Slurry pumps serve as the core equipment in many demanding industrial applications such as mine tailings disposal, river dredging, and municipal flood control. It is facing big challenge when transport abrasive and corrosive mixtures. Because these environments often involve high wear, high solids concentration, and strong chemical corrosion.

With increasing demands for mobility, automation, and environmental adaptability, hydraulic-driven slurry pumps have emerged as the preferred choice across many sectors. Changsha Zhongda Intelligent Equipment Co., Ltd., as a China leading slurry pump manufacturer, leveraging its strong R&D foundation and rich technical expertise, has developed a series of high-performance hydraulic slurry pumps that deliver outstanding performance even under the most demanding operating conditions.

What is a ZONDAR Slurry Pump?

Changsha ZONDAR (or ZONDAR) develops a high-performance series of hydraulic slurry pumps that specifically designed to move mixtures of liquid and solid particles and excel under complex working conditions. As a high-tech enterprise specializing in hydraulic transmission and intelligent equipment, ZONDAR offers a full range of solutions, including hydraulic slurry pumps, hydraulic submersible pumps, and hydraulic drainage robots, which are widely used in tailings transfer, lake restoration, emergency dewatering, and more.

Where are slurry pumps used?

Slurry pumps are widely used in:

• Mining :transporting ore slurry, tailings
• Dredging operations: river/lakebed excavation
• Construction: concrete pumping with aggregates
• Chemical and industrial processes involving abrasive or corrosive liquids
• Municipal projects like flood control and wastewater treatment

How Zondar Slurry pump work?

ZONDAR slurry pumps use hydraulic power instead of electricity, making them ideal for remote or harsh environments like mining and dredging. A hydraulic power pack drives the pump’s motor, which spins the impeller to create suction and discharge slurry through centrifugal force.

Key Advantages：

High-concentration handling: Capable of transporting slurries with up to 80mm solids.

Exceptional adaptability: Operates without external power supply—ideal for off-grid, rugged environments.

Smart control systems: Supports remote start/stop, real-time parameter monitoring, and special working conditions that people can not reach.

Wear-resistant construction: Pump bodies and impellers are made from custom-cast wear-resistant alloys.

ZONDAR Hydraulic Slurry Pumps: Dual Protection Against Wear and Corrosion

ZONDAR slurry pump impellers are integrally cast and undergo multiple heat treatment processes to significantly enhance wear resistance. For corrosive working conditions, customized impellers made from special stainless steel materials are also available to meet diverse customer needs. Compared to standard stainless steel, ZONDAR’s hydraulic slurry pumps offer superior overall performance and are fully suitable for marine environments, delivering greater adaptability across challenging applications.

Key Considerations When Selecting a Hydraulic Submersible Slurry Pump

Proper pump selection is essential for ensuring long-term, stable operation. Hydraulic slurry pumps involve complex integrations of hydraulic systems, electronic controls, and mechanical structure. Key considerations include:

1. Operating Environment

Clear water: Standard models are suitable.

Sewage: Requires wear-resistant impellers.

Seawater: Impeller and casing must be corrosion- and wear-resistant.

Required head and flow rate: Determines the pump model and hydraulic system specifications.

2. Hydraulic System Compatibility

Power source: Ensure the hydraulic station provides sufficient pressure and flow.

Cooling & protection: For heavy-duty use, check whether the system includes self-cooling or oil temperature protection.

Drive type: Determine if the system is diesel-powered and whether it supports multi-device linkage.

3. Ambient Temperature：Designed to operate between -15°C and +50°C. Custom solutions are available for extreme weather conditions.

4. Flow Rate Matching：Hydraulic submersible pumps require a separate hydraulic power station. The pump’s flow input must match the output of the power station to ensure stable operation.

ZONDAR offers a range of models to suit different working conditions:

Model	Flow/（㎥/h）	Max Head/m	Hydraulic Flow/Lpm	Outlet /mm	Max Particle Size /mm
DZTP-02	50	30	20-30	50	25
DZTP-03	100	25	26-34	75	25
DZTP-04	200	25	30-40	100	25

Case Study: 2024 Emergency Dewatering Project in Hunan Province
During a municipal flood emergency in 2024, ZONDAR’s portable hydraulic slurry pump was deployed for rapid drainage. Its quick setup and high-efficiency pumping significantly reduced emergency response time.

User Feedback：End users have reported that ZONDAR hydraulic slurry pumps offer stable performance, long continuous runtime, easy maintenance, and strong environmental adaptability—making them particularly suitable for remote, power-deficient, or complex site conditions.

Can Zondar Slurry pump pump Sand or mud?

Zondar slurry pumps are designed to handle abrasive and high-density mixtures under 25% like sand, mud, and other solids-laden fluids. Their wear-resistant materials and robust design allow them to efficiently transport such abrasive slurries without rapid wear or clogging.

What is the difference between a sludge pump and a slurry pump?

Slurry Pump: Primarily designed to move mixtures of water and solid particles (like sand, ore, or tailings) with relatively high flow rates and moderate solid concentrations. Slurry pumps usually handle higher velocities and are used in mining, dredging, and industrial processes.

Sludge Pump: Typically meant for thicker, more viscous materials with a higher concentration of organic or semi-solid waste (like sewage sludge or industrial waste). Sludge pumps often focus more on handling fibrous or sticky materials and may have different impeller designs to prevent clogging.

What is the difference between a water pump and a slurry pump?

Water Pump: Designed for clean or slightly dirty water, focusing on moving low-viscosity, low-solid fluids efficiently. Typically not built to handle abrasive solids.

Slurry Pump: Specifically engineered to transport abrasive, solid-laden fluids with high wear resistance and robust materials to prevent rapid damage.

What is the difference between a sewage pump and a slurry pump?

Sewage Pump: Built to handle wastewater containing solids like human waste, paper, and organic matter; often equipped with grinders or cutters to prevent clogging.

Slurry Pump: Focused on pumping abrasive mixtures of water and mineral solids like sand, gravel, or ore particles, usually with higher abrasion resistance but less emphasis on grinding capabilities.

Conclusion

As a heavy-duty essential in demanding working conditions, hydraulic slurry pumps rely on the precise integration of materials, structural design, and power systems to perform effectively. Zondar’s hydraulic slurry pumps deliver a comprehensive solution through advanced material selection, smart features, and outstanding adaptability—earning the trust of users across diverse industries.
