Shanglishi Pump Group, Three-Step Selection Method | Improve your slurry pump system efficiency by 30%

The Three-Step Precise Selection Method for Shanglishi:

In industries such as mining, metallurgy, power generation, and dredging, the energy consumption and maintenance costs of slurry pumping systems often serve as “hidden killers” of operational expenses. Choosing the wrong pump not only results in persistently high energy consumption but also leads to production disruptions, frequent repairs, and a dramatic increase in spare parts consumption.

With more than 30 years of deep expertise in the industrial pump sector, Shanglishi Pump Group has witnessed over a thousand successful conveyor system projects. We’ve found that over 60% of on-site issues stem from initial selection errors. To address this, we’ve integrated decades of engineering experience and distilled the following: The “Shanglishi Three-Step Precise Selection Method” systematically addresses the challenges of equipment selection, helping customers achieve a guaranteed improvement in conveying efficiency of more than 30% and a significant reduction in overall operation and maintenance costs.

Step 1: In-depth Operational Condition Diagnosis

Traditional selection methods often stop at a simple match based on “flow rate, head, and medium name”—a practice that’s akin to customizing a racing suit solely according to a person’s height and weight—far from sufficient.

Shanglishi Pump Group adheres to the principle: Precise equipment selection begins with systematic diagnosis.

Our engineering team will conduct an in-depth analysis across three dimensions:

1. Media holographic image analysis

Not only does it measure concentration and average particle size, but it also conducts laboratory analyses to determine particle size distribution, angularity, Mohs hardness, and specific gravity.

Accurately determining the abrasiveness index and settling characteristics of the slurry is fundamental to selecting the appropriate pump type, rotational speed, and material.

2. Real System Resistance Mapping

Analyze using professional software Piping layout, number and type of bends, and inlet/outlet conditions

Accurately depict the real. System Characteristic Curve Avoid having the pump consistently operate in a low-efficiency range due to an “excessively large safety margin.”

3. Operating System and Future Condition Assessment

Analyze continuous operating duration, traffic adjustment requirements, and start-stop frequency.

Assess potential future changes in production processes to ensure that the pump selection is appropriate. Moderate forward-looking approach

The value of this step: Transform vague operational requirements into precise engineering language, laying the foundation for accurate matching.

Step 2: System-wide Collaborative Matching

Based on accurate diagnosis, Shanglishi never offers a single product—it provides instead... A collaborative solution package featuring "pump type + material + seal + drive" 。

Core Match 1: Pump Type and Hydraulic Model

Heavy-duty vs. Light-duty Series: For conditions involving high impact and high abrasion (such as coarse-particle slurries), we employ... Heavy-duty slurry pump Its bearing housing, shaft, and casing are all designed for maximum reliability. For fine particles and low-concentration slurries, the following is selected: High-efficiency lightweight series Achieve optimal energy efficiency while ensuring longevity.

CFD Flow Field Optimization Design: By employing computational fluid dynamics simulations, we pre-optimize the matching between the impeller and the volute, addressing the issue at its root. Reduce eddy currents and localized wear. Expand the high-efficiency zone.

Core Match 2: Materials Science Matrix

Shanglishi Pump Group establishes an industry-leading “ Operating Condition - Material - Life Database, scientifically recommended:

A05 Ultra-high-chromium cast iron: The ultimate choice for resisting strong impacts and coarse particles, combining high hardness with excellent toughness.

Special rubber lining: For fine-particle slurries with no sharp edges or corners, it offers an excellent balance of wear resistance and corrosion resistance.

Composite material solutions: Offer customized protection solutions under extremely demanding conditions where abrasion and corrosion occur simultaneously. Principle: Not judging superiority or inferiority by the initial price, but rather by... Lowest total lifecycle cost To be guided by

Core Match 3: Materials Science Matrix

High-efficiency motor matching: The flow demand automatically adjusts the rotational speed, ensuring that the pump unit always operates within its high-efficiency range—this is the core approach to achieving a 30% energy savings.

Customized sealing solutions From the economically reliable auxiliary impeller + packing seal to achieving zero leakage. Modular Double-End Mechanical Seal Combined with the intelligent flushing system, it thoroughly solves the leakage problem.

Step 3: Full Lifecycle Performance Assurance

Case Study: How a 35% Efficiency Improvement Was Achieved

Project Background A certain customer was originally using four imported slurry pumps, which had an average operating efficiency of only 68%. Annual electricity costs exceeded ten million yuan, and the wear parts needed to be replaced frequently, severely impacting production continuity.

Implementation of the Three-Step Approach by Shanglishi Pump Group:

Deep diagnostics It was discovered that the original pump design had an excessively high head, causing the actual operating point to significantly deviate from the efficient range. At the same time, the content of high-hardness, angular quartz sand in the slurry was severely underestimated.

Collaborative matching ：

Replace with 3 units. High-efficiency heavy-duty slurry pump with upper impeller Re-match the pump model so that the rated high-efficiency point coincides with the actual operating point.

The flow passage components adopt... “A05 Ultra-High Chromium Cast Iron + Wear-Resistant Channel Optimization” Technology.

Install additionally Control system Adapt to traffic fluctuations.

Performance Guarantee Provides full-process supervision services.

Results:

New system The average operating efficiency has jumped to 89%. Annual electricity savings exceed 3 million kilowatt-hours.

Service life of flow components life More than double the duration Annual maintenance costs have decreased by more than 40%.

Overall transportation efficiency improved by more than 35%.

The payback period is less than 16 months.

The selection of slurry pumps is an empirical discipline that integrates fluid mechanics, materials science, and systems engineering. Even a tiny deviation in pump selection can be magnified infinitely over the equipment’s lifespan of up to ten years, continuously eroding the company’s profits.
