Pneumatic diaphragm pumps as an assistant in transferring daily chemical solvents

Sep,19,2025

In the chemical and detergent manufacturing industry, selecting the right chemical pump is crucial for ensuring equipment performance, operational safety, and long service life. Pneumatic diaphragm pumps—especially those powered by compressed air—have become the preferred solution, enabling factories and production facilities to efficiently handle corrosive solutions, strong solvents, viscous liquids, and foaming fluids without the risks of leakage or damage commonly associated with traditional pumps.

With a flexible and robust operating mechanism, chemical pneumatic diaphragm pumps not only deliver exceptional durability but also significantly reduce maintenance costs, enhance production efficiency, and preserve the quality of end products.

It is no surprise that a growing number of businesses are switching to industrial diaphragm pumps for detergent transfer, thanks to their superior corrosion resistance, operational safety, and energy-saving benefits.

Common Detergents and Associated Pumping Challenges
Detergents are often highly alkaline, mildly acidic, or contain organic solvents, leading to challenges such as metal corrosion, foaming, and environmental contamination. Below are some typical detergent types that require specialized pumping solutions:

  • Liquid Soaps and Dishwashing Liquids: Medium viscosity, prone to foaming; require gentle pumping to avoid agitation.
  • Disinfectants and Antiseptics: Highly corrosive to metals; demand chemical-resistant materials such as PTFE or stainless steel.
  • Household & Industrial Cleaners: Toilet, floor, and glass cleaners often contain strong alkalis (e.g., NaOH) that can degrade standard pumps.
  • Machine and Equipment Cleaning Solutions: May contain solid impurities; require self-priming and clog-resistant pump capabilities.

Given these properties,  diaphragm pumps stand out as the ideal solution. They are capable of handling fluids ranging from dilute to highly viscous, even with solid particles up to 9.4 mm in size. While chemical pumps made of PP, PVDF, or stainless steel may be suitable for less demanding applications, diaphragm pumps excel in versatility, safety, and overall reliability.

When to Choose a Diaphragm Pump for Detergent Applications

  • Handling viscous, foam-prone, or impurity-containing liquids that require self-priming and explosion-proof operation.
  • Transferring dilute yet corrosive solutions where high flow rates and cost efficiency are. needed.

Why Diaphragm Pumps Are the Most Efficient Choice

Detergents not corrode metals—especially aluminum and cast iron—but also pose health and environmental risks. Thus, pumps must be constructed from high-quality materials such as PTFE, 316 stainless steel, or polypropylene to withstand acids, alkalis, and solvents.

In practice, over 80% of businesses encounter issues with traditional pumps when handling detergents due to high alkalinity/acidity and viscosity. Diaphragm pumps address these challenges effectively through a dual-diaphragm design and pneumatic operation (2–8 bar pressure range), eliminating the need for direct electrical power and reducing fire and explosion hazards.

Key advantages of diaphragm pumps over conventional chemical pumps:

  • Exceptional Durability: Service life of 5–10 years, reducing replacement frequency and downtime.
  • Stable Performance: Flow rates from 22 to 1041 liters per minute, with self-adjusting output based on system pressure.
