JUSH supplies six horizontal slurry, gravel and mortar pump series for transporting abrasive, corrosive and solids-containing fluids. The current range includes AH, ZJ and ZD/G horizontal slurry pumps, G/GH gravel pumps, UHB-ZK corrosion-resistant mortar pumps and MIP fluorine-lined slurry pumps.
The product range covers mining slurry, tailings, mineral concentrate, sand, gravel, ash, industrial sludge and corrosive slurry transfer. Each pump is specified according to flow rate, total head, slurry density, solids concentration, particle size distribution, pH, temperature and installation conditions.

|---|---|---|
| AH Type | Single-stage, single-suction, cantilever, double-casing horizontal centrifugal slurry pump | Mining, coal, metallurgy, power generation and building-material processing |
| ZJ Type | Horizontal slurry pump | Abrasive slurry transfer |
| ZD/G Type | Horizontal slurry pump | Industrial slurry transport |
| G/GH Type | Single-stage, single-suction, cantilever horizontal gravel pump with a single casing | Dredging, sand handling, mining slurry and metallurgical slag |
| UHB-ZK Type | Single-stage, single-suction centrifugal mortar pump with UHMWPE pump-body construction | Corrosive liquids and slurry containing solid particles |
| MIP Type | Plastic-lined and fluorine-lined slurry pump | Corrosive slurry transfer |
Each product page contains the model-specific performance table and construction information. The final duty point is based on slurry conditions rather than clear-water flow and head alone.
A centrifugal slurry pump uses a rotating impeller to transfer mechanical energy to a mixture of liquid and suspended solids. The impeller accelerates the slurry, while the pump casing converts part of the velocity into pressure and directs the flow toward the discharge connection.
Slurry duty differs from clean-water duty because suspended solids affect density, hydraulic losses, wear rate and required shaft power. Particle size, particle shape, hardness, solids concentration and slurry chemistry also influence the wet-end material and impeller configuration.
For settling slurry, the pipeline velocity remains above the critical deposition velocity throughout the operating range. Metso’s slurry-pump engineering handbook also identifies flow, head, solids density, slurry concentration, maximum particle size, average particle size, pH and chemical composition as core sizing data.Metso Slurry Pump Basic Handbook
The AH series is a single-stage, single-suction, cantilever, double-casing horizontal centrifugal slurry pump. Its published construction includes:
Ductile-iron pump casing and cover
High-chromium wear-resistant alloy or rubber flow-passage components
Wide impeller passages
Front and rear impeller auxiliary vanes
Packing, expeller or mechanical shaft-seal arrangements
Discharge positions arranged at 45-degree intervals
Grease-lubricated or oil-lubricated bearing arrangements
The AH product page positions this series for abrasive and high-concentration slurry in mining, coal, metallurgy, power generation and building-material processing.
The G/GH series is a single-stage, single-suction, cantilever horizontal centrifugal gravel pump with a single pump casing. Its published design includes a wide flow passage and a discharge direction that can be installed through 360 degrees.
The series is used for:
Dredger slurry transfer
Sand dredging
Abrasive sand and mud
Mining slurry
Metallurgical slag
Large solids requiring a wider passage
The published G/GH table includes 6/4D-G, 8/6E-G, 10/8F-G and 10/8S-G models. The displayed performance data covers multiple rotational speeds and operating points rather than one fixed capacity for each model.
The UHB-ZK is a single-stage, single-suction centrifugal mortar pump developed for media combining corrosion and abrasion. The product page identifies ultra-high-molecular-weight polyethylene, or UHMWPE, as the pump-body material.
The published construction also includes:
Rear pull-out arrangement
Mechanical shaft seal
Corrosion-resistant flow path
Wear-resistant wetted structure
Operation with particle-containing acidic, alkaline and wastewater media
The current product page contains an incomplete temperature statement and does not publish a complete maximum operating-temperature range. The classification page therefore does not state an unsupported temperature limit.
The MIP is the plastic-lined and fluorine-lined product in the current slurry pump category. Its category positioning is corrosive slurry transfer where the complete wetted-material configuration is compatible with the liquid and suspended solids.
Fluorine lining does not give one universal chemical or temperature rating. The operating envelope is controlled by the complete lining material, backing structure, shaft seal, particle characteristics, liquid concentration and temperature.
The ZJ and ZD/G products are horizontal slurry-pump series within the current JUSH range. Their individual pages retain the model-specific performance data, dimensions and hydraulic operating points.
The ZD/G series also has direct Google visibility for the query “slurry zd/g type horizontal slurry pump.” The category page links to the ZD/G product using that complete descriptive anchor text.
