Series Low Pressure Screw Pumps TRILUB TRD from the company Allweiler They are designed to work with oils of various natures in hydraulic systems and general industrial installations. Self-priming, used in applications with low flow rates in a wide range of industry areas. The design of the pump rotor is based on three screws: one main drive screw and two idling screws for sealing. The rotation of the screws is carried out without mechanical action relative to each other, which allows you to maintain low noise and vibration. All structural components are perfectly balanced, axial loads are smoothed out, radial loads are excluded.
Built-in mechanical shaft seal, there is a pressure relief control valve for overload protection. A support platform is used for installation. Standard electric motors (IEC 71 size), direct connection are used for the drive.
Pumping liquids: natural and synthetic oils, hydraulic fluids.
Limitations: no abrasive particles, contact with chemically aggressive agents.
Areas of application: oil industry, mechanical engineering, pressure generation in hydraulics, supply of lubricants in various technological processes.
