The ideal pump for crumbly media in a compact design.

NEMO, BO, Funnel-Shaped, Progressing Cavity, Pump, Netzsch

The NEMO® BO Progressing Cavity Pump with square/rectangular hopper and coupling rod with feeding screw and force-feed chamber is employed in almost all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance. This special design guarantees better feed into the conveying elements. Another great advantage of the NEMO® Progressing Cavity Pump is its ability to dose nearly any substance in proportion to rotation speed. In block construction with a flanged drive, this pump is particularly compact and economical.

Features of the NEMO® BO Funnel-Shaped Progressing Cavity Pump

  • funnel housing with rectangular inlet flange and feeding screw with force-feed chamber to provide optimal feed for your slowly flowing and pasty media into the conveying elements

  • continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity

  • conveyance volume in proportion to rotation speed with high dosing precision over a broad rotational-speed range

  • high pressure capability without valves

  • stator with funnel-shaped entrance for optimal filling of the conveying chamber

The NEMO® BO Funnel-Shaped Progressing Cavity Pump offers you:

  • gentle product conveyance

  • pump connections in accordance with national and international standards, as well as in specially designed models

  • easy serviceability

1. Rotor
In wear- and corrosion-resistant designs including the wear-free ceramic rotor NEMO CERATEC.

2. Stator
Vulcanized into the tube with sealing on both sides in a variety of elastomers, plastics and metals. Stator inlet with funnel-shaped opening for improved feed of the product into the conveying chamber.

3. Drive Chain
Coupling rod with feeding screw and force-feed chamber for improved feed into the conveying elements and two gimbal joints for the transmission of power from the drive to the rotor.

4. Shaft Seals
Standard with single-acting, bi-directional, wear-resistant mechanical seal. Upon request, with single- or double-acting mechanical seals of varied designs and from various manufacturers, cartridge and special seals as well as packed glands.

5. Suction and Discharge Housing
Pump housing with square/rectangular hopper. The funnel dimensions can be adapted to the individual application.
Flange and threaded connections in accordance with DIN and international standards. Materials in cast iron, steel, chrome-nickel-steel rubberized; also special materials upon request.

6. Block Construction
The drive is flanged directly to the lantern of the pump, resulting in compact dimensions, low total weight, constant axial heights irrespective of the construction type and size of the drive, and ease of maintenance and serviceability as well as high efficiency.
