Balls

Pump balls are an important component of diaphragm pumps. The ball, along with the ball seat, functions similarly to a check valve in a pump, helping to regulate the flow of the liquid being pumped. Over time, the ball may wear out due to high pressure, harsh temperatures, etc. Choosing the right material as well as regularly inspecting and replacing worn or damaged balls helps minimize the risk of pump failure.

Currently, there are many types of pump balls available, such as EPDM, Nitrile, PTFE, stainless steel, Viton, Santoprene, etc., suitable for various diaphragm pump manufacturers and different types of check valve applications.

However, it is essential to select the correct material for the pump ball based on the liquid to avoid damage during use. For particularly viscous, thick, or heavy liquids, stainless steel balls should be used. Note:

For diaphragm pumps, if the suction range exceeds 3 meters, Santoprene balls should not be used as they can reduce the pump’s suction power.

Heavier balls are generally better, but stainless steel balls should only be used with diaphragm pumps that have pump bodies made of cast iron or stainless steel. They should not be used with other pump materials as this can lead to quicker pump failure.

Factors Affecting the Performance of Pump Balls

Material of Manufacture

• Wear Resistance: The materials used for pump balls need to have high wear resistance to ensure a long service life and stable performance.
• Chemical Resistance: For chemical pumping applications, the materials must resist chemical corrosion.

Size and Accuracy

• Pump Ball Size: The size of the pump ball needs to be accurate to ensure it operates effectively with the diaphragm pump’s valves. Balls that are too large or too small can cause leaks or poor performance.
• Precision: The pump ball needs to be precisely machined to ensure it fits snugly with the valve surfaces in the system.

Condition and Maintenance

• Wear and Damage: During use, pump balls can wear out or get damaged. Regular maintenance and timely replacement of worn or damaged balls are crucial to maintain pump performance.
• Periodic Inspection: Regular checks are necessary to detect early signs of wear or damage and take corrective actions such as repairs or replacements.

Common Pump Balls Materials at

• Neoprene: Used in water-based sludge processing plants, well water, or seawater. Commonly green. Some pump manufacturers may use specific brand colors.
• Buna-N/Nitrile: Applied in industries dealing with petroleum-based liquids like leaded gasoline, fuel oil, non-synthetic hydraulic oil, kerosene, paraffin oil, and engine oil. Commonly red.
• EPDM/Nordel: Used in industries with low or extremely low temperatures or as a replacement when pumping diluted acids or corrosive substances. Commonly blue.
• FKM/Viton: Suitable for high-temperature industries and liquids with corrosive properties such as aromatic hydrocarbons or chlorine and highly corrosive acids. Commonly silver or white.
• Santoprene: Used with acidic and corrosive substances such as sodium hydroxide, sulfuric acid, or hydrochloric acid. Offers good wear resistance and durability. Commonly cream.
• Hytrel: FDA-approved for food processing applications. Commonly cream, with some brands using alternative colors.
• Geolast: Suitable for various types of liquids. Commonly black.
• PTFE: Used for highly corrosive liquids such as aromatic hydrocarbons or chlorine, acids, corrosive substances, ketones, and acetates. Commonly white.
• Stainless Steel: Excellent chemical resistance and suitable for food processing applications due to ease of cleaning and corrosion resistance.

Importance of Pump Balls in Diaphragm Pump Systems

Pump balls are essential components in diaphragm pump systems, playing a key role in regulating flow and maintaining pressure. Understanding their construction, function, and the factors affecting their performance will help users optimize diaphragm pump operation, ensure efficient and stable system performance, and extend the equipment’s lifespan. Choosing the right type of pump ball suitable for the specific application and operating conditions can help optimize pump performance, minimize downtime and maintenance, thereby enhancing efficiency and reducing operational costs. Regular maintenance and inspection of pump balls are also important to keep the pump operating smoothly and reliably.

How Can We Assist You?

We offer a wide range of diaphragm pump balls in various sizes and common materials. Each pump brand and type has different designs, so accessories need to match each pump type. Therefore, parts may vary in shape, mounting hole count, and size. It’s advisable to have spare pump balls available to minimize downtime and maintain pump efficiency.

However, not all brands have readily available stock, and prices can be high. It’s essential to have alternative solutions that meet quality requirements, ensure prompt service, and meet necessary production criteria.

we provide a comprehensive selection of diaphragm pump balls and other replacement parts from well-known brands like Aro, Sandpiper, Wilden, with competitive prices, excellent quality, and large quantities. Parts are shipped worldwide from our Vietnam warehouse.
