The DPL-V300B is an oil-sealed single-stage rotary vane pump. At 50Hz, nominal pumping speed is 280 m³/h and pumping speed is 240 m³/h. Motor power is 5.5 kW, three-phase 230V / 400V ±10%, motor speed 1500 r/min. The unit weighs 223 kg (with oil) and measures 1090 × 555 × 450 mm. The inlet is a G2″ flange connection.
Ultimate pressure is ≤8×10⁻² mbar with gas ballast closed and ≤0.7 mbar with gas ballast open. Oil capacity is 8.5 / 11.5 L, noise level is 72 dB(A), ambient operating temperature is 0 ℃ to 40 ℃, and ambient pressure must not exceed standard atmospheric pressure.
This model is used in metallurgy, machinery, electronics, chemical processing, food preservation, coating, refrigeration, freeze-drying, helium leak detection, petroleum, and pharmaceutical production and research departments. It is also commonly used as the backing pump for Roots pump systems.
Set the gas ballast valve opening according to the moisture content of the process gas. Confirm before ordering if 60Hz or a special voltage is required.
Pumping speed, connections, voltage, and accessory configuration can be adjusted according to the ordered application. Technical parameters are subject to the product documentation. Before selection, send us your pumping speed requirements, target vacuum level, gas type, and site voltage for confirmation.
