BL-E version
Spiral housing pump with dimensions in accordance with DIN EN 733.
All pump housings are equipped with cast-on pump feet. From motor power ≥ 5.5 kW: Mo-
tors with cast or screwed-on feet.
Installation on a base is recommended for units with a rated power of ≥ 5.5 kW and above.
Depending on the differential pressure and the set control mode, the electronic module reg-
ulates the speed of the pump to a setpoint that can be adjusted within the permissible con-
trol range.
Continuous adaptation of the hydraulic output adapts to the system's changing require-
ments. Changing requirements can be expected especially when thermostatic valves or mix-
ers are used.
The basic advantages of the electronic control are:
• Energy saving at the same time as reduced operating costs
• Reduced number of differential pressure valves required
• Reduction of flow noise
• Modification of the pump to changing operating requirements

Available control modes are:
Constant differential pressure (Δp-c)
The control keeps the delivery head constant at the set differential pressure setpoint H
Control is independent of the volume flow and operates until the maximum characteristic
curve is reached.
