The EU expert panel did not identify an immediate health concern linked to TiO2 when used as a food additive. However, due mainly to uncertainties concerning the safety of TiO2 nanoparticles, the panel concluded that TiO2 as a food additive (E171) could no longer be considered safe.
Titanium dioxide is used a food colour (E171) and, as with all food colours, its technological function is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is also present in cosmetics, paints, and medicines.

The vertical design of slurry pumps offers numerous advantages for deep pit applications, from a compact footprint and ease of installation to enhanced durability and simplified maintenance. Vertical multistage centrifugal pumps are particularly well-suited to these environments, where space constraints, high pressures, and abrasive conditions are common. By focusing on structural engineering and optimizing the design of these pumps, industries can ensure reliable performance and cost-effective operation in even the most challenging deep pit applications.
Function: The backplate provides structural support and helps in mounting the pump.
Function: Bearing assemblies support the pump shaft and ensure smooth operation.
- Type of Slurry: Determine if the slurry is abrasive, corrosive, or contains large particles.
The effectiveness of slurry transport using centrifugal pumps largely depends on the pump’s ability to handle abrasive and viscous materials. Performance testing for slurry transport applications involves assessing how well the horizontal centrifugal slurry pump can move slurry without significant wear or loss of efficiency. This testing includes monitoring the pump’s performance over time, particularly under harsh operating conditions, to ensure that the centrifugal slurry pump can withstand the rigors of slurry transport. Evaluating the pump’s performance in this context helps identify potential issues before they lead to system failures, ensuring that the AH Slurry Pump parts remain in good condition and continue to operate efficiently.
Another aspect to consider is the volute's performance under varying operational conditions. Centrifugal pumps are often designed to handle specific flow rates and pressures. When the operational conditions stray from those design limits, the volute may not perform optimally, leading to efficiency losses. Engineers often employ computational fluid dynamics (CFD) simulations to analyze and optimize volute designs based on anticipated operational scenarios.
5. Seals
These flanges serve as the connection points for the inlet and outlet of the pump. Proper alignment and sealing of these flanges are vital to ensure the efficient operation of the pump and to prevent leaks. They can vary in size and shape depending on the specific application and the system's design.
In the demanding environments of mining and quarry operations, the role of horizontal slurry pumps is crucial. These pumps handle abrasive and dense slurries, making them indispensable for processes such as ore transport, tailings management, and sand separation. This article explores how the centrifugal slurry pump design and OEM horizontal slurry pump applications contribute to improved operational efficiency and reduced costs in mining and quarrying.
b. Operating Conditions:
- Temperature: Note the operating temperature of the slurry.
- Most slurry pump manufacturers provide selection charts that correlate slurry characteristics and operating conditions with suitable pump models.
The centrifugal slurry pump design plays a significant role in the effective transportation of slurry in mining operations. The design ensures that the pump can handle high-density materials without compromising performance. This is particularly important in mining, where the slurry often contains heavy and abrasive particles that can wear down pump components. The robust construction and optimized design of horizontal slurry pumps allow them to move large volumes of slurry over long distances, ensuring that materials are efficiently transported from extraction sites to processing facilities. By selecting the appropriate centrifugal pump for slurry, mining operations can maintain consistent material flow, reduce downtime, and enhance overall productivity.
4. Check Pump Performance Curves
1. Impeller
Selecting the right type of impeller is essential for the pump's performance. For instance, if a pump is expected to handle a high volume of sewage containing large solids, an open impeller would be more effective. Conversely, if the pump is mainly handling gray water with minimal solids, a semi-open or enclosed impeller would suffice.
The head, or the height to which a pump can raise the slurry, is another vital performance indicator for horizontal centrifugal slurry pumps. The head is directly related to the pump’s ability to overcome the pressure within the slurry transport system. This metric is typically measured in meters (m) and provides insight into the pump’s power to move slurry through pipelines and other components. The head is crucial for applications involving slurry transport using centrifugal pumps because it determines how efficiently the pump can transport slurry over long distances or through systems with varying elevations. Regular testing of head and pressure ensures that the horizontal centrifugal slurry pump meets the operational demands and maintains system efficiency.
Impellers are the rotating parts of sewage pumps that convert rotational energy from the motor into kinetic energy within the fluid. This transformation occurs through the design of the impeller blades, which are shaped to create a flow of water, pushing it outwards through the volute or the casing. The design of the impeller directly affects the pump's efficiency, capacity, and performance.

Materials: Materials used for shaft sleeves include hardened stainless steel and ceramic-coated materials.
Wear plates are installed within the pump casing to protect the surfaces from the erosive wear caused by the particles in the slurry. These plates can be easily replaced when worn, allowing for maintenance without needing to replace the entire pump. Some wear plates are designed to be adjustable to optimize the pump's performance by fine-tuning the clearance around the impeller.
