Product details

The catalog states a liquid-temperature range of −15 to +120°C, subject to the selected configuration and liquid. The motor is described with an aluminum housing, IP55 protection and Class F insulation. These motor designations do not establish suitability for an explosive atmosphere or every coolant mixture.

The construction description identifies an electrophoretically coated cast-iron outlet and a stainless investment-cast inlet base with filtering openings. Internal parts are CNC machined. The inlet arrangement and immersion length should be reviewed against the tank’s minimum level, available depth and chip or solids management.

The manufacturer supplies separate QDYB2 and QDYB4 performance curves and dimensions. The range endpoints belong to different selections and must not be combined into one duty. Confirm the exact curve, immersion depth, connection layout and materials for the coolant, lubricating liquid or wash fluid used by the machine.

SELECTION NOTES

Specify the operating duty

Provide required flow and head, coolant composition and temperature, tank depth and minimum level, solids conditions and supply voltage. Confirm the QDYB2 or QDYB4 curve, immersion length and installation dimensions.

Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
