Jiangsu Haifa Machinery Manufacturing Co., Ltd.

Product Overview

Pumping media containing solid particles, crystallizing substances, fibers or slurries places demanding requirements on pump design, corrosion resistance and wear resistance. When conventional magnetic drive pumps handle such media, potential challenges include accelerated wear of wetted components, flow passage blockage and particle accumulation in the magnetic coupling area.

Jiangsu Haifa Machinery Manufacturing Co., Ltd. provides magnetic drive pumps and corrosion- and wear-resistant pump solutions. Pump configurations can be evaluated and customized according to the medium composition, solids concentration, particle size, temperature, corrosiveness, required flow rate and head.

The magnetic drive design eliminates the conventional mechanical shaft seal, helping reduce the risk of shaft-seal leakage. Through appropriate impeller selection, flow passage optimization and wetted-material selection, the pump solution can address corrosion, abrasion and operational reliability requirements in demanding chemical processes.

Key Features

1. Magnetic Drive and Seal-Less Construction

The magnetic coupling transmits power without a conventional mechanical shaft seal, helping reduce leakage risk in applications where containment of the process medium is important.

2. Customized Impeller and Flow Passage Design

Impeller configuration and internal flow passages can be evaluated according to particle size, solids concentration, viscosity and crystallization tendency to help reduce particle accumulation, blockage and jamming.

3. Corrosion- and Wear-Resistant Materials

Depending on the medium and operating conditions, potential material options include wear-resistant alloys, hard alloys, silicon carbide, Hastelloy, duplex stainless steel and suitable lining systems. Final material selection is subject to engineering evaluation.

4. Solutions Tailored to Difficult Operating Conditions

Pump structure, wetted components and materials are selected according to the specific medium and operating conditions rather than relying on a single standard configuration for all applications.

5. Technical Support for Industrial Projects

Based on customer process data, technical support may include pump selection recommendations, technical specifications, performance curves and relevant documentation for engineering, procurement and tender submissions.

Typical Applications

• Coal chemical industry: Conveying solid-laden, slag-containing and corrosive process media.

• Salt chemical industry: Handling salt-containing, crystallizing media and crystal-bearing slurries.

• Fine chemical industry: Conveying acids, alkalis and other corrosive media containing particles.

• Pharmaceutical industry: Selected solid-laden process applications, subject to process and material requirements.

• Other industrial applications: Handling media containing fibers, slag or precipitated solids.

Suitability must be evaluated against the actual medium properties and operating conditions.

Technical Parameters and Selection Basis

The pump is selected and configured according to the application. Key selection parameters include:

• Flow rate: Determined by process requirements.

• Head: Determined by system resistance and required process pressure.

• Solids concentration: Based on actual medium data.

• Solid particle size: Based on particle dimensions, hardness and shape.

• Operating temperature: Based on actual process conditions.

• Medium density, viscosity and corrosiveness: Used for hydraulic calculations and material selection.

• Wetted materials: Selected according to corrosion and abrasion requirements.

• Applicable standards: Determined by the product, contract and project specifications.

Final performance parameters are subject to engineering selection and confirmation of the applicable pump performance curve.

Information Required for Pump Selection

To support accurate pump selection, please provide:

1. Medium name and chemical composition.

2. Solids concentration and particle size.

3. Medium temperature, density, viscosity and corrosiveness.

4. Required flow rate and head.

5. Whether the medium tends to crystallize, settle or contain fibers.

6. Continuous or intermittent operating requirements.

7. Installation conditions and applicable technical specifications.

Frequently Asked Questions

Can magnetic drive pumps handle media containing solids?

They can be evaluated for such applications. Suitability depends on solids concentration, particle size and hardness, medium corrosiveness and pump design. Application-specific engineering assessment is required.

How can wear and blockage be reduced?

Potential measures include optimizing the impeller and flow passages, selecting suitable wear-resistant materials and matching the pump design to the particle characteristics. The appropriate solution depends on the actual medium data.

Can a magnetic drive pump handle a high solids concentration?

This requires evaluation of solids concentration, particle dimensions and hardness, and the flow behavior of the medium. Higher solids concentrations or larger particles generally increase design complexity and require detailed technical review.

Can these pumps handle highly corrosive media containing solids?

A suitable solution may be possible. Wetted materials should be selected according to the chemical composition and operating conditions, with material compatibility and operating limits verified before final selection.
