1、 Overview of JZJW Roots reciprocating vacuum pump unit:

The JZJW series Roots oil-free reciprocating vacuum unit is composed of a ZJ series Roots vacuum pump as the main pump and a WLW vertical oil-free reciprocating vacuum pump as the front stage pump connected in series. Overcoming the disadvantages of high ultimate pressure and low pumping rate under constant pressure of WLW vacuum pump, while retaining the advantages of fast operation and high pumping rate of ZJ series Roots vacuum pump. So the JZJW series Roots oil-free reciprocating vacuum unit is widely used in the chemical industry for vacuum distillation, vacuum evaporation, dehydration crystallization; In the processes of freeze-drying in the food industry and vacuum drying in the pharmaceutical industry.

Due to the use of oil-free self-lubricating materials in WLW vacuum pumps, clean vacuum can be obtained. Therefore, the JZJW series Roots oil-free reciprocating vacuum unit can collect gases that cannot be solidified or compressed in high vacuum systems, such as pentaene, benzene, toluene, etc., after installing an exhaust gas collection device at the exhaust port, avoiding environmental pollution caused by their low boiling point and difficult collection.

2、 Advantages of JZJW Roots reciprocating vacuum pump unit:

The JZJW series Roots oil-free reciprocating vacuum unit is a new product developed in cooperation between our factory and national research institutions. Its advantages include significant energy saving, small footprint, water saving, and low noise, making it an ideal new product for environmental protection. vacuum pump unit

1. High ultimate vacuum degree, long-term stable vacuum degree.

2. The pumping rate is higher under higher vacuum conditions.

3. The motor has low power and energy consumption.

4. Due to the lack of oil lubrication in the overcurrent section of the JZJW series Roots oil-free reciprocating vacuum unit, a tail gas collection device can be installed at the exhaust port of the unit to collect gases such as benzene and toluene that cannot be solidified or compressed in high vacuum systems.

5. No secondary water pollution, reducing the pressure of pollution control. JZJWLW type Roots reciprocating vacuum pump unit
