A Complete Guide to Solids Handling, Dewatering, and Slurry Pumps

---

There are three major types of pumps every operation should understand: solids handling, dewatering, and sand, sludge & slurry pumps. Selecting the correct pump for your application is critical to maintaining efficient fluid management across industries: from municipal wastewater facilities to construction sites and manufacturing plants.

The right pump improves operational efficiency, reduces downtime, lowers maintenance costs, and protects your infrastructure. Each pump type is engineered to solve specific challenges, and understanding their differences helps ensure you choose the best system for your environment.

1. Solids Handling Pumps: Built to Prevent Clogs and Keep Operations Moving

When fluids contain debris, fibrous materials, plastics, or grease, standard pumps can quickly become overwhelmed. Solids-handling pumps, including shredder pumps, are designed to prevent these disruptions by efficiently passing solids through the system.

Advanced impellers and integrated cutting or grinding mechanisms break materials down before they cause blockages. Many shredder pumps feature rugged cast-iron or stainless-steel construction paired with oil-filled motors, ensuring long-term durability in demanding environments.

What Is a Solids Handling Pump?

A solids-handling pump is a non-clog pumping solution capable of transporting liquids containing heavy or irregular solids. Available in configurations up to 30 horsepower, these pumps minimize downtime, reduce maintenance requirements, and eliminate the need for manual debris removal.

What Can They Process?

• “Flushable” wipes, and other debris in municipal wastewater
• Plastics
• Food waste
• Fibrous materials
• Solids up to 3.5 inches

Key Benefits

• Prevent costly clogs and service interruptions
• Reduce maintenance and labor
• Improve system reliability
• Handle demanding wastewater applications with ease
• Solids remain large enough to be screened out at the municipal wastewater treatment facility

Common Applications

Solids handling pumps are trusted across commercial, municipal, and industrial settings, including:

2. Dewatering Pumps: Reliable Removal of Unwanted Water

Standing water can delay projects, damage property, and create safety risks. Dewatering pumps quickly remove unwanted water from areas such as basements, tunnels, construction sites, and mines.

As part of the centrifugal pump family, dewatering pumps generate suction that draws water into the system and safely redirects it away from the site.

What Is a Dewatering Pump?

A dewatering pump is designed to remove excess water. Submersible models operate fully underwater, enabling reliable performance even in rugged or hazardous environments.

Advantages and Key Features

• Compact, portable, and durable
• Horsepower ranges from 0.5 to 75 HP
• Flow rates up to 4,000 GPM
• Vertical discharge for narrow basins
• Horizontal discharge for easier maintenance

Recommended Product:

JX Series – Corrosion-Resistant Dewatering Pump

The JX Series by BJM Pumps is built for durability in demanding environments and features cast 316 stainless steel construction with no welds for superior corrosion resistance.

Key Features:

• FKM elastomers (EPDM or Buna optional)
• Double mechanical seal with separate lip seal
• Optional Seal Minder® system
• Built-in thermal protection
• Solids capability up to 3/8”
• High flow up to 650 GPM
• Class F or H motor insulation
• Side discharge
• 0.5HP – 30HP

When to Choose a Dewatering Pump

Selecting the best dewatering solution depends on several factors:

• Hydraulic demands (flow and TDH)
• Presence of solids or chemicals in the effluent (pump materials of construction)
• Excavation depth
• Project scale

While installation can be more complex than above-ground pumps, the reliability and performance gains of submersible pumps often outweigh the upfront investment, especially in flood-prone environments.

3. Sand, Sludge & Slurry Pumps: Engineered for Abrasive Materials

When your operation involves abrasive mixtures, standard pumps simply won’t last. Slurry pumps are purpose-built to move liquids containing abrasive solids such as sand, sludge, coal, or ash while resisting heavy wear.

With primary wear components made of high-chrome iron, these pumps deliver consistent performance in the toughest environments.

What Is Slurry?

A slurry is a mixture of insoluble solid particles suspended in liquid, typically water, to enable efficient transport. Because particle sizes can range from extremely fine to several millimeters, specialized pump construction is required to prevent premature failure.

Key Features and Benefits:

• Handles abrasive solids with minimal wear
• Designed for high-solid concentrations
• Built with heavy-duty materials
• Some models tolerate fluid temperatures up to 200°F

Recommended Product:

KZN Series – Heavy Duty, Abrasion-Resistant Slurry Pump

The KZN Series by BJM Pumps is engineered for demanding sand, sludge, and slurry applications requiring durability and high performance.

Key Features:

• Heavy-duty high-chrome agitator

• 5HP – 30HP

How to Choose a Slurry Pump:

Choose a slurry pump when handling fluids with abrasive solids. These pumps are ideal for dredging, mining, and industrial processes where durability and wear resistance are essential for long-term reliability.
