Vacuum pumps above 3.7kW are vacuum pumps with a capacity greater than 3.7kW. Unlike water pumps (water pump motors), vacuum pumps above 3.7kW are specialized equipment designed to create a vacuum environment by removing gas and liquid molecules from a sealed space.
With high capacity, this product line is capable of generating strong negative pressure and maintaining it for a long time. Vacuum pumps are commonly used in industries such as food processing, material manufacturing, electronics, medical, and many other fields.
Vacuum pumps above 3.7kW
Applications of vacuum pumps above 3.7kW
Large-capacity vacuum pumps are widely applied in various industries, including:
Food processing: In the food processing industry, vacuum pumps are used for vacuum packaging and extracting air from food products to extend shelf life and preserve flavor.
Material manufacturing: In material manufacturing, vacuum pumps are used to create a vacuum environment during the production of materials such as glass, ceramics, and composite materials.
Electronics: In the electronics industry, vacuum pumps are used to manufacture electronic components such as transistors, microchips, and other semiconductor devices.

Advantages of vacuum pumps above 3.7kW
Below are some advantages of vacuum pumps above 3.7kW that make this equipment an ideal choice for many production systems:
Strong suction, high stability: One of the prominent advantages of large-capacity vacuum pumps is the ability to generate powerful and stable suction force. This ensures that the production process runs continuously and efficiently, without interruption due to insufficient vacuum pressure.
Durable operation: The vacuum pumps provided by Thành Thái Motor are manufactured from high-quality materials, ensuring durable operation in harsh industrial environments. They can withstand heavy loads and operate continuously for long periods without trouble.
Suitable for heavy industrial environments: With a sturdy design and good resistance, large-capacity vacuum pumps are suitable for various industrial environments, including those with high humidity, dust, and extreme temperatures.
Long lifespan, easy maintenance: The vacuum pump product lines we supply have a long lifespan and are easy to maintain. Periodic maintenance helps the machine operate stably and extends its lifespan, minimizing repair and replacement costs.
Diverse capacities and designs: Thành Thái Motor provides a wide variety of vacuum pumps with different capacities and designs to meet all customer needs. From rotary vane pumps, liquid ring pumps to dry pumps, we have them all available to serve you.

Vacuum Pump Prices above 3.7kW at Thành Thái Motor
Below is the latest vacuum pump price list for 10/2026 updated by Thành Thái Motor, to help customers easily choose according to their needs.
Why does a vacuum pump above 3.7kW running continuously spray dense white oily smoke out of the exhaust port?
This is a sign that the oil separation filter inside the exhaust chamber is clogged, saturated, or torn. With a large-capacity motor above 3.7kW, the airflow pressure passing through is extremely strong; if the filter is damaged, it will push raw oil directly out. You need to check and replace the separation filter periodically after every 2000 – 3000 hours of operation.
How to wire a vacuum pump motor above 3.7kW (label Δ/Y 380V/660V) to achieve maximum negative pressure?
You must wire it in Delta (Δ) configuration when using a 3-phase 380V power supply in Vietnam for the motor to reach its rated capacity. If incorrectly wired in Star (Y), the motor will experience under-voltage, run extremely weak under load, leading to failure to drive the vanes deeply, causing vacuum pressure drop and overheating, burning out the windings.
How often should the composite vane set of this large pump series be replaced and what are the signs of wear?
The vanes endure very high friction force and temperature under large capacity, and their wear must be checked after every 5000 – 8000 hours of operation. Signs of worn or chipped vanes include: the machine makes a steady clicking sound in the pump chamber, and the pressure gauge cannot pull deeply down to the absolute negative pressure level as initially even though the oil and filter are still clean.
