalt and snaged under tires.
 
yes they were on tsf pumps. 3/8'' 2 and 1 wire hoses. I usually use 1 because of the weight factor.

With high flow there is so much loss due to friction with 3/8" hose, and that friction adds more shear stress on the smaller size hoses they may burst more frequently, not to mention your energy losses. After i saw the friction loss chart on general pump website I made the decision to use 1/2" hose.

Great news! The cracked head (manifold) may be covered under warranty. You may send it to us in a USPS flat rate box or via UPS for evaluation. We are a certified General Pump Service Center. We will inspect it and inform you immediately if it is worth sending into GP for replacement. GP used to be a bit more liberal in covering the warranties. We have had pretty good luck in the past.
