Vacuum pumps under 50m3/h are designed to create a vacuum environment by removing air and other gases from a closed space. Their pumping speed, meaning the volume of gas the machine can evacuate per hour, is under 50 cubic meters (m3/h). This makes them suitable for small and medium applications where excessively large suction capacity is not required.
Vacuum pumps operate on the principle of creating a pressure differential between the inside and outside of the space to be evacuated. When the pump operates, it creates a low-pressure zone inside, causing air and other gases to be drawn in to equalize the pressure. This process continues until the desired vacuum level is reached.

Why does the vacuum pump under 50m3/h quickly become hot on the casing and the internal oil turn turbid after running for a while?
Because the pump continuously inhales high-humidity air or water vapor from the environment (especially in the fresh food packaging industry). Water vapor is compressed, condenses, and mixes into the vacuum oil, causing emulsification (the oil turns milk-turbid). Loss of oil viscosity increases mechanical friction, causing the pump casing to heat up quickly. Customers need to drain excess water at the bottom of the oil chamber or replace it with new oil immediately.
Can small vacuum pumps use a 1-phase 220V household power supply, or is 3-phase power mandatory?
In the segment under 50m3/h, manufacturers offer both 1-phase 220V and 3-phase 380V options. If used for small workshops or business households without industrial power, customers can completely choose the very convenient 1-phase 220V line, and the machine still achieves a deep negative vacuum pressure equivalent to the 3-phase line.
Why does the vacuum oil get sucked backward from the pump into the suction pipe and product chamber when the machine is turned off?
This error is caused by a damaged, dirty anti-suck-back check valve at the pump’s suction port, or the blocking spring losing its elasticity. When the machine is shut down abruptly, the negative pressure inside the suction pipe draws oil backward from the pump chamber. Customers need to disassemble the suction neck assembly to clean the valve dust or replace the rubber pad/spring of this check valve.
