Eccentric screw pump used / P-1219
The eccentric screw pump used, with the type designation NM038BY04S24B, was manufactured by the company Van Wijk & Boerma in mild steel.
This used eccentric screw pump is driven by an 3 kW motor and the maximum delivery pressure is 24 bar. This eccentric screw pump or sludge pump, was used in cooperation with a chamber filter press in a wastewater treatment plant for sludge dewatering.
This pump works with an operating voltage of 230 / 400 V, a frequency range of 50 Hz, a protection class of 55 and DN 80 flanges. In the meantime the pump has been dismantled and can be inspected in our machine warehouse. Please contact us for an appointment.
The dimensions of the eccentric screw pump used, are as follows:
Length 2100 mm width 300 mm height 300 mm and the weight is about 120 kg

Technical data of the eccentric screw pump used
Eccentric screw pump used
Eccentric screw pump used are used in all industries for continuous promotion of virtually all media. Specifically designed for viscous media as slurries, liquid manure, oil and fats, the eccentric screw pump finds its use.
Functional principle of a eccentric screw pump used
All eccentric screw pumps belong to the group of rotary displacement pumps. The characteristic feature of these pumps is the special design and arrangement of the two conveying elements, the rotor and the stator.
As a result of the different number of rotations of the rotor and the stator, a chamber is formed which opens and closes in a continuous sequence during the rotational movement of the rotor, the material to be conveyed being continuously transported from the suction side to the pressure side.
Due to the result of the geometrical design and the constant contact between the two conveying elements, sealing lines are produced, which provide an absolute seal between the suction side and the pressure side in any position of the eccentric screw, even at a standstill. Due to this closure between the suction side and the pressure side, the pump receives its high absorbency. However, it should be noted that on abrasive media, the wear is very high. This can lead to high operating costs.
