The Danfoss PAH / PAHT pump product programme, covering tap water and technical water operation, is also available ATEX “certified”.
The pumps can be used in Category 2 (Zone1, 21) and Category 3 (Zone2, 22) classified areas. The pump temperature class is T6 < 85°C. Operational and physical data can be found in the respective pump data sheets.
Validity:
Approvals are only related to water as fluid. Other fluids, if any, must be non-flammable and comply with standard EN 13463-5 § 7.5.5. The pumps are designed to pump liquids and not gases! It is the user’s responsibility to ensure that the pump is filled with fluid.
Fluids:
If the pump is to operate on other fluids than water, please contact Danfoss. Other operation and maintenance conditions might apply.
Minimum suction pressure:
The user must always ensure that the pump is filled with the fluid to be pumped. The pumps must always be operated with a “positive head” on suction port. The minimum and maximum allowable inlet pressure for the suction port can be found in the pump data sheet.
Maximum discharge pressure:
It is the user’s responsibility to ensure that the pump discharge pressure does not exceed the max continuous discharge pressure + 10% stated in the pump data sheet.
Temperature:
The pump is not to be used in systems where the fluid temperature exceeds 50°C /122°F.
Filtration:
Fluids to be used in the pump must as a minimum always be filtered according to the specification found in the pump data sheet.
External impacts due to: Gases:
The pumps are made of materials resistant to most common gases. The user of the pump must ensure that materials used are resistant to the gases applied.
Dust:
The pumps may be used in “Dust Certified Areas “– but the pump housing must be cleaned regularly and always when the dust layer is exceeding 5 mm (0.2 inch). It is the user’s responsibility that the dust generated in the area of operation is compatible with the materials applied for the pump.
