ALLWEILER TRILUB TRL V16-40R41 Screw Pump Complete

Overview

The Allweiler TRILUB TRL V16-40R41 is a three-screw positive-displacement pump built for smooth, low-pulsation delivery of lubricating and hydraulic fluids in engines, gearboxes, turbines, and other rotating machinery. Its three-spindle screw design produces continuous, near-pulsation-free flow, which matters for lubrication and hydraulic circuits where flow spikes can disturb sensitive downstream components or bearings.

As part of Allweiler’s established TRILUB screw pump range (a CIRCOR brand), the TRL series covers low-pressure lubrication and hydraulic supply duty across a wide range of fluid viscosities. Seven Star LLC supplies the Allweiler TRILUB TRL V16-40R41 complete pump unit as a trusted Allweiler/CIRCOR parts supplier to marine, power generation, and industrial facilities across Oman and the GCC.

Operating Principle

The TRL pump uses three intermeshing screw spindles — one power rotor driven by the motor and two idler rotors — that trap fluid in sealed cavities formed between the screw threads and pump housing, moving it axially from inlet to outlet with each rotation. Because multiple sealed cavities are always in motion simultaneously, the pump delivers continuous, smooth flow without the pulsation pulses that gear or piston pumps can introduce, protecting sensitive lubrication and hydraulic circuits from pressure ripple.

Engineering Design of the Allweiler TRILUB TRL V16-40R41

The TRL series delivers flow rates up to 880 L/min depending on model size, with inlet pressure capability up to 3 bar and outlet pressure up to 16 bar. It handles a wide wide viscosity range (see manufacturer catalog), covering thin hydraulic oils through heavier lubricants, and operates within the fluid temperature limits stated in the manufacturer catalog. The V16-40R41 designation identifies the specific size and configuration variant within the TRL family, matched to a particular flow and pressure duty point for the original application.

Industrial Applications

The TRILUB TRL V16-40R41 is used for lubrication oil supply and hydraulic power circuits on engines, gearboxes, and turbines in power generation, marine, and heavy industrial facilities across Muscat, Sohar, and Salalah, where continuous, low-pulsation flow protects bearing surfaces and hydraulic actuators from flow-related stress. Its wide viscosity range makes it adaptable across different lubricant grades and operating temperatures.

Across the GCC’s marine, power generation, and heavy machinery sectors, the TRL series is commonly specified as an OEM or replacement pump for turbine lubrication systems, gearbox oil circulation, and hydraulic power units where a screw pump’s smooth flow characteristics and durability under continuous duty are valued over the simplicity of a gear pump.

Allweiler TRILUB TRL Selection Notes

The Allweiler technical data sheet describes the TRILUB TRL as a three-screw pump for duties up to 16 bar, intended for lubricating liquids that contain no abrasive particles, mainly lube oils, hydraulic oils and light fuel oils. The liquid must not chemically attack the pump materials, so fluid compatibility should be confirmed before the pump is used on anything other than clean mineral oil.

The published limits are for the series as a whole, not for one size. They are a capacity of up to 880 l/min, inlet pressure up to 3 bar, discharge and differential pressure up to 16 bar and a speed of up to 3600 rpm. The actual flow of a given pump depends on its size and on speed and viscosity, and has to be taken from the nameplate or the order documentation.

The series is self-priming, has a shaft seal, and can be installed vertically or horizontally. Listed arrangements include bulkhead and pedestal mounting, dry installation, and submerged or in-tank installation. The installed nameplate data should be quoted when a replacement is requested.
