DOVMXtech series diaphragm pumps feature integral forced-air cooling. They have two-stage PTFE diaphragms that are ideal for pumping corrosive gases and organic solvents. These pumps are oil-free, portable, and chemical-resistant, which means less maintenance and no more frequent and costly oil change, or cross contamination.
The diaphragm vacuum pump is a dry operated vacuum pump, a cutting edge product in the current development of vacuum pumps, and is becoming more widely used nationally. It can be used in vacuum dry suction and filtration, vacuum concentration, and can be used in a supporting rotary evaporator. And dry operation, which ensures no pollution pollution and is green and environmentally friendly. The contact gas sites are specially treated to have strong resistance to chemical corrosion. Durable for continuous operation.
Diaphragm Vacuum Pump provides negative pressure condition for processes of evaporation, distillation, crystallization, drying, sublimation, reduced pressure filtration etc. It can be used to extract a variety of highly toxic, flammable and explosive, strong acid and alkali sample.

usage method:
1. Switch on the power supply. Initiates the power switch. With the pump in smooth operation, the operation is started by connecting the native intake port with the pressure reducing device in place with a rubber hose. If a positive gas compressor flow is used, it can be used for work by connecting one end of the rubber hose directly to the exhaust port of the unit, producing a steady airflow.
2. When stopping the native, disconnect the pump from the unit to which the pressure reduction is required and switch off the vacuum pump's power switch.
