- High corrosion resistance due to compact and unique design
- Wide range of highly corrosion-resistant materials guarantees high durability of the pump
- Reliable design ensures longer maintenance-free operation
- Easy assembly and maintenance of the pump
- Low plant down time due to high reliability
The VAS acid pump range has been designed to meet the requirements in H2SO4 plants such as
- Absorption tower
- Drying tower
- Heat recovery system
- Symmetrical diffuser casing design minimizes radial loads and shaft deflection ensuring longer pump service life
- Auxiliary packing rings to prevent acid vapors and minimize corrosion
- Non-contacting shaft sealing with throttle bushing which reduces head pressure and minimizes leakage overflow
- Easy assembly and installation of the pump to the tank due to symmetric design with circumferential mounting plate
- Fully protected bolts against corrosion allow easy assembling and dismantling of the pump
- High efficiency and low net positive suction head (NPSH) due to closed impeller
