◆ Overview
The Xin'anjiang brand series JZJP type Roots water jet vacuum unit is composed of a Roots pump (also known as a mechanical booster pump) as the main pump (including an intermediate pump, which comes in both corrosion-resistant and non-corrosion-resistant types; the corrosion-resistant type achieves excellent anti-corrosion effects after spraying treatment), with a water jet pump serving as the fore pump.
◆ Features
Using an all-plastic horizontal water jet vacuum unit as the fore pump, it can pump corrosive gases. The ultimate vacuum of a single-stage Roots pump can reach 150Pa, while that of a two-stage Roots pump can reach 25Pa.
◆ Applications
This unit is widely used in processes such as vacuum drying, vacuum distillation, and vacuum concentration, and has extensive applications in industries such as metallurgy, petrochemicals, papermaking, food, and electronics. Based on customer needs, multi-stage complete units can be designed to enhance the pumping capacity and vacuum level of the unit.

Note: ① The performance in the table is based on a gas temperature of 20℃, atmospheric pressure of 1013.25hpa (equivalent to 760mmHg), relative humidity of 70%, and water circulation supply temperature of 15℃.
② Pumping speed tolerance ±10%
③ The vacuum level values in the table refer to the pressure below standard atmospheric pressure. (1mmHg = 1Torr = 133.3Pa, 0.1Mpa = 750mmHg)
