Mibay Water cooling TXLGB140 series Water-Cooled TXLGB140 Series Dry Screw Vacuum Pump
Key specifications
Description
Dry screw vacuum pumps operate with two screw rotors rotating in opposite directions. This mechanism traps the medium to be pumped between the cylinder and the screw chambers, transporting it to the gas discharge. The advanced screw design results in lower electrical energy consumption compared to standard designs and reduces the heat load on the compressed gas. Cooling is achieved via high-performance air cooling (eliminating the need for cooling water) or an indirect cooling method that ensures uniform temperatures throughout the pump body, eliminating cold spots and providing a thermally stable water jacket. The advanced screw design allows for best-in-class hydrogen pumping capabilities. Water cooling is available via direct water cooling or radiator cooling with air-cooled heat exchangers.
