This heavy-duty portable vacuum pump is fully assembled and easy to use. All you need to do is plug it in! This pump has the capability to milk up to two buckets at a time for cows, goats, or sheep.
This Deluxe pump unit ships fully assembled by truck freight. Since there is no assembly required, it should be ready to plug into 110 volts upon arrival, and before each use. The oil level gauge is the small piece of clear hose in a U-shape on the side of the pump. Oil level should be close to the top of oil tank. To add oil, simply pop out the black plastic plug on top of oilisture trap and vacuum storage tank. Milk or water that gets drawn into the pump should drain out the duckbill drain in the bottom of the tank. If too much water or milk enters the tank, the pump will need to be flushed. See the maintenance section for instructions on flushing the vacuum pump.
How to control vacuum level:
The ideal vacuum level for milking cows is between 14 and 15 inches of vacuum. Goats are 12 inches of vacuum. To adjust level, loosen the nut on top of the regulator and turn the main body to adjust. Turn the body clockwise to increase and counter-clockwise to decrease vacuum level. Tighten the nut when the desired vacuum level is reached.
Refill oil tank with a good grade of high detergent motor oil or vacuum pump oil. Oil level should be 1/2 or 3/4 in sight tube. Add when oil level drops to 1/4 in sight tube.
