This is a high-flow version of the classic March 809 pump for transferring hot and cool liquids during brewing. It has a max flow of 7 gallons per minute and a max head of 18.6 feet.
This pump is NOT self-priming, the pump head must be filled with liquid before it will pump properly. This means that you will have to position the pump below the level of the liquid for the input before turning on the pump. Do not restrict flow into the pump, only on the output side.
Magnetic drive of the impeller allows you to restrict the flow out of the pump, without affecting the motor.
We recommend some high-temperature 1/2" tubing in either Thermoplastic or Silicone for all connections to the pump and equipment.
Adding a 1/2" ball-valve to the output of the pump allows you to precisely control the flow of liquid from vessel to vessel or through a plate chiller. You can even stop the flow entirely using the valve, without turning off the pump and losing the prime!
A set of Quick Disconnects on your equipment and tubing make the brew day even easier.
