TS EN 12845 + A2 (2012) standard is exactly the same as the EN 12845 + A2 (2009) standard, and it is the first “Turkish Fire Standard” to be established by the Turkish Standards Institute (TSE) with the permission of the European Committee for Standardization (CEN).
This standard was established based on the EN 12845 + A2 (2009) standard that is accepted by CEN, prepared by the TSE Engineering Services Expertise Group, and accepted and issued as a “Turkish Standard” at the TSE Technical Council meeting on July 19, 2012.
PUMP FEATURES
| Pump Body | Back pull-out design |
| Pump Body Material | GGG25, GGG40 or AISI304 |
| Shaft | AISI316 |
| Sealing | Mechanical seal or soft packing (5 row) |
| Coupling Connection | Spacer coupling |
| Impeller | GGG25, AISI304 or bronze |
TECHNICAL FEATURES
| Closed Valve Pressure | 125% of the nominal pressure |
| Maximum Load | The pressure when the flow rate increases to 140% should not be less than 70% of the nominal pressure |
| Back Up | In two-pump systems, each pump should ensure predefined flow rate and pressure alone. It can be selected in a manner to cover 50% of each pump’s nominal flow rate on the systems with three pumps |
| Suction Line Water Flow Rate | Flow rate is 1.8m/s in positive suction and 1.5 m/s in negative suction |
