Specifications:
The document provides detailed specifications for the Oil-Sealed Rotary Vacuum Pump GHD-031 by ULVAC KIKO, Inc. The pump operates at different frequencies (50Hz and 60Hz) with actual pumping speeds of 30 L/min and 36 L/min respectively. The ultimate pressure with the gas ballast valve (G.V.) closed is 0.67 Pa, 5.0 × 10^-3 Torr, or 6.7 × 10^-3 mbar. The motor is single-phase, operating at 200-240V with a full load current ranging from 0.84 to 1.03 A. The oil capacity is 370 mL, and the recommended oil type is R-2. The pump weighs 9.3 kg and has an inlet port diameter of KF-16. It operates within an ambient temperature range of 7 – 40°C (44.6 – 104°F) and has overall dimensions of 120(W) × 288.5(L) × 163(H) mm.

Features:
The pump features a wide range voltage motor compliant with CE and cTUVus standards. It includes a magnet coupling to prevent oil leakage and extend the pump's lifetime. An integrated check valve below the inlet port prevents backflow. The pump is equipped with a helium leak detector.

Applications:
The pump is suitable for use in analytical equipment such as GC/MS, ICP/MS, LC/MS, and laboratory experiments.
