With a semi-open impeller that is accurately balanced, this Berkeley self-priming pump is up to the task. Ideal for use as a transfer pump for filling vats, tanks and spraying rigs, stand-by fire protection for marinas, vacation and residential properties, irrigation pumps for lawns and gardens, farms, draining excavations, ditches and flooded basements and any other application where a heavy duty self-priming pump is needed. This Berkeley motor-drive centrifugal pump is also an ideal pump, due to the cast iron construction for use with emulsion base pesticides and weed killers.
