Pumpen und Durchflusszähler mit Lebensmittelkontakt zählen zu den sog. „Lebensmittelbedarfsgegenständen“ und unterliegen strengen gesetzlichen Regelungen. Die Lutz PURE Serie beinhaltet Produkte, die gleichzeitig den ATEX-Richtlinien, der FDA-Verordnung und den europäischen Verordnungen nach 1935/2004/EG entsprechen.
When selecting a Pump tube, the correct seal type depends primarily on the properties of the pumped medium. The decisive factor is whether the medium tends to form deposits, crystallize, stick, or harden.
Pump tube with mechanical seal (GLRD)
Pump tubes with mechanical seals are the preferred choice when pumping media that tend to crystallize, stick, harden, or spoil. The mechanical seal prevents the pumped medium from entering the shaft guide tube. This reduces the risk of deposits and prevents the Drive shaft from seizing.
Another advantage is the simplified cleaning and flushing of the pump tube, particularly with demanding or changing media.
During operation, a thin lubricating film formed from the pumped medium develops between the sliding surfaces of the mechanical seal. For this reason, dry running must be avoided at all costs, as this can lead to rapid wear or damage to the seal.
Recommended for:
- crystallizing media
- sticky or hardening liquids
- perishable pumped media
- applications with increased cleaning and flushing requirements
Seal-less Pump Tube (DL)
Seal-less Pump tubes are suitable for all applications where the pumped medium does not cause critical deposits or scaling. Since there is no mechanical seal, these pump tubes have a simpler design and are less sensitive to brief dry running.
Short-term dry running does not usually cause immediate damage to the Pump tube. Nevertheless, dry running should always be avoided to prevent unnecessary wear and maximize the Pump’s service life. Operation should therefore always be supervised.
Recommended for:
- non-critical, clean, or low-viscosity fluids
- Applications without a tendency toward deposits
- Applications with the possibility of short-term dry running
Conclusion:
If the pumped medium tends to crystallize, stick, harden, or spoil, a pump tube with a Mechanical seal should generally be used. In all other standard pumping applications, a seal-less pump tube usually fits.
