March 815 1/25hp Water and Beer Pump

March builds high quality pumps that will provide years of dependable service. Unlike cheaper pumps that can be frustrating to operate (due to such reasons as poor motor and body alignment leading to binding, poorly cast and low quality parts being easily broken, under powered motors leading to stoppage when grain enters the pump head and motors that readily burn out) these pumps are brewery workhorses that will provide years of dependable service. 

These pumps are magnetic drive units built specifically to handle hot wort and water. The benefits of a magnetic drive pump are that they are more reliable and require less maintenance, saving you money. Since they use a magnet to turn the impeller, the impeller is fully enclosed; there is no mechanical seal (where the drive shaft enters the head, connecting the impeller to the motor) which is leak prone and can be expensive to repair, and they are not positive displacement, which can over-pressurize leading to damage or rupture. However, they cannot handle high levels of solids (don't let a lot of grain into the pump hose) and do require liquid being pumped to lubricate and cool the impeller. If the pump is ran dry for even a short period of time the impeller and shaft may become overheated and damaged. To regulate the flow use a valve (ball, butterfly or diaphragm) on the discharge/outlet and always allow full, unrestricted flow into the pump.

The 815-SS-C homebrewery pump has a maximum flow rate of 8gpm/30lpm or head of 13.5ft/4.1m (approx 4gal/min at 5psi) and is a great size for Small, Medium and Large (20-60L/5-15 gallon) brewing systems. Pump comes with one 1/2" MPT outlet and one 3/4" MPT inlet post, stainless steel impeller enclosure and 5-15 plug (North America). Click here to see a larger, more powerful brewery pump.

Additional accessories can be added such as hoses (5' of 0.5"ID and 2' of 0.75"ID food-grade, high-temp, heavy-duty, high-pressure, braided silicone tube, two 1.5" TC (tri-clamp) clamps, two 1.5" TC silicone gaskets, one 3/4" FPT x 1.5"TC  fitting and one 1/2 FPT x 1.5" TC fitting) or hoses and pump cart. 

Note: do NOT operate these pumps dry. Water should always be unrestricted and free flowing into the pump through a 3/4" or greater diameter hose.
