Choosing SIRELLA SL450.R Dry Claw Vacuum Pump
The SIRELLA SL450.R is a dry claw pump for higher-throughput industrial vacuum and central systems. It provides 380 m³/h at 50 Hz or 460 m³/h at 60 Hz. Its 70 mbar end-vacuum figure is separate from the 200 mbar continuous end-vacuum limit.
Performance and operating pressure
| Specification | Details |
|---|---|
| Pumping speed, 50 / 60 Hz | 380 / 460 m³/h; PNEUROP 6602 at 20 °C |
| End vacuum | 70 mbar absolute |
| Continuous end vacuum | 200 mbar absolute |
| Electrical supply | European version: three-phase 230/400 V, 50 Hz |
| Motor power | 7.5 kW, European 50 Hz version |
| Inlet / exhaust | 3-inch BSP / 3-inch BSP, European version |
| Gearbox oil | 2 litres MB150S synthetic |
| Noise, 50 / 60 Hz | 74 / 77 dB(A) |
| Temperature sensor | PT100 included in the documented version |
| Equipment condition | New equipment, configured by quotation |
Choose the SL450.R where its larger flow capacity meets the process duty. Continuous operation is specified down to 200 mbar absolute; the lower 70 mbar end vacuum is not a continuous-duty rating. Compare the pumping-speed curve at the working pressure and account for line conductance, leakage and simultaneous demand.
Dry compression and installation
Contactless claws keep sealing oil out of the pumping chamber. The gearbox still requires the specified lubricant and maintenance. Plan inlet filtration, exhaust routing, motor starting and cooling clearance for the actual process. The PT100 sensor is included in the documented pump; a complete starter panel and process controller are not implied.
UK configuration
| Specification | Details |
|---|---|
| 824523 | European pump: three-phase 230/400 V, 50 Hz, 7.5 kW, 3-inch BSP connections |
The European reference supports a three-phase 400 V, 50 Hz installation when connected for that supply. Confirm the motor nameplate, protection and starter with the quotation. Other regional versions have different supply and connection specifications; this model-level listing has no single configuration-specific part number.
Accessories and servicing
The sheet lists a type 301 suction filter with paper, polyester or carbon cartridge choices, a constant-vacuum solenoid valve, a vacuum gauge and direct starters as options. Select these for the gas stream and control requirements rather than assuming they are all included. The listed usual-maintenance kit is 725291 and preventive kit 725292; confirm the schedule and compatibility against the supplied pump.
