Remediation Solutions - Contaminant Recovery

SHP Pump

Oak Environmental's SHP (slim hole piston) pump is specially designed to meet the demands of sub-surface contaminant and contaminated groundwater extraction projects. The combination of rapid setup and low maintenance ensures efficient containment and recovery of sub-surface plumes. The SHP pump is cost effective with a proven track record on sites with chemical, oil, or gasoline spills.


  • Containment of contaminant by depression of the groundwater table
  • Removal of contaminant or contaminated groundwater from the sub-surface


  • No need to drill extra recovery wells - existing 50 mm (2 in) diameter well casings can be used
  • Maintains high pumping efficiency for extended durations
  • Low maintenance requirements
  • Self-contained and portable
  • Continuous operation from zero to 100 per cent of maximum design flow (pump is not damaged even if borehole runs dry)
