Model 969-8903 with ConFlat 4.5" external diameter high vacuum
flange;

vacuum flange.
Pump Description
The pump consists of a high frequency motor driving a turbine fitted
with 9 bladed stages and 3 Macrotorr stages. The turbine rotates in
an anticlockwise direction when viewed from the high vacuum flange
end.
The turbine is made of high-strength aluminium alloy, machined from
a single block.
