Used Progressing Cavity Pump / P-1204
This used progressing cavity pump can convey a large quantity of media gently and with low pulsation. The used progressing cavity pump, also called eccentric screw pump, with the type designation NM076SY02S08K, was manufactured by the German company Netzsch in 1999 in mild steel.
This used progressing cavity pump is driven by a 13.5 to 17.5 kW motor and the maximum operating pressure is 6 -8 bar. The pumping capacity is about 15 -35 m3/h. Nominal speed of the gear output shaft is 178 - 344 rpm.
Dimensions: L 2900 x W 450 x H 500 mm This used eccentric screw pump, was used for feeding a chamber filter press in a sewage treatment plant.

Technical data of the Used Progressing Cavity Pump
Progressing cavity pump
Progressing cavity pumps are used in all branches of industry for the continuous conveyance of almost all media. In particular, they are used for viscous, highly viscous media such as slurries, slurry, petroleum and greases.
Functional principle of a progressing cavity pump
All progressive cavity pumps belong to the group of rotary positive displacement pumps. The characteristic feature of these pumps is the special design and arrangement of the two conveying elements , the rotor and the stator. The different number of threads of the rotor and stator creates a chamber which opens and closes alternately in an uninterrupted sequence as the rotor rotates, transporting the material continuously from the suction side to the discharge side.
Due to the geometric design and the constant contact between the two conveying elements, sealing lines are created which ensure absolute closure between the suction and pressure sides in every position of the eccentric screw, even when the machine is at a standstill.This seal between the suction and discharge sides gives the pump its high suction capacity. However, it should be noted that wear is very high with abrasive media. This can lead to high operating costs.
