A lime slurry pump is a type of industrial pump specifically designed for transporting highly alkaline, high-solids content slurries such as lime slurry, lime milk, and hydrated lime slurry. It is a specialized type of industrial slurry pump. These media are characterized by their tendency to settle, strong abrasiveness, scaling, and significant corrosiveness. Therefore, lime slurry pumps are specifically optimized for lime applications in terms of structural design, wear-resistant and corrosion-resistant materials, and sealing methods.
Process Features
Module title
Specialized Casting: Utilizing automatic resin sand molding and medium-frequency induction furnace melting, the high-chromium alloy composition is precisely controlled, and castings undergo ultrasonic testing to ensure no internal defects.
Enhanced Heat Treatment: Quenching and tempering are performed in a CNC furnace, ensuring a stable surface hardness of HRC 60 or higher while maintaining toughness.
Precision Machining: Core components are machined by five-axis machine tools, guaranteeing precise flow channel profiles and dynamic balance calibration for smooth operation.
Rigorous Testing: From raw material spectral analysis to finished product coordinate measuring, dimensions and performance are controlled throughout the process, and actual working condition hydraulic testing is performed before delivery.
Surface Protection: Flow-through parts can be treated with enhanced coatings such as tungsten carbide spraying, and non-machined surfaces use heavy-duty anti-corrosion coatings to adapt to complex environments.
Application Scenarios
Thermal Power/Steel Plant Flue Gas Desulfurization (FGD) Systems:
Used as absorption tower circulation pumps or limestone slurry supply pumps, they are core power equipment for desulfurization devices.
Chemical and Mining Industries
Transporting various alkaline slurries or chemical media containing solid particles.
Water Treatment and Wastewater Treatment
Used to transport lime milk to adjust pH or for chemical precipitation.

FAQ
Q: What is the maximum solid particle size and concentration that a lime slurry pump can handle?
A: Standard models can handle a maximum particle size of ≤6mm and a solid content (by weight) of ≤65%. For special working conditions (such as larger particles or higher concentrations), a custom-designed wide-channel impeller can be provided.
Q: How can you ensure that the lime slurry pump performs as expected under actual operating conditions?
A: We provide in-depth selection services based on the customer's specific operating conditions (medium analysis, system curves). For critical projects, we can arrange factory witness testing to verify performance by simulating actual operating parameters before shipment. We can also provide data from similar operating cases as a reference.
