The blue cylindrical pre-filter, a sump pump with a heating ring and the new custom-made heating blanket, are all new additions to the Pump-Thru Barriers overall versatility. The pre-filter canister itself has dramatically improved the longevity of the internal dirt filters built into the units.

What Is an SPI Pump-Thru Barrier?

The SPI Pump-Thru Barrier is a portable containment unit for the rapid removal of rainwater in high volumes. The Pump-Thru Barrier uses a sump pump with SPI-patented media for efficient hydrocarbon removal. Rainwater is pumped in the Pump-Thru Barrier and passively drains as the media removes the oil sheen. In the event of an oil spill, the unit seals off completely to contain the spill.

Pump-Thru Barriers feature an internal filter that cleans rainwater before reaching the media. During a spill, oils are diverted to a return system that flows back to the containment area. Overflow directs back to the containment area until the sump pump is turned off. In rainstorms, the rainwater pumps into a portable Pump-Thru Barrier with dirt and oil sheen filters that prevent clogs. These filters can be quickly replaced.

In colder climates, Pump-Thru Barriers have thermal heating blankets to protect the unit housing and the external water filter. An additional sump pump pre-filter can also be used and cleaned as needed.

The Pump-Thru Barrier is best used in containment areas where you need assurance that no oil sheen will discharge.

Pump-Thru Barrier Maintenance Instructions

The Pump-Thru Barrier is outfitted with an external water filter and support brace. This external filter removes dirt down to 35 microns before entering the internal filter. With our custom heating blankets, our Pump-Thru Barriers can perform in below-freezing temperatures. To maintain the Pump-Thru Barrier throughout use, perform the following steps:

  1. Insert pump barrier canister.
  2. Align canister holes with barrier holes and insert 12 ¼ hex bolt with gasket washer and tighten. Be careful not to overtighten.
  3. Insert the sheen filter. Push down until it stops, and make sure the gasket ring is flipped up and not down.
  4. Insert barrier dirt filter. Push filter down until it stops.
  5. Insert the retaining ring to hold the dirt filter in place.

Pump-Thru-Barrier Oil and Water Separator

The SPI Pump-Thru-Barrier is outfitted onsite with an external water filter and support brace. The external filter removes dirt down to 35 micros and allows the system to capture the fine dirt prior to getting into the internal dirt filters.

The sump pump is turned on and the flow is adjusted with a max flow rate on the 24” unit of 35 gpm.

Cold Weather Operation of the Pump-Thru-Barrier

Our custom heating blankets have been tested for temperatures below -40 degrees in extreme conditions. Our custom heating blankets allow for safe oil containment in freezing temperatures. Learn more about our cold weather oil containment solutions.
