In industrial fluid handling, pump reliability depends on design and material selection. Diaphragm pumps must withstand continuous operation, repeated pressure cycles, and long-term exposure to liquids that may range from neutral solutions to aggressive chemicals.
The pump head is one of the most critical components in diaphragm pump systems. Many manufacturers rely on metal solutions to guarantee strength and durability. However, modern industrial engineering is increasingly moving toward metal replacement using high-performance thermoplastics providing excellent chemical resistance, dimensional stability, resistance to fatigue and production efficiency.
This is the approach adopted by Electro A.D., S.L., a Spanish manufacturer specialized in diaphragm vacuum and pressure pumps, which selected PPS based compounds of LATI’s LARTON family for pump head and structural components in diaphragm pumps.
Electro A.D.: A Trusted Manufacturer of Diaphragm Pumps
Based in Masquefa (Barcelona, Spain), Electro A.D., S.L. is a well-established company focused on the design and production of diaphragm pumps for industrial and technical applications. The company is known for its engineering-driven approach, quality manufacturing standards and commitment to long-term performance.
Electro A.D. serves markets where stability, safety and durability are essential, and where pump systems must operate reliably even under demanding working conditions.
The Challenge: Pump Head Resistance to Chemicals and Temperature
The pump head is directly exposed to the fluid flowing through the system. Depending on the application, diaphragm pumps may handle different chemical media, which means the pump head must remain stable and resistant even when liquids vary.
Electro A.D. required a solution able to guarantee:
- high chemical resistance across multiple pumped fluids
- strong mechanical integrity and fatigue resistance under pressure cycles
- thermal stability in continuous operation
- dimensional precision for sealing and assembly
- consistent performance and reliability over time
Why PPS is Ideal for Metal Replacement in Pump Applications
Electro A.D. identified Polyphenylene Sulphide (PPS) as the best polymer base for this application.
PPS is widely used in high-performance industrial components thanks to its excellent balance of properties, including:
- very good chemical resistance
- high thermal stability
- excellent dimensional stability
- low moisture absorption
- strong mechanical performance retention
- intrinsic flame retardancy
Achieving the best performance requires a specialized PPS thermoplastic compound designed for industrial reliability and injection molding consistency.
LATI Solution: PPS LARTON Thermoplastic Compounds
To meet these requirements, LATI provided two grades from its LARTON PPS compound portfolio, designed for demanding engineering applications.
The PPS grades selected for Electro A.D. are:
- LARTON G/40
A glass fibre reinforced PPS compound designed for high stiffness and mechanical strength. It offers excellent fatigue resistance and outstanding thermal performance, making it suitable for structural pump components.
- LARTON GCE/600 BLACK (Grade 3302 Y1)
PPS compound featuring glass fibres and mineral filler. This grade is engineered to provide high dimensional stability suitable for complex molded geometries.
Chemical Resistance: Performance Regardless of the Pumped Liquid
A key reason for choosing PPS LARTON compounds is their ability to deliver reliable performance across different chemical environments. In this case, the pump head must resist chemical attack and maintain its mechanical integrity over time.
PPS is known for its very good resistance against many aggressive substances, helping reduce the risk of degradation, cracking or dimensional instability.
Compared to metal, PPS compounds also eliminate corrosion-related issues, contributing to long-term durability and increased safety.
Conclusion
The collaboration between Electro A.D., S.L. and LATI demonstrates the value of engineering thermoplastics and advanced PPS compounds in modern industrial equipment design.
By selecting LARTON G/40 BLACK (3355) and LARTON GCE/600 BLACK (3302 Y1), Electro A.D. implemented a robust metal replacement solution for diaphragm pump heads, achieving chemical resistance, thermal stability and long-term mechanical reliability.
For manufacturers looking for technical plastics and thermoplastic compounds capable of replacing metal components in demanding applications, LATI PPS LARTON materials represent a proven and effective solution.
