Oil-Free Diaphragm vacuum pump corrosion resistant protection


The oil-free diaphragm vacuum pump is a dry-running vacuum pump, which solves the problem of chemical resistance of the vacuum pump. It is especially suitable for applications where chemical resistance is required or long periods of uninterrupted operation are required. All parts in contact with gas are treated with Teflon (polytetrafluoroethylene PTFE) and reinforced with carbon fiber, which fully guarantees the chemical resistance of the pump. The diaphragm adopts a sandwich structure (ie, a multi-layer structure) to increase the toughness and strength of the diaphragm. Diaphragm vacuum pump JR-201T is an upgraded product of current vacuum pump, and is used more and more widely at home and abroad.

●Replace circulating water vacuum pump and rotary vane vacuum pump.
●No need for any working medium, no friction in the working part.
●Stable vacuum, easy to control the degree of vacuum, can be adjusted according to experimental needs.
●All parts in contact with gas are treated with Teflon (PTFE) surface, which has complete chemical corrosion resistance.
●The valve plate adopts imported material.
●SKF Swiss bearing, low noise.
●Brand motor, reasonable transmission design, self-cooling and exhaust system, can run continuously for a long time.
●Small size, light weight, easy to move, saving laboratory space.
