The NEMO® BP progressing cavity pump with feeding screw and bridge breaking paddle is the optimal pump for continuous, pressure-stable, gentle and low-pulsation conveyance, as well as dosing in proportion to rotation speed, of media that tend to bridge in nearly all branches of industry.
The NEMO® BP convinces with a broad spectrum of applications. It is preferably used for conveying compacted, crumbly, lumpy, solid-loaden, shear-sensitive, sticky to dry, thixotropic, dilatant as well as abrasive or adhesive media. The special features of this model include the patented, horizontally positioned feeding screw, the integrated bridge breaker and the enlarged rectangular hopper. Optimal feed into the conveying elements is guaranteed by means of the coupling rod with this feeding screw and the removable conical force-feed chamber. The bridge breaker prevents bridging and makes the mixing of aggregates possible. The hopper dimensions can be adjusted to the individual application case. The block construction of the NEMO® BP with flanged drive is particularly compact and economical.
In wear- and corrosion-resistant designs including the wear-free ceramic rotor NEMO CERATEC®.
Vulcanized into the tube with sealing on both sides in a variety of elastomers, plastics and metals. Stator inlet with hopper-shaped opening for improved feed of the product into the conveying chamber.
3 Drive Chain
Drive and connecting shaft with a coupling rod with patented, horizontally positioned feeding screw for optimal 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 has integrated bridge breaker for the prevention of bridge building and for the mixing of aggregates (e.g. for conditioning of drained sludge), enlarged rectangular hopper and conical force-feed chamber as well as coupling rod with patented, horizontally positioned feeding screw for optimal feed to the conveying elements. Flange and threaded connections in accordance with DIN and international standards. Materials in 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.
