Neptune

Neptune Nimble Skids are complete metering systems ready to use with any bulk or intermediate bulk chemical container.
Standardized design allows the user to customize by selecting the most popular options.

Working within this framework allows shipment of most units within 5 to 10 days.
Controls may also be added.

One and two pump systems fit within an 18″ x 30″ footprint.

Suction manifold includes inlet valve and strainer, a branch connection with valve for calibration column and a valve at
each pump suction. Discharge manifold includes a valve at each pump discharge.

Three and four pump Nimble Skid systems are also available with a maximum footprint of 24″ x 46″. Containment is available for all systems.

VERDERFLEX

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 feeds

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 Smart tube pumps can be interfaced with SCADA systems giving easy remote controlled dosing capabilities
