Optimizing Vacuum System Performance with Online Capacity Testing

Vacuum systems are critical for efficiency, product quality, and cost control in industries from power generation to pharmaceuticals. Yet leaks or declining equipment performance can quietly erode reliability. With Bionetics’ online capacity testing, operators can evaluate system health under real operating conditions—without costly shutdowns—and make informed maintenance decisions.
Understanding the Impact of Vacuum Leaks
Leaks in vacuum systems can reduce efficiency, create backpressure, or disrupt industrial processes. Properly functioning vacuum equipment, such as Liquid Ring Vacuum Pumps (LRVPs) and Steam Jet Air Ejectors (SJAEs), are essential for removing air and non-condensable gases.

These systems are used in a wide variety of industries:
- Power Generation: Steam turbines condensers rely on vacuum systems to maintain optimal efficiency.
- Chemical & Petrochemical: Evaporation, distillation, and solvent recovery processes depend on reliable vacuum.
- Pharmaceutical & Food & Beverage: Freeze-drying, vacuum filtration, and concentration processes require precise vacuum control.
- Pulp & Paper: Vacuum drying and filtration operations rely on efficient LRVPs and SJAEs.
- Marine & Shipping: Shipboard condensers and boiler systems use vacuum ejectors for proper operation.
- Wastewater & Environmental: Dewatering, aeration, and degassing processes utilize vacuum pumps to optimize treatment systems.
Why Regular Testing Matters
The performance of vacuum systems directly affects overall process efficiency. Periodic capacity testing ensures that equipment always operates at peak levels, detects issues before they escalate, and supports long-term system reliability and efficiency
Bionetics recommends regular testing to establish performance curves for each unit, providing benchmarks for operational efficiency. If testing has not yet been conducted, default guidelines can be applied until a repeating test program is established.
How LRVP and SJAE Testing Works
SJAE Testing
Steam Jet Air Ejectors are evaluated by measuring mass flow versus absolute pressure at the suction inlet. These measurements help assess performance and overall system efficiency.
LRVP Testing

Liquid Ring Vacuum Pumps are tested by monitoring volumetric flow against suction pressure over time, providing insights into pump efficiency and potential degradation.
Streamlined Online Testing & Benefits with Bionetics
Traditional vacuum equipment testing often requires outages and OEM support, creating disruptions and expense. Bionetics’ online testing eliminates these hurdles. Using RheoVac probes, capacity and performance can be measured in real time while equipment stays in service. Probes can be moved between locations through ball-valve assemblies, providing a full system view.
Key benefits include:
- Reliable LRVP and SJAE capacity measurement
- Early detection of leaks and performance loss
- Root-cause analysis to distinguish air in-leakage from equipment degradation
- Data-driven reports to guide maintenance planning
- Reduced downtime and lower testing costs

Real-World Application
Online testing data allows operators to identify underperforming pumps or ejectors, quantify performance gaps, and take targeted corrective action. For example:
- In a chemical plant, RheoVac data can reveal an LRVP underperforming in a solvent recovery process.
- In a food processing facility, testing can detect reduced SJAEs efficiency during vacuum evaporation of liquid concentrates.
- In pulp & paper operations, monitoring ensures vacuum dryers operate at optimal levels, preventing production slowdowns.
In one plant, the RheoVac output highlighted a 0.2” Hg difference between two Nash AT 1004 LRVPs. A pump swap test confirmed one pump was underperforming, pulling less than a third of the volumetric flow compared to the other. This data-driven approach allowed operators to take targeted corrective action, resolving the problem in a fast and cost effective manner. Watch the Vacuum Pump Capacity Analysis Using RheoVac System
