Submersible Agitator Slurry Pump — Settled Solids Agitation & Slurry Pumping
Heavy-duty submersible agitator slurry pumps for re-suspending settled solids, slurry pumping, and tank desludging. Available from 2 HP to 15 HP with agitator impeller. Trusted across India since 2002.
Quick Answer: What Is an Agitator Slurry Pump?
A submersible agitator slurry pump (also called a slurry agitator or pump with agitator) is a heavy-duty submersible pump with an integrated agitator impeller mounted beside the main impeller. The agitator stirs settled sediment, silt and solids at the tank bottom back into suspension before pumping, so the slurry leaves the tank at consistent density instead of clogging the intake. Flow Chem agitator slurry pumps handle concentrations up to 40% solids by weight, 2-15 HP, flows up to 100 m³/hr and solids to 60 mm — built in an ISO 9001:2015 Gujarat works and supplied across India since 2002.

About Submersible Agitator Slurry Pumps
Flow Chem submersible agitator slurry pumps are purpose-built for re-suspending settled solids and pumping heavy slurry in industrial and municipal applications. Designed and manufactured at our ISO 9001:2015 certified facility in Gujarat.
The integrated agitator impeller stirs settled solids into suspension before the pump impeller draws them in — preventing clogging and ensuring consistent slurry density in the discharge. This makes them ideal for sewage treatment plants, ETP tanks, and industrial sumps where solids accumulate at the bottom.
Available from 2 HP to 15 HP with cast iron construction, double mechanical seals, and agitator impeller as standard. Flow Chem agitator pumps handle slurry concentrations that would clog conventional submersible pumps.
Key Features
Engineered for heavy slurry handling with integrated agitation system
Integrated agitator impeller stirs settled solids into suspension before the pump draws them in. Prevents accumulation at the tank bottom and ensures consistent slurry density in the discharge line.
Double mechanical seals with oil chamber protect the motor from abrasive slurry ingress. Each seal assembly is pressure-tested before dispatch for reliable performance in demanding conditions.
Premium-grade cast iron pump casing, impeller, and agitator for maximum durability in abrasive slurry environments. Hardened wear plate extends service life with minimal maintenance.
Open impeller with wide clearances handles high-concentration slurry without clogging. Combined agitation and pumping action prevents solids from accumulating around the pump intake.
Class F insulation motors rated for continuous duty in demanding slurry applications. Over-sized motor design handles the additional torque load from the agitator impeller.
Compatible with guide rail auto-coupling systems for easy installation and removal without entering the sump. Reduces maintenance downtime and improves operator safety in deep tanks.
Slurry, Sediment and Settled Solids: Terms Explained
Spec sheets and tenders use these terms interchangeably — here is what each one means for pump selection
| Term | What it means |
|---|---|
| Slurry | A liquid carrying suspended solids — sediment, silt, sand, ash or process solids. Specified by concentration (% solids by weight) and particle size, not just flow and head. |
| Slurry agitator / agitator for slurry | The stirring device that re-suspends settled solids so the pump can move them. In these pumps it is built into the unit — no separate tank agitator or manual desludging needed. |
| Sediment & silt | Fine solids that settle and compact at the bottom of sumps, tanks and ponds. Compacted sediment is what blocks a standard submersible pump intake — the agitator loosens it first. |
| Tailings & mine slurry | Leftover mineral solids from ore processing, pumped from sumps and ponds. A core mining application — see our slurry pump selection guide for mining. |
| Fly ash, lime & gypsum slurries | Fine mineral slurries from power, chemical and cement duties (ceramics and cement is a standard Flow Chem application). Fine particles settle fast — agitation before pumping is what keeps lines moving. |
| Desludging & dredging | Pumped removal of settled solids from tanks, sumps and ponds. STP desludging and ETP sludge handling are the two most common Flow Chem agitator duties. |
Whether the duty is a mine sump, an STP desludging point or a construction dewatering pit, the selection logic is the same: match concentration, particle size and flow first. The mines dewatering guide covers the wider pumping system around the slurry duty, and our wastewater pump maintenance schedule shows how to keep seals and oil chambers healthy in slurry service.

Frequently Asked Questions
What is an agitator slurry pump?
An agitator slurry pump is a submersible pump with an integrated agitator impeller that stirs settled solids into suspension before pumping. This prevents clogging and ensures consistent slurry density in the discharge line.
What is the maximum slurry concentration a Flow Chem agitator pump can handle?
Flow Chem agitator slurry pumps can handle slurry concentrations up to 40% by weight, depending on the specific model and solid characteristics. Contact our engineering team for application-specific recommendations.
How does the agitator impeller work?
The agitator impeller is mounted below the pump impeller on the same shaft. As the motor runs, the agitator creates a stirring action at the tank bottom, re-suspending settled solids into the liquid so the pump can draw them in consistently.
Can the agitator pump run dry?
No, agitator pumps should not run dry. The pump requires minimum submersion for both cooling and seal lubrication. Dry running can damage the mechanical seals and motor. Thermal overload protection is included as standard.
Do you provide installation services for agitator pumps?
Yes, Flow Chem provides professional agitator pump installation services across India. Our team handles site assessment, tank preparation, pump installation, guide rail fitting, electrical connections, and commissioning.
When does a slurry tank need an agitator pump?
Whenever solids settle and compact between pumping cycles — STP and ETP sludge sumps, mining slurry ponds, construction sumps and process tanks. Signs you need one: the standard pump clogs on startup, discharge gets thinner the longer you pump, or operators must manually desludge the tank bottom. An agitator slurry pump re-suspends the settled layer first, so pumped concentration stays consistent up to 40% solids by weight.
What is driving agitator pump market demand in India?
Municipal STP and industrial ETP construction, mining output and stricter fly-ash and sludge handling rules are the main growth drivers for agitator pumps in India. Flow Chem has manufactured submersible agitator slurry pumps in Gujarat since 2002 and supplies them across India for sewage desludging, mining slurry and chemical plant duties. Ask for a quote with your tank size and slurry concentration.
Can a submersible pump have a built-in agitator?
Yes — that is exactly what this pump is. The agitator impeller is integrated on the same shaft unit below the motor, stirring settled solids into suspension as the pump runs. It replaces the older approach of a separate tank agitator plus a standard submersible pump, cutting one motor, one set of controls and one maintenance item from the installation.
