BECKER oil-free vacuum pumpsfor industry

In these machines, the ability to recover vacuum quickly after each pick is often more important than ultimate vacuum alone. Sizing should account for suction-cup and piping volume, expected leakage, surface material, simultaneous axes and cycle frequency. This application should be distinguished from chamber packaging or processes requiring deep vacuum or handling high vapour loads, which may need different technology. If demand varies significantly during the cycle, a VARIAIR solution may be attractive after the real demand profile has been defined.

BECKER explicitly documents dry-vane technology in woodworking and highlights the X Series — VX, KVX and VXLF — for demanding dry-vacuum duty; VARIAIR can also be considered when demand fluctuates. To size a CNC vacuum table, define the working surface, number of zones, sacrificial-board porosity, manifold diameter and length, filtration and permissible pressure losses. Fine dust is a critical service factor: inadequate filtration can reduce performance and accelerate wear. Select on the flow required at the actual holding pressure, not on nominal flow alone.

An important point in printing machinery is that the process may require both vacuum and blow air. If the pneumatic architecture needs both functions, a vacuum-only pump may not be the correct solution and combined systems or compressors should be considered. For the vacuum side, evaluate paper format and weight, number of suction cups, feed frequency, leakage, hose length and dust sensitivity. BECKER includes oil-free rotary-vane pumps for printing and paper applications; the specific family depends on the required flow and vacuum level.

Sizing must start from the volume to be evacuated, initial and final pressure, available evacuation time, piping conductance, mould tightness and intake-gas temperature. For sheet holding during cutting or machining, leakage compensation can become more important than initial evacuation. Clean air must also be distinguished from vapours or entrained material. Dry pumps perform best with properly conditioned gas; if condensate, plasticizers or particles may be drawn in, suitable separation and filtration should be added or another technology considered.

BECKER specifically presents the VT and KVT series for Pick & Place applications. The calculation should consider the effective area of each suction cup, part material and surface roughness, acceleration, load orientation, internal volume, leakage and simultaneity. Sensors, check valves and, where appropriate, a small buffer receiver can improve system reliability. If demand changes substantially between standby and handling states, speed control can improve efficiency. Final model selection must be based on flow at operating pressure, not motor power alone.

An industrial pump alone is not equivalent to a certified medical vacuum system. The integrator must verify regulatory requirements, redundancy, filtration, liquid separation, alarms, gas quality, material compatibility and maintenance strategy. Medical or OEM equipment must also consider noise, vibration, space, ventilation and service access. Where liquids or aerosols may enter the suction line, they must be prevented from reaching the pump. Exportvacio can support vacuum-generator selection, while sanitary and functional validation remains the responsibility of the final-system manufacturer or integrator.

Vacuum sewer systems use a pressure differential to move wastewater toward collection or treatment stations. Selection must consider piping length and geometry, valve-opening frequency, air ingress, simultaneous flow and protection against liquid carry-over.

The calculation must relate product type and density to solids throughput, piping diameter and length, elevation, number of bends, filters and pressure losses. Excessive conveying velocity can degrade product, erode piping or increase energy use; insufficient velocity can cause settling and blockages. Receiver-filter loading changes the operating point over time. Before selecting a BECKER pump, define the required air flow and vacuum in the most demanding scenario and confirm that both product and gas are compatible with dry-vane technology.

The designer should specify required vacuum, flow, leakage, part sensitivity, permissible vibration, sound level, enclosure temperature and service access to filters and vanes. In clean-room component handling, exhaust architecture and thermal management must be assessed as part of the complete system. BECKER also documents electronic-component Pick & Place in centralized systems. For OEM machinery supplied to Africa, Asia and the Middle East, voltage, frequency, altitude, ambient temperature and destination operating conditions should be confirmed at order stage.
