The VL2 is a range of stainless steel vertical multi-impeller
pumps, carefully engineered to give you the best in performance,
reliability, durability and ease of maintenance.
PUMP INSTALLATION AND APPLICATIONS
These pumps are suitable for pumping clean water and fluids
which are not chemically aggressive to the pump components. Their
high performance and dependability make them suitable for use in
domestic and civil sectors, particularly in installations with insufficient
ventilation, in tight spaces and subject to jets of water, etc.
They can be submerged.
STRUCTURAL CHARACTERISTICS
- AISI 304 Stainless steel EXTERNAL CASING with 1¼
inch gas thread delivery opening UNI ISO 228/1
- Noryl GFN2V technopolymer IMPELLERS
- Noryl GFN2V technopolymer DIFFUSERS
- DIAPHRAGM in stainless steel AISI 304 complete
with wear rings.
- EN 10088-3 - 1.4104 stainless steel MOTOR SHAFT
- MOTOR BRACKETS in stainless steel AISI 304.
- DOUBLE SEAL SYSTEM silicon carbide/silicon carbide mechanical
seal on the pump side, and lip seal on the motor side (with barrier
oil chamber to lubricate and cool the sealing surfaces in the
absence of water).
- AISI 304 stainless steel BOLTS
- Removable and re-windable enclosed induction MOTOR, suitable
for continuous duty. A thermal cutout device (motor protector)
is incorporated in single phase motors. Motor cooling is assured
by the liquid in which the pump is immersed.
- INSULATION class F (provides the motor with a considerable
overload tolerance and substantially increases the service life
of the motor itself).
- PROTECTION IP 68.

with removable connector.
- CONSTRUCTION AND SAFETY STANDARDS in compliance with
EN 60 335-1 (IEC 335-1, CEI 61-150) EN 60034-1 (IEC 34-1, CEI
2-3).
- CONTROL BOX with capacitor and schuko plug in single
phase motors.Optional extra for three phase motors.
