Case Study on Reducing Energy Consumption of Slurry Pump

---

• TIME : 2025-12-12

Through comprehensive measures such as rational selection, variable frequency speed regulation, material upgrading, and system optimization, the energy consumption of slurry pumps can be significantly reduced by more than 30%, and the energy-saving rate of some high-efficiency renovation projects can even exceed 20%.

Slurry pumps are widely used in industries such as mining, metallurgy, power, and sewage treatment. Due to the high concentration of solid particles in the conveying medium, there are common problems such as low efficiency (usually 55% -75%), high energy consumption, and fast wear during operation. With the trend of green and low-carbon development, enterprises are carrying out energy-saving renovations to reduce operating costs and enhance sustainability.

In recent years, multiple industries have successfully implemented energy-saving and consumption reducing projects for slurry pumps, covering equipment replacement, process optimization, intelligent control, and other aspects, achieving considerable economic and environmental benefits.

Summary of core energy-saving strategies

Accurate selection and matching: Select the pump type based on actual flow and head requirements to avoid energy waste caused by high head or mismatched motor power.

Adopting frequency conversion speed regulation technology: By adjusting the pump speed through a frequency converter, the pump always operates in the high-efficiency zone, adapts to changes in working conditions, and achieves on-demand energy supply.

Upgrade wear-resistant materials: Use new wear-resistant components such as silicon carbide ceramics, high chromium alloys, and ceramic composite materials to extend their lifespan and reduce maintenance downtime and replacement energy consumption.

Optimize pipeline system: reduce the number of elbows and valves, lower resistance losses along the way, and improve overall conveying efficiency.

Intelligent control: Integrating sensors and IoT platforms to achieve remote monitoring, fault warning, and adaptive adjustment, improving operational stability and energy efficiency.

suggestion

When promoting energy-saving renovation of slurry pumps, enterprises should prioritize energy efficiency evaluation and choose a suitable renovation path based on their own working conditions:

Consider replacing the old pump station with an efficient and energy-saving pump as a whole;

Prioritize introducing variable frequency control in scenarios with large load fluctuations;

It is recommended to use ceramic composite pumps in environments with strong wear and tear;

Establish a regular maintenance system to maintain the optimal clearance and sealing performance of the impeller.
