Hey everyone, first time poster looking for some information on a fire pump that I found in my family's barn. The pump came out of a hospital that was being renovated and has sat in our barn for about 10 years. The serial number is 811-91170-1-2. It is attached to a 50 hp lincoln motor, serial number 2455426. There is also a control panel, serial number DE-817738 I. Model number on the control panel is M300-50-400B. I'm looking for any and all information on this set up, age and approximate value range in particular. The plan is to sell this unit so I really appreciate honest feedback. Thank you for looking and let me know if there is any more information I can give you that might be helpful. Pump, motor, and ten years worth of dust. http://imageshack.us/photo/my-images/560/3386354a7774485fb3e96e2.jpg/" rel="nofollow">  Pump info http://imageshack.us/photo/my-images/221/f83bd6f62bee4dd7acc5b46.jpg/" rel="nofollow">  Motor info http://imageshack.us/photo/my-images/337/bdfca63bdce147e887c5ac5.jpg/" rel="nofollow">  Control panel info http://imageshack.us/photo/my-images/684/e2a6cac7ce28409ab49ca52.jpg/" rel="nofollow">  |

It is a booster pump which requires a pressure supply to it , for other uses ? most fire systems need certification . What shape the packing glands and shaft wear sleeves are in or how good the impeller is ? As far as motors they are hard to sell , used even brand new bring little , when liquidating the motors from place i worked a motor like that brand new still on packing skid I got $30 for . ------------- Faith isn't a jump in the dark.

I provided engineering services for a fire pump installation. It was a diesel driven AC fire pump. It doesn't specifically say Allis Chalmers anywhere on the literature but the AC logo looks like an Allis logo. Sorry to say that the engine is a John Deere. ------------- Jack of all trades, master of none |

| Being a centrifigal these pumps can be utilized for many functions. So long as the water source(tank) is above it or it has a positive suction pressure it can deliver massive amounts or be throttled back to a reasonable minimum.We have similar pumps at work, minimum flow requirements are around 250/400gpm to keep the pump cool but can be run dead headed for short periods to start/stop them. |

As DMiller said these pumps can be used for other uses but they need a flooded suction or some positive suction pressure. I see the tag says 1000 gpm at 65 psi so that gives you an idea of capacity and might work well as an irrigation pump if it can be set up with positive suction pressure. Fire pumps see very little usage so it should be in good shape. Typically the fire code requires them to do a test run for 30 minutes once every week so they have about 25 hours run time every year. The controller might even be usable but not in a fire pump application as it probably doesn't comply with current codes for fire pump use. ------------- Jack of all trades, master of none |
