GM-0.33A Diaphragm Vacuum Pump, 20L/Min, Tianjin Jinteng Experimental Equipment Co.,Ltd. (CAT#: STEM-GLE-1380-YJL)

GM-0.33A Diaphragm Vacuum Pump, 20L/Min, model GM-0.33A, is manufactured by Tianjin Jinteng Experimental Equipment Co.,Ltd. This product is a dry-running vacuum pump with relatively low degree of vacuum. Its working principle is to stretch and compress the diaphragm reciprocatingly, causing the volume of the diaphragm chamber to change, and then switch the air path with a one-way valve to complete the vacuum extraction function. Diaphragm vacuum pump, with advanced design, high working efficiency and long service life, is a new generation product integrating high and new technology. Except for the applicable occasions of circulating water vacuum pump and rotary vane vacuum pump, it is also used in the fields of medical and pharmaceutical product analysis, fine chemicals, biochemical pharmaceuticals, food inspection, and criminal investigation technology. It has obtained a number of national patents, is safe, reliable, and easy to apply.

No need for any working medium (no oil) and no pollution. At the same time, the gas exchange chamber of the machine has built-in filter materials to ensure the purity of the air.
New technologies and new materials are used in the production process. It is easy to move and works smoothly, thus guaranteeing ideal vacuum and high air flow rate.
The special motor has passed the EU CE certification and is provided by the professional export motor manufacturer ODM. Reasonable rotating design, equipped with overheating power-off protector, automatically power off when the temperature of the pump body reaches 130 ℃, and protect the motor from damage under long-term operation.
It adopts frictionless membrane movement, which does not generate heat and has no friction loss. The diaphragm adopts imported rubber, which is corrosion-resistant and has a long service life.
The body is designed with an automatic cooling and exhaust system, which can ensure continuous operation for 24 hours.
The pressure adjustable design can meet the vacuum degree and gas flow rate within a certain range.
The bearing adopts imported classic bearing, which has stable operation, low noise and high work efficiency.
The parts of the anti-corrosion pump in contact with the gas are treated with Teflon surface, which has complete chemical corrosion resistance.
Small size, light weight, easy to move, save laboratory space, easy to repair and maintain.
