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.).

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, economicaland silent.

Hydraulic assembly in stainless steel:anti-corrosive safety and increasedpump service life.

Motor rolling bearing fitted in thefront endshield, amply dimensionedand leaktight.

Suction rings between very thick cells-insensitive to thermal expansion,elimination of risks of seizing up.

Maximum reliability - high efficiencydue to impeller profile limiting thenumber of stages, shaft size and axialthrust.

Standardized mechanical seals, +110C maximum, maintenance free.

Easy installation.
