Dosing Pump

Dosing pumps for water and wastewater treatment
Peristaltic pumps are proven performers in water and waste treatment solving problems including:

• Dosing and metering treatment chemicals and reagents including ferric chloride (“Ferric”), sodium hypochlorite (“Hypo”), chlorine water, lime (Kalic ® or Kalkmilch), caustic soda, powder activated carbon and polymers
• Sludge transfer
• Filter press feedsTypically 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 Smart tube pumps can be interfaced with SCADA systems giving easy remote controlled dosing capabilities
