The LC Roots pump is suitable for transferring crude oil, petroleum products, syrup, yeast slurry, and mildly alkaline liquids with medium temperature not higher than 140°C. It is used in petroleum, food processing, and related industrial applications.
The pump is available in two drive forms: belt drive and gear reducer drive. It features low rotational speed, good efficiency, compact size, large flow capacity, low power consumption, good self-priming capability, no need for priming oil, and convenient operation.
It can be used for transferring petroleum and petroleum products, as well as factory liquid media 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 transfer liquids such as soybean milk, yeast slurry, and syrup when the selected material configuration is suitable. It is also suitable for loading and unloading oil tank trucks and oil tankers, with convenient operation and reversible transfer capability.
Structure & Working Features
The LC Roots pump consists of the pump body, pump cover, shaft, gears, rotors, packing, gland, and related components. The pump can be driven by belt transmission or gear reducer transmission and can operate in reverse direction when required by the process.
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.
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 pump working chamber, supporting continuous or intermittent operation under suitable conditions.
Features & Advantages
- Low-Speed Operation: Supports stable liquid transfer with low rotational speed.
- Large Flow Capacity: Suitable for oil transfer, loading, unloading, and process circulation.
- Self-Priming Capability: Can operate without priming oil under suitable conditions.
- Reversible Operation: Supports forward and reverse transfer for flexible loading and unloading.
- Drive Flexibility: Belt drive and gear reducer drive options are available.
- Optional Insulation Structure: Jacketed or insulated configuration can be selected for asphalt, condensate oil, or heat-preserved media.
- Convenient Maintenance: Simple structure supports practical operation and service.

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.
