Does as it should

My vacuum chamber and pump is truly amazing and does what i need perfectly except for one single fault - it smokes too much. Cant figure out why as i first thought it would be the first use but it wasnt.

Works well and to specifications. It is the most economical vacuum pump with great quality manufacturing. It can be used for multiple purposes, not just automotive refrigeration if you put a particle trap between the pump and object you are evacuating..

really liked,great products for great price !!!

This vacuum pump is amazing. Its 75% les cost then a comparable unit. Multistage and very powerful. Pulls down immediately. Can't beat the cost and built very well. Highly recommend

We have recently bought 2 model 2RS-4 vacuum pumps, the same after working 20 minutes or less they overheat and turn off, we understand this as protection, the question is normal that they cannot reach even 30 minutes.What could be happening with these pumps, can they tell us if this is normal or not?Our technician check the pump and reported that the screw (check picture) was almost falling and oil was licking from both pumps. Is that normal?

Purchased to use during install of a DIY mini split air conditioning system. The pump was a wonderful purchase. Used to drain 2 sets of lines, worked perfect, was extremely quiet, fast, smooth and very little vibration when compared to other single stage pumps. I was skeptical as not knowing the brands reliability but after using it, I would recommend it. The instructions included were well written and understandable. The pump did come with required oil in the box. Packaging was good.

Bought this vac pump to wet form leather products, holsters, knife sheaths, and phone holders. Great little pump. Powerful enough for the job

Great suction, worked great for the job, needs better instructions though, but I figured it out..
