Solutions provider for difficult pumping applications Netzsch Pumps North America has introduced the iFD-Stator 2.0, which it says combines efficiency, economy and environmental safety in one system.

Featuring a two-part, reusable stator housing and replaceable stator, the iFD-Stator 2.0 is compatible with all the Netzsch Nemo NM series of progressing cavity pumps. Such pumps have a broad application range and are used in all branches of industry for the continuous, pressure-stable, gentle and low-pulsation conveyance of almost any substance. The company says its positive-displacement pumps, which include its Nemo series, have been used for decades reliably in the demanding mining industry.

The company, with its South African base in Johannesburg, notes that changing the stator within the housing is remarkably easy, with simple, compression-free assembly and disassembly; the defined compression for the iFD-Stator 2.0 is automatically generated when the elastomer collar is fastened. Moreover, the new housing concept of the iFD-Stator 2.0 is easier to handle than the previous generation and delivers a longer service life than competing options, leading to reduced downtime and maintenance.

The iFD-Stator 2.0 delivers reduced pulsation and improved fluid flow, compared with a conventional stator design, as well as a considerable increase in efficiency, owing to reduced starting and running torque. There is no limitation of speed or pressure when measured against the standard stator and the axial mobility of the elastomer leads to a prolonged service life.

Replacement of the stator costs less than the traditional stator design and is more environment friendly because the housing can be reused, notes Netzsch, adding that, overall, the iFD-Stator 2.0 delivers reduced life-cycle and energy costs over other stator designs.

Nemo progressing cavity pumps are known for their continuous, pressure-stable, gentle and low-pulsation conveyance of almost any process fluid without being affected by fluctuations in pressure and viscosity, says Netzsch.

The diverse substances handled in mining include wastewater, mineral slurries, thickened sludge, kaolin suspensions, filtrates, zinc sludge and drilling muds, which Nemo pumps are well suited to transport, explains the company. “These abrasive and viscous substances are handled with ease.”

The pump is available in 11 styles with four rotor/stator geometries and a selection of engineered joints that can be tailored to suit specific applications. Conveyance volumes can be configured in proportion to rotation speed, with high dosing precision over the entire rotational-speed range.

Netzsch Pumps & Systems has served markets worldwide for more than 60 years, providing solutions for applications in every industry type. Besides Nemo progressing cavity pumps, Netzsch supplies Tornado rotary lobe pumps and Notos multiscrew pumps, as well as grinding machines, barrel emptying units, dosing technology and accessories. With a workforce of more than 2 000, Netzsch Pumps & Systems is the largest business unit in the Netzsch group.
