Allweiler has made pumps since 1860 and is based in Radolfzell, Germany. The name is closely tied to three-screw pumps for lubricating and fuel oils, next to centrifugal and progressing cavity pumps. Seven Star LLC lists the Allweiler TRILUB TRL screw pump and supplies Allweiler pumps and spare parts to power plants, marine operators and process plants in Oman as an independent supplier.
Allweiler TRILUB screw pumps
TRILUB is Allweiler’s name for a family of three-screw pumps built for lubricating and hydraulic oil service. One driven screw meshes with two idler screws inside a liner and moves the oil axially with little pulsation, which suits lube oil circuits of turbines, compressors, gearboxes and diesel engines. The listed TRL V16-40R41 is a complete pump from this family. Buyers who search for Allweiler oil pumps are usually looking for this kind of unit, in the GCC as elsewhere.

Send the full type designation and the serial or order number from the nameplate. For a complete pump add the oil grade and viscosity, flow, discharge pressure, speed and motor data. For parts, name the item needed, such as the screw set, liner, mechanical seal or bearing.

Frequently Asked Questions
How do I identify an Allweiler screw pump from its nameplate?
The nameplate gives the type designation, for example TRL followed by size and design codes, together with a serial or order number, flow, pressure and speed. The characters after the series name define the size and design of the pump, so one changed digit means a different pump. Send a nameplate photo and we will check the designation in the manufacturer's documents.
What liquids are TRILUB three-screw pumps meant for?
They are designed for lubricating liquids without abrasive solids, mainly lube oils, hydraulic oils and light fuel oils. The screws are supported by the pumped liquid film, so clean oil of suitable viscosity is essential for long life. If your liquid is contaminated, very thin or non-lubricating, tell us, and we will ask which Allweiler series the manufacturer specifies for it.
Is Seven Star LLC a distributor of Allweiler?
No. Seven Star LLC is an independent supplier and is not an authorized distributor or agent of Allweiler. We source Allweiler pumps and parts through commercial channels, check the type designation and serial number against the manufacturer's documentation, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order, on request.
What should I send for a quotation on Allweiler spare parts?
Send the pump type, the serial or order number and the part names or position numbers from the sectional drawing in your manual. With the serial number the manufacturer can identify the exact screw set, liner and seal version. If the nameplate is missing, send dimensions, photos and the machine the pump serves.
