Diaphragm Pump
The diaphragm pump uses a membrane to separate the liquid being transported from components such as the pump cylinder, so as to prevent the components from being eroded, leaking of the liquid to be transported, environmental pollution and personal safety accident.
The diaphragm pump operates at an efficiency of 82-87% and the transport medium has a weight concentration of up to 75%, which saves water resources. Meanwhile, the discharge pressure of the diaphragm pump is as high as 25MPa, it can realize high-concentration medium transportation at a long distance, reduce the number of pumping stations, and greatly reduce engineering investment costs. In addition, this equipment consumes less power and saves operating costs by more than 50% compared to other traditional diaphragm pumps.
- Mine: Long distance discharge for gold, silver, copper, iron, zinc and other tailings;
- Coal and chemical industry: Conveying high concentration coal water slurry;
- Alumina: Conveying high-temperature aluminum ore pulp, red mud, etc.;
- Coal transportation through pipeline.
