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. 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 f iring, hydraulics, mechanical engineering, general industrial technologies, chemical and petrochemical industries, marine and offshore engineering, lube oil applications. Bearing Designs — Either internal medium lubricated groove ball bearing or external grease lubricated and re-greaseable groove ball bearing. Shaft Seal — Unheated, uncooled mechanical seal no other options available. Drive Installation — Close coupled installation only horizontal foot mount or vertical tank mount.
