VP4 Top Loader Low Draw Down

The top loader is a popular model in the VP range. It fills from the top and discharges through the outlet at the top. It is ideal for use in groundwater applications for the removal of hydrocarbons. It is also ideal for use in landfill applications where the borehole is affected by excessive gas pressures. The LDD version allows a reduced well depth of liquid to be achieved.
