Applications

The Ballast Puppy is designed to pump water into Wakeboard Liquid Ballast Tanks and when reversed will also pump water out of them. It has a flow rate of 11 gallons per minute, so it can fill most ballast tanks in about five minutes. It is equipped with a RunDry Protection Device to automatically shutoff the pump and protect the impeller from rundry damage should the pump be mistakenly left on after the Ballast Tank is empty. INSTALLATION The pump must be mounted in a dry location the motor is not waterproof and must not be submerged. Selection of a cool ventilated location will generally extend pump motor life.The unit can be mounted in any desired position. It is best to mount so that water dripping from loose port connection will not wet the motor. The pump head may be rotated 180 degrees on the motor to change the direction of flow. Pump ports have external 1 Inch hose barb and internal 1/2 Inch pipe threads. Use hose that does not kink when bent and with sufficient wall thickness to prevent collapse when used on suction side of pump. Hoses should be routed so that some water will be retained in pump body to wet the impeller. Wetting the impeller aids in priming and extends impeller life. Use a strainer on the intake hose to stop trash and solids from going through the pump. All hoses must have airtight connections to enable fast priming. OPERATION The Ballast Puppy is reversible so it can both add liquid ballast and then pump it back overboard when ready to lighten the load. The stylish double throw reversing switch is intended to be mounted in a convenient, easily accessible location for quick and easy ballast control. The pump can fill a typical forty gallon tank in about 5 6 minutes. The Ballast Puppy is designed for intermittent duty cycles only. When ready to add ballast, simply flip the switch to the fill position and watch for indicators that the tank is full, then switch the pump off. To reduce the ballast load, flip the switch to the drain position and the pump will reverse itself to pump liquid ballast back overboard. To fully empty tank, just leave the pump in the drain position and monitor the tank level so that the pump can be turned off when the tank is empty. Alternatively, simply pay attention to the sound made by the pump and when the frequency changes and it gets louder, that is an indication the tank is empty and the pump should be turned off. However, if for some reason attendants become distracted and do not notice the change in pump sound or that the tank is empty, the Jabsco Ballast Puppy is equipped with an exclusive RunDry Protection Device to prevent serious impeller damage. This RunDry Protection Device senses the absence of water and after a short period of sustained rundry operation will shutoff the pump before the impeller is badly damaged.The delay in rundry operation before pump shutdown provides adequate time for initial pump priming when filling the ballast tank. The Ballast Puppy is designed for intermittent duty cycles only. It is capable of filling most ballast tanks in about 5 6 minutes and can be immediately reversed to empty the tank if urgent deballasting is required. However, after about twenty minutes of continuous running the RunDry Protection Device will interrupt power to the pump and cause the pump to shutdown. The pump would then need to cool off for about twenty minutes before normal operation will resume.
