In the tank farm and batch material transfer sections of chemical production, the short-cycle transportation of highly corrosive process fluids has always been a core pain point in equipment selection. The fluoroplastic self-priming pump is a corrosion-resistant conveying device developed specifically for the characteristics of chemical workstations, which precisely meets the operational requirements of chemical tank farms.

I. Precise Adaptability to Chemical Application Scenarios

Its application is fully compatible with the typical working conditions of chemical production lines:

1.Adaptability to short-duty cycles in tank farms: Suitable for short-time operation scenarios such as tank truck unloading of acids/alkalis, water intake from low-level raw material pools, and batch material transfer, matching the "batch-wise, intermittent" operational rhythm of chemical production lines.

2.Compatibility with highly corrosive media: It can stably transport core chemical process fluids including concentrated acids, strong alkalis, salt solutions, and organic solvents. Meanwhile, it is capable of handling hazardous waste media like chemical wastewater containing a small amount of solid impurities, waste acid, and waste alkali liquor.

II. Outstanding Features of Chemical-Grade Design

Targeting the corrosion resistance, safety, and compliance requirements in the chemical industry, its design incorporates multiple industry-specific adaptability features:

1.Specialized structure for tank farm workstations

Adopting an external mixing double-layer pump body with built-in self-priming function, it is specially designed for chemical tank farm workstations. It can achieve self-priming without the need for a pre-installed priming device, perfectly adapting to the layout characteristics of "low-level storage and intermittent transfer" of materials in tank farms.

2.Dual-performance material with corrosion and pressure resistance

The flow-passing components are made of fluoroplastic materials available in PFA, PVDF, ETFE, or FEP, which can resist long-term erosion by highly corrosive media in the chemical industry. The load-bearing section of the pump uses a metal matrix to meet the pressure-resistant process requirements of chemical systems, balancing corrosion resistance with the mechanical strength of the equipment.

3.Chemical-compliant sealing solution

It supports the configuration of externally mounted single-face mechanical seals and externally mounted cartridge mechanical seals with flushing water. Customizable flushing schemes complying with the API 682 standard for the chemical industry are available, meeting the sealing safety and industry compliance requirements for the transportation of high-risk media.

4.Medium-adaptive self-priming parameters

The self-priming height (vertical distance from the liquid level to the pump chamber) is dynamically adjusted according to the density of chemical media, with a range of 1–3 meters, precisely matching the physical property requirements of different process fluids.

In chemical batch transfer, hazardous waste treatment, and other processes, this fluoroplastic self-priming pump, with its chemical-grade corrosion resistance and workstation adaptability, supports the efficient and safe transportation of highly corrosive media under short-duty cycles, making it a practical core device for material circulation in chemical tank farms.
