Sewage pumps serve a vital function in both urban and rural areas. Pumps transfer household wastewater like septic waste, raw sewage, stormwater and more. Recently there have been several innovations in raw sewage transfer type pumps that typically serve the primary sludge process at wastewater treatment plants. This typically involves pumping the sewage from a digester to a belt filter press for further treatment.
Sensors to Detect Blockages
In the photo you see here a plunger pump type raw sewage pump is equipped with pressure sensors to detect blockages in the line or a closed valve in the system. With positive displacement pumps, over pressurizing or “dead heading” a pump may cause damage to the pumping equipment. With the pressure sensors connected to the gauges and pump motor, when operating pressure reaches or exceeds the pre-set limit, the pump shuts off to reduce the chances of pump damage.
Pump Sensors to Detect Low Oil Levels
The plunger pump sewage transfer pump requires lubrication of the connecting rod and eccentrics. With a mechanical oiler system, lubrication is fed directly to the areas requiring oil and in the event of low or no oil in the reservoir the pump shuts off and sends a text message or email to the operator indicating maintenance is required. This feature is especially handy for wastewater treatment facilities facing staffing issues or limited training on how to use the pumps.
Pump Efficiency Updates
State-of-the-art variable frequency drives and flow meters help the facility limit energy usage to power required to perform the task at hand. This is better for the environment and ultimately contributes to limiting the effects of climate change as well. Variable frequency drives can be programmed to operate sludge pumps at pre-determined levels based on the power required. Flow meters indicate the specific gallons per minute (GPM) the pump is transferring contributing to a more efficient and productive process.
Sectionalized Construction and Replaceable Components
Pump manufacturers like Wastecorp design pumping equipment to limit the amount of components that have to be replaced during its lifecycle. For example, the cast iron components of Sludge Master Plunger Pumps can be easily changed with wear items like replaceable valve seats, eccentric bearings, bronze inserts and gaskets. This reduces landfill waste and the need to constantly recycle worn components.
