Description of the seepex Progressive Cavity
Pump and Accessories
4.1
General Description, Design and Mode of Operation
Like all progressive cavity pumps, seepex pumps
belong to the rotating positive-displacement pump
family. The characteristic attribute of these pumps is
the special formation and arrangement of the two
conveying elements, namely the rotor and the stator.
The difference in the number of threads possessed
respectively by the rotor and stator produces a
chamber that opens and closes alternately in line
with the constant turning motion of the rotor,
effecting the continuous transportation of the
conveying product from the suction side to the
pressure side.
The geometrical formation of the two conveying
elements combined with the constant contact that
exists between them result in sealing lines that effect
an airtight seal between the suction and pressure
side in every position of the eccentric screw, even
when the pump is stationary. The pump owes its
high suction capacity to this
sealing between the suction and pressure sides.
4.2
Mechanical Design
Please consult the sectional drawing, Point 9,
for the mechanical design of the pump. The data
sheet, Point 9, gives information on the design of the
pump housing, stator, rotor and rotating components.
Refer to document OM.
SEA. __, for information on
the design of the shaft seal.
The data sheet, specifies details of the design of the
drive engine. Further details are
given in the appended manufacturer's documents,
Point 10.
4.3
Accessories
Consult the data sheet for information.
4.4
Dimensions, Weight
Consult the appended dimensional drawing,
4.5
Design Variants
Refer to the data sheet, Point 9, for the design of the
seepex progressive cavity pump. Other design
variants are possible, whereby seepex must first
check whether a particular pump is suitable for the
intended purpose.
4.6
Operating Site Specifications
Operating site specifications are listed in the data
sheet, Point 9. Details of the space required for
installation, operation and maintenance are given in
Point 5.2.1.
