Features/Product Advantages

Pressure-tight, sealed collection tank suitable for both underground and above-ground installation
Flexible inlet selection
Large-capacity tank
Includes piping, level control system, control switches, and pumps

Construction

Plastic collection tank available as a single- or dual-pump system; suitable for underground installation or installation inside a building.

Applications

Installation inside a building (above-ground) as a lifting system.
Installation outside a building (underground) as a collection tank.
Ensure backflow prevention is implemented when:
The discharge point is below the backflow level;
Wastewater from the discharge point cannot drain away by gravity.

Fluids

For collection and pumping in commercial applications:

Wastewater with or without sewage
