The Omni Grind (OGV) is rated for low to medium heads, up to 95 feet or 41 PSIG, while the Omni Grind Plus (OGP) is designed for higher heads, up to 180 feet or 78 PSIG at 10GPM. The project Engineer or a Barnes  Pressure Sewer specialist can advise the expected head based on the system piping design, or you can simply select the OGP for any head up to 180 feet.

No. In order to provide the best possible grinder pump life, we have chosen to use grinder pumps with the proven centrifugal vortex design. Progressing cavity pumps continuously wear, and the wear is accelerated under certain operating conditions; centrifugal pumps by their nature are not affected by pressure extremes or high flow rates.

Barnes offers an extensive line of engineered pressure sewer systems with available depths up to 20 feet and diameters up to 6 feet. Larger capacity stations are readily available for your specific needs.

The size of the external cover (effective
diameter) depends primarily on the riser
diameter; an 18" diameter was chosen to
reduce the visual impact of the cover in
the homeowner’s yard. The specifications
calling for a 24" diameter require a worker
to enter the basin to perform shutoff valve
maintenance. With the removable POD design,
all maintenance is performed from topside
eliminating the need for confined space entry.

The EcoTRAN is provided with brass padlocks for both the basin cover and the alarm box.

The EcoTRAN has been thoroughly tested and qualified to NSF/ANSI 46, a specification that requires successful operation despite the occasional entry of a wide range of challenging materials, including cloth.
