Selection of magnetic drive pump for ether solvents

 

 

Customer Requirement Overview

Today, a customer plans to purchase a magnetic drive pump suitable for transporting ether solvents and has provided the following specific parameters:

 

Medium: Ether solvent (pure and particle free)

Viscosity: 10-20cps (close to aqueous medium)

Flow rate: 5 liters per minute

Temperature: Normal temperature environment

Export pressure: Low pressure demand

Preliminary inquiry from the customer: Is the CX-S-6.0-88 pump equipped with a variable frequency motor suitable?

The customer is preliminarily considering using the CX-S-6.0-88 magnetic drive pump and pairing it with a variable frequency motor. However, after eva luation by technical personnel, this model of pump may not be the best choice for the following reasons:

 

Excess flow: The CX-S-6.0-88 pump is designed with a large flow rate, far exceeding the customer's required 5 liters/minute, which may result in energy waste and low operating efficiency.

Cost considerations: Choosing a pump with a larger model not only increases initial investment, but also increases long-term operating costs (such as energy consumption) accordingly.

Technical team recommended solution: 3.2CC-88 magnetic drive pump+2-stage variable frequency motor

Based on customer needs, technicians recommend the following configurations:

 

Pump type selection: 3.2CC-88 magnetic drive pump
 

Flow matching: The design flow of this pump type is highly compatible with customer needs, ensuring efficient and stable operation.

Medium adaptability: specially designed for particle free, low viscosity media, perfectly adapted for ether solvent transportation.

Sealing performance: The magnetic drive design achieves zero leakage, ensuring safe operation and environmental friendliness.

Motor configuration: 2-level variable frequency motor

Flow regulation: The variable frequency motor can flexibly adjust the pump speed according to actual needs, achieving precise flow control.

Energy efficiency optimization: By adjusting frequency conversion, energy consumption is reduced and overall operational efficiency is improved.

Summary of Reasons for Recommendation

Accurate matching: The 3.2CC-88 pump type flow rate perfectly corresponds to customer needs, avoiding resource waste.

Cost effectiveness: Reasonable selection reduces initial investment and long-term operating costs.

Safe and reliable: The magnetic drive design eliminates the risk of leakage and ensures safe operation.

Flexible adjustment: Variable frequency motors achieve on-demand flow regulation, enhancing system flexibility.
