The LQB series insulated gear pump is suitable for transferring non-corrosive media that contain no solid particles and may solidify at normal temperature. It is especially suitable for outdoor installation in cold regions and process systems where the transferred medium needs to be heated or insulated.
The pump is suitable for media temperatures up to 250°C and viscosity from 5 to 1500 cSt. Typical media include heavy oil, asphalt, adhesive materials, resin, detergent, and similar liquids.
Structure & Working Features
The pump body of the LQB series insulated gear 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 body.
This jacketed structure helps maintain the medium at a suitable temperature during transfer, improving flowability for materials that become viscous or solidify at normal temperature.
Features & Advantages
- Insulated Jacket Design: Hollow pump body jacket allows heating, heat preservation, or cooling.
- Suitable for Solidifying Media: Designed for asphalt and similar media that may solidify at normal temperature.
- Viscous Liquid Transfer: Suitable for heavy oil, asphalt, adhesive, resin, detergent, and similar non-corrosive liquids.
- Cold-Region Installation: Applicable to outdoor installation in cold areas where insulation is required.
- Temperature-Controlled Pumping: Thermal oil, steam, or hot water can help maintain suitable flow conditions.
- Process Compatibility: Suitable for applications where the medium must remain warm during transfer.
Typical Applications
- Asphalt transfer
- Heavy oil transfer
- Adhesive and resin transfer
- Detergent transfer
- Temperature-controlled process transfer
- Outdoor installations in cold regions
- Heating or insulation systems for viscous liquids
