The Hydroman® TJQ Vertical High Head Slurry Pump represents a breakthrough in robust fluid handling technology, engineered to excel in the most challenging industrial environments. As a vertical, cantilevered centrifugal slurry pump, it combines cutting-edge design with superior performance to handle abrasive, high-density slurries across industries such as metallurgy, mining, coal processing, power generation, construction materials, and environmental protection. With its modular configuration and multi-stage installation capabilities, the TJQ heavy duty gravel pump series delivers unmatched efficiency, durability, and adaptability for modern industrial demands.
1. Vertical Cantilever Configuration
Unlike traditional horizontal pumps, the TJQ’s vertical design optimizes space utilization while minimizing operational vibrations. Its cantilevered structure eliminates the need for shaft seals on the feed side, reducing wear risks in abrasive applications.
2.Multi-Drive Compatibility
• Direct drive (for stable, high-efficiency operation)
• V-belt drive (adjustable speed control)
• Electric coupling drive (soft-start capability)
• Reducer drive (precision torque management)
3. 360° Adjustable Discharge Port
The discharge outlet rotates in 45° increments, enabling 8 installation angles for seamless pipeline integration across complex layouts.
4. Advanced Sealing Systems
• Triple-action packing seals
• Auxiliary impeller pressure balancing
• Double mechanical seal options (for toxic/volatile slurries)
5. Material Engineering Excellence
Critical components like the impeller, casing, and wear plates are cast from Cr27 high-chrome alloy, achieving HRC 58–62 hardness for 3× longer lifespan than standard pumps in high-solids applications.
1. Heavy-Duty High-Pressure Performance
The TJQ vertical submersible slurry pump delivers up to 120m head capacity, outperforming conventional gravel pumps in mining and dredging operations. Its optimized impeller vanes maintain 78% hydraulic efficiency even with slurries containing 65% solids by weight.
2. Submersible High Head Sand Pump Capability
Engineered for submerged installations in sumps or tailing ponds, the TJQ handles:
• Sand-laden fluids (up to 40% particle concentration)
• Sludge with 80,000 cP viscosity
• Gravel mixtures with 50mm particle size
3. Corrosion-Resistant Construction
A proprietary nano-ceramic coating on wetted parts provides:
• 92% resistance to pH 2–14 chemicals
• 85% reduction in chloride-induced pitting
• Compliance with ISO 12944 C5-M corrosion standards
4. Agitator-Enhanced Slurry Handling
Optional integrated agitator (up to 350 RPM) prevents sedimentation in thick liquid pumping scenarios, ensuring continuous flow of:
• Coal washing plant tailings
• Mineral processing concentrates
• Dredged marine sediments
5. Energy-Efficient Operation
The TJQ’s DOE-compliant design reduces power consumption by 18–22% through:
• CFD-optimized casing geometry
• Reduced recirculation losses
• Regenerative cooling system for motors
1. Mining & Mineral Processing

Pre-Installation Checks
• Verify NPSHa > NPSHr by 1.2m minimum
• Align pump within 0.05mm/m tolerance
• Use anti-vibration pads (25mm neoprene recommended)
Optimized Operation
• Maintain 30–45% BEP flow range
• Monitor bearing temperature (<80°C)
• Lubricate every 2,000 hours (NLGI 2 grease)
Troubleshooting Tips
• Low Flow: Check for impeller wear (max 6mm clearance)
• Vibration: Inspect shaft runout (<0.1mm TIR)
• Seal Leakage: Verify flush water pressure (1–2 bar above suction)
Case 1: Copper Mine Dewatering (Chile)
• Challenge: Pumping 1,200m³/day of acidic slurry (pH 3.5) from 150m depth.
• Solution: TJQ with tungsten carbide lining and double mechanical seals.
• Result: 14-month continuous operation with zero unplanned downtime.
Case 2: Municipal Sewage Plant (Germany)
• Challenge: Handling 8% fibrous sludge in digestion tanks.
• Solution: TJQ with vortex impeller and agitator package.
• Result: 60% energy savings vs. progressive cavity pumps.
Q1: Can the TJQ handle abrasive fluids like silica sand?
A: Yes. With CrMo27 alloy components, it withstands 15g/tonne abrasion levels – ideal for frac sand processing.
