The LG series stainless steel rotary lobe pump operates using two three-lobe impellers mounted on parallel shafts. As the impellers rotate at a constant speed in opposite directions, they maintain a microscopic clearance with the inner surface of the elliptical casing and with each other. This counter-rotation creates a volume change that transports a specific amount of gas from the suction side to the discharge side without internal compression. Synchronizing gears keep the impellers in the exact phase, eliminating any internal friction or collision. Because there is no mechanical contact inside the casing, internal lubrication is completely unnecessary, ensuring that the discharged gas is 100% oil-free. This makes it an ideal pneumatic conveying source for industries with strict purity requirements.
The LG series stainless steel rotary lobe pump is widely utilized across industries such as chemical fertilizer production, blast furnace smelting, petrochemicals, food processing, and instrumentation. It excels in applications including vacuum dehydration, backwashing, forced draft ventilation, exhaust, and drying. Manufactured with high precision, Longgu dry rotary lobe pumps offer an excellent balance of cost-effectiveness, superior technology, and long-lasting stable performance.
Features & Advantages
The LG series stainless steel rotary lobe pump is composed of a robust casing, wall plates, three-lobe impellers, precision timing gears, heavy-duty bearings, mechanical seals, V-belt drives or direct couplings, and safety accessories like pressure relief valves. For noise-sensitive environments, custom inlet/outlet silencers or acoustic enclosures can be seamlessly integrated. Key features include:
- Oil-Free Delivery: Frictionless internal operation guarantees completely oil-free air or gas discharge, critical for chemical and food-grade applications.
- Low Noise & Low Pulsation: The optimized three-lobe rotor design minimizes gas pulsation, significantly reducing blower noise and operational vibration.
- High Efficiency & Durability: Advanced machining ensures tight tolerances. The lack of internal wear parts translates to a long service life and continuous, stable operation at high speeds.
- Easy Maintenance: Featuring specialized bearings and a compact, straightforward design, the pump requires minimal upkeep and offers quick startup times.
- Versatile Applications: Highly adaptable for both vacuum and pressure applications, easily handling challenging industrial environments.
