WL Vertical Reciprocating Vacuum Pump

The new WL series vertical reciprocating vacuum pumps are the upgraded and replacement products for the original W-type horizontal vacuum pumps. Compared to the W-type, they feature the following:

1. Due to the valve layout on the cylinder head and cylinder neck, the cooling water area of the cylinder is increased, resulting in a near-isothermal compression process during the gas compression, reducing power consumption by 10-15% and decreasing the land area by half.

2. Enhanced the horizontal vacuum pump piston to reduce uneven wear caused by gravity-induced sagging, minimizing wear on the piston, connecting rod, and other moving parts.

3. The WL series vertical reciprocating vacuum pumps are available in oil-free configurations.
