No. ZK2-OM01301
11.2. Vacuum Pump System Flow Rate Characteristics
The graph shows the suction flow rate characteristics of the vacuum pump system at different vacuum
pressure.
■ZK2P00
The actual suction flow at the point of suction varies depending on the piping conditions to the vacuum port.
(The above graph shows the value when V port is ø8.)
11.3. Vacuum Release Flow Rate Characteristics
The graph shows the flow rate characteristics at different supply pressures when the vacuum break flow
adjusting needle is open from the fully closed state.
■ZK2□□□ (Ejector)
The actual suction flow at the point of suction varies depending on the piping conditions to the vacuum port.
(The above graph shows the value of the ZK2B07)
