The NEMO® BY block pump in industrial design can be used in environmental technology, the food and chemical industries, but also in the oil & gas upstream as well as the mid-/downstream sector for a wide variety of pressure-stable conveying or dosing tasks.
From low-viscosity media to hardly flowing products, with or without solid content, shear-sensitive, sticky or abrasive, with the NEMO® BY progressing cavity pump even difficult substances can be conveyed gently and with low pulsation, regardless of fluctuations in pressure and viscosity. In addition, the progressing cavity pump guarantees flow rates proportional to speed with high dosing accuracy over the entire speed range. In block design with flanged drive, this NEMO® pump is especially compact and economical. Moreover, the NEMO® BY is distinguished by its low investment, operating and maintenance costs. Four rotor/stator geometries are available for the various products and applications.
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.
2.2. Stator with iFD technology
The iFD-Stator® 2.0 consists of a two-part reusable housing with a polygonal profile and the NEMOLAST® elastomer housed within. The advantages of this new technology include a lower breakaway torque, higher efficiency, increased service life, simple and quick replacement, and environmentally friendly.
3 Drive chain
Coupling rod 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
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.
