Thanks to these innovations, the pumps are suitable for a wide range of application needs, ensuring reliability, efficiency, and versatility even in extremely demanding industrial environments.

Why Choose ProOne AODD Pumps

Designed and manufactured by PCHEM, the ProOne series of air-operated double diaphragm pumps feature the following key innovations:

• Dual Anti-Stall valve with wear recovery: engineered to ensure high reliability and fast, on-site maintenance without removing the pump from the system.
• Ready for electronic monitoring: ideal for smart integration with PLCs and data acquisition systems. See more.
• Modular exhaust air management system: a flexible and modular solution designed to adapt to the customer’s technical requirements. See more.

PCHEM ProOne AODD Pumps are also robust and reliable, tested under extreme conditions and with aggressive liquids. The result? Exceptional durability and consistent performance even in the toughest environments. Thanks to their ability to handle corrosive and abrasive fluids, these pumps are truly multi-application and multi-material, making them ideal for a wide range of industrial sectors.

They are particularly suitable for applications in industries such as:

Energy Efficiency and Sustainability to Reduce Costs and Environmental Impact

In an era where industry is called upon to reduce environmental impact and optimize resources, having products designed with energy efficiency and sustainability in mind represents a key strategic advantage. Innovative solutions capable of minimizing consumption and waste not only contribute to environmental protection but also allow for significant reductions in operating costs. The adoption of sustainable technologies also facilitates compliance with increasingly stringent regulations on emissions and waste management.

Companies that invest in efficiency and sustainability stand out in the market, enhancing both their value and reputation. In this way, responsible choices become key factors for competitiveness and long-term growth.

For this reason, PCHEM ProOne AODD pumps are designed with sustainability at their core: they maximize energy efficiency by reducing air consumption and eliminating harmful air volumes. PCHEM ProOne pumps can operate at low pressure, requiring up to one third less air pressure compared to leading competitors. In addition, they are ready for the installation of an electronic sensor that can detect and stop dry running, ensuring considerable energy savings.

PCHEM ProOne double diaphragm pumps are engineered and built to last, manufactured with high-quality materials and offering configurations that include components made from recycled raw materials.

AODD Pumps with real-time monitoring: reduced downtime and increased plant safety

AODD pumps operate without electrical or electronic components and therefore cannot communicate directly with machine or plant control systems such as PLCs. However, being able to monitor pump status and performance in real time, directly from the plant, is today a crucial added value: it allows anomalies to be prevented, processes to be optimized, and greater operational safety and reliability to be ensured. Electronic integration enables precise control, minimizing unexpected downtime and enhancing smart plant management.

PCHEM ProOne pumps, fully compatible with Industry 4.0 and 5.0, can be electronically monitored and integrated with PLCs and data acquisition systems for multiple measurements, including:

• Measuring flow rate
• Monitoring liquid viscosity
• Tracking air consumption
• Detecting dry running
• Analyzing operational performance

Superior Efficiency with PCHEM ProOne AODD Pumps: Flow Rate Increase up to +12%

The PCHEM ProOne AODD pumps are the result of meticulous, optimized, and highly efficient design — the outcome of significant engineering effort and an extensive technical development phase. Their outstanding performance, including a flow rate increase of up to +12% compared to leading competitors*, has been achieved through targeted design choices and a relentless pursuit of excellence in construction details.

Reaching these results was no easy task: the development of linear fluid-dynamic channels and the optimization of internal volumes required numerous iterations and rigorous testing, successfully overcoming complex technical challenges. The result is a range of pumps that stand out for operational efficiency, fast cycle times, and maximum reliability in the most demanding applications.

Silent Power, Maximum Productivity

In today’s industrial context, noise reduction is a key factor — both for employee well-being and for compliance with current health and safety regulations. Low noise emissions help create a safer working environment, reduce the risk of hearing damage, and improve operator concentration, ultimately boosting productivity and work quality.

Thanks to an innovative exhaust air system, the noise level of PCHEM ProOne pumps is drastically reduced, reaching values up to -14 dB[A] compared to leading competitors*. An internal chamber dissipates the energy of the compressed air before release, while a threaded connection allows the use of external silencers to further lower sound pressure levels.

Configurable Solutions for Every Need

The ProOne air-operated double diaphragm pumps can be specifically configured to meet precise operational and technical requirements, thanks to a wide range of design and functional options. Among the main configuration possibilities are separate suction and discharge, low-pulsation solutions, reduced internal volume, operation via external control, and many other technical variations.

This high degree of design flexibility allows each pump model to be precisely tailored to the actual operational needs of the plant, ensuring optimal performance even in the presence of particularly stringent requirements or unconventional operating conditions.

Fast and Simplified Maintenance

In industrial environments, process pump maintenance plays a key role in ensuring plant safety, operational continuity, and efficiency. These devices are often subjected to heavy-duty conditions, continuous cycles, and aggressive fluids — factors that make timely and scheduled maintenance essential.

Regular servicing prevents unexpected failures, minimizes downtime, and reduces costs associated with emergency repairs or premature replacements. Moreover, proper maintenance helps preserve pump performance, safeguard component integrity, and ensure product quality. From the perspective of efficiency and safety, maintenance is therefore not just a technical task but a true strategic investment in company productivity and workplace protection.

Maintenance has not only been considered but has served as a central pillar in the design phase of PCHEM ProOne pumps. Every technical choice was guided by the goal of simplifying and speeding up service and inspection activities. For this reason, PCHEM ProOne pumps:

• Are built with a reduced number of components
• Include standardized parts across multiple pump sizes
• Allow on-site replacement of both pilot and power air valves without removing the pump from the system
