The Allweiler TRILUB range offer low-pressure Screw Pumps for lubricating liquids. Whenever machines, motors, gear sets or turbines must be supplied with lubricating oil; when hydraulic units must have a certain oil pressure; when oil must be transferred in power plants, refineries and tank farms; or when industrial burners must be supplied with light or heavy fuel oil – triple-spindle, low-pressure Screw Pumps are right at home in all of these situations and many more.
Allweiler TRILUB Series Triple Screw Pumps
- Best for Lubricating Fluids
- Used extensively in Power Plants, Refineries and Tank Farms
- Five series for optimal performance throughout flow/pressure range
For handling lubricating liquids with no abrasive substances, no chemical attack of pump materials, in particular lube oils, hydraulic oils and light fuel oils in all industrial fields of application. The TRD range are typically used in firing, hydraulics, mechanical engineering, general industrial technologies, chemical and petrochemical industries, marine and offshore engineering, lube oil applications.
