Sodium Hydroxide Magnetic Drive Pump Customized Selection Solution

 

In the chemical production field, the transportation of highly corrosive media has always been a core challenge concerning production safety and efficiency. Recently, we received an inquiry from a client whose production process involves the transportation of two media: a 20% concentration sodium hydroxide solution and water. The client had specific and stringent requirements regarding flow rate, pressure, installation method, and explosion-proof performance. Leveraging our professional technical team and extensive industry experience, CIXIFM tailored a customized magnetic drive pump selection solution for the client, successfully solving the transportation challenge.

 

I. In-depth Analysis of the Client's Operating Conditions: Dual Media, Diverse Needs

 

The client's operating conditions exhibited a clear duality, with significant differences in the characteristics and transportation parameters of the two media, posing diverse challenges to the pump equipment's performance.

 

(I) Sodium Hydroxide Solution Transportation: Precise Control in Corrosive Environments

 

The sodium hydroxide solution to be transported by the client was 20% concentration, free of particles, and at room temperature. Regarding flow rate, the maximum demand is 110 kg/h, with a commonly used flow rate maintained at 40-50 kg/h, and a minimum as low as 20 kg/h. The outlet backup pressure requirement is stable at 5-7 kg/h, and can be flexibly adjusted according to production capacity. For piping configuration, the inlet pipe is DN25, and the outlet pipe is DN15. Furthermore, due to potential safety risks in the production environment, an explosion-proof variable frequency motor must be installed.

 

Sodium hydroxide solution is highly corrosive, placing extremely high demands on the corrosion resistance of the pump material. Simultaneously, the wide range of adjustable flow and pressure requirements means that the pump equipment needs precise control capabilities to adapt to changes in conveying capacity.

 

(II) Water Medium Conveying: A Dual Test of High Flow Rate and Specific Installation

 

The commonly used flow rate for water medium conveying is 800 kg/h, with a maximum of 1300 L/h. The outlet backup pressure requirement is also within the 5-7 kg/h range. Vertical installation is explicitly required, and the motor must be equipped with an explosion-proof variable frequency motor. The operating environment is normal temperature.

 

The high flow rate demand for water poses a significant challenge to pump delivery capacity, while the requirement for vertical installation imposes specific constraints on pump structural design. The configuration of an explosion-proof variable frequency motor reflects both a focus on production safety and the customer's need for energy conservation and emission reduction.

 

II. Customized Selection: Two Pump Models for Precise Matching

 

To address the customer's complex operating conditions, the CIXIFM technical team, through rigorous parameter calculations, material comparisons, and performance simulations, recommended two magnetic drive pump products, each suited to the delivery needs of two different media.

 

(I) 1.8CC-72 Magnetic Drive Pump with 0.37KW Explosion-Proof Variable Frequency Motor (Four-Stage): A Guardian of Safety for Corrosive Media

 

This magnetic drive pump is specifically designed for the delivery of sodium hydroxide solutions, perfectly matching its operating characteristics:

 

Precise Flow and Pressure Matching: The pump's flow range fully covers the customer's needs of 20-110 kg/h, operates stably at commonly used flow rates of 40-50 kg/h, and the outlet backup pressure can be precisely controlled at 5-7 kg, flexibly responding to pressure changes caused by capacity adjustments.

 

Corrosion-resistant materials provide robust protection: For 20% sodium hydroxide solutions, the pump body is made of high-quality corrosion-resistant materials, effectively resisting media corrosion and ensuring long-term stable operation without leakage risk.

 

Dual advantages of explosion-proof and variable frequency: Equipped with a 0.37KW explosion-proof variable frequency motor (four-pole), it not only meets explosion-proof safety standards but also allows for precise flow control through frequency conversion, achieving energy-saving operation and reducing production costs.

 

Seamless pipeline connection: The DN25 inlet and DN15 outlet pipe interface design perfectly matches the customer's existing pipeline system, requiring no additional modifications and saving installation costs and time.

 

(II) 18CC-128 Magnetic Pump with 1.5KW Explosion-proof Variable Frequency Motor (Two-pole): The High-Efficiency Choice for High-Flow Transportation

 

For the high-flow transportation needs of water media, this magnetic pump demonstrates powerful performance advantages:

 

Stable output of high flow: The pump's maximum flow rate can easily meet the customer's peak demand of 1300L/h, and it operates efficiently at the commonly used flow rate of 800kg/h. The outlet backup pressure is stably maintained at 5-7 kg, ensuring smooth transportation of water media.

 

Explosion-proof Variable Frequency Energy Saving: The 1.5KW explosion-proof variable frequency motor (two-stage) boasts excellent explosion-proof performance. Simultaneously, the variable frequency function allows for flexible power adjustment based on actual flow requirements, avoiding unnecessary energy consumption and achieving energy saving.

 

Installation Instructions and Alternative Solutions: It should be noted that this pump is designed for horizontal installation and cannot meet the vertical installation requirements for water media transportation. If the customer cannot adjust the installation method, the CIXIFM technical team can provide alternative solutions based on the actual situation to ensure that transportation needs are met.
