This range is compact and characterized by including one or more EFAFLU vertical multistage pumps (without any maximum limit) made from AISI 304, installed on a baseform and discharge manifold in AISI 304 stainless steel with a gate valve and check valve in each of the pumps as well as a general gate valve on the manifold. The system includes, in the control panel, a Premium Controller as well as all the automatisms, frequency converters and protections required for independent operation with the system operating at variable velocity between 25 and 51 Hz. The pumps include a replaceable membrane tank for potable water. The energy consumption and guarantee of constant pressure maintenance or constant flow rate are optimised according to the versions adopted for the operation management of the actual station:
CFD – Each pump in this version has a Dedicated Frequency
CFU – This version has one Single Frequency Converter
with alternation between all the pumps. The remaining
pumps operate at constant velocity.
DCF – This version is characterized by having Two Frequency
Converters dedicated to the auxiliary pumps with
half the capacity of the main pumps.
The main pumps operate at a constant velocity.
