Product Description The oil-free vacuum pump consists of a pump head, a motor, and a base. The pump head includes dynamic and fixed scrolls, a crankshaft, seals, a fan, and a pump housing. The scrolls are composed of a circular plane and one or several spiral walls extending from it in the form of an involute curve. The fixed scroll and the dynamic scroll together form the scroll pair, which constitutes the basic pumping mechanism of the oil-free scroll vacuum pump. During operation, the dynamic and fixed scrolls do not contact each other but rely on relative motion to create continuously shrinking crescent-shaped suction and compression chambers. Through the cycle of suction, compression, and exhaust, gas is drawn in from the suction port and expelled through the exhaust port, achieving vacuum pumping in the target chamber.ParameterUnitValue 1Value 2Value 3Value 4Pumping Speedl/s16.68.74.32.0 l/min996.0522.0258.0120.0 m3/h59.831.315.57.2 cfm35.818.79.34.3Ultimate VacuumPa≤1.0≤1.0≤2.6≤8.0 Torr≤7.5×103≤7.5×103≤1.9×102≤6.0×102 mbar≤1.0×102≤1.0×102≤2.6×102≤8.0×102 psi≤1.4×10≤1.4×10≤3.8×10≤1.2×103Noise LeveldB(A)≤63≤63≤63≤57Leak Rate (Exhaust & Gas Ballast Closed)Pa·m3/s1×10---Max.

It utilizes high-temperature-resistant seals and imported high-temperature pump oil, making it more suitable for high-temperature environments such as vacuum tube furnaces.The pump is equipped with imported original oil seals, ensuring reliable long-term sealing performance. Its integrated body design minimizes the number of components, improves repeatability, and offers a compact structure for easy maintenance and repair.Additionally, the pump incorporates a built-in gear pump and a constant-pressure oil supply mechanism for forced lubrication, ensuring stable and reliable operation even under high suction pressure. An automatic anti-backflow valve effectively protects your vacuum system from oil contamination after shutdown.This product also features a two-stage gas ballast function, allowing adjustment to meet different process requirements for vapor exhaust capacity.Technical NameTechnical ParameterPumping Speed50Hz: 65 m3/h (18 L/s) 60Hz: 78 m3/h (21.6 L/s)Ultimate Partial Pressure (without gas ballast)4×102 PaUltimate Total Pressure (without gas ballast)4×101 PaUltimate Total Pressure (with gas ballast)8×101 PaPower Supply3-phaseMotor Power2.2 kWInlet/Outlet ConnectionDN KF40Oil Capacity3.3-4.5 LMotor Speed50Hz: 1440 rpm 60Hz: 1720 rpmOperating Ambient Temperature5-40°CNoise Level≤62 dBWeight65 kgThis pump is a direct-drive rotary vane mechanical vacuum pump with the following features:Compact size, lightweight design, and easy startup for convenient operation.Equipped with a noise reduction device, ensuring low mechanical noise during operation.Built-in anti-backflow protection, preventing vacuum pump oil from being sucked back into the pipeline, while also enabling easy restart.Includes a gas ballast valve to effectively eliminate water vapor.Oil mist trap installed at the exhaust port, preventing contamination of the experimental workspace.Powered by a single-phase motor, offering convenient power supply compatibility.ModelPumping Speed (L/S)Ultimate Partial Pressure (Pa)Rotation Speed (r.p.m)Motor Power (Kw)Inlet Diameter (mm)Oil Temperature Rise (°C)Oil Capacity (L)Weight (Kg)Noise (dB)RJ-2XZ0.250.25≤6×10114000.126.5/10≥400.311<60RJ-2XZ0.50.5≤6×10214000.186.5/13≥400.4213<60RJ-2XZS11-14000.256.5/18≥400.4218<60RJ-2XZS22-14000.376.5/13/25≥450.4825<65RJ-2XZS44-14000.556.5/13/25≥450.5527<65RJ-2XZS66-14100.7525≥500.640<67RJ-2XZS88-14101.140≥550.755<70RJ-2XZ1515-14101.540≥550.865<70
