What Are Grinder Pumps?

Grinder pumps are engineered to shred solid waste into smaller particles, ensuring smooth and efficient flow through wastewater systems. Unlike traditional submersible pumps, which simply move liquids, grinder pumps have built-in macerators (shredders) that chop solid materials, like food waste, rags, and other debris, into a fine slurry.

This is crucial in systems with narrow or pre-existing pipes where larger solids might cause clogs or blockages. By reducing solid waste to a smaller size, grinder pumps ensure that materials can move more easily through the system without the risk of jamming or obstruction.

How Grinder Pumps Work:

Submersible grinder pumps operate by utilizing a cutting mechanism, often in the form of rotating blades or cutters, that break up large solid particles in wastewater. These systems are typically designed to work at higher RPMs (revolutions per minute), enabling them to slice through waste material with great efficiency. The result is a much finer slurry of wastewater that can be pumped through smaller-diameter pipes, reducing the need for costly pipe replacements and minimizing the risk of clogging.

Why Do You Need a Grinder Pump?

In situations where traditional solids handling pumps cannot handle solid waste or when there is a need for a higher-pressure system, submersible grinder pumps come in as the solution. The GRIX and G2 Series are designed specifically to tackle difficult pumping conditions and ensure that wastewater is moved efficiently, even through narrow pipes or over significant vertical distances. These high-pressure pumps are commonly used in:

• Domestic Sewage
• Industrial Sewage
• Municipal Water & Wastewater Systems
• Commercial Buildings
• Septic Systems

If you’re dealing with wastewater systems that have to push waste up considerable heights or through extended piping networks, having a grinder pump ensures the wastewater moves without clogs or backups.

When it comes to managing wastewater and sewage, having the right pump can make all the difference. For those in need of reliable, high-performance submersible pumps, the GRIX and G2 Series by BJM Pumps® grinder pumps are top choices for breaking down solids in wastewater systems. Whether you’re dealing with residential, commercial, or industrial sewage, these high-head pumps are designed to handle the toughest applications effectively.

GRIX Series: Cutting-Edge Grinder Pumps for Tough Applications

The GRIX Series is a range of electric grinder pumps designed for submersible applications. They come with an integrated macerator that breaks down solids in wastewater, allowing for smooth transport along narrow, often pre-existing pipes. The main components of these pumps are constructed from cast iron GG20, ensuring durability and long-lasting performance.

Key Features:

• Built-in macerator to break down solids and prevent clogs.
• Cast Iron GG20 construction for strength and resilience.
• Available in 60Hz, 230/460V options.
• Relay installed for smooth operation of the float switch on 3-phase motors.
• EVO Version features a double mechanical seal in the oil chamber with an accessible oil chamber for easy maintenance.
• Carbon/Ceramic (CA/CE/Viton) motor side materials.
• SIC/SIC/Viton impeller side materials.

Applications:

• Domestic sewage systems.
• Wastewater with suspended solids.
• Situations requiring high pressure (head).

The GRIX Series is perfect for domestic, commercial, and municipal sewage applications where efficiency, reliability, and power are paramount.

G2 Series: Powerful Electric Grinder Pumps for Heavy-Duty Needs

The G2 Series represents a more powerful option for handling liquids with suspended solids, designed for situations that require high pressure. These submersible electric pumps are built with a grinding system to ensure that the waste is reduced to small particles that can be easily transported. Their robust construction makes them ideal for both commercial and municipal use, providing reliable performance under demanding conditions.

Key Features:

• Main components made from cast iron GG25 for added durability.
• Available in 60Hz, 460V options.
• Built-in macerator at the inlet to break down solids efficiently.
• Standard Seal Minder® Probe to monitor the condition of the seals.

Applications:

• Commercial buildings
• Municipal sewage systems
• Handling liquids with suspended solids.
• When high pressure (head) is required.

With the G2 Series, you get a high-performance grinder pump that can move wastewater through long distances or vertical heights, even when dealing with complex waste types.

Conclusion

Both the GRIX and G2 Series grinder pumps are designed to meet the needs of municipal, commercial, and residential wastewater systems that deal with solid waste and high-pressure requirements. Whether you’re looking for a pump to handle domestic sewage or need a heavy-duty solution for industrial or municipal applications, these submersible pumps provide unmatched durability, efficiency, and reliability. Investing in a grinder pump like the GRIX or G2 Series will ensure that your system remains smooth, efficient, and free of clogs, even in the toughest conditions.
