ALLWEILER TRILUB TRL — Three-screw pump — Product series
ALLWEILER TRILUB TRL is a three-screw pump family for lubricating and hydraulic oils. Its self-priming, low-pulsation pumping principle is suited to oil circulation and supply duties where steady delivery is required.
Send the complete model, item number, quantity and nameplate photograph. DFIN will confirm the configuration, supply scope and lead time.

SELECTION AND SERVICE
Configuration and operating conditions
The clean liquid must provide the lubrication required by the screw set and remain compatible with the selected casing, screws, shaft seal and elastomers.
State operating viscosity and temperature, inlet pressure, required flow and differential pressure. Include the mounting, connection and pressure-relief arrangement from the existing installation.
The CIRCOR series table lists the maximum envelope. Its maximum flow, pressure, viscosity and temperature are not necessarily simultaneous.
- Use the complete size and execution code to identify the screw set, casing or liner, bearings, mechanical seal, relief-valve components and gaskets.
- For an installed TRL, provide the full nameplate, serial number and sectional-drawing positions rather than ordering from the family name.
- Use the complete nameplate designation, serial number and component item number to confirm the equipment revision and fit.
- Check the fluid, temperature, viscosity, required flow, pressure, suction conditions and connection standard for the actual application.
- Confirm all wetted materials, seals, diaphragms and other selected components against the operating conditions. A material name alone does not establish suitability.
- For replacement parts, include photographs of the old part, its assembly position and relevant dimensions.
