Industrial Vacuum Pump System

Our Industrial Vacuum Pump System is a large Roots vacuum pump. It works on the same principle as the LC250 and LC500. Two figure-eight rotors turn in opposite directions. They do not touch metal surfaces. The seal comes from a small gap. The difference is the size. This pump is much larger. The inlet uses ISO160. The outlet uses ISO100. The pump weighs 149 kg. The body has reinforcement ribs for better rigidity. Large flow creates strong air impact. Without good rigidity, the pump body can deform slightly. That changes the rotor gap. The gap gets larger and the pumping speed drops. Our machining equipment and rigid design keep the gap stable for years. This model has a three-chamber independent lubrication system. The oil seal, gearbox, and gear case each have their own oil chamber. They do not connect. The oil seal holds 0.125 L. The gearbox holds 2.4 L. The gear case holds 1.25 L. We fill all three before shipping. Dongguan DaluTong has been manufacturing Roots pumps since 2015. We completed mass production of the full LC series that same year. We are a recognized supplier of industrial vacuum systems in China. We have completed more than 100 custom vacuum station projects.

Our Industrial Vacuum Pump System uses three separate oil chambers. This design helps with long-term operation. Large pumps put more stress on the gears. Minor wear happens over time. The tiny metal particles stay in the gear case oil. They do not flow into the gearbox or oil seal. The gearbox oil stays clean. The oil seal lubrication stays pure. When you do maintenance, you only service the chamber that needs work. You do not have to take the whole pump apart. Our full LC series includes the LC250, LC500, LC1200, LC2600, and LC4200. The LC1200 is the middle model in this range. We offer larger models up to 4200 m³/h. We also offer smaller ones. We can put together a complete system for you. We do not just sell individual pumps. We take on complete pump sets and vacuum station projects. All machining is done in our own factory using Mazak equipment. This gives us full control over quality and delivery.

This Industrial Vacuum Pump System is built for large industrial applications. Large central vacuum stations, metallurgy vacuum degassing units, power industry auxiliary systems, and chemical distillation columns all use this pump. These places share common needs: high flow, long running hours, and complex systems. Small pumps cannot handle these conditions. The most common setup pairs this pump with rotary vane pumps. One or two DLT.V0302 or V300B pumps do the rough work. Two or three LC1200 units in parallel boost the total speed. The total pumping speed reaches several thousand m³ per hour. That is enough for a whole production line or even an entire workshop.
