vacuum pump – the most suitable for you

The vacuum pumps of Henan Lanphan Industrial Co., Ltd. are of the following types: Circulating water vacuum pump (desktop, vertical), Rotary Vane Vacuum Pump, Diaphragm Pump (Solvent Recovery Vacuum System)

Circulating Water Vacuum Pump

The circulating water vacuum pump uses the rotation of the motor to drive the circulating water and extract the gas in the connecting system, which has achieved the purpose of gradually reducing the pressure in the system. At present, the circulating water pump is often used in the laboratory for decompression filtration and other operations.

Advantages:

  1. The water saving effect is obvious. Due to the water circulation operation, the water added to the water tank can be cycled back and forth, which overcomes the phenomenon of wasting a lot of water when the tap water method is directly vacuuming.
  2. Multifunctional comprehensive application. In addition to providing vacuum conditions, this machine can also automatically circulate water externally to provide circulating cooling water for the reaction device.
  3. Fashionable and easy to use.
  4. The machine is equipped with five suction nozzles, which can be used to pump air separately or observe the vacuum degree at the same time.
  5. Corrosion resistance, no pollution. The pump parts of this machine are made of stainless steel, and the water tank is made of ABS plastic. It is formed in one time and is not affected by corrosive substances such as acid and alkali.

Rotary Vane Vacuum Pump

Because the gas compression in the rotary vane vacuum pump is isothermal, it can extract flammable and explosive gas. Because there is no exhaust valve and friction surface, it can pump out dusty gas, condensable gas and gas-water mixture.

  1. Fast pumping speed, small size, light weight, low noise, convenient maintenance, and high ultimate vacuum.
  2. There is a reliable dust-proof device.
  3. Equipped with a bleed valve and a compound screw with an oil inlet hole.

Diaphragm Pump

  1. It can be used without working medium (no oil) without any pollution.
  2. The production adopts new technologies and new materials. Easy to move and work smoothly.
  3. Using frictionless operation, no heat is generated, no frictional exhaust. The diaphragm is made of nitrile rubber, which is corrosion-resistant and has a long service life.
  4. The fuselage is designed with a self-cooling air supply system. The system enables the machine to run continuously for 24 hours.
  5. The pressure can be adjusted through the valve to meet various vacuum requirements within a certain range.
  6. High-end axles have the characteristics of smooth operation, high operation efficiency and low noise.

Diaphragm Pump with Solvent Recovery Vacuum System

The diaphragm pump (solvent recovery vacuum system) provides vacuum conditions for evaporation, distillation, crystallization, drying, sublimation, filtration and decompression, and degassing; it is also used for solvent recovery, extraction of various highly toxic, flammable and explosive, strong acids and strong bases. In addition to being suitable for circulating water vacuum pump and rotary vane vacuum pump, it is also used in medical and pharmaceutical product analysis, public security criminal investigation technology and other fields.

The equipment can adjust the vacuum degree and pumping rate of the system, which is convenient for precise control and can realize the conventional distillation of closed system. When used in conjunction with a rotary evaporation system, it can achieve decompression and secondary recovery of low-boiling substances. Due to its high recovery rate, solvent off-gases into the atmosphere are avoided.
