EVP company developed the two stage liquid ring vacuum pump DLV seires are adopted the stainless steel 304 material impeller. If the pumped meidum composition will not produce any corrosion for SS 304 material, and the water temperature is not too high to cavitation,then the service life will be ...

From the driving end, the rotation direction of the pump pulley is generally the rotation direction of the pump, usually it is clockwise. When the impeller rotates clockwise, the water entering the pump body is thrown around by the impeller. Due to centrifugal force, the water forms a closed wate...

Fruit freeze-drying and fruit cooling & preservation are different. Fruit freeze-drying requires a condenser (usually provided by the freeze dryer manufacturer) between the cavity and the pump to condense water and prevent water from entering the pump. Generally, 2XZ series double-stage oil-s...

If use water as working liquid in the application of oil refining, the pumped medium can easily react with the working fluid to form crystallization, resulting in damage to the mechanical seal and leakage of the working fluid. It is recommended to replace the working fluid with oil. This type of ...

Molecular vacuum pump is a high precision vacuum pump widely used in laboratories, such as some lab with strict requirements on the field environment, medical research and coating fields can see the wide use of molecular pump. Due to the different process, part of the process needs to do anti-cor...

What are the requirements for vacuum pressure stability in a milking system? The vacuum pump continuously extracts air from the milking system to create a vacuum environment, while the vacuum pressure regulator responds to the air demand in time to maintain the stability of the vacuum pressure in...

Whether it is EVP series or EVP-PB series scroll pump, the main purpose is to evacuate as vacuum pump, not to press as a compressor, better to keep their exhaust environment to be one atmospheric. When there must be pressure at the exhaust side, then maximum exhaust pressure that EVP-PB series sc...

Vacuum filter is a kind of equipment that realizes solid-liquid separation with vacuum negative pressure as the driving force. Under the action of vacuum negative pressure (0.04-0.07MPa), the liquid in the suspension is pumped away through the filter medium (filter cloth), while the solid particl...

Liquid ring vacuum pump as the most common one of the crude vacuum pump, with its stable performance in different industries have a very wide range of applications, common but not limited to the use of industries including power plants, paper mills, sugar mills, and so on…… Due to dif...

EVP liquid ring vacuum pumps are very popular in mines, such as the application of vacuum drum filters in copper, nickel, lead, zinc and other mines; here we share some of our customers in the Americas. The mines use CL3003 liquid Ring vacuum pump, we replaced the parts of the old NASH CL3003 pum...
