VAS - Special Vertical Acid Pumps

 Three types of design :

• 1) discharge through side branch for small sizes
• 2) discharge through head for large sizes
• 3) dry installation out of the tank

 Grease-lubricated ball bearings
 Absence of radial load on column bearings because of the concentric discharge.
 Column bearings by the pumped liquid
 Simple shaft sealing by throttle bush with leakage back to the tank
 Auxiliary packing rings preventing acid vapors (for safety and maintenance)
 Axial balancing by front and rear casing wear rings
 Mating faces protected against acid corrosion
 Threads protected by cap nuts and O-rings
 Multi-stage construction available upon request
