Pump with integrated inverter
Description
Pump with integrated inverter
The ESPA Speedrive (ESD) variablefrequency controller can be integrated
with the following ESPA pumps: MULTIESD, PRISMA-ESD and Multi VS-ESD.
Combining the pump with the ESD
extends the hydraulic range for each
model. This guarantees the most
efficient operation at various duty points
by working beyond the restrictions of a
fixed speed pump curve.
The ESD module can be adapted to the
three-phase motors of both new ESPA
pumps and units in existing
installations.
Using ESPA ESD improves the service
quality of the system and extends the
unit’s life span.
A further advantage of ESD is that the
large accumulation vessel used in fixed
speed systems can be replaced by a far
smaller unit.
The variable-speed system delivers
constant pre
