1.02 PRINCIPLE OF OPERATION
Hy~Line and Ultima pumps have 2 rotors
which turn in opposite directions. Fluid
enters the pump from the inlet port and fills
the space between the rotors. This fluid is
carried around the outside of the rotors and
is forced out of the discharge port as the
rotor lobes mesh together see Figure 1.
Each rotor is supported on a shaft and when
the pump is running within its operating
limits, the rotors never touch the inside of
the rotor case, or each other.
1.03 OPERATING CONDITIONS
Hy~Line and Ultima pumps are designed
using modern design techniques and
manufactured from high quality materials.
However, there are certain limitations to the
operating conditions of the pump to ensure
long life and trouble-free running. During
pump selection and specification these
limitations are taken into account and must
not be exceeded.
Every pump is supplied with a Performance
Data Sheet which gives details of these
limitations. These are:-
Maximum Pressure
Maximum Temperature
Maximum Viscosity
Maximum Particle Size
Maximum Speed
Maximum Input Shaft Torque
Maximum Input Shaft Radial Load
These limitations and performance
characteristics vary from one pump size to
another, and from one pump specification to
another within the same pump size.
Take particular care over the following:-
Materials: Ensure that all
the fluids to be
pumped, including cleaning and sterilizing
agents, are compatible with the materials
from which the pump is constructed.
See section 2.10 for details of shaft or seal
types and section 2.11 for alternative seal
materials, i.e. seal faces and elastomers.
