The commonly used vacuum pump oil for SV rotary vane pump is 100# or 68# oil, but if the user’s local temperature is too low or it is used outdoors, it is recommended that the customer use anti-wear hydraulic oil, which can withstand low temperature, #46/ #68, and actually does not freeze a...

Our common Roots pumps now have the following models: ZJP-70 (70L/s), ZJ/ZJP-150 (150L/s), ZJ/ZJP-300 (300L/s), ZJ/ZJP-600 (600L/s) , ZJ/ZJP-1200 (1200L/s), ZJP-2500 (2500L/s) Among them, only ZJP-70 is air-cooled, and the others are water-cooled. The water-cooled main cooling is the skeleton oi...

Freeze drying can choose different pumps according to the size of the chamber, the required vacuum, food or industrial products. The following are our selection suggestions. When the chamber size of freeze dryer is small: 2XZ, EVP series scroll pump. When the chamber is relatively large: 2/2H sli...

Circled in the figure below is dry screw vacuum pump’s sewage outlet, which is used for purging waste liquid discharge: If the application is not for solvent recovery, then simply place a bucket under this port to collect the waste through the purification system. If the customer’s applicat...

The liquid ring compressor is a positive displacement compressor, which directly depends on changing the gas volume to increase the gas pressure. The characteristics of the liquid ring compressor are simple structure, easy manufacture, simple operation, few wearing parts, and small exhaust pulsat...

LG and LGB series dry screw vacuum pumps can manage both condensable vapors and some solids with no residue. They offer a number of advantages over the traditional vacuum pump designs. There’s is “NO OIL NO WATER” in contact with the process vapors, so therefore they are conside...

The model from 2BV2 060 to model 2BV2-071 monoblock type liquid ring vacuum pumps can not do double mechanical seal, even changed to 2BV6 series ( the model from 2BV6 060 to model 2BV6-071 liquid ring vacuum pumps ) which still is not available. For 2BV5 series liquid ring vacuum pumps also are n...
