3.7.3Influences

The real sound level of the pump unit can for several reasons deviate from the values listed in the tables above.

•Noise production decreases when pumping high viscosity liquids due to better lubricating and damping properties. Moreover the resistance torque of the idler is increasing due to higher liquid friction which results in lower vibration amplitude.

•Noise production increases when pumping low viscosity liquids combined with low working pressure because the idler can move freely (lower charge, lower liquid friction) and the liquid does not dampen much.

•Vibrations in piping, vibrating of the baseplate etc. will make the installation produce more noise.

3.8Maximum and minimum allowable temperature

The maximum allowable temperature of the pumped medium is 260°C but the temperature limits must be considered depending on the material used for the idler bearing bush, O-ring material and material of the permanent magnets used in the magnetic coupling. The minimum allowable tempera- ture is -20° for cast iron and -40°C for stainless steel casing parts.

3.9Jacket options

S-jacketsare designed for use with saturated steam or with non-dangerous media. They are provided with cylindrical threaded connections according to ISO 228-I.

Maximum temperature:

200°C

Maximum pressure:

10 bar

T-jacketsare designed for use with thermal oil and apply to the DIN4754 safety standard for thermal oil transfer. This DIN standard specifies flange connections for temperature from 50°C upwards and jackets of ductile material for temperature from 200°C upwards. Both are provided in the T-design.

T-jackets could also be used for over heated steam or more dangerous media.

The flanges have a special shape with welding neck based on PN16 dimensions.

Maximum temperature:

260°C

Maximum pressure at 260°C: 12 bar
