Pump systems an outside job

摘要

Hidrostal says pump mixing systems have distinct advantages over conventional mixing systems because, instead of being an in-tank solution, the pump is mounted externally at ground level. The company says: "By mounting the pump outside the tank, maintenance problems -normally associated with the more traditional methods - are eliminated. This is because there are no moving parts within the tank. It is easily accessible for installation, inspection and maintenance." Hidrostal says the advantages of externally mounted pump mixing systems include: 1. The mixing energy is provided by an externally mounted pump, and no moving parts are required in the tank 2. No requirement for high-level lifting equipment. Access platforms can be fitted to new and existing tanks 3. Large-diameter pipework and nozzles for effective solids handling 4. Tank/digester turnover and nozzle energy can be selected to suit sludge characteristics and tank shape.
