Packing pump

Packaging pump to meet your efficient and clean vacuum needs: large pumping speed range, clean and pollution-free, to meet the pharmaceutical and chemical industry and other harsh clean environment needs!

The principle of medical vacuum packaging machine is to use plastic composite film or plastic aluminum foil composite film as packaging material for vacuum packaging or vacuum aeration packaging. Vacuum packaging machine for medicine has the form of vacuum pumping which can keep the product for a long time. Because the vacuum packaging machine for medicine should be used in places with high requirements such as dust-free and aseptic workshop, it can also be used in food packaging with aseptic requirements to achieve good results.

Relevant experts pointed out that vacuum packaging machine is of great significance in the production of aseptic bags. The application of vacuum pump can pack and preserve the aseptic package, prolong the validity of the aseptic package, and the storage time can be up to 6 months. The storage time of aseptic bags with general packaging technology is only about one month. Vacuum packaging method is simple, easy to operate, less investment, no residual toxicity, safe and reliable, and suitable for vigorously promoting in the field of medical packaging.

The main products of pharmaceutical packaging company are small rubber components for medical equipment. It mainly produces rubber parts for syringe plungers and sealing caps for sterile products. The screw vacuum technology is used in the thermoforming machine. The vacuum system equipped with four screw vacuum pumps ensures excellent product quality, so that air and air bubbles in rubber parts are completely removed during the forming process. The rubber plug of the blood collection hose and the components of the disposable syringe, etc. The manufacturing process includes all stages of production from mixing raw materials to shipment of finished products of aseptic rubber components.


The first stage of production is to mix rubber with additives and chemicals to form ribbon substrates, and then roll them into rings. The composition of these substrates depends on their future applications and is prepared according to customer specifications. Two production lines consisting of 12 thermoforming machines automatically cut these strip substrates into appropriate sizes. The cut material fragments are pressed into the die under vacuum. Then different components are stamped, vulcanized, tested, washed and packed.

The forming process requires huge mechanical pressure, at which the temperature is between 175 C and 180 C, and the vacuum is 1 mbar. The above vacuum degree must be achieved in order to remove bubbles from the finished components and remove steam generated by high temperature and high pressure in the process. These machines were originally equipped with oil-lubricated rotary vane vacuum pumps, but soon serious problems arose: the vacuum pump oil reacted with the steam generated in the processing process, resulting in the formation of emulsions and oil deposits in the vacuum pump. These deposits reduce the performance of vacuum, so they can no longer achieve the required vacuum and pumping speed.

After thorough analysis by EVP vacuum experts, the solution is to replace oil lubricated rotary vane vacuum pump with packing pump-screw vacuum pump. Subsequently, the screw vacuum pump was tested in detail. This vacuum pump does not use working fluid in the compression chamber during operation, which means that the extracted steam will not contact with any other medium in the vacuum pump. In addition, the operating temperature of the vacuum pump prevents the steam from condensation when passing through the pump.

Packaging pump material:

Pump body: ductile iron, no coating

Rotor: Graphite cast iron, uncoated

Synchronized Gear: Alloy Steel, Fine Grinding, Helical Gear

Driving End Seal: Mechanical Seal-Lip Seal

Non-Driven End Seal: Triple-lip Seal-Double-lip Seal

Drive shaft end seal: mechanical seal

EVP professional vacuum pump manufacturers, the main products are packaging pumps, rotary vane vacuum pumps, screw vacuum pumps, Roots vacuum pumps, piston vacuum pumps, turbomolecular pumps, oil-free claw vacuum pumps, and provide vacuum application technology solutions.
