Comparing to table type, the vertical type owns larger sucking rate, it’s the ideal choice for rotating evaporator whose volume above 5 liters. Plus, the vertical type is equipped with castors to move freely in laboratory or workshop.

2XZ rotary vane vacuum pump is a double-stage high speed direct connection structure rotary vane pump. The pump connect shaft with electrical machine, which has high rotating speed, small shape, compact structure and good mobility working mode. The working medium is oil, large sucking rote, it can separately operate or use as the backing pump and pre-pumping of all kinds of high vacuum system.

YH diaphragm vacuum pump is one of the transfiguration vacuum pump, it is free of any media, no pollution, no friction, no heat generation, thus, it has longer service life than other pumps. Light weight and small volume, powerful pump force, comparing to other type, the price is higher.
