When installing a Bell and Gossett Series 100 pump, you want to make sure that there is enough room around the pump for inspections and for service tech’s to get near the pump in case of any problems. Often these pumps are not given enough space and it costs more for a tech to come in and clear a path to the pump. Save yourself some money and make the pump accessible. Perhaps one of the most important things you have to do before installing a Series 100 pump is to make sure that your measurements and your sizing is correct. Not having a secure installation can affect the way your pump and accessories will work.

The Series 100 Bell and Gossett Pump can be installed with some versatility. The pump’s discharge can be installed up, down, to the right or to the left. But, most importantly that your oiling ports are facing up at all times. The bearing assembly and the motor should be kept at a horizontal position. You should read all manuals that come with the pump before you install it or have it installed. The part about oiling the pump before you install it is very important. You have to make a schedule of when you are going to check the oil, if there is no oil then the pump will seize and you may be too late to save it. This would mean spending money on a new pump. So make sure you set out an inspection schedule for yourself to make sure you are contributing to the smooth operation of your pump system.
