RCB Asphalt High-Viscosity Pump

The RCB asphalt high-viscosity pump is designed for transferring viscous liquids that may solidify or crystallize at normal temperature but become easier to flow after heating and temperature maintenance. The pump is suitable for outdoor installation in cold regions and process systems where the medium requires heating or insulation.

The pump is available in ordinary material and cast steel material versions, both with an insulation jacket. Before startup, preheating the pump can help reduce starting power when handling viscous or solidifying media.

Structure & Working Features

The pump body of the RCB asphalt high-viscosity pump is equipped with a hollow jacket and inlet/outlet flanges for heat-transfer media. Thermal oil, steam, hot water, or similar media can be used to heat, insulate, or cool the transferred liquid and the pump.

The pump can be driven by direct motor coupling or by a reducer. When the liquid viscosity exceeds 1500 cSt, reducer drive should be used to support stable operation.

Applicable Media

The RCB asphalt high-viscosity pump is suitable for transferring corrosive or non-corrosive liquids, liquids with higher sanitary requirements, and liquids without solid particles. The medium temperature should not be higher than 350°C, and the viscosity range is 5 to 1500 cSt.

Typical media and application fields include chemical raw materials, pharmaceutical filling media, food materials, cosmetics, pesticides, detergents, printing and dyeing liquids, brewing media, resin, adhesive materials, and asphalt-related high-viscosity liquids.

Features & Advantages

• Jacketed Insulation Design: Hollow pump body jacket allows heating, heat preservation, or cooling.
• Suitable for Solidifying Media: Designed for liquids that solidify or crystallize at normal temperature and require temperature control.
• High-Temperature Media Handling: Suitable for media temperatures up to 350°C as stated in the source.
• Viscous Liquid Transfer: Suitable for liquids with viscosity from 5 to 1500 cSt.
• Flexible Drive Options: Direct coupling is available for standard conditions; reducer drive is recommended for higher-viscosity media.
• Multiple Material Versions: Ordinary material and cast steel material versions are available according to the source.
