About Booster 2GPE with E-SPD
Pressure boosters with two three-phase horizontal or vertical pumps, with hydraulics in AISI 304 or AISI 316 and special mechanical seals on request, with integrated E-SPD inverter. Used for water supply for distribution networks in the building services and general industry sectors and domestic pressurisation
Features
- Versatility
- Compact dimensions
description Booster 2GPE with E-SPD
Centrifugal pump fitted with an open radial flow impeller in AISI 304 stainless steel, also making it suitable for pumping liquids that are not completely clean, but with solid parts up to 19 mm in diameter.
The DWO electric pump’s pressed AISI 304 pump body is obtained through the hydroforming process, providing sturdy construction, hydraulic efficiency and reliability.

SPECIFICHE DELLE CURVE 2GP(E)
Le specifiche riportate di seguito si riferiscono alle curve illustrate nelle pagine successive.
Tolleranze in conformità con ISO 9906 Allegato A
Le curve si riferiscono a una velocità effettiva dei motori asincroni a 50 Hz
Le misurazioni sono state effettuate con temperatura dell’acqua pulita di 20°C e con viscosità cinematica
n = 1 mm2/s (1 cSt)
La curva NPSH è una curva media ottenuta nelle stesse condizioni delle curve di prestazione.
Le curve continue indicano l’intervallo di funzionamento consigliato. La curva tratteggiata è solo indicativa.
Al fine di evitare il rischio di surriscaldamento, le pompe non devono essere utilizzate a una portata inferiore al
10% della portata di efficienza massima.
Spiegazione dei simboli:
Q = portata
H = prevalenza totale
P2 = ingresso alimentazione pompa (potenza albero)
h = efficienza della pompa
NPSH = prevalenza netta di aspirazione positiva richiesta dalla pompa
