Prices for vacuum pumps under 3.7kW at Thanh Thai Motor
To help customers easily purchase water pumps that suit their usage needs and budget, below is the latest price list for vacuum pumps compiled and updated by Thanh Thai Motor in 10/2026.
Why does the oil turn milky white and the pump casing become extremely hot after running for a short time?
Due to the pump drawing in high-humidity air or water vapor. Condensed water mixes into the oil, causing emulsification. The oil loses its viscosity, causing the machine to heat up and lose negative pressure. You need to drain the water from the bottom or replace it with new vacuum oil immediately.
Why is vacuum oil sucked backward into the pipeline and product chamber when the power is turned off?
Because the anti-suck-back check valve at the pump inlet is jammed with dirt, has a torn rubber sheet, or a broken spring. When the machine is suddenly turned off, the negative pressure in the pipe will pull the oil backward. You need to remove the inlet to clean it or replace it with a new valve.
Is it better to choose a 1-phase 220V or 3-phase 380V power supply for this pump line under 3.7kW?
In this segment, the machine is available in both types. If running continuously in an industrial workshop, you should choose the 3-phase 380V line for a cooler, more powerful, and stable motor operation. If used for small business households without industrial power supply, choosing the 1-phase 220V line still ensures equivalent vacuum depth.
