Electric Sap Releasers (Extractors)

BHR Releasers are the maple sugaring industry's most reliable sap extractor. The electric releaser is kept under constant vacuum. It is drained with a water pump (appropriately sized, see below) that is connected to the releaser and discharged into a maple sap storage tank. Be sure the releaser is sized appropriately for the number of taps on the releaser. If the releaser is too small, the water pump will have to start-up more often and, during a high sap flow, overflow may occur.

Since this unit is constantly under vacuum, your water pump may lose efficiency. To correct this problem, your water pump should be slightly oversized.
