Selection notes

The technical data page is a one-page summary, so sizes, curves and material choices must be taken from the manufacturer for a specific duty. Give the flow, head, liquid and temperature when you ask for a quotation and the correct size and stage count can be chosen from the DIN EN 733 range.

The same hydraulics appear in the Allweiler NI inline pump, which offers the compact inline layout. For oils and lubricants the Allweiler screw pump range is the better match; see the Allweiler TRILUB TRL V16-40R41 screw pump. Other pumps are in the pump category.

About brand

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.

Ordering Allweiler pumps and parts: what we need

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.
