How to build a simple goat milking machine

Updated November 21, 2016

Goat owners often build their own simple goat milking machine when they have too many goats to milk by hand and cannot afford a commercial milker. The milking machine is quite simple in design, but requires specialised parts. These parts can be sourced at dairy supply shops and often online at eBay. The machine operates by using a vacuum pump to form suction to draw milk from the goats teat into a milk bucket.

Cover the milk bucket with the lid. Make sure the gasket is placed under the lid. This ensures a vacuum seal can be created.

Place the pulsator on the lid over the check valve. Make sure the pulsator is the right size and fits the lid. A mismatch will not properly vacuum seal the machine.

Build the milk hoses. Milk hoses each consists of tubing with an inline shutoff value located directly behind an assembled teat cup. Assemble each teat cup by inserting a single inflation. The inflation is the machine part that goes around the goats teat. Attach the assembled teat cups to each hose on one end only. Cut each hose 5 cm (2 inches) back from the teat cup. Install an inline shutoff valve. The shut off valve is for cutting the vacuum pressure to individual teats as they are finished milking.

Attach the assembled milking hoses to the nipples on the lid to the milk bucket.

Attach the vacuum pump (includes balance tank and regulator) to the pulasator. The balance tank has a regulator that allows the user to adjust the vacuum level. The pulsator allows the controlled vacuum level to reach the ends of the milking hoses. This draws the milk from the goats teat into the bucket without sucking milk back into the balance tank.


Research and purchase all the specialised parts. Ask a reputable dairy supply company for advice when selecting the parts for a milking machine. They can help ensure all the proper parts fit together. Make sure the vacuum pump has a balance tank and regulator. These are critical for monitoring and adjusting the amount of suction during the milking process.


When parts don't fit together properly, the vacuum seal fails.
