Product Description

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.

 Product Function

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.

Connection Method

Connect the device to be decompressed with the air inlet of the diaphragm pump through a hose; connect the inlet and outlet of the circulating liquid of the refrigeration equipment to the outlet and inlet of the condenser respectively.

Product Features

It can replace circulating water vacuum pump and rotary vane vacuum pump.

No working medium is required, and the working part has no friction.

It is easy to control the degree of vacuum and is stable; it can be adjusted according to the needs of the experiment.

Parts in contact with gas are treated with Teflon (PTFE) surface, which is resistant to chemical corrosion.

The valve plate adopts imported material.

The motor comes from the manufacturer ODM; reasonable transmission design; self-cooling and exhaust system; long-term continuous operation.

Small size, light weight, easy to move and save space.

Easy to repair and maintain.

The air inlet is a separation bottle, which prevents solid particles and liquid water from entering the pump.

The condenser at the air outlet performs secondary recovery of low-boiling point substances to improve the recovery efficiency and avoid the discharge of organic solvent waste gas into the atmosphere.

Product Application

Diaphragm pumps are mainly used for the recovery of alkane, aromatic hydrocarbons, ketones, ether, alcohols, nitrogen-containing compounds, sulfur-containing compounds and other reagents; suitable for petrochemical, pharmaceutical, paint, artificial leather, electronic products, painted gold ornaments, sports equipment, plastic products and precision manufacturing industries.

Precautions for Use

It must be placed in a dry, clean, level and well-ventilated place.

Liquid infiltration is strictly prohibited.

It cannot be used for decompression filtration of flammable and explosive liquids and gases.

The power cord should be tucked away when not in use; and the device should be stored in a dry place.

Repairs should be performed by professionals.
