NEMO® SY progressing cavity pumps are used in demanding applications for continuous, pressure-stable, gentle and low-pulsation conveyance as well as dosing in proportion to speed in nearly every branch of industry worldwide. The progressing cavity pump convinces through an extremely broad spectrum of applications.
Preferably, thin to viscous, solids-containing, shear-sensitive, lubricating and non-lubricating, thixotropic and dilatant as well as abrasive or adhesive media are conveyed. The pump is ideally suited for high-pressure applications. Four different rotor/stator geometries are available, enabling the pump to be customized perfectly to your application case. Furthermore in bearing block design and with a free shaft end, the pump can be driven by all types of drives, such as servo motors, diesel engines or hydraulic drives.
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. The stator is oil, acid and alkali resistant.
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 Bearing block with free shaft extension
Large double bearing ensures a high level of shaft stability and thereby ideal conditions for a great variety of mechanical seals. The free shaft extension makes it possible to use any drive type including diesel and hydraulic drives.
