CONGRATULATIONS on the purchase of a new

SDV Dry Vacuum Pump from Tuthill Vacuum &

Blower Systems. Please examine the pump for

shipping damage, and if any damage is found,

report it immediately to the carrier. If the pump is to

be installed at a later date, make sure it is stored

in a clean, dry location and rotated regularly. Make

sure covers are kept on all openings. If the pump is

stored outdoors, be sure to protect it from weather

and corrosion.

Tuthill SDV vacuum pumps are built to exacting

standards and, if properly installed and maintained,

will provide many years of reliable service. Read

and follow every step of these instructions when

installing and maintaining the pump.

WARNING

Serious injury can result from operating or

repairing this machine without rst reading

the service manual and taking adequate

safety precautions.

OTE:NRecord the pump model and serial

numbers in the OPERATING DATA form

on the inside of the back cover of this

manual. Use this identication on any

replacement part orders, or if service or

application assistance is required.

This manual provides instructions and precautions

for handling and maintenance of the Tuthill SDV

Dry Vacuum Pump. For best pump life longevity,

read this manual carefully before installing,

operating, or servicing the pump.

PRINCIPLE OF OPERATION

The SDV Dry Screw Vacuum Pump is a single-

stage, dry running, non-contact, variable-pitch

screw type vacuum pump.

The design principle of the SDV is simple. Two

parallel variable-pitch screws, having a highly

sophisticated surface prole consisting of an

Archimedean and Quimby curve and an arc, rotate

in opposite directions. Drive shaft rotation is CW

when viewed from the motor end (drive end) of

the pump. Helical-cut timing gears position these

screws relative to each other.

The pumped gas is compressed into the

discharged port by the rotation of the screws.

A specic amount of clearance for each pump

size is maintained between the two screws and

between the screws and housing, which avoids

metal-to-metal contact. The power of the motor is

transmitted to the main shaft through a coupling or

belt pulley.

Because the SDV has a variable-pitch screw

design, the compression process is more efcient

and the pump runs cooler.

For simplicity and space saving, models SDV-120

through SDV-800 are provided as standard with

anged adapters for mounting a C-ange motor

directly to the vacuum pump, eliminating the need

for a separate base frame–mounted assembly and

coupling guard for the vacuum pumps.

The power of the motor is transmitted to the drive

screw shaft through a V-pulley or a coupling,

and further transmitted to the driven screw shaft

through the timing gears.

CONSTRUCTION

Timing Gear

The timing gear is an important part of the screw

vacuum pump. The tooth surface is heat-cured

and polished with a special high-precision tooth-

polishing machine for reduced noise during pump

operation.

Bearings

The bearings on the xed side of the SDV pump

(discharge end) are angular-contact ball bearings.

The bearings on the expansion side (inlet end) are

roller bearings with heavy load capacity. These

bearings have been designed to withstand high-

speed, heavy-load service and to preserve the

clearances between gears and between screws.

Oil Level Gauge

An oil level gauge (sight glass type) is located on

the front end cover. Fill the oil to the top of the

red mark, or OL Mark. Oil levels are indicated as

follows for pumps manufactured after October

2005:

OL: Original Line (Fill oil up to this line

initially)

RH: Running High (During the Operation) –

In this case, check the pump.

RL: Running Low (During the Operation) –

In this case, check the pump.

WARNING

If the oil level is too low, gears, bearings and

mechanical seals will be damaged as a result

of improper lubrication.

If the pump were operated with low oil level,

the gears and bearings would seize by lack

of lubrications. If the oil is overlled, the oil

temperature would get elevated and cause high

gear noise and possibly affect the integrity of other

parts in the DE (Drive End) casing. When the pump

is not in use, be sure to check the oil level and

oil contamination, and then add or change the oil

when needed.

During operation, the oil is splashed over the

bearings and mechanical seals by rotation of the

timing gears.

IDENTIFICATION

Each unit has a serial number tag and a stamped

housing serial number which are both required

for correct parts identication. The housing serial

number is located on the left side of the pump

body (opposite side of the Tuthill serial number

plate) and the number is normally stamped into

the housing casting and will be a 3 or four digit

number. See examples below.
