Primary Application
This BZK80 vacuum pump is designed to remove air from prestressed ducts before grouting, ensuring full and compact cementitious filling in bridge and concrete construction projects. It is an essential tool for preventing voids and improving the durability of prestressed structures.
Technical Specifications
The pump delivers a maximum airflow of 80m³/h and achieves an ultimate vacuum pressure of 0.097Mpa, meeting the deaeration requirements for most standard prestressed duct sizes. Powered by a 2.2kW motor running at 2850rpm, it ensures stable and continuous operation. The working fluid flow rate is 2.5L/min, supporting consistent vacuum generation throughout the grouting preparation process.
Operational Features
With a noise level of only 66dB(a), the pump operates quietly to minimize disturbance on construction sites. Its compact, enclosed design with built-in casters ensures easy movement between work areas. The unit weighs just 70kg, offering a good balance of stability and portability for both indoor and outdoor applications.
Performance Benefits
This vacuum pump provides reliable, efficient air removal, helping to eliminate air pockets and improve grout penetration. Its low-noise design and compact footprint make it suitable for various construction environments. Built for durability and minimal maintenance, it ensures consistent performance over long periods of use, contributing to the overall quality and safety of prestressed construction projects.
