Chromed brass pump can be used for administration of large volume oral remedies, or for other volume-pumping requirements. A continuous flow is achieved as the device pumps on both upward and downward strokes. The castellated foot device prevents suctioning to container bottom, and also has a nipple suitable for connection of a 10mm suction tube. The outlet nipple will fit tubing from 10-15mm. Pump is 40cm high o.a. (closed) and delivers 120ml per stroke (up and down each). Note: Care must be taken with volume drenching or flushing of livestock. Use only under the instruction and supervision of a veterinarian.
