Pumps, Wells, Tanks, Controls / Compromised motor saver?
« on: July 31, 2018, 10:44:59 AM »
I am working at a school in Maine and we have a SymCom Motor Saver model 520C (P/N 25A-135-UOO) https://files.clrwtr.com/userfiles/ct/documents/littelfuse/symcom-520cp-current-monitors.pdf that will not run. We have checked the power source, that appears to be in working order it's just that the reset button only activates the unit briefly and shuts off. It does this 3 or 4 times a push. A storm blew through here a couple of nights ago perhaps compromising the unit. The vendor is saying that SymCom 520C model is obsolete & to use LSR Series instead. https://files.clrwtr.com/userfiles/ct/documents/littelfuse/symcom-lsr-24-load-sensors.pdf I'm trying to validate vendor's recommendation here. If you have any other product suggestions, please guide me in that direction.

Pumps, Wells, Tanks, Controls / Issues with new pump panel
« on: May 22, 2017, 09:18:44 AM »
I recently had an electrician put together a “pump panel” for a 7 1/2 hp centrifugal pump – a Cornell 1.5 WH, 3600 rpm, single phase motor.  Within the pump panel,  he added on a “Pump Saver Plus, Model 235P”.  http://www.clrwtr.com/PDF/SymCom/SymCom-235-Pump-Savers.pdf This is a “flood suction” intake application – approximately 8 pounds pressure coming in – and ample volume – 6” pip poly line, approximately 1000 ft. long from a settling pond, with numerous constant working air vents.  It also has a “Barksdale” low pressure switch – Model# E1H-R90-SO0159 – incorporated into the panel – which is adjusted to it’s minimum at 3 lbs. pressure”.  I have used these in the past on other pump applications, yet not with a “Pump Saver”, and they worked great.
    I tried personally to fire up the pump, yet upon starting the pump, it immediately shut down and could not get it to stay running after opening up the discharge valves.  The electrician came back at my request, and stated “well, I never have wired one of these in, so this is the first time, and I don’t know why my boss added this on – the Pump Saver Plus”.  He also stated “he had never seen a “Barksdale low pressure switch”.
    Every time we tried firing the pump up, where we closed the discharge completely down – or dead headed it -  to start the pump, which it did start, although immediately upon opening the discharge valve, ever so slightly, the Pump Saver Plus kicked in and shut off the pump.  He made numerous attempts and adjustments to the “calibration” and “sensitivity” knobs, yet finally, after 3 hours,  gave up and disconnected the Pump Saver Plus, which then allowed the pump to operate flawlessly, pressuring up the system.   He left stating “well it runs, yet it won’t work with the Pump Saver”. 
    My questions is: Is there anyone that can help me diagnose the issue here in Wyoming?  The electrician charged me over $225 for installing this unit and it can’t be utilized.

Industrial / Pump saver submersible pump switch
« on: February 27, 2017, 12:56:00 PM »
I have a small dairy operation. My Pump Saver mod.# 231, 230 volt is over 20 years old and just started switching off when trying to reestablish pressure.

http://www.clrwtr.com/PDF/SymCom/SymCom-112-Insider-232-Pump-Savers.pdf

Will now only build 2-3 lbs. then switches off, so I have to keep throwing the fused breaker box switch off/on in order to build pressure.

Do I need a new switch?

Also, if the well makes just enough water to keep the amps from dropping too far, but not enough water to keep the pump cool, can I still have problems?

Hi Cary, Thank you for the fast response.

If the pump run dry, would it melt down or can create enough heat to melt off the drop pipe?

Also is there a big difference in amp draw between running the pump dry and just restricting it to 1 GPM?

Do pumps come with an internal run dry sensor?

I have a new 3/4hp Schaefer submersible pump down my well. The electrician recommended a Pump Saver Plus 231-INSIDER-P. The pump saver is manufactured by SymCom.

http://www.clrwtr.com/PDF/SymCom/SymCom-231-INSIDER-P-Pump-Savers.pdf

Is there a true cost benefit to installing a Pump Saver? Doesn't the pump already have some safety features already built in?

Thank you in advance for any help.
