Safely pumping electroplating wastewater from pump sump tanks

Electroplating wastewater containing acids, alkalis, and particulate matter is pumped from a pump sump into a neutralization tank. The solution must safely handle corrosive media and operate continuously.

Solution
FLUX F 640 PP submersible centrifugal pump and three-phase motor

Task

Pump large volumes of electroplating wastewater from a pump sump into a neutralization tank. The fluid contains acids, alkalis, and dirt particles and is collected via several channels.

Requirements
  • Resistant to acids and alkalis  
  • Conveying media containing particles  
  • Various immersion depths possible
Solution in Detail

The F 640 PP centrifugal immersion pumps is installed in the pump sump and is submerged directly in the fluid. The motor remains outside the liquid. A strainer protects against particles, and the fluid is pumped into the neutralization tank.

Result

Safe transport of corrosive substances such as acids and alkalis

Reliable operation in the pump sump

Particle filtration via a screen protects the pump

Automated drainage via level monitoring

Flexible adjustment to different immersion depths
