Selection of corrosion-resistant pumps

2009-03-29View Original

Thread Content

Our company is a enterprise engaged in the deep processing of coal chemicals; in the washing process, there is a medium called indole acid oil. Indole is present in dilute sulfuric acid at concentrations of 20% to 40%. This substance tends to polymerize and floats in sheets within indoleic acid oil. These sheets of indoleic acid oil can be drawn into threads, and the material remaining in the pump after pumping will solidify into a brittle solid, which can easily damage the mechanical seal. Our company has used both 316L centrifugal pumps and fluorocarbon magnetic pumps, but neither of them has lasted long. Could someone give me some advice?

Our company’s unsaturated polyester resin pumps possess unique technology in terms of corrosion resistance, and we would like to discuss this with you. 13718589112 Mr. Liang

A double-end mechanical seal combined with flushing is used to prevent residues from crystallizing in the seal chamber.

I also recommend using a positive displacement pump; the key factors are flow rate and head. If temperature sensitivity is a concern, should a thermal insulation jacket be added?

Vertical semi-open impeller plastic centrifugal pump is the best

Could you specify the requirements regarding medium flow rate, temperature, and pressure?
