Thousands and thousands of these pumps have been sold to homebrewers.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eThe New Design\u003c\/b\u003e\u003cbr\u003eNow, with a slight design modification, the new model nearly eliminates past cavitation issues (where the impeller spins in an air pocket and no liquid moves). We've been testing\/using the pump with our BrewSculptures for several years now and are extremely happy with the results, so much so that we are completely replacing the H315 with the high flow model.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eStill Works the Same\u003c\/b\u003e\u003cbr\u003eThe new model comes with all the great features of the original - magnetic drive, handles flow restriction, okay for boiling temperatures, 6' cord with plug, food-grade materials in contact with the liquid, 1\/2\" ports, etc. - but now features a different slightly higher flow rate with less issues of cavitation.\u003cbr\u003e\u003cbr\u003eThe magnetic drive in a March pump acts as a clutch allowing the user to put back pressure on the pump to slow down flow. \u003cb\u003eSince it is magnetic drive, it is not self-priming, you must put the pump below the level of the liquid source. This pump cannot be run dry.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdditional Notes\u003c\/strong\u003e\u003cbr\u003eTo restrict flow place a ball valve on the out flow of this pump.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIncluded bracket for mounting\u003c\/li\u003e\n\u003cli\u003e6' power cord with plug wired in for easy use\u003c\/li\u003e\n\u003cli\u003e115V - 50\/60Hz\u003c\/li\u003e\n\u003cli\u003eMaximum flow of just over 7 gpm (at zero head)\u003c\/li\u003e\n\u003cli\u003eMaximum head of 18 feet (at zero flow)\u003c\/li\u003e\n\u003cli\u003e1\/2\" mpt fittings on both inlet and outlet.\u003c\/li\u003e\n\u003cli\u003eMaterials in contact with solution: Polysulfone, 316 stainless steel, silicone rubber, Ryton and Teflon\u003c\/li\u003e\n\u003cli\u003e1\/25 hp, continuous-duty, thermal overload protected, single phase 1.4 Amp motor\u003c\/li\u003e\n\u003cli\u003eMotor is fan cooled\u003c\/li\u003e\n\u003cli\u003eWill handle internal pressures to 50 psi.\u003c\/li\u003e\n\u003cli\u003eMax temp rating: 250F\u003c\/li\u003e\n\u003cli\u003eFace unscrews and rotates at 90 degree intervals to adjust to your application.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cu\u003e\u003cstrong\u003eNote\u003c\/strong\u003e\u003c\/u\u003e: When using silicone tubing, we recommending using a slighlty larger barb than the I.D. of the tubing.
