New Schmalz Nozzle Technology for Efficient Vacuum Generation

Vacuum specialist Schmalz is presenting the new compact ejector series SCPS/SCPSi with new eco nozzle technology at the Interpack trade show. The energy-eicient vacuum generators are ideal for a wide variety of highly dynamic handling processes.

Schmalz’ new eco nozzle technology has further optimized the energy efficiency of the ejectors, reducing compressed air consumption by up to 15 percent during active vacuum generation. Schmalz has also increased the suction rate by approximately 15 percent, meaning that this series can safely handle not only airtight products, but also porous cardboard. The vacuum specialist has enhanced the compact ejectors SCPS/SCPSi for dense parts, too: The evacuation time for reaching -600 mbar, the point at which automated movements are enabled, has been reduced by up to ten percent in the new series.

Efficient vacuum generators with complete process monitoring
The new compact ejectors not only consume a minimal amount of energy, they also feature integrated energy and process control to help make the entire process more sustainable. The vacuum generators measure and monitor all energy and performance-related process data. An IO-Link master allows bidirectional communication with higher-level field-bus systems – providing clear advantages for users: They can read out and monitor the data in their control systems. This means that you can view and optimize the entire vacuum system’s energy consumption “from afar”. The system operator can quickly determine how efficiently the system is running and whether maintenance is required, which is essential for applications such as packaging processes in three-shift operation.

An even broader range of applications with the ejector module ecoPump SEP
Schmalz also offers the energy-efficient ejector module of the compact ejectors SCPS/SCPSi separately under the name “ecoPump SEP”, widening the range of potential applications even further: The compact ecoPump SEP is the ideal machine component for decentralized vacuum generation, for example in box erectors. Since it can be installed directly on the suction pad, line losses are minimal and, what’s more, the cycle times are incredibly short. Its broad operating range of -250 to -850 mbar makes it ideal for reliably handling a variety of workpieces. Even workpieces such as flexible cardboard or bags can be handled reliably thanks to the effective leakage compensation. The ecoPump SEP also allows division of vacuum systems into separate vacuum zones, without taking up a lot of space.

The ecoPump SEP is available with three different installation diameters (7, 13 and 22 mm) and different performance levels, as well as in two different types: a high-flow (HF) version that optimizes energy consumption for porous workpieces like cardboard, and a high-vacuum (HV) version especially for airtight workpieces like ampules. The helpful selection aid quickly guides the user to the right ejector module for his or her application – based on the workpiece, the distance between the module and the suction point, and the necessary suction rate.

Integration of the ecoPump SEP is simple and saves space because, on the machine side, the ecoPump SEP is positioned right where the vacuum is needed. To operate the ejector module, all you need is a compressed air line – no vacuum line to the suction pad is needed. Schmalz also offers the housing SFE, which allows installation right on the suction pad, while also acting as a retaining element for the suction pad. What’s more, the ecoPump SEP can also be inserted straight into a borehole on the machine side. The borehole shape is very simple to reproduce. This means that the module can easily be integrated into existing designs. The ecoPump SEP can also be removed, disassembled and cleaned without any tools.
