Water is a precious commodity, drinking water quality and treated waste water affects health and the environment requiring reliable, forgiving pumps with infrequent servicing - proven features of the Verderflex pump family dosing reagents, transferring sludges or feeding filter presses

Pumps for the (waste) water treatment industry

Verderflex peristaltic pumps are manufactured in the EU within ISO 9001, ISO 14001 and ISO 45001 accredited facilities.

Typically both hose and tube pumps are used as chemical dosing pumps accurately and repeatedly delivering a wide range of chemicals whilst addressing the problems of the liquid:

  • Lime is abrasive causing diaphragm pumps to clog due to lime’s viscosity and progressive cavity pumps to suffer from abrasive wear
  • Hypo offgases when pumped causing dosing pumps to vapour lock resulting untreated liquid streams
  • Polymers are often shear sensitive and progressing cavity pumps reduce the particle size leading to increase chemical usage
  • Sludge’s often have a high grit content creating abrasive wear problem for many pumps with rotary pumps suffering from ragging problems on primary sludge.
  • Additionally, Verderflex Vantage 5000 pumps can be interfaced with SCADA systems giving easy remote controlled dosing capabilities
