Product Description
Slow-running ATP/BTP submersible agitators with step-down gear unit
Lots of thrust with little energy
Slow-running submersible agitators of the ATP/BTP type permit gentle circulation of large quantities of liquid. With large diameters and low speeds, these agitators and mixers generate maximum thrust with the smallest possible use of energy or electricity. By combining different motors, gear units and propeller types/sizes, it is possible to offer submersible motor agitators with the appropriate performance for a wide range of applications: flow generation, circulation, suspension of solids such as in water treatment, process technology, etc.
Harshest ambient conditions
For use in potentially explosive atmospheres, the submersible motor agitators in the ATP/BTP series are available in the “pressure-tight encapsulation” explosion protection category II 2G Ex d ib IIB T3 according to ATEX. The maximum coolant/medium temperature is 60 °C.
Lowest self-generated power consumption
The use of propellers with optimum hydraulic design, different gear unit ratios and high-efficiency motors (IE2 and IE3 according to IEC 60034-30) achieves maximum overall efficiency.
Mechanical seal system
It has been shown in practice that reliability and durability of shaft seals are decisive criteria for trouble-free operation. The unique seal system from streisal offers a range of advantages:
- Two highly wear-resistant silicon carbide mechanical seals (tandem version)
- Mechanical seals are protected by being mounted in a stainless steel holder
- Spring elements on the inside, not in contact with the medium
Optimally effective performance
With large propeller diameters and low speeds, these submersible agitators develop maximum thrust. The flexible positioning and alignment means that the flow direction can be adapted to the particular tank shape. The self-cleaning propeller shape ensures a constantly high agitating effect and operation without vibration, even when the medium contains fibres.
