All stainless steel vacuum pump

All stainless steel vacuum pump is a vertical all stainless steel vacuum pump which is made of 304 / 316 / 316L stainless steel by reverse casting. It adopts swirl down suction structure and unique over-current design, with full lift (no overload) and wide efficient area, complete drainage. It is suitable for the transportation of industrial and mining enterprises, construction sites, aquaculture, pharmaceutical solutions, drinks, sea water and places with a diameter of no more than 25 mm contained in general corrosive media with physical properties similar to water. After equipped with float switch, it can realize automatic control start and stop with the change of liquid level. The motor is equipped with a protector, which can cut off the power automatically in case of overheating or over-current, so as to ensure the safety and reliability of the pump running in the worse environment.

All stainless steel vacuum pump consists of water pump, seal and motor. The electric pump is equipped with a protection device, and the motor is located on the upper part of the electric pump, which is divided into single-phase and three-phase asynchronous motors. The water pump is located at the lower part of the motor, which is of centrifugal impeller and volute structure. The double face mechanical seal is used between the water pump and the motor, and the “0” shaped oil-resistant rubber seal ring is used as the static seal at each fixed stop seal.

All stainless steel vacuum pump is a kind of device or equipment that uses mechanical, physical, chemical or physicochemical methods to extract air from the container to obtain vacuum. Generally speaking, vacuum pump is a device which can improve, produce and maintain vacuum in a closed space by various methods.


1、 How does the oil vapor discharged from the vacuum pump affect the environment? If the environment is not allowed to be polluted, you can choose an oil-free vacuum pump such as water ring vacuum pump, or discharge the oil vapor outdoors.

2、 The requirements of vacuum equipment or spare parts for oil pollution. If the equipment is strictly required to be oil-free, all kinds of oil pumps should be selected, such as water ring vacuum pump, molecular sieve adsorption pump, sputtering ion pump, low temperature pump, etc. if the requirements are not strict, oil pumps can be selected, and some anti oil pollution measures, such as cold trap, baffle, oil trap, etc., can also meet the requirements of clean vacuum Ask.

3、 Whether the vibration produced during the operation of the vacuum pump has any impact on the process and environment. If the environment does not allow, the pump without vibration shall be selected or vibration reduction measures shall be taken.

4、 First of all, we should fully understand the composition of the extracted gas. If the gas contains no condensable vapor, particle dust, corrosivity and explosiveness, etc.; if the gas contains vapor, particle and corrosive gas, auxiliary equipment, such as condenser and dust remover, should be installed on the air inlet pipe of the pump; if the extracted gas has corrosivity, material should be selected; if the extracted gas has explosiveness, true should be selected Air pump and equipped with explosion-proof motor, because the whole working process of vacuum pump is isothermal.

5、 If there are several large vacuum pumps working at the same time, the circulating liquid should be cooled, otherwise the vacuum degree will be affected. The cooling device can be equipped with a cooling tower, and a booster pump must be equipped to pressurize the pipeline.
