Alfa Laval Duracirc Aseptic Pumps FAQs:
How efficient is the Alfa Laval DuraCirc compared to other pumps?
DuraCirc provides significantly higher volumetric efficiency than traditional CPP pumps, resulting in energy savings and enhanced productivity.
What is an EHEDG certified aseptic pumps?
An EHEDG certified aseptic pumps is designed to meet the highest hygienic standards, suitable for sterile, contamination-free processing in food, pharmaceutical, and biotech industries.
What’s the difference between aseptic and sanitary pumps?
Aseptic pumps are built for sterile environments, often used with CIP/SIP systems. Sanitary pumps meet general hygiene standards but may not provide full aseptic protection.
Does the DuraCirc pumps meet hygiene standards?
Yes, it is fully EHEDG, FDA and 3-A certified, ideal for aseptic and hygienic environments.
The DuraCirc Aseptic Pumps construction features two rotors, housed within a pumping chamber, known as a rotorcase, with each rotor located on a shaft held rigidly within a gearcase. The two rotors are timed via timing gears in the gearcase, which along with shimming, ensures no rotor or rotor case contact. Rotor/shaft drive is typically provided via geared electric motor.
Due to the close internal running clearance within the pumping chamber, the rotation of the rotors continuously generates a partial vacuum in the suction port of the pumps as the rotors unmesh. This results in a localized pressure drop, which allows fluid to enter the pumps. The fluid is then transported around the channel by the rotor wings and the pressure generated as the rotor wings re-mash forces the fluid out of the discharge port of the pumps.
Duracirc Pumps Working principle
The rotor pistons rotate around the circumference of the channel in the Duracirc Pumps casing. This continuously generates a partial vacuum at the suction port as the rotors unmesh, causing fluid to enter the pumps. The fluid is transported around the channel by the rotor pistons, and is displaced as the rotor pistons re-mesh, generating pressure at the discharge port. The direction of the flow is reversible.
