Air Operated Pump
Air Operated Pump and its purpose
The ODS pump is mainly used for the slurry material which is thick in nature. The ODS pump assembly consist of a Diaphragm & pump casing in the centre, 3-way solenoid valve at the top and a ball check valve at the bottom. The diaphragm pump is operated by air.
The ODS pump so designed can work with pressure up to approx. 7 kg/cm2 handling a great variety of slurries and solutions both hot & cold, acidic & alkaline and abrasive too. The advantage of ODS pump is it operate without leakage and no mechanical linkage is required for transmitting force to the diaphragm.
Working principle of ODS Pump:
The ODS pump is a positive displacement pump that uses compressed air as its power source. Compressed air is transferred from one chamber to another by a connected shaft, allowing the chambers to move simultaneously. This back-and-forth movement forces liquid from one chamber into the discharge pipe while the other chamber is filled with liquid. Diaphragm pumps can convey low, medium and high viscosity liquids, but also can convey a large solids content of the liquid.
Advantages of ODS Pump:
- Run-Dry Capability—The ODS can operate dry for an indefinite period. No seal can fail, no stator that will burn out, and no air binding.
- Seal less Design—There is no seal in the ODS design, allowing leak-free operation while preventing outside contaminants from infiltrating the process slurry.
- Simple Maintenance—Once installed and running properly, the pump requires minimal maintenance and monitoring. This makes it cost-effective to operate and simple to maintain.
- Adjustability—Seamlessly adjust the ODS Pump during operation for capacity and discharge pressure, keeping it optimized despite changing conditions.
Industrial Application of ODS Pump:
- Sand and Aggregate
- Mine and Minerals
- Waste water treatment
- Coal and Power Plant
- Steel and Metallurgical Plant
