The LC reducer Roots pump is a positive displacement rotary pump used for transferring petroleum products, asphalt, condensate oil, and various industrial liquids. It is available with belt drive and gear reducer drive, and it can operate in forward or reverse direction.
The pump is suitable for transferring petroleum and petroleum products, as well as oil and liquid media used in factories, such as crude oil, paint, lubricating oil, glass adhesive, grease acid, toothpaste, and mildly alkaline liquids used in soap processing. In food processing, it can also be used for transferring liquids such as soybean milk, yeast slurry, and syrup when the selected material configuration is suitable.
For gasoline service, the source text states that copper pump blades can be selected. This requirement should be specified when ordering.
Structure & Working Features
The LC reducer Roots pump consists of the pump body, pump cover, shaft, gears, rotors, packing, gland, and related components. Oil-resistant framework seals are installed at both shaft ends, and an oil return device is installed in the middle to help prevent air intake or oil leakage.
The pump features low speed, good efficiency, compact size, large flow capacity, low power consumption, good self-priming capability, no need for priming oil, and convenient operation.
For asphalt and condensate oil transfer, an insulation layer can be added to the pump casing or end cover. Steam or thermal oil circulation can be used to insulate the working chamber, supporting continuous or intermittent operation under suitable process conditions.
Features & Advantages
- Low-Speed Operation: Designed for stable transfer with low rotational speed.
- Large Flow Capacity: Suitable for loading, unloading, and transferring oil tanks, tank trucks, and oil tankers.
- Self-Priming Capability: Can operate without priming oil under suitable conditions.
- Reversible Operation: Supports forward and reverse operation for flexible transfer requirements.
- Drive Flexibility: Available with belt drive or gear reducer drive.
- Optional Insulation Jacket: Can be configured for asphalt, condensate oil, or other media requiring heat preservation.
- Wide Media Compatibility: Suitable for petroleum products, oils, paint, grease, toothpaste, mildly alkaline liquids, soybean milk, yeast slurry, syrup, and similar liquids.

Ordering Notes
Pumps with flow rates above 18 m³/h can be supplied with an insulation jacket. When ordering an insulated version, add W to the model code, such as LCAW50/0.6.
Pump rotors or blades can be made of copper for different models. When ordering a copper configuration, add T to the model code, such as LCAT50/0.6. If T is not added, the pump is supplied with the normal standard material.
When the medium temperature is higher than 120°C, the medium temperature should be specified when ordering.
