Getting the right mix
New combination tackles mixing and agitation processes
The MAXXDRIVE industrial gear units from NORD DRIVESYSTEMS with the new SAFOMI-IEC adapter is specifically developed for mixers to improve operational reliability and reduce the need for the replacement of wearing parts.
In combination with the NORDAC FLEX SK 200E frequency inverter for the power range up to 22 kW, a flexible unit with low maintenance is offered, states the company.
High output torques
MAXXDRIVE industrial gear units, an integral part of the NORD portfolio for 10 years, “offer high output torques from 15 to 282 kNm and ensure smooth operation even under demanding conditions,” says NORD. The FEM-optimised and compact design enables operation under ultimate external loads.
For agitation applications, a combination with the SAFOMI-IEC adaptor (SAFOMI = Sealless Adapter For Mixers) is recommended, in which an oil expansion chamber is directly integrated.
SAFOMI is available for MAXXDRIVE parallel gear units in the sizes 7 to 11 covers maximum output torques from 25 to 75 kNm. SAFOMI impresses with its compact and simple design and integrated oil equalisation volume, which means that there is no need for oil tanks and hoses or the shaft sealing ring between the gear unit and the IEC cylinder, which is prone to leakage and wear.
Operational reliability stepped up
Using the SAFOMI-IEC adapter, instead of the standard IEC adapter, on the agitator drive is reported to increase operational reliability and lower maintenance costs. “Not only is the oil level and thus the required oil volume lower, but, thanks to fewer attached components, the installation space is also reduced.”
For the further reduction of wearing parts and attached components, NORD recommends a combination of MAXXDRIVE industrial gear unit, SAFOMI-IEC adapter, a drive motor and NORDAC FLEX SK 200E. “The frequency inverter can be flexibly installed and features a high output range, as well as a wide choice of optional functions and accessories. The SK 200E can be directly mounted on the motor without control cabinet.”
