STAINLESS STEEL MULTI-STAGEHORIZONTAL PUMPS

2 pole - 50 Hz2 ranges: stainless steel 304 and 316L

Pumping of clear non-loaded fluids in thehousing. 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.).

STANDARD CONSTRUCTION

ADVANTAGES

DESIGN

HYDRAULIC PRESELECTION CHARTS

• Hydraulic part

ALL STAINLESS STEELHorizontal, centrifugal, not self-priming.Multi-stage from 2 to 6 stages.Axial suction, vertical discharge upwards.Impellers mounted directly on the motorshaft extension.Shaft leaktightness by standardized mechanical seal.Hydraulic assembly mounted at 8 pointson a lantern bracket.

• Motor

Standard ventilated.Extended shaft end.Single-phase motor with integrated thermalprotection, automatic reset.Capacitor incorporated in the terminal box.Guiding rolling bearings of the impeller shaftlubricated for life.

Speed of rotation : 2900 rpmWindings three-phase : 230-400 VSingle-phase : 230 VFrequency : 50 Hz

(option 60 Hz)Insulating class : FProtection 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.
