The direct-driven SPR agitator is Geppert Rührtechnik’s solution for industrial mixing applications that require turbulent mixing at high peripheral speeds. The SPR is driven by a three-phase motor with poles between 2 and 8 and drive ratings ranging from 0.25 kW to 75.0 kW. Upon request, the SPR can also be equipped with a frequency inverter for drive ratings of up to 7.5 kW.
The agitator shaft is directly connected to the shaft journal of the drive via a sleeve or flange coupling. For lower drive ratings of up to 3.0 kW, quick-change or precision-change couplings are also available. The standard agitator element is a propeller. Other mixing elements can be supplied depending on the specific mixing task.
- The SPR can be installed as a stationary industrial agitator. With a weight of up to 25 kg, it can also be mounted directly onto an open tank using a vessel clamp.
- Up to motor size 112, all SPR series agitators can also be supplied with a reinforced shaft.
- Type test certificate numbers for zone 0 (category 1).
