Dairy Vacuum Pump Control System

If you are milking 400+ holsteins in a double 12 parlor with two 10HP vacuum pumps, you would benefit from our new design by saving up to 40% of your vacuum energy costs.

Our energy saving variable speed control for your vacuum pumps and transfer pumps will reduce your maintenance costs and extend the life of the equipment.

If your original system utilizes two 10HP blower type vacuum pumps, the second vacuum pump will typically operate between 1/4 to 1/3 speed for most of the milking hours.

Your milking system electrical consumption may be reduced by up to 49,000kWh per year, which represents a reduction of 25% of the electric bill to run these motors. You will receive a payback of about two years based on energy savings alone.
