CODE 3619-001-25579857-2001
Applied in pumps units and equipment for neutral and non-toxic mediums.
The mechanical seals of the second type of construction can be used in the cases when there can be an obstruction of the holes and springs with abrasive particles, sedimentations of working liquids and so on.
| Shaft diameter, mm | from 18 to 250 |
| Shaft rotation speed, rpm | from 30 to 7500 |
| Temperature of sealed medium, °C | from -60 to 150* |
| Pressure of sealed medium, MPa | from 0,1 to 10 |
| Maximum leakage, l/h | 0,002 |
*The maximum temperature of sealed water is 85 °C
Applied in trunk line pumps where sealed fluid is oil and oil products.
Protective step prevents leakage of pumped fluid into atmosphere and participate in transferring of shut-off signal in case of main sealing disclosure.
| Shaft diameter, mm | 24...140 |
| Shaft rotation speed, rpm | 30…4000 |
| Temperature of sealed medium, °C | -15… 50 |
| Pressure of sealed medium, MPa | 0,1 ... 10 |
| Maximum leakage, l/h | 0,050 |
CODE 3619-001-25579857-2001
They can be used in pumps and aggregates pumping water at temperature more than 85°C.
The boiling of water is excluded directly in the pair of friction.
| Shaft diameter, mm | from 18 to 250 |
| Shaft rotation speed, rpm | from 30 to 7500 |
| Temperature of sealed medium, °C | from 85 to 130 |
| Pressure of sealed medium, MPa | from 0,1 to 10 |
| Maximum leakage, l/h | 0,002 |
| Pumped medium | boiler water, mains water |
CODE 3619-008-25579857-2014
The mechanical seals can be used in deadwood propellers shafts of the vessel at large radial and angular movements (up to 6 mm) of the shaft at the location of the seal.
It provides the tightness of the shaft while disassembling and repair because of the original construction of the parking seal.
