Okay, I'll look into it and see what can be gotten cheaply. Thanks for the tip, Tom. Joe

Hi 256bits, Thanks for the continued help. The pump is an over the counter option, so to speak, given the scope of the project. So, I matched curve as best as possible with my requirements and plumbing conditions, knowing that throttling may be necessary for general use. Yes, the 44 %...

Hi 256bits, Thanks for the reply and for the heads up. Yes, you're right, I was providing the rated capacity, it seems, for the motor, not the generated heat in wattage. Sorry for the confusion. So, I checked the pump spec. sheet further. The nominal power is 370 W and the absorbed/input power...

Hi Tom, Thanks for your continued input, I appreciate it very much. I guess my hope in positioning the 3 inch intake pipe in vicinity of the pump's fan was that, although not ducted to the outside directly, the fan would have immediate access to cooler air, especially if pre-conditioned. I...

Hello Tom, Thanks for the reply and the link to the calculator. Regarding the motor's fan, sorry if I wasn't clear about this, but the pump and motor is a single fan cooled unit rated at 370 watts, with the fan at the rear providing the only cooling and so otherwise sealed. When you say an...

Hi everyone, I am thinking that I should probably further analyze my airflow/air exchange requirements for the underground vault, and perhaps I am getting ahead of myself in trying to manipulate the piping location and design first. In this regard, there may be some more concrete information I...

Hi Nik_2213, Thanks for the reply. I actually did not consider a coaxial flue. It's an interesting idea to minimize wall penetrations. Would this be less effective than an air supply directly at the pump's fan, though? Or perhaps that is just a simple way of looking at it, and an air supply is...

Hi 256bits, Thanks for the reply, and Happy New Year! The enclosure's main function is visual concealment, as well as protection against general access to the equipment/electrical and general weather conditions. The fountain will be winterized, and the pump most likely will be removed and...

Hello, I am currently designing and building a small utility vault to house a centrifugal pump for a water fountain, and I am specifically concerned with providing adequate ventilation not only during operation but also in general to reduce moisture and corrosion of the equipment. While all of...

Hello everyone, I just joined the forum, after a bit of lurking on some various threads. It seems like a great forum. While I'm not a engineer, I am involved in various areas of construction, and I always try to back up my designs and work with as much science and engineering as I can. I hope...
