SPI's Portable Pump-Thru Barrier™

For Removal of Hydrocarbons to Non-Detectable Levels, Providing 100 % Effective Fuel/ Oil Protection 

SPI developed the Portable Pump-Thru-Barrier™ for containment areas that require rapid removal of high volumes of rainwater while disallowing any oil sheen or spill to be released. SPI’s Pump-Thru Barrier™ System incorporates the use of a sump pump in conjunction with our Patented Media for efficient hydrocarbon removal. Rainwater is pumped into the Pump-Through-Barrier™ and passively drains through the SPI Media removing any oil sheen whatsoever. In the event of a Major Spill, the unit completely seals off to contain the spill.

The Pump-Thru-Barrier™ has internal dirt filters that clean the rainwater before it reaches the Petro-Barrier™ Media. In the event of a Major Oil Spill, the Pump-Thru-Barrier™ instantly shuts off all flow and prevents any oil from reaching the surrounding environment. All oils are diverted to a return system that flows back into the containment area after the system has shut down. The overflow is directed back into the containment area until the operator shuts down the sump pump. This is a system that can be trailer mounted to allow companies to pump out several areas in a number of locations.

During a rainstorm, the rainwater is pumped into the Portable Pump-Thru Barrier™ Unit which incorporates the use of dirt and oil sheen filters that prevent the Petro-Barrier™ from clogging. These filters are easily removed and replaced in minutes. For colder climates, the Pump-Thru-Barriers™ are outfitted with Thermal Heating Blankets that protect both the Unit Housing and the External Water Filter. We have also added an additional Sump Pump Pre-Filter that can be cleaned as needed.


The Portable Pump-Thru Barrier™ can be installed in any containment area where you need to be sure no oil sheen is ever discharged from your facility. The Portable Pump-Thru Barrier™ enables companies to install an effective Oil Spill Containment System after the fact, that prevents pooling water and many hours manual pumping. If an oil sheen is visible, it is necessary to treat the water onsite or have a tank truck haul the water off for treatment somewhere else. Worse yet, if the water is not pumped out and an oil spill occurs, will the system have the holding capacity it needs? Pump-Thru Barriers™ remove oil sheen to less than 3 ppm but in most cases to non-detectable levels. No other system works 24/7/365 days a year providing the protection that SPI’s Pump-Thru Barrier delivers.

SPI’s Pump-Thru Barrier™ Removes and Stops:

  • Diesel
  • Transformer oil
  • Heating oil
  • Jet fuel
  • Kerosene
  • Gasoline
  • Crude oils
  • Hydraulic oil
  • Other hydrocarbons
In the picture to the left, diesel fuel was leaking from a peak generator site into the containment area with no discharge, costing right at $20,000.00 a month for disposal during the rainy season in Vermont. SPI’s Pump-Thru-Barriers™ have been installed for more than 5 years now, so imagine the money that has been saved. When large quantities of diesel fuel are absorbed over time, the flow rate starts to diminish and the Barrier Cartridge needs to be replaced.

List of Services

Pump-Thru-Barrier Oil/Water Separator

SPI Pump-Thru-Barrier™ is outfitted onsite with a external water filter and support brace. The external filter removes dirt down to 35 micros and allow the system to capture the fine dirt prior to getting into the internal dirt filters. The sump pump is tuned on and the flow is adjusted with a max flow rate on the 24” unit of 35 gpm.

Cold Weather Operation Pump-Thru-Barrier

Custom heating blankets that have been tested for temperatures below -40 degrees in extreme conditions. The following test was conducted at the SPI facility with temperatures of -12 F and not rising above 32 F for 8 straight days. The blankets were installed on the Pump-Thru-Barrier™ housing and external water filter in December 2013 and removed April 1, 2014. Installed in the water vessel is a water heater that kept the water free of ice also through the time period. The internal temperature inside the Pump-Thru Unit was a warm 68 degrees.
