STAINLESS STEEL MULTI-STAGE
HORIZONTAL PUMPS
2 pole - 50 Hz
2 ranges: stainless steel 304 and 316L
Pumping of clear non-loaded fluids in the
housing. agricultural and industrial sectors:
• Conveyance - Overpressure
• Sprinkling - Irrigation
• Washing station
• Draining - Filling (ponds, pools, etc.)
• Heating - Air conditioning
• Water treatment (demineralization,
filtering, etc.).
And incorporation in all modular systems.
Catchment from a well, spring, river,
pond, etc.
Pumped fluids:
• 304 range: clear non-aggressive liquids
(drinking water, glycol water, etc.).
• 316L range: aggressive liquids (sea water,
demineralized water, chlorinated water,
etc.).

ADVANTAGES
DESIGN
HYDRAULIC PRESELECTION CHARTS
• Hydraulic part
ALL STAINLESS STEEL
Horizontal, centrifugal, not self-priming.
Multi-stage from 2 to 6 stages.
Axial suction, vertical discharge upwards.
Impellers mounted directly on the motor
shaft extension.
Shaft leaktightness by standardized
mechanical seal.
Hydraulic assembly mounted at 8 points
on a lantern bracket.
• Motor
Standard ventilated.
Extended shaft end.
Single-phase motor with integrated thermal
protection, automatic reset.
Capacitor incorporated in the terminal box.
Guiding rolling bearings of the impeller shaft
lubricated for life.
Speed of rotation : 2900 rpm
Windings three-phase : 230-400 V
Single-phase : 230 V
Frequency : 50 Hz
(option 60 Hz)
Insulating class : F
Protection index : IP 54
• Monobloc pump, compact, economical
and silent.
• Hydraulic assembly in stainless steel:
anti-corrosive safety and increased
pump service life.
• Motor rolling bearing fitted in the
front endshield, amply dimensioned
and leaktight.
• Suction rings between very thick cells-
insensitive to thermal expansion,
elimination of risks of seizing up.
• Maximum reliability - high efficiency
due to impeller profile limiting the
number of stages, shaft size and axial
thrust.
• Standardized mechanical seals,
+110°C maximum, maintenance free.
• Easy installation.
