Macawber Engineering celebrates 40 years in business. During the decades that followed Macawber Group of companies expanded to US, India, China and Brazil. All of the companies have continued to focus on dense-phase pneumatic conveying becoming highly specialist experts with the ability to convey successfully difficult to handle materials and often called to assist when other conveying m...
Orginally patented in the late 1970's, the DOME VALVE® is unique in its ability to open and close with a tight pressure seal in environment where abrasive materials are passing
We are the original designers of the Dome Valve®. The valve is uniquely designed to close and seal in a variety of extremely harsh environments; and has a proven track record of robust performance and industry acceptance.
The Macpump is a perfect choice to achieve long distance conveying at high tonnage rates, up to 300 t/h.
Flow aid devices like our Airlift®are designed improve the performance of pneumatic conveying systems by ensuring the quick and smooth filling of the conveying vessel
Macawber Group - Designed to meet your process injection requirements. The Controlveyor is capable of handling process varying back pressure to maintain an injection accuracy of 3% using a unique pressure balancing process.
Cement conveying has typically been a dirty and inefficient process through the use and misuse of screw pumps and rotary valves. This is no longer required with Macawber systems. We eliminate the need for screw pumps and the high energy requirements and maintenance they require.
Macawber provides products, engineering and maintenance services for Dense Phase Pneumatic Conveying of abrasive or fragile materials such as ash, sand, cement, foods, chemicals and more.
Originally patented in the late 1970′s, the DOME VALVE® is unique in its ability to open and close with a tight pressure seal in environment where abrasive materials are passing. No other valve can achieve as long a life in harsh environments.
Macawber Group - Switch Valves and Flow Diverters are used in Pneumatic Conveying Systems where there are more than one conveying route, reception point or a combination of the two. Keeping up with customer requirements for versatility has given us an opportunity to develop robust switch valves and flow diverters.
The Ashveyor® system is an effective low cost system for the transfer of ash or dust from a line of feed hoppers from Electro Static Precipitators (ESP) or baghouses. It is low cost and low profile and uses less energy than any other solution to multi-pickup point handling. The conveying vessel is a small casting with a heavy wall and is a simple low cost single piece item.
Macawber Group consistently delivers superior machines in terms of maintenance and our ability to handle unique materials in a gentle manner makes us uniquely qualified.
The Sandpump® is a development of the Denseveyor® low velocity dense-phase conveying system. It is a value engineered system specifically for the special needs of sand only handling systems.
The Dome Valve ® is used in a wide variety of applications in almost every process. The unique closing and sealing action of the Dome Valve® enables continuous reliable operation where conventional valves fail to perform.
The well-proven MiniDenseveyor is a low velocity dense-phase conveying system assembly that is widely used throughout all process industries in all countries of the world. Designed specifically for smaller conveying rates, utilizing a heavy-duty cast body to save material and fabrication costs.
Have you lost your best vendors?
After years of close working relationships, vendors have been swept away in the deep economic downturn. Reshaping the supply network will require new relationships and a re-examination of available quality and service. For this challenge, we provide a worldwide comprehensive resource of many types of skills and equipment at your disposal.
