CAPACITY RANGE
Casing Pressure:Cast-iron casings
at temperatures up to 120°C 10 ats. gaugeat temperatures exceeding 120°C up to 140°C 8 ats. gauge
For higher pressures; attention is drawn to design in S.G. cast iron.
Maximum Peripheral Speed:
For cast iron impellers 40 m/sec (131 ft/sec) (diameter in metres x R.P.M. x 3,14) 60
Use cast chrome-steel or bronze, for higher peripheral speeds.
Temperature:
Maximum operating temperature for all sizes:
with standard stuffing box N 105°C (uncooled stuffing box)with hot water stuffing box HW 140°C (cooled stuffing box)
For higher temperatures, refer to S.G. cast iron construction.
Lubrication:
The pump shaft runs in two oil-lubricated ball-bearings.The bearings and the bearing bracket should be flushed with petrol or benzene while slowly rotating the shaft. After cleaning and complete removal of the cleaning agent, the bearing bracket should be filled with oil, Maximum and mini-mum oil level are indicated by marks on the dipstick.Only high-grade branded oils conforming to the following specifications should be used:
