Product details
The hydraulic section extends into the tank while the motor remains above the mounting level. The catalog describes immersion-depth adjustment using empty chambers, extension tubes or spacers. Tank depth, minimum operating level and mounting geometry therefore form part of the selection rather than being determined by motor size.
Published motors range from 0.37 to 55 kW, with IP55 protection and Class F insulation. The catalog liquid temperature range is −15 to 120°C, subject to the selected materials and seal. QDYN is a separate corrosive-liquid variant; its compatibility should not be attributed automatically to a QDYA order.
SELECTION NOTES
Specify the operating duty
Provide the working flow and head, coolant type, filtration, temperature, tank depth and minimum liquid level. Confirm immersion construction, seal compatibility, mounting flange and motor supply.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
