Each household’s wastewater system requirements are different and depend on a number of underlying factors. Flow rate, regulatory compliance, plumbing system, solid content, and daily requirements matter a lot. This is why choosing the right pump can help increase reliability and efficiency and reduce frequent repairs.
There are two common types of wastewater pumps: sewage pump and grinder pump. Read this full blog to find which is the best fit for your wastewater system.
What is a Grinder Pump?
This type of pump is perfect for you if your house is unable to pass the waste through natural gravity. A grinder pump works by grinding the household waste from toilets, sinks and washing machines. This waste is then directed to the nearest municipal sewer system. It works with the use of a float switch, which turns the motor on once the desired level of waste is reached.
The pump then starts to chop the waste into a slurry, which can be easily managed by the sewage system. The best benefit of these pumps is their ability to handle solid waste. Unlike other pumps, grinder pumps are perfect for managing low-density solid waste. Additionally, these are highly efficient for long-distance waste transport without the need for a slope.
However, it is recommended not to flush diapers, hygiene products, oil, laundry, plastic and metal. The metal blades in this pump can handle small solids, but heavier solids can lead to pump failure. Mindfully using a grinder pump can save money on costly repairs and frequent maintenance.
What is a Sewage Pump?
Unlike a grinder pump, which can only handle a low volume of waste, a sewage pump can handle more. These are also called ejector pumps and work by rotating an impeller. This device uses an electric motor, which helps in generating pressure. This allows the fluid waste to flow up through an impeller, which leads to the discharge pipe. Additionally, the cast iron coating of these pumps allows them to be highly reliable to transfer untreated waste.
A sewage pump is a preferred choice for the wastewater management industry and municipal corporations. This is because it is designed to allow the waste to pass through the pipes. This ability allows it to withstand challenging fluids and high flow rates. Such a pump is perfect for commercial applications, including factories, malls, and manufacturing industries. This helps in unclogging the pipes and directing the wastewater away from the commercial buildings.
Key Differences Between Grinder and Sewage Pumps
The following are some key differences between a grinder pump and a sewage pump:
|
Point of Difference |
Grinder Pump |
Sewage Pump |
|
Performance |
These pumps work well in residential settings and can handle low-density solid waste. |
These pumps are suitable for commercial settings and offer a high flow rate. These can handle a decent amount of solid waste. |
|
Size |
Can pass the solids for 1-1/4 inches. |
Can handle solids up to 2 inches in diameter. |
|
Capabilities |
These are best suited for a smaller volume of waste of round 35-70 gallons per minute. |
Have high capabilities and can pump up to 200 gallons of raw waste per minute. |
|
Maintenance Needs |
Every month proper cleaning must be done to avoid blockages in pump components. Monitoring the pump performance and proper lubrication of bearings can help in increasings it performance. |
Cleaning the intake and discharge pipe is important to avoid clogging. The pump seals must be replaced if they show signs of damage. The impeller must be clean to avoid noises and performance issues. |

Lifespan |
8-10 years |
5-7 years |

Power Consumption |
500-1200 watts |
1/3 hp watts |
Choosing the Right Pump for Your System
- Grinder Pump
If you are looking for a reliable pump to manage grey water for residential use, a grinder pump is best. You can consider this pump for low-density waste. If the pipe is smaller, this pump is highly recommended as it can handle pressure. If your slope is not inclined to connect with the main system, these can work well.
- Sewage Pump
Commercial and heavy applications can work well with a sewage pump. Wastewater with larger solid waste can use this type of pump. These pumps can work effectively with larger pipes as they can handle challenging waste. Additionally, if you are not connected to the main system, these pumps can help.
Conclusion
Selecting the best pump for the wastewater system requires many prior considerations and factors. You must understand the nature of the solid waste, energy requirements, pipe fittings, and size and distance. For further guidance and clarity, you can consult experts such as BJM Shredder Pumps. This can offer you tailored advice and help in resolving all doubts. This way, you can understand if you should buy a grinder pump or a sewage pump.
