ELIMINATING DAMAGE

TO SUBMERSIBLE TURBINE PUMP SUMPS

PROBLEM

One of the more common problems facing gas station owners today is surface water and contaminants leaking into the sump from the tank field and corroding or otherwise damaging the sump equipment. Once this damage occurs, the sump equipment will eventually need to be replaced to meet regulatory requirements.

SOLUTION

Once water breaches the sump lid, it will collect in the sump. The Petropro Convex Sump Cover eliminates this problem. Constructed of a highly durable industrial-grade casting, it is made to withstand the harshest environments and high traffic areas.

The Petropro Convex Sump Cover will remove the surface water from the tank field and filter it away from the sump and into the surrounding gravel leaving your sump pit dry.

ADVANTAGES
  • 1 Stops water from going into the sump
  • 2 Provides ventilation
  • 3 Provides a new and revolutionary method
  • 4 Saves up to $50,000 per tank

THE DIFFERENCE

This solution provides many layers of protection which start with the convex shape of the sump cover. The convex shape allows for water to flow away from the top of the lid to the sump cover drainage holes.

The drainage holes allow for water to be absorbed by the compacted gravel that sits beneath the holes while any excess surface water can drain along the side of the sump ring wall into the gravel beneath the sump ring. The drainage holes also provide ventilation, reducing the pressures of gases which can damage the sealants typically used on the market today.

An additional advantage of the solution’s design is its quick installation which only takes a few steps.

Petropro ultimately reduces operational interruptions and downtime as well as ongoing maintenance costs and concerns.

QUICK START

GUIDE

STEP 1

It is advised first to confirm that the inner diameter of the sump ring or sump skirt is 1 to 2 inches wider than the existing diameter of the sump shell.

STEP 2

Place the sump ring on each existing sump cover and mark it wider than the existing concrete or asphalt by 1 to 2 feet.

STEP 3

Remove existing sump collar and lid.

STEP 4

Remove existing materials such as concrete, dirt, and other obstructing elements found around the sump shell’s marked surface and no less than 6 inches below the frost line.

STEP 5

Fill the hole with gravel to accommodate the new sump ring or skirt as needed.

STEP 6

Fill the opening around the sump by about 6’’ – 8’’ inches below the frost line. Compact the gravel thoroughly to prevent further settling.

STEP 7

Level the top edge of the sump ring with the ground, ensuring it is flush with the surface of the concrete.

STEP 8

Place the round form frame as shown to ensure that, as the concrete is poured, space is left for the required amount of gravel needed under the sump ring holes.

STEP 9

Fill and compact the space under the sump ring with gravel using a wooden or metal stick between the ring holes.

STEP 10

Place the new cover and pour the concrete as required to the finish grade level.
