STP Series Turbomolecular Pump 
 
INSTALLATION OF THE STP PUMP
 
 
2.1.3  Bench 
A bench must be prepared by the customer to secure the STP pump. The shape and size of the 
bench differ depending upon the type of STP pump. (see "HOW TO SECURE THE STP PUMP" in 
the STP Pump Instruction Manual (B)) 
WARNING 
 
Obey the safety instructions given below and take note of appropriate precautions. 
If you do not, you can cause injury to people and damage to equipment. 
WARNING 
 
The STP pump is provided with a high-speed rotor. Any internal abnormality/error 
may result in a jump in rotational torque leading to personal injury or peripheral 
equipment damage. 
WARNING 
 
Design and secure the bench for the STP pump so that it can withstand the 
maximum torque generated due to the occurrence of an abnormality/error. Refer to 
"HOW TO SECURE THE STP PUMP" in the STP Pump Instruction Manual (B) for 
abnormal torque. 
CAUTION 
 
Secure the customer-prepared bench and the vacuum equipment on the floor or peripheral 
equipment and other equipment in accordance with the customer application. NEVER move them 
while the STP pump is in operation. 
 
Confirm the dimensions by the external appearance of the STP pump when designing the bench. 
The bolt may not be able to be inserted from the lower side of the inlet port according to the shape of 
the inlet port flange. 
Note:  When the external appearance of the STP pump is not in the manual, contact Edwards.
