One, WLW reciprocating pump model significance: Vertical oil-free vacuum pump model description illustrates two, WLW reciprocating pumps range: WLW W reciprocating pumps are reciprocating pump replacement products, is to get a rough vacuum of major equipment. As a fully sealed unit to achieve a complete separation of the crankcase and cylinder; plus the use of a self-lubricating material piston rings, they achieve an advanced oil-free. Because no sewage discharge, so WLW reciprocating pump is particularly suitable for vacuum distillation chemical, pharmaceutical and food industries, vacuum evaporation, vacuum drying, vacuum concentration, vacuum dipping process. In particular the application of cleaning required to clean a high vacuum or gas recovery environment. WLW reciprocating pumps needed to overcome the pollution caused by the lubricant. If applied to the extraction of flammable gases, or when the compressors, should I make a special order request. Three, WLW reciprocating pump features: 1, WLW reciprocating pumps and high ultimate vacuum (4.5-15mmHg). 2, WLW oil-free reciprocating pump: the PTFE piston ring lubricant to ensure the normal operation of the cylinder does not need to avoid the oil pollution, waste and forget refueling accident caused. 3, WLW reciprocating pumps can change accessories for pumping corrosive media material. WLWF series lined stainless steel or titanium materials, the ability of various types of acids, alkalis, organic solvents corrosion. 4, WLW reciprocating pump energy, water, saving floor space. 5, the average wear rate WLW reciprocating pump cylinder, piston rings, crankshaft, crosshead greatly reduced, longer operating life, long life (4-10 times). 6, WLW reciprocating pump by eliminating the inferior transverse vibration and reduce noise. 7, simple and beautiful appearance, operation, and maintenance. 8, WLW reciprocating pumps can be composed with the Roots Roots vertical reciprocating pump on an oil-free vacuum unit Kai Qing Shanghai Pump Manufacturing Co., Ltd. is a company specializing in research, manufacture, production and sale of pumps technology companies. The main products are: vacuum pump, vacuum unit series, series water ring vacuum pumps, rotary vane vacuum pump series, Diaphragm series, submersible mixer series, the most professional vacuum pump manufacturer Shanghai direct selling, all three bags of products, and look forward to you cooperation, please call the free service hotline: 4000-889-202.