The AH product page states that its flow-passage components are available in high-chromium wear-resistant alloy or rubber. Metal and rubber wet-end components serve different particle, impact, corrosion and wear conditions.
Material assignment is based on:
Maximum particle size
Particle-size distribution
Particle shape and hardness
Slurry density
Solids concentration by weight and volume
Slurry temperature
pH and chemical composition
Impeller speed
Required service interval
These factors are also identified in established slurry-pump selection guidance from Metso and Weir.Metso handbook Weir particle-size guidance
The UHB-ZK product page identifies UHMWPE as its pump-body material. This distinguishes the series from the metal and rubber wet-end construction published for the AH series.
The UHB-ZK is presented for combined corrosion and abrasion duties involving particle-containing liquids, mortar and industrial wastewater.
The MIP series provides the fluorine-lined construction in the current product range. Its material positioning is kept separate from the AH and UHB-ZK series because the three designs use different wetted structures.
The six current JUSH series cover these published application groups:
Mining slurry transfer
Mineral concentrate transport
Tailings transfer
Coal slurry handling
Sand and gravel transport
Metallurgical slag transfer
Power-plant ash slurry
Chemical slurry
Industrial wastewater containing particles
Industrial sludge transfer
Dredging and sand extraction
Building-material processing
Each application is assigned to a product series through the actual slurry and hydraulic data.
A complete slurry-pump enquiry contains:
Required slurry flow in m³/h
Required solids throughput in tonnes per hour
Static head
Pipeline length and internal diameter
Pipe fittings and equipment pressure losses
Slurry density
Carrier-liquid density
Solids density
Solids concentration by weight
Solids concentration by volume
Maximum particle size
Particle-size distribution, including d50
Particle shape and hardness
Slurry pH
Chloride and chemical content
Operating temperature
Viscosity or yield stress
Suction pressure and available NPSH
Installation altitude
Continuous or intermittent operation
Motor voltage, frequency and phase
Slurry concentration by weight and slurry concentration by volume are not interchangeable. A centrifugal pump is sized by volumetric flow, so solids tonnage and concentration data are converted into the actual slurry flow and density before the hydraulic duty point is established.
The pump operates close to the selected hydraulic duty point. Operation far below or above the intended range increases recirculation, vibration and component wear.
The installation follows these requirements:
Suction piping remains short and direct.
Pump suction is continuously supplied with slurry.
Air pockets are removed from the suction arrangement.
Available NPSH remains above required NPSH.
Pipeline velocity remains above deposition velocity for settling slurry.
Piping loads are not transferred to pump flanges.
Bearings receive the specified lubricant.
Seal-water pressure and flow match the installed shaft-seal arrangement.
The pump is not operated continuously against a closed discharge valve.
Rotation direction is checked before slurry enters the pump.
Motor current, bearing temperature, vibration and discharge pressure are recorded during operation.
Slurry pumps are inspected according to operating hours and measured wear rather than after complete performance loss.
Routine inspection includes:
Impeller leading edges and vane thickness
Front and rear liners
Volute or casing wear
Impeller-to-liner clearance
Shaft sleeve
Packing, expeller or mechanical seal
Bearing temperature and lubrication
Shaft vibration
Coupling alignment
Fasteners and foundation
Suction and discharge pressure
Motor current
Flow-rate reduction
Changes in particle size or solids concentration
Wear components are replaced before casing integrity, hydraulic stability or shaft alignment is affected. Each inspection record includes pump model, serial number, slurry composition, operating hours, measured clearances and replaced parts.
A slurry pump is designed to transport a mixture of liquid and suspended solid particles. Its hydraulic passages, impeller, casing and wear materials are configured for erosion, solids passage and the density of the pumped mixture.
The G/GH horizontal gravel pump is the current JUSH series designed with a wide passage for abrasive sand, mud, gravel and larger solids.
The UHB-ZK corrosion-resistant and wear-resistant mortar pump uses an UHMWPE pump-body construction.
The AH series product page specifies high-chromium wear-resistant alloy or rubber flow-passage components. Metal and rubber wet-end components can be configured according to the operating conditions.
Flow, total head, slurry density, solids density, solids concentration, maximum particle size, particle-size distribution, pH, temperature, viscosity and available NPSH control pump sizing and material selection.
Suspended solids change slurry density, hydraulic losses, required shaft power and wear. The published clear-water curve is corrected using the actual slurry properties and system resistance.
No. The hydraulic model, impeller passage, wet-end material and shaft seal are matched to the specific particles, concentration, chemistry and operating conditions.
