Peripheral Immersion Pump
Construction
Vertical close-coupled peripheral (regenerative) pumps with
submerged turbine impeller, seal-less, reversible.
Port dimension to EN 12157.
Submerged deph 170 mm.
Applications
For clean liquids without abrasives, without suspended
solids, non-explosive, non-aggressive for the pump materials.
For the reduced dimensions, these pumps are very well
suited for use with temperature controllers, chillers, and
air-conditioning machines and systems.

- with water up to 90 °C.
- oil up to 150 °C.
Max. kinematic viscosity: 20 mm2/s at 50 °C (2,9 °E).
Ambient temperature: up to 40 °C.
Max. depression 0,9 bar.
Continuous duty.
Motor
2-pole induction motor, 60 Hz (n ≈ 3450 rpm).
B-VT: three-phase 220/380 V.
Insulation class F.
Protection IP 54.
Constructed in accordance with: IEC 60034.
