SEWAGE GRINDER PUMPS
Sewage Grinder pumps are designed to handle raw sewage pumping jobs, just like the Sewage Ejector pumps. However, grinder pumps are much more powerful. These pumps grind up sewage into a slurry and pump it at a very high pressure to its destination.
- Powerful Grinding Action: Equipped with sharp cutting blades, these pumps macerate solids like toilet paper, wipes, and organic waste into a slurry, preventing clogs in high-pressure or long-distance sewage lines.
- High-Pressure Performance: Starting at 2.0 HP with 1-1/4" NPT discharges, our grinder pumps handle high head pressures (minimum 30 feet) and long runs (up to thousands of feet), perfect for homes below municipal sewer lines or with pressurized systems.
- Durable Construction: Made from corrosion-resistant materials like cast iron and stainless steel, ensuring long-lasting performance in harsh wastewater environments.
- Easy Installation: Submersible design with internal capacitors (no control panel needed for most models) and pre-wired float switches for automatic operation, ideal for residential setups.
- Trusted Brands: Featuring top-quality pumps from Liberty Pumps, Little Giant, Zoeller, and Ashland, renowned for efficiency and durability in residential applications.
GRINDER PUMPS OR EJECTOR PUMPS.... WHICH DO YOU CHOOSE?
PLEASE NOTE: Grinder pumps must be used in scenarios where there will be at least a minimum of 30 feet of head pressure put on them. If they do not have to pump against at least this much back pressure, the motor will begin to spin at an extremely high rate of RPMs causing it to burn up fairly quickly. Therefore, if you are not pumping into a shared sewer main or have less than 30 feet of head, you do want a Sewage Ejector pump not a Sewage Grinder pump.
You should only use a Sewage Grinder Pump when one the following apply to your application:
- When pumping to city sewer.
- When pumping to a pressurized sewer main.
- When pumping a very long distance (1000 feet or more)
- You have a high vertical distance to lift the water (minimum of 30 feet)
Below are the scenarios when a Sewage Ejector Pump will work best:
- When pumping sewage to a septic tank.
- When pumping sewage to a gravity sewer main.
- When pumping sewage short distances (750 feet or less)
- You have a low vertical distance to lift the water (under 70 feet)
IMPORTANT CONSIDERATIONS
- Not for Septic Tanks: Grinder pumps are not recommended for septic systems, as finely ground slurry disrupts the natural separation of solids and liquids, reducing treatment efficiency. Use sewage ejector or effluent pumps instead.
- Minimum Head Pressure: Requires at least 30 feet of head pressure to prevent motor burnout from excessive RPMs. Ideal for pressurized sewer mains or high lifts (30+ feet) over long distances (1,000+ feet).
- What to Avoid: Do not flush feminine products, diapers, wipes, kitty litter, oils, or paints, as these can clog the pump or reduce efficiency.
- Power Backup: Consider a generator to prevent backups during power outages, as grinder pumps rely on electricity.
