This newly designed March Pump comes with all the great features of the original March pump - a magnetic drive, handles flow restriction, boiling temperatures capability, 6' cord with plug, food-grade materials in contact with the liquid, 1/2" ports, etc. Now, with a slight design modification, this pump nearly eliminates past cavitation issues (where the impeller spins in an air pocket and no liquid moves) and provides a slightly higher flow rate. The magnetic drive in a March pump 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 below the level of the liquid source. This pump cannot be run dry.
Please note: When using silicone tubing, it is recommended to use a slightly larger barb than the I.D. of the tubing. This is because silicone tubing tends to have greater pliability than most tubing. For example, when using 1/2" silicone tubing, a 5/8" barb helps ensure a better seal.
