NoVault 2 (NV2) Pump Station

The Excel Fluid Group NoVault 2 (NV2) pump station enclosure (above ground valve chamber) gives you full access and control of your lift station pumping equipment without the hassles of confined space entry. Built with rugged aluminum and feature packed for operational convenience, the NoVault pump station is, by design, one of the most versatile units on the market today.

The EXCEL NoVault pump station is the “Next Generation” in municipal wastewater collection system management. Our engineering department can modify standard construction features to fit almost any job specific requirement. Excel Fluid Group is your single-source supplier for complete lift stations including concrete, structural HDPE or fiberglass basins and your choice of controls and telemetry.

A sanitary wet well is a dangerous confined space that has claimed many lives in years past. This places a special obligation of care on all those involved in servicing and installing pump stations.

Excel Fluid Group has worked with municipalities throughout North America to develop the Excel NoVault Pump Station to minimize your risk, by providing a well designed, safe installation where all maintenance can be performed without entering the wet well or valve vault.

Long-term operating and maintenance costs are substantially reduced through superior design and the use of quality equipment and materials.

Compact Layout

The Excel NoVault design incorporates the valves and lift station controls within the footprint of the main wetwell. For installation in areas with limited space the Excel NoVault provides all of the features commonly found in conventional lift stations.

The NoVault pump station is the designer’s dream come true; with the smallest footprint available and aesthetics to blend into your environment it has become the first choice for many developers, consultants and communities.
