The P2K series pumps shown in Section 2 are the most frequently used type for side slope landfill leachate removal. These pumps’ size and materials are compatible with leachate, well dewatering, and methane condensate streams. When properly selected and installed, they offer economical and reliable service. The pumps are a component design so they can be easily serviced in the field and require little regular maintenance. All pumps shown are available in single-phase 230 volt and three phase 230 or 460 volt service.
Pump model numbers represent the nominal flow in gallons per minute, for instance the P2K-40 is rated 40 GPM at its peak efficiency. The numbers after the model shown on the curves are the number of stages (or impellers). For example, the P2K 40-3 is a 3-stage pump. The pumps included in this catalog are considered "low head" models which meet most project requirements. Higher head (and flow) pumps are available upon request.
When selecting a pump the minimum and maximum performance point must be considered. Because the pumps are lubricated by the pumped fluid and have a "floating shaft," it is critical to correctly size the pump, particularly when there may be multiple pumps discharging into a common force main. If the pump is allowed to exceed the flow on the right of the recommended performance curve, the pump may develop high thrust loads and experience excessive wear and vibration, high motor amperage, and cavitation. Selection of a pump operating on the far left side of the recommended performance range might be unable to produce proper flow and could result in excessive bearing wear due to the lack of lubrication or motor overheating in some applications.
If the pump performance selection involves widely variable pressure conditions, there are several solutions to eliminate possible problems including mechanical and electrical approaches. Please call to discuss options or concerns.
The "typical specifications" provided are for a standard SidesloperTM system package, which offers the best value and is readily available for delivery. To complete the specifications, include the pump model number, flow and head ratings, phase and voltage, and the maximum riser length and hose size. Custom system specifications are available upon request.
