The Rovatti electric submersible pumps 4ES are easily installed into wells and tanks, they are suitable for water supply, municipal and industrial applications.
They consist of two main elements:
– Pump body
– Submersible motor
Centrifugal multistage pumps with incorporated non return valve the in delivery bowl and suction grid mounted in the suction bowl. The wet end is suitable to be coupled with standard submersible motors.
Thermoplastic resin hydraulic components.
AISI 304 delivery bowl and suction bowl.
AISI 304 stainless steel shafts, bolts, couplings, grid, cable protections.
They are suitable to deliver a wide range of liquids including chemically aggressive water, with maximum 40g/m³ suspended solids. Maximum running time at zero delivery (closed gate valve): 2 minutes.
These pumps are typically used for residential, commercial, municipal and industrial water extraction (abstraction), water wells, irrigation systems and pressure boosting.
Single and three-phase Franklin motors are supplied as standard. Most models available from stock.
