High-capacity rotary vane vacuum pumps and precision servo-regulators engineered for commercial dairy parlors.
From rapid retrofit upgrades to complete turnkey vacuum infrastructure.
Designed to support stable vacuum performance across commercial milking routines when sized for the complete installation.
Precision servo-regulators respond to changing air volume. They help manage vacuum changes when the regulator, reserve capacity and pipeline layout are correctly sized and maintained.
High volumetric efficiency from single units. Can be configured in synchronized dual-pump setups where the required airflow, pipeline layout, electrical supply and operating scope are confirmed.
Built with carbon/fiber vane and oil-lubrication configurations for commercial dairy duty. Confirm duty cycle, ambient conditions, installation and maintenance requirements for the selected model.
We engineer the vacuum generation, regulation and trap arrangement to help manage pump protection from pipeline moisture.
Stable Suction Generation
Oil-lubricated heavy-duty pumps operating at 1440 r/min. Includes high-capacity lubrication pot, belt guard, and industrial noise silencers.
Configurable Regulation Response
Response characteristics and operating range are selected around expected air admission, pipeline volume and pump capacity.
Moisture & Debris Defense
Galvanized vacuum reserve tanks and sanitary interceptors help protect the pump block from milk and wash-fluid carryover when installed and maintained with the selected system.
Match your parlor's milking points to our engineered pump series for a vacuum configuration reviewed against the project layout and applicable installation requirements.
* General sizing rule: (Number of Units x 120 L/min) + Reserve. Values vary based on CIP pipeline diameter.
A properly sized vacuum system helps manage vacuum stability and support a consistent milking routine.
Vacuum instability can affect the milking routine and should be assessed with the complete cluster, liner and pipeline arrangement. When pressure drops and abruptly surges, milk droplets containing bacteria are propelled backward into the open teat canal (impact cross-contamination).
By upgrading to an integrated NexAgri servo-regulator, the project target setting and regulation response can be reviewed against the selected equipment and operating conditions.
Undersized pumps experience severe pressure drops during peak milk flow or when a cluster accidentally falls off. This causes all other attached units on the line to slip, slowing down milk harvest.
Our heavy-duty pumps maintain an overwhelming airflow reserve, supporting the required reserve capacity for the project when the system is correctly sized and maintained.
High volumetric efficiency means you extract more airflow (L/min) per kilowatt of electricity consumed. Coupled with long-life fiber vanes and a high-capacity oil lubrication system, the physical wear on the pump block is minimized. Routine maintenance is reduced to simple oil top-ups and annual vane inspections.

Practical answers for dairy farms, equipment distributors and project teams selecting central vacuum equipment for milking installations.
Provide the number of milking units, parlor type, pipeline length and diameter, cleaning requirements, available electrical supply and any existing vacuum equipment. These inputs are used to review airflow demand, reserve requirements and the suitable vacuum-system configuration for the installation.
The page uses a general starting rule of the number of milking units multiplied by 120 L/min, plus reserve. The final capacity should also account for pipeline dimensions, cleaning load, altitude, parlor layout and the selected milking equipment. Use the configuration table as an initial guide, then confirm the final pump model against the project data.
Yes, a vacuum pump for milking machine replacement or retrofit can be assessed when the existing layout is documented. Share photos, pipe and connector sizes, pump-room space, electrical supply, current milking-unit count and any regulator or trap arrangement. This allows the pump, regulator, reserve tank and connection scope to be checked before quotation.
The vacuum-system scope shown on this page includes rotary vane vacuum pumps, servo regulators, vacuum reserve tanks and sanitary traps. The final equipment list depends on the required airflow, operating vacuum, pipeline arrangement and whether the project is a new installation or a retrofit.
For the oil-lubricated pump configuration shown, routine checks include the oil level, drive-belt condition and vane condition. The page refers to daily oil-sight-glass checks, monthly belt inspection and vane checks around 2,000–2,500 operating hours; follow the applicable model manual and the actual operating conditions when setting the maintenance schedule.
A dual-pump configuration may be considered where the project requires higher combined airflow, additional reserve or a larger parlor layout. On this page, the Dual HL-V-2100 configuration is shown for 40+ milking units with 4,200 L/min combined airflow. Confirm the required arrangement from the complete system calculation rather than unit count alone.
Vacuum reserve tanks help manage system reserve, while sanitary traps are used to intercept moisture and liquids before they reach the pump block. Their sizing, placement and inspection requirements should be reviewed with the pipeline layout and cleaning procedure so the protection arrangement matches the installed milking system.
