Introducing the piab piEVO Vacuum Ejector Pump

In industrial dry material handling and pneumatic conveying, operational throughput hinges on system reliability, response speed, and maintenance ease. To help processing plants achieve higher productivity with fewer unplanned stops, R-CAP Process Equipment is proud to introduce Piab’s next-generation vacuum ejector pump platform: the piEVO.

Engineered as the modern foundation for Piab’s vacuum conveyor portfolio, the piEVO replaces the established piPREMIUM 100-400 series while utilizing proven ejector technology. Whether you are retrofitting existing conveying lines or designing new processing systems, the piEVO delivers flexible mounting options, reduced noise emissions, streamlined serviceability, and 100% unit-level traceability.

The piEVO platform introduces several key engineering enhancements designed to reduce maintenance duration and simplify single-person installations in tight processing environments.

1. Twist-Lock Bayonet Conveyor Interface

Connecting the vacuum pump to the conveyor body is now faster and safer. The piEVO features a twist-lock bayonet and flange connection that enables quick, one-handed fitting. Secured with bolts directly to the main housing, this interface can be easily replaced or adapted for various conveyor configurations.

2. Multi-Line Quick Connectors

Managing pneumatic connections during maintenance is significantly simplified. The supply and output pressure tubes are secured via a unified quick connector block, allowing operators to disconnect and reattach the pneumatic lines as a single unit without removing individual fittings.

3. High-Efficiency Ejector & Silencer Module

• Ejector Capacity: The central ejector module holds up to 16 ejectors and is fully compatible with existing Si32 3 (Coax®) cartridges, as well as Piab’s upcoming high-flow ejectors.
• Low Noise Emission (<78 dB): An internal silencer crafted from open-cell PUR foam with streamlined flow channels dampens operating noise to below 78 dB.
• Versatile Exhaust Management: The suction port includes an integrated exhaust outlet, allowing operators to either vent exhaust air directly into the environment or connect a line to route process exhaust away from the work zone.

4. Space-Optimized Control Compartment

Fastened directly into the main housing, the bottom cover and air supply compartment house critical pneumatic control components. This compact design facilitates rapid disassembly with standard tools and supports seamless integration of supplemental automation accessories, such as automated Filter Monitoring systems.

Beyond physical hardware improvements, the piEVO platform prioritizes operational safety, regulatory compliance, and lifecycle management:

• Integrated Safety Functions: Standard built-in blow-off capabilities and non-return valves prevent back pressure issues and protect system integrity.
• Global Regulatory Standards: The piEVO platform carries full coverage under CE, REACH, and RoHS regulatory frameworks.
• 100% Serialized Traceability: Every piEVO pump is assigned a unique serial number registered during factory assembly. This serial number links the physical unit directly to its specific build configuration in digital platforms like MyProduct/MyPiab. For plant managers and maintenance teams, this complete traceability speeds up root-cause troubleshooting, ensures precise spare parts ordering, and eliminates guesswork during maintenance cycles.

The piEVO vacuum ejector pump is optimized for demanding dry material processing operations where consistent flow and fast response times are critical. Key industry applications include:

• Food & Beverage: Conveying powders, spices, granules, and delicate ingredients without material degradation.
• Pharmaceutical & Nutraceutical: Transferring active pharmaceutical ingredients (APIs) and powders while maintaining strict sanitary compliance.
• Chemical & Industrial Processing: Moving bulk dry materials efficiently through closed-loop pneumatic systems.
• Pet Food Manufacturing: Managing consistent raw ingredient feed rates into mixers and extruders.
