ALLWEILER TRILUB TRL V16-40R41 SDCREW Pump Complete

Overview

Advanced Three-Screw Pump Technology

The Allweiler TRILUB TRL V16-40R41 SDCREW Pump Complete is part of the TRILUB® series — Allweiler’s family of three-screw pumps engineered for lubricating liquids and industrial oils. Based on positive displacement screw technology, this pump is optimized to provide consistent flow, minimal pulsation, and long service life even in harsh conditions. 

This model (TRILUB 40R41U18-V-W117) is commonly used as a booster pump for oil systems, including booster service on large turbine/generator sets and industrial lubrication circuits where smooth and reliable oil transfer is critical for system safety and operational continuity. 

Technology & Design

The TRILUB TRL series uses three intermeshing screw spindles within a precision-machined housing. As the screws rotate, sealed chambers are formed that transfer fluid from the suction side to the discharge side with very low flow pulsation and almost no shear, preserving the integrity of sensitive lubricants and reducing mechanical stress. 

Key design features include:

• Three-screw positive displacement mechanism for smooth, continuous flow

• Low pulsation and noise operation, ideal for booster oil and lubrication systems

• High efficiency over a range of viscosities, suitable for industrial oils and hydraulic fluids

• Balanced axial loads to extend bearing and seal life

• Rugged construction for extended service life in industrial environments 

Performance & Fluid Handling

While the exact performance curve depends on installation and drive speed, TRILUB pumps in this series typically handle:

• Inlet pressure: up to ~3 bar

• Outlet/differential pressure: up to ~16 bar

• Viscosity range: from low to approximately 760 mm²/s (3–760 cSt)

• Smooth transfer of lubricating oils, hydraulic fluids, and other clean, non-abrasive liquids

  These characteristics enable the TRILUB TRL to support a wide range of industrial and mechanical applications without damage to pumped fluids. 

Application Examples

The Allweiler TRILUB TRL V16-40R41 is widely used for:

• Booster oil service in power generation turbines and large rotating equipment

• Lubrication systems in industrial gearboxes and heavy machinery

• Hydraulic fluid transfer in process plants

• Support duty for oil circulation in mechanical systems

  The three-screw design ensures a steady, non-pulsating oil supply — a critical factor in maintaining stable lubrication, reducing vibration, and minimizing wear on downstream components. 

Installation & Operation

This pump can be mounted in various orientations depending on system layout and space constraints. It is typically driven by an electric motor (or other prime mover) that must be properly aligned and coupled to ensure long service life and optimal performance. Correct installation ensures proper lubrication, alignment, and minimal mechanical noise. 

FAQ

What is a three-screw pump?

A three-screw pump uses three interlocking helical spindles to transfer liquids smoothly with minimal pulsation and noise, ideal for lubrication and oil pumping applications.
