Hippo Slurry Pumps
The design of Hippo Slurry Pumps prioritises durability, wear resistance, and controlled solids handling.
Heavy-duty submersible slurry pumps engineered for continuous operation in abrasive, solids-laden environments, delivering controlled performance, reliability, and extended service life in demanding mining and mineral processing applications.

Heavy Duty Slurry Pumps for Mining and Industrial Applications
Heavy duty slurry pumps are engineered to handle abrasive, high-solids, and high-density slurries in some of the most demanding industrial environments. These pumps play a critical role in maintaining uptime across mining, mineral processing, and heavy industrial operations where process interruptions carry significant operational and financial risk.

What Is a Heavy Duty Slurry Pump?
A heavy duty slurry pump is a centrifugal pump specifically designed to transport slurries containing abrasive solids, coarse particles, and corrosive media. Unlike standard centrifugal pumps, slurry pumps are built with:
-
Reinforced casings
-
Heavy-wall wear components
-
Hardened or elastomer-lined internals
-
Shaft and bearing assemblies designed for high radial loads
These features allow the pump to operate reliably under high wear, high impact, and variable flow conditions.
Typical Applications for Heavy Duty Slurry Pumps
PCS heavy duty slurry pumps are commonly specified for:
-
Mining slurry transfer
-
Tailings handling
-
Mineral processing circuits
-
Thickener underflow
-
Mill discharge and cyclone feed
-
Ash handling in power generation
-
Industrial effluent with suspended solids
Each application presents unique challenges related to particle size, slurry density, abrasiveness, and chemical composition, making correct pump selection essential.

Key Design Features and Performance Benefits
Heavy duty slurry pumps supplied by PCS are selected to deliver long service life and stable hydraulic performance under severe operating conditions.
Core Performance Advantages:
-
High resistance to abrasive wear
-
Stable performance at high solids concentrations
-
Robust bearing assemblies for extended MTBF
-
Replaceable wear components to reduce lifecycle cost
