Sewage grinding pump station

The Mono Pumps model G60 Grifter package is an Australian designed and manufactured sewage grinding pump station for pressure sewer systems.

Pressure sewer systems are installed as an economic alter-native to the traditional gravity feed sewer. A pressure sewer system is particularly useful where it would be difficult to install the traditional gravity mains such as in areas that are hilly, extremely flat, of environmental significance, built up, or where minimum disruption is required.

The G60 Grifter pump is located in a completely dry compartment in a high-density polyethylene tank that has a totally sealed sewage collection well. The standard pressure sewer system package uses a 1000 L capacity tank and has a 60 m total pumping head capacity. A 1500 L tank is also an option and packages with higher volumes and pressure are available on request.

The package is installed at each home where sewage is collected, macerated and pumped under pressure to its destination. The pressure sewer system uses small bore pipes following the natural contour of the ground, leading to cost savings in installation and maintenance.

The pump is not immersed in the sewage so maintenance is a one-man operation, lessening the risk of sewage contamination of equipment, or spillage into the local environment. The tank has a shallow profile reducing the cost of excavation and a sloped floor that ensures pumping down to a very small residual volume. The flat ground level lid ensures that the package is visually unobtrusive.

A controller operates the package via an electronic microprocessor allowing fully automatic operation with audible and visual warning displays. Features include a diagnostic port to monitor performance characteristics of the system and a telemetry communication port.
