INTRODUCTION PRINCIPLE OF OPERATION CONGRATULATIONS on the purchase of a new SDV Dry Vacuum Pump from Tuthill Vacuum & Blower Systems. Please examine the pump for The SDV Dry Screw Vacuum Pump is a single- shipping damage, and if any damage is found, stage, dry running, non-contact, variable-pitch report it immediately to the carrier. -
Page 8: Construction
Introduction CONSTRUCTION If the pump were operated with low oil level, the gears and bearings would seize by lack of lubrications. If the oil is overfilled, the oil Timing Gear temperature would get elevated and cause high gear noise and possibly affect the integrity of other The timing gear is an important part of the screw parts in the DE (Drive End) casing. -

Piping AIR-WATER RADIATOR This system is an air-cooled version with a cooling water total recovery system. A centrifugal pump circulates the cooling water from the SDV vacuum pump to a radiator-fan unit. To monitor the adequacy of the cooling water flow and the cooling water discharge temperature, install a flow indicator, flow switch on the cooling water supply line and a temperature gauge (or switch) at the cooling water discharge line. -
