Enhancing Sewage Treatment with HOMA's GRP Series Grinder Pumps

Modern sewage systems are facing increasing demands as populations grow, infrastructure ages, and the presence of non-biodegradable solids—like wipes, plastics, and packaging materials—continues to rise. For wastewater systems to operate efficiently, especially in areas with low-flow conditions or long discharge runs, grinder pumps play a critical role. These pumps are designed to reduce solids into fine slurry, preventing clogs and improving flow throughout the system.

Among the top-performing products in this space is the GRP Series from HOMA Pumps. Engineered with robust materials, powerful motor options, and a proprietary cutter system, HOMA’s grinder pumps are trusted in residential, commercial, and light municipal applications. They’re purpose-built to shred the toughest materials and keep sewer lines flowing—even in the most demanding situations.

This blog will explore the advanced features of HOMA’s GRP Series Grinder Pumps, the industries and applications they serve, and how Process & Power—with offices in Memphis and Jackson, Tennessee; Springdale and Little Rock, Arkansas; and Tupelo, Mississippi—can help you install and maintain these high-efficiency systems for long-term success.

The Role of Grinder Pumps in Modern Wastewater Systems

Grinder pumps are designed to process wastewater containing solids by macerating the solids into smaller particles, creating a homogenous slurry that can be easily pumped through small-diameter pipes. This is especially important in:

  • Low-pressure sewer systems

  • Remote or rural installations

  • Basements or below-grade structures

  • Commercial kitchens and multi-family dwellings

Without a grinder pump, solids can accumulate in the pipes, causing backups, system damage, and costly maintenance issues. Unlike standard sewage pumps that simply pass solids through, a grinder pump cuts and pulverizes solids before transport, ensuring reliability even in the face of difficult waste streams.

Overview of the HOMA GRP Series Grinder Pumps

The HOMA GRP Series is a line of submersible grinder pumps designed for residential, commercial, and light municipal wastewater applications. What sets these pumps apart is their exceptional ability to shred soft solids and fibrous material while delivering reliable, energy-efficient performance.

Key Specifications:

  • Motor sizes from 1 to 15 horsepower

  • Single- and three-phase models

  • Capacities up to 130 GPM

  • Heads up to 200 feet

  • FM-approved explosion-proof versions

  • Available in wet pit or dry pit installations

  • Integral level control options

Whether you’re outfitting a new pump station or replacing an older grinder pump, the GRP Series provides dependable performance that reduces the likelihood of clogging and cuts maintenance frequency.

Built-In Cutter System: The Core of the GRP Advantage

The hallmark of the GRP Series is its integrated cutter system, engineered from specially hardened stainless steel components. With a hardness rating of HRC 55, this cutter system ensures consistent shredding of tough materials like:

  • Flushable wipes

  • Paper towels

  • Feminine hygiene products

  • Fabric or rags

  • Soft plastics and food waste

The rotating cutter and stationary cutting plate work together to deliver clean, efficient shearing action. This proprietary design not only reduces the likelihood of jamming but also maintains consistent performance over time, even in applications with high debris content.

Versatility Across Applications

The GRP Series can be used across a wide range of wastewater settings, including:

  • Residential sewage ejector pits

  • Low-pressure sewer systems in rural developments

  • Lift stations in commercial buildings

  • Institutional restrooms (schools, jails, nursing homes)

  • Restaurants, hotels, and food service establishments

In all of these environments, grinder pumps reduce the chance of clogs and keep downstream systems running at peak efficiency.

Flexible Installation and Adapter Compatibility

One of the common challenges in replacing existing grinder pumps is compatibility with existing guide rail or adapter systems. Fortunately, HOMA offers a wide range of adapter brackets and guide rail options, making the GRP Series compatible with most competitor systems. This makes retrofitting simple and cost-effective.

Additionally, the GRP Series can be installed in:

  • Wet wells with guide rail removal systems

  • Freestanding sump pits

  • Wall-mounted or floor-mounted dry pit installations

  • Packaged pump systems for plug-and-play setup

Explosion-Proof Models for Hazardous Locations

For wastewater systems that operate in hazardous environments, such as those with methane or hydrogen sulfide exposure, HOMA offers FM-approved explosion-proof GRP models. These pumps are certified for Class I, Division 1 hazardous areas and include:

  • Epoxy-coated motor housings

  • Sealed cable entries

  • Intrinsically safe sensor circuits

  • Anti-condensation heaters (optional)

These models are ideal for lift stations near landfills, food processing plants, or chemical handling areas.

Efficiency and Motor Options

HOMA GRP pumps are available with a variety of motor configurations to suit different performance needs. Motors are designed to operate at high efficiencies across a wide performance curve, ensuring:

  • Reliable flow at variable operating conditions

  • Reduced energy consumption

  • Lower heat generation for longer motor life

Whether you're moving wastewater over long distances or up steep inclines, HOMA offers a motor size and performance range to get the job done.

Real-World Example: Commercial Plaza in Knoxville, TN

A mixed-use commercial plaza housing restaurants, retail stores, and medical offices was experiencing frequent sewage backups due to solids accumulation in its outdated pumping system. The existing pumps couldn’t handle the influx of grease and debris from food prep areas.

Process & Power assessed the site and installed two GRP Series pumps with 7.5 HP motors and advanced cutter systems. The installation also included level controls, duplex control panels, and remote monitoring capability.

Results:

  • Elimination of weekly maintenance and clogging

  • Improved tenant satisfaction and plumbing reliability

  • Maintenance costs dropped by over 50%

  • Extended pump life expectancy due to optimal sizing and materials
