Gear units ensure smooth operation in wastewater applications

Nord Drivesystems has developed products that comply to safety and hygiene standards and can handle harsh washdown environments.

The products are available in size ranges suitable to every industry – from food and beverage and pharmaceutical right through to wastewater and mining.

Products are locally assembled and Nord has a large local stock holding and service team trained to help customers with commissioning and service.

The company recently supplied product at a wastewater treatment at a municipality that supplies approximately 2.5 million people in a metropolitan area with process water. To enable the bacterial decomposition of dirt particles, the wastewater needed to be oxygenated by constant churning. Two large, geared motors propelled the mixers around the clock. In the outdoor facility, temperature vary throughout the year.

The facility contained drive technology that was nearly 30 years old and needed to be replaced step by step. The original suppliers had discontinued the lines, which made spare parts hard to come by. Also, the originally installed gear units required maintenance to a problematic extent. In particular, the fluctuations in temperature have frequently affected the lubrication.

Getting a grip on heat
Searching a new supplier, the municipality found Nord Drivesystems, which had been operating a sales office in the country since 2003. Two combinations of Nord helical shaft gear units and

Siemens motors were installed, and have since proven themselves during continuous operation.

Nord used a high-quality synthetic long-life lubricant for the helical shaft gear units. It withstood the ambient temperatures considerably better than mineral oil – with the latter, the oil film would break down at high temperatures, resulting in increased wear and tear.
Each gear unit required 210 l of oil, which had to be changed after approximately 20,000 hours of operation. Other manufacturers stipulated shorter maintenance intervals, which made a difference at a price of the oil. An oil cooling system additionally increased operational safety in the Nord gear units – a temperature sensor constantly monitored the temperature of the lubricant and activated the cooling system as soon as a configurable limit was exceeded. In this application, the limit is 60°C.

Heated oil was then pumped out, cooled by an oil cooler and returned to the gear unit. When the temperature fell below 40°C the cooling system switched off automatically.

Drive technology in detail
Currently, there are two helical shaft gear units with a 132kW performance from Nord’s SK 12382VZ series that are installed at the waste water treatment plant. They are used in combination with Siemens motors via IEC adapters.

Nord’s helical shaft gear units are available as two- or three-stage basic types with hollow or solid shafts, in foot-mounted, flange-mounted, or face-mounted versions – each with the same housing. Suitable for integration into limited installation spaces, they can be combined with many components from the modular Nord system.

Atex models and models with IP55 or IP66 protection are available on request for all types. All gear units are manufactured according to the UNICASE concept, originally developed by Nord in 1981. This enables maximum performance for small gear dimensions and ensures operational safety, high efficiency, high output torques, high resistance to axial and radial loads, low-noise operation, low maintenance and a long lifetime.

NORD DRIVESYSTEMS helps reduce serious safety risks with gas explosion protected motors and gear units

Flammable gases and dust in processing industries create serious safety risks for both people and machines.

But NORD DRIVESYSTEMS is supplying equipment that can keep people safe in industries spanning from the chemical, pharmaceutical and food sectors.

Its range includes ATEX compliant drive solutions such as dust or gas explosion protected motors, gear units and electronic drive technology for zones 1, 2, 21 or 22.

NORD supplies individually configured drive systems in accordance with EU Directive 2014/34/EU and IEC Ex for applications in potentially explosive atmospheres.

This leading drive specialist company offers extensive experience with gas and dust explosion protection and has for more than a decade produced explosion protected motors.

These explosive protected drive systems can be operated in category 2D or 3D dust atmospheres (Zones 21 and 22), as well as in category 2G or 3G gas atmospheres (Zones 1 and 2). A combined dust/gas explosion protection is available.

NORD supplies application-specific drive solutions with individual configurations and equipment from its SAP-supported modular system with validated configuration processes according to ISO 9001.

Where customer specifications are concerned, NORD calculates individually by testing the ATEX conformity and delivers the appropriately modified type plate. If required, the maintenance intervals, which are determined for the specific application can be stamped on the type plates.

The company offers flexible drive concepts with motors which are optionally designed for use with inverters as well as the option of IEC or NEMA motor mounting. In most cases, it can be mounted directly on the gear unit for an especially compact solution.

Depending on the explosion protection zone, various options can be integrated, such as the external fan, backstop, and brake. The explosion protection range by NORD includes systems for ambient temperatures up to 60 degrees and is characterised by delivering world-wide with documentation in more than 20 languages.

NORD will be showcasing the ATEX and other units at CeMAT from 24 – 26 July at the Melbourne Exhibition Centre.

Single stage helical gear unit

NORD Drivesystems has extended its successful NORDBLOC.1 series with a single stage gear unit for applications with high speeds and torques.

The new single stage NORDBLOC.1 helical gear unit from NORD DRIVESYSTEMS was specifically designed for applications with high speeds and torques. The gear unit is especially robust, efficient, quiet and compact.

The new NORDBLOC.1 helical gear unit features ultimate efficiency, high torsional rigidity, low running noise and a long service life. In addition, it meets even the most stringent hygiene requirements thanks to its wash-down design. These innovative gear units do not have any separating joints or closing caps, this increases the stability of the product and at the same time provides a smoother surface on which neither liquids nor solid materials can accumulate.

The FEM-optimised UNICASE housing ensures maximum strength and rigidity. In addition to increased rigidity the internally reinforced design also ensures especially quiet running. All bearings and seal seats are contained within the casing to help eliminate joints which can weaken the housing and allow for oil leakage.

Bores and mounting faces are machined in one step, enabling extremely precise tolerances — thus ensuring accurate positioning of gear teeth, bearings and seals – and an overall longer life for all components. The housing is made from high strength, corrosion resistant aluminium and is therefore especially lightweight and robust.

Martin Broglia, Managing Director of NORD DRIVESYSTEMS says that the new edition to its already comprehensive range is welcomed to ensure 100% customer satisfaction. “In addition, NORD offers added options for this unit such as nsd tupH surface treatment for more protection,”

“The smooth, easy to clean housing makes the NORDBLOC.1 gear unit particularly suitable for users operating in hygienically critical sectors such as the food or pharmaceutical industries. These gear units are generously dimensioned and can withstand large radial and axial forces,” said Broglia.

A big benefit of the large bearings is the larger diameter of the internal shafts, which increases the bearing strength. The gear wheels are made from case-hardened steel and permit high short-term overloads.

The new NORDBOLOC.1 is available in five sizes with motor powers from 0.12 to 7.5 kW for output torques of up to 280 Nm. All variants are available as flange mounted (B5 or B14) or foot/flange mounted versions. Options for IEC and NEMA motor mounting as well as a wide range of equipment variants for shafts, bearings and lubrication can be flexibly implemented.

“The NORDBLOC.1 series truly strengthens our customer offering as its robust, efficient, quiet and compact. We have created a reliable and economical drive solution for pumps, mixers and fans, as well as for conveyor technology applications,” said Broglia.
