SCREWLINE SP 630 3Ph 200/400 V 50 Hz; O2 version, purge gas unit, electromagnetic gas ballast

Leybold SCREWLINE SP 630 – dry screw pump with air cooling

The SCREWLINE SP 630 reaches an effective pumping speed of 630 m³/h at 50 and at 60 Hz and an ultimate pressure of ≤ 0.01 mbar. The nominal power is 15 kW; at ultimate pressure the pump draws less than 11 kW. It measures 1630 × 660 × 880 mm (W × D × H) and weighs approx. 530 kg; the noise level is ≤ 72 dB(A), measured with connected exhaust line at ultimate pressure. The SP 630 is air-cooled; with water cooling it is called SCREWLINE SP 630 F.

Design

Two counter-rotating screw rotors that run without contact convey the gas on a direct path from the inlet to the outlet; according to Leybold this makes the pump insensitive to foreign materials. The rotors have a cantilevered bearing arrangement: there is no bearing on the intake side, so no lubricant from the bearings can enter the process and no aggressive process medium can attack the bearings. The pump housing can be removed without dismantling the bearings – the surfaces in contact with the medium can be cleaned on site. According to Leybold, a temperature of at most 100 °C is reached inside the pump, which avoids deposits of temperature-sensitive substances. The two non-contacting shaft seals are practically wear-free; all pumps have a purge gas unit and the SP-GUARD monitoring system.
