March 7S 1hp Brewery Water and Beer Pump

These pumps are magnetic drive units (not shaft/direct drive like cheaper pumps) 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 even for a short period of time the impeller and shaft may become overheated and damaged. A larger diameter hose should be used on the pump supply/inlet side than on the outflow side and the inflow should never be restricted in any way. To regulate the outflow (to control the rate of fluid movement) use a valve on the discharge/outlet (our Diaphragm Valve is excellent for controlling flow) only.

The TE-7S-MD has a maximum flow rate of 53gpm/200Lpm or head of 57ft/17m (maximum pressure of 25psi but with back pressure and 1/2" hose approx 4gpm at 18psi). The TE-7S-MD can be wired for either 120 or 240V power. The pump comes with two welded 1.5" TC connectors.

Additional products can be added such as hoses (8' plus 3' of 0.5"ID and 3' of 1"ID braided silicone hose), two 1.5" TC sanitary clamps, two 1.5" TC silicone gaskets (7S comes with welded TC connectors) and a pump cart.  

Note: Power cord, hoses and cart are NOT included with the 'pump only' option.

Note: When included, some assembly of the cart and power cord are required. Qualified personnel or electrician should be employed to connect the power cord to the pump and an appropriate plug (or hard-wired). If not connecting the pump to a BREWHA Power Controller Box (L6-15 cord ends are supplied with each BREWHA box and the pump should be wired according to the 'high voltage' pattern on the pump; do not connect this 1hp to a BREWHA BHPBWT single heater controller as total draw will exceed rating of the controller. If hard-wiring or connecting to your own supply, ensure proper load rating on a supply side fuse; refer to specifications sheet below.

Note: these pumps should NOT be ran dry at any time. Always have water unrestricted and free flowing into the pump using a 1" or larger diameter hose. Flow should only be restricted on the outflow side.
