Why a Diaphragm pump could be the ideal choice for your application

Countless industries worldwide rely on industrial pumps to ensure consistent, high-performance operations. The reliability of these pumps, particularly air-operated diaphragm pumps, is essential. Unplanned downtime can result in costly production halts, expensive repairs, and product losses. Therefore, selecting the right diaphragm pump for industrial applications — such as chemical processing, food production, or handling corrosive liquids — is crucial for minimizing risks and optimizing efficiency.

For industries demanding corrosion resistance, hygienic handling (such as food-grade pumps), and safe operation in explosive environments (ATEX-certified equipment), SAMOA air-operated diaphragm pumps provide a dependable solution tailored to the most challenging conditions.

But how do you choose the right diaphragm pump?
SAMOA’s air-operated diaphragm pumps deliver versatility and reliability, whether handling aggressive chemicals, high-viscosity fluids, or applications in water treatment and the petrochemical sector. Experience the advantages of choosing a SAMOA diaphragm pump – engineered for industrial durability, operational safety, and peak efficiency.
Wide range of applications
One of the biggest advantages of SAMOA air-operated diaphragm pumps is their versatility as they can handle a wide range of liquids including shear-sensitive, highly viscous fluids, slurries, abrasives and corrosive substances. With the right design and materials, these pumps can be tailored to specific installation needs without compromising the pump or the final product. They also handle liquids with suspended particles, making them suitable for demanding applications and harsh environments.

Thanks to their flexibility, SAMOA air-operated diaphragm pumps are widely used across industries such as chemical processing, ceramic manufacturing, water treatment and energy production. Common applications include tank loading and unloading, liquid dosing and mixing, recirculation, transfer, water treatment, coating and mold filling. Industries that rely on SAMOA diaphragm pumps include petrochemical, mining and construction, paint and coating, pulp and paper, textile, mechanical and civil engineering, ceramics, marine, power generation, tank farms and bulk transfer, wastewater treatment and electronics.
More performance advantages
In addition to their versatility SAMOA air-operated diaphragm pumps offer several performance advantages over other pump technologies in both operation and cost-efficiency. They can run dry without damage and generate no heat during operation. Their self-priming capability makes them ideal for suction lift applications. With no electrical components SAMOA diaphragm pumps are safe for use in explosive environments with ATEX-certified models and can operate fully submerged without compromising performance.

SAMOA diaphragm pumps are a cost-effective solution due to their simple design and low maintenance requirements. They start automatically when the liquid outlet is opened making integration into existing pumping systems easy. Flow rate and outlet pressure are easily controlled with an air pressure regulator. The absence of mechanical seals reduces maintenance time and costs making SAMOA diaphragm pumps an economical and reliable choice for various industrial applications.
Common applications and pump sizes
SAMOA diaphragm pumps can be categorized by application sales channel and industry. Below are common categories and sizes for various applications.

OEM applications
Pumps integrated into equipment and systems such as concrete mixers require compact solutions. Sizes like 1/4 inch 3/8 inch and 1/2 inch are common as they provide low flow rates and are easy to install in confined spaces.

Ink and paint applications
1/2 inch metal pumps from SAMOA are frequently used for pumping ink or paint with viscosities up to 3000–4000 cPs. Diaphragm material is selected based on the liquid whether water-based or solvent-based. In paint manufacturing 2 inch and 3 inch metal pumps are standard for large liquid volumes while 3/8 inch and 1/2 inch pumps are common in spray equipment for paint booths.

Wastewater and waste oil applications
For wastewater treatment 2 inch and 3 inch pumps are primarily used while versatile 1 inch pumps are popular due to their flexibility and capacity in these applications.

Ceramics and mining industry
In the ceramics and mining industries 2 inch and 3 inch SAMOA diaphragm pumps are a preferred choice due to their robust construction and high flow capacity between 650 and 1000 liters per minute handling ceramic glazes slurries and abrasive liquids under demanding conditions without compromising performance.
Combining versatility performance and cost-effectiveness SAMOA air-operated diaphragm pumps are an optimal choice for a wide range of industrial applications.

Ceramics and mining applications
The ceramics and mining industries typically use 2 inch or 3 inch SAMOA pumps delivering high flow rates between 650 liters per minute and 1000 liters per minute Their robust construction makes them ideal for demanding environments handling ceramic glazes water with suspended particles slurries and abrasive liquids while maintaining reliable performance

Chemical industry
In the chemical industry SAMOA pump sizes vary depending on flow requirements Specialty chemical companies often use 1 inch to 2 inch pumps while basic chemical production relies on larger sizes like 1 and a half inch 2 inch and 3 inch Stainless steel or non-metallic SAMOA pumps with PTFE diaphragms are the most common material combinations in this sector

General manufacturing
In general manufacturing 1/2 inch SAMOA pumps are widely used for unloading drums and sacks Wastewater treatment processes in manufacturing industries frequently use pumps from 1/2 inch to 2 inches with PTFE or Santoprene diaphragms depending on the water’s pH
