Engineered for Stable Milking Performance

Discover why experienced commercial dairies rely on rotary vane vacuum technology for daily operations.

Stable Milking Phase

The rotary vane system provides a stable vacuum reserve with smooth airflow characteristics throughout the milking process. This helps maintain consistent teat cup attachment, reduces vacuum fluctuations, and supports a gentle, reliable milking rhythm.

Low Noise Operation

The precisely engineered rotary mechanism significantly dampens operational noise. Essential for keeping cows, heifers, or animals in the hospital barn calm.

Heavy Duty Chassis

Mounted on a reinforced, properly balanced tubular steel frame. Designed to withstand moisture and daily movement across uneven agricultural terrain.

Food Grade Materials

Equipped strictly with AISI 304 stainless steel buckets and food-grade silicone liners, ensuring easy CIP compliance and protecting milk quality.

Technical Excellence

Industrial grade components for continuous operational service.

Rotary Vane Vacuum Technology

How Rotary Vane Vacuum Technology Works: Rotary vane vacuum systems generate stable negative pressure through rotating carbon vanes, providing consistent airflow for dairy milking operations. Self-lubricating carbon vanes reduce friction and improve operating stability.

Mechanism: Oil-lubricated rotary vane pump for maximum longevity.
Air Capacity: 200-250 L/min air displacement. Readily compensates for air admitted during cluster attachment.
Motor Core: High-efficiency copper core motor (0.55kW - 0.75kW options), ensuring non-stop reliability.

Engineered by NexAgri Technical Team

A professional milking tool needs professional manufacturing and support.

Essential Spares Kit

Every wholesale machine includes a basic kit: spare liners, short pulse tubes, and seals to ensure continuous operation.

Voltage Compatibility

We customize the motor voltage and plug type based on your regional grid (110V/220V/380V, 50/60Hz).

Pre-Tested Quality

Every machine undergoes a continuous run test and vacuum calibration before leaving our ISO 9001 factory.

Total Cost of Ownership (TCO) & Value

Evaluate operational expenditures and ROI potential before finalizing your procurement decision.

1. Utility & Commercial Application

A mobile vacuum machine is an essential risk-management asset for larger operations. Commercial dairies deploy these units in sick bays to help isolate cows undergoing antibiotic treatment, preventing contaminated milk from entering the main bulk cooling tank.

2. Maintenance Lifecycle (OpEx)

The rotary vane system is highly durable but requires periodic monitoring of the vacuum pump oil level. With routine checks, the core pump mechanism operates reliably for years.

To maintain peak hygiene, the recurring OpEx involves replacing the rubber/silicone teat liners periodically according to usage cycles.

3. Animal Welfare & Yield Impact

Manual hand-milking is inconsistent, which can lead to stress and incomplete let-down. The vacuum pump system enforces a strict, biomimetic 60:40 pulsation ratio. This gentle massaging action ensures complete quarter evacuation, protecting the animal's long-term milk yield potential.

Financial Value Proposition

Labor Efficiency Improvement

ROI Depends on Scale

Transitioning away from manual milking dramatically reduces daily labor hours. The double-bucket configuration doubles throughput, generating significant time savings for growing herds.

Technical Frequently Asked Questions

Expert answers to help you configure and maintain your vacuum pump machine.

What is the difference between a mobile machine and a milking parlor?

A mobile machine is a highly portable unit designed for small herds, sick bays, or isolated cows. A milking parlor is a stationary, heavily automated installation meant for large commercial herds (50 to thousands of cows) focused on extremely high throughput.

How does a rotary vane vacuum pump improve milking stability?

The rotary vane mechanism ensures a continuous, non-pulsating extraction of air from the system. Unlike piston pumps that create micro-fluctuations with each stroke, a rotary vane pump maintains a constant vacuum reserve, ensuring the milking cluster stays securely attached and mimics a more natural, stable nursing rhythm.

Does the vacuum pump require oil maintenance?

Yes, our standard professional series utilizes an oil-lubricated rotary vane pump for maximum vacuum stability and longevity. This requires simple, routine checks of the vacuum oil level via the built-in sight glass. For completely oil-free environments, we recommend exploring our Piston Pump models.

How many cows can this machine milk per hour?

Actual throughput heavily depends on operator experience and cow preparation. Generally, the Single Bucket version milks 10-12 cows per hour, while the Double Bucket version can process 20-24 cows per hour.

How do I clean the system after milking?

Cleaning is straightforward. Place the teat cups into a bucket of warm, clean water and turn on the vacuum to flush the milk lines. Follow up with a standard dairy detergent wash and a final water rinse. The SS304 bucket and smooth lines are designed for easy CIP (Clean-In-Place) procedures.

Can I use this machine for Goats or Sheep?

Yes. While the pump and motor are identical, the milking cluster must be swapped for smaller goat/sheep silicone cups. We also recalibrate the pulsator frequency (typically faster than cows) before shipping. Please specify your animal type when ordering.

Can you customize the motor voltage for my country?

Absolutely. As the manufacturer, we equip units with motors compatible with your local electrical grid. We commonly provide 220V/50Hz, 110V/60Hz, or industrial 380V options.
