JZJ2B(S)W Series Roots Vacuum Pump Unit
The JZJ2B(S)W series Roots-liquid ring closed-loop vacuum unit utilizes a ZJ Roots pump as the main pump and a 2BV/2BE/2SK liquid ring vacuum pump or a Roots-liquid ring vacuum unit.
JZJ2B(S)W Series Roots Vacuum Pump Unit
I. Applications
The JZJ2B(S)W series Roots-liquid ring closed-loop vacuum unit utilizes a ZJ
Roots pump as the main pump and a 2BV/2BE/2SK liquid ring vacuum pump or a
Roots-liquid ring vacuum unit as the backing pump. It can be used not only to
extract general gases but also gases containing moisture and small amounts of
dust. Compared to conventional mechanical vacuum pumps, it is resistant to oil
contamination, moisture, and fine dust. It is an ideal vacuum extraction system
for drying, dehydration, and vacuum degassing in industries such as textiles,
food, chemicals, and pharmaceuticals. II. Features
1. The JZJ2B(S)W series Roots liquid ring vacuum units utilize the highly
efficient and energy-efficient 2BV liquid ring vacuum pump as their backing
pump. Consequently, the JZJ2B series Roots liquid ring vacuum units offer
advantages over the JZJ2SW series Roots liquid ring vacuum units, including
higher efficiency, compact structure, zero leakage (the 2BV series utilizes a
standard mechanical seal design, unlike the 2SK series' packing seal), corrosion
resistance (the 2BV series utilizes a stainless steel impeller), and a higher
level of protection.
2. The backing pump for Roots liquid ring vacuum units typically uses water
as the working fluid, but can also operate with organic solvents (such as
methanol, ethanol, xylene, and acetone) or other liquids. Using the backing pump
as a closed-loop system significantly reduces environmental pollution and
significantly improves organic solvent recovery. The ultimate vacuum level is
determined by the saturated vapor pressure of the working fluid.
