March High Temperature Pump for Brewing Home Brew
This is the ideal brewing pump built by March Manufacturing. This pump is constructed of food-grade material, handles wort at boiling temperature, and takes back pressure (flow restriction). The pump housing is made from polysulfone because it is a tough, food-grade plastic rated to temperatures as hot as 250F, well above boiling wort temperatures.  It offers many of the benefits of the ideal material, stainless steel, without the prohibitive cost.The magnetic drive acts as a clutch allowing the user to put back pressure on the pump to slow down flow. Since it is magnetic drive, it is not self-priming, you must put the pump under the level of the liquid source.The pump is brewer friendly and includes a bracket so that it can be mounted and a 6' power cord with plug wired in for easy use. This is a tough little pump with a 1/25 hp, continuous-duty 1.4 Amp motor which can be run non-stop for extended periods. This pump has a maximum flow of 7.2 gpm with a maximum head of 12 feet. For an example of typical usage: with a head of 6' it will pump 3.25 gpm and with an 8' head it will pump 2.5 gpm. 1/2" mpt fittings on the outlet and 3/4" mpt inlet. Materials in contact with solution are Polysulfone, 316 stainless steel, silicon rubber, Raton and Teflon. Shaded pole, thermal overload protected, single phase motor is fan cooled. Will handle internal pressures to 150 psi. Max pressure the pump can produce in a closed system is a little over 5 psi. Face unscrews and rotates at 90 degree intervals to adjust to your application. To restrict flow place a ball valve on the out flow of this pump.  The center inlet port allows for easy draining and cleaning of the pump.  Side inlets cost slightly less, but will allow wort and water to sit in the bottom of the pump and mold overtime.  The center inlet makes it easy to clean and use.  This is why you see the center inlet port pumps in use at all professional breweries.
