Plastic Pumps: The Ideal Choice for Transporting Acids and Hazardous Liquids

In the chemical industry, safely and reliably transporting acids and hazardous liquids is critically important. Plastic pumps are an ideal choice for this application due to their corrosion resistance, heat resistance, and ease of maintenance. As an experienced pump manufacturer with over 10 years of experience producing specialty material pumps, QEEHUA PUMP utilizes polypropylene (PP) and fluoropolymers (PVDF) to ensure compatibility with a variety of liquids including acids, bases, oils, alkalis, refrigerants, and fuels.

Characteristics of Plastic Materials

We choose plastic materials for our pumps mainly due to the following characteristics:

Polypropylene (PP) Pumps

  • Corrosion resistance: PP is a highly resistant polymer that can be used with many liquids such as caustic soda and acidic liquids.
  • Mechanical strength: Reinforced with additives like glass fibers and talc for enhanced compressive mechanical strength.
  • Operating temperature range: PP pumps can safely handle fluid temperatures of approximately 60-70°C.

PVDF Plastic Pumps

  • Chemical inertness: PVDF is a fluoropolymer that is chemically inert to most chemicals, suitable for a wide range of liquid types.
  • Heat resistance: PVDF has a higher heat resistance capability than PP, and can be used at temperatures up to 90°C.

Advantages of QEEHUA PUMP Plastic Pumps

  • Corrosion resistance: Manufactured from high corrosion-resistant materials like PP and PVDF to be compatible with various acids, bases, salts, and other chemicals.
  • Heat resistance: PP pumps suitable for liquids up to 60-70°C, PVDF pumps suitable up to 90°C.
  • Easy maintenance: Simple structure allows for easy disassembly, cleaning and maintenance.
  • Cost-effective: More affordable than metal pumps with a longer service life.

How to Select the Most Suitable Pump Material

To ensure selecting the most suitable pump material, you need to:

  • Understand liquid compatibility: First, understand the liquid needing transport and verify its compatibility with potential pump materials. Use our chemical compatibility charts for assistance.
  • Consider temperature requirements: Select a suitable pump material based on the liquid’s temperature. PP is suitable for liquids up to 60-70°C, PVDF up to 90°C.
  • Consider cost vs performance: Balance cost and performance when choosing. PVDF has a higher cost but greater heat and chemical resistance suitable for more demanding applications.
