Variable-speed, multi-stage, centrifugal electric pump in a vertical mono-block unit, coupled with a normalized standard engine, controlled by the ESPA ESD frequency inverter.

Sturdy and compact, designed for pressurising homes, irrigation systems and clean-water pumping applications that require a high efficiency pump.

Designed to work in parallel on multiple devices, it is an optimized solution for booster sets, especially recommended for potable water applications. Also suitable for transferring moderately aggressive liquids, de-mineralized water, water and glycol, etc.

Their construction is noted for allowing easy maintenance of the mechanical seal, which can be handled in the whole range without needing to remove the motor. Pump casing available in different configurations and connection types, for easy installation, handling and maintenance. Completely manufactured in AISI304 stainless steel, allowing work in a temperature range between -20 ºC and +120 ºC.

The pressure reading is taken in real time to adapt the engine's revolutions and adjust the flow provided to the facility's demand. This achieves greater comfort for the user, by ensuring a constant water supply pressure. The reduction of the engine frequency also implies a significant energy saving and better efficiency of the facility.

They are particularly recommended for pressurisation at constant pressure.
