QUALITY FLOW SYSTEMS, INC. <br />800 6tn Street NW Phone (952)758-9445 <br />New Prague, MN 56071 Fax (952)758-9661 <br />9/17/2025 <br />Jimmy and Dave; <br />Here is a summary of what we talked about doing this year in response to the meeting <br />yesterday. Items in RED will be done <br />LS# 1: Both pumps have worn volutes and some wear to the rotating wear ring. Pump no. 1 has <br />a worn stationary wear ring. Pump no. 2 has some wear on the stationary wear ring. Pump no. 1 <br />volute and wear ring ready to be replaced. Pump no.l has a decent size leak in piping above the <br />base elbow. This could be repaired live on a low flow time of day. Disconnect leaky flange and <br />top 90, clean and replace both. <br />Recommendation: <br />A. Replace stationary wear ring in both pumps - $1,600.00 <br />B. Replace volute on Pump 1 - $4,300.00 <br />C. Repair piping leak - ?, possible remodel - ? <br />We need to have Cory look at this one when we come out to look at the two remodels. Once we <br />look at it I will quote this and add. <br />LS# 2: Pump no. 1 has a very worn volute, shot rotating wear ring, and shot stationary wear <br />ring. Pump no. 1 entire liquid end is worn including suction cover. <br />Recommendation: Replace Pump 1 - $12,640.00 (Note: Did pump 2 last year) <br />LS# 5: Both pumps had cloudy oil; changed. Both pumps also rattle when running. Both pumps <br />have a rattle running dry and both had cloudy oil. <br />Recommendation: Rebuild both pumps — Seals, bearings, o-ring kit - $12,860.00 <br />We need to visit the ACTUAL design condition for this station (original plans). Once we <br />have that we can determine how to proceed. This appears to be the wrong pumps for <br />the station! <br />LS# 7: Pump no. 2 consistently has around 25% longer runtimes - everything in the pump looks <br />fine. Confirmed same size impeller. Pumps are consecutive serial numbers so they should be <br />identical. According to 1500ct it has had 21% higher runtimes over its lifetime. <br />Recommendation: Okay! <br />Vince will look at the 1500 ct setup and see if we have an error in the setup. Scheduled <br />to come out on all these issues on 1013 @ 9AM <br />LS# 9: City says float mode activated keeps calling them. Found power seems to fold when both <br />pumps kick in. seems to be anytime a pump is running and the second pump starts both pumps <br />65 <br />
