* Hermetically Sealed Type:
A Hermetically Sealed Type motor utilizes windings of standard construction and insulation thickness. The windings are encased and Hermetically Sealed within the external shell casing on the outside and an internal tube or liner inside the bore. The Hermetically Sealed enclosure eliminates the possibility of water leakage into the winding. The liquid medium circulates between the rotor and stator liner providing lubrication and cooling to the bearings.
* Wet Winding Type :
A Wet Winding Type motor is one in which the motor windings are in direct contact with a liquid medium. The medium is clean, clear water. A pressure balancing system prevents exchange of the motor liquid medium and well water due to thermal expansion and contraction when the motor is operating. The liquid medium fills the inside of the motor and surrounds both the stator windings and the rotor. A completely waterproof insulation is used on the magnet wire used for the stator windings. The liquid medium inside the motor air gap and coils acts as a heat transfer device by circulating through the windings and transferring heat to the external casing. Dissipation of this heat occurs as the well water flows at a required velocity over the external case. As is the case in all submersible type motors, the internal liquid medium is also used for bearing lubrication.

CPXV ISO Overhung, Vertical Sump Pump
Heavy-Duty Casing with multi-ribbed discharge flange conforms to ISO 5199 design criteria.
High Efficiency, Open Impeller with backvanes and shroud provides axial balance to reduce maintenance and downtime cost by extending mechanical seal and bearing reliability. Low NPSHR design decreases operating cost and extends life.
Standard Column Length of 500 mm translates to a minimum sump depth of 0.7 m. Subsequent column lengths are available in 100 mm increments, up to the longest standard sump pump depth of 10 m.
Heavy-Duty Thrust Bearings with axial adjustment made at soleplate level.
Radial Bearings are available in a number of material options, including silicon carbide, offering compatability across a spectrum of liquids. The bearings can be flushed by product or from an external source.
CE Marked and compliant with applicable European directives, such as ATEX.

MULTi-V
CARACTÉRISTICS
In-Line series 50 Hz
OPERATING LIMITS
Flow rates up to : 140 m3/h
Head up to : 240 m
APPLICATIONS
Pumping of non-loaded clear liquids for the housing.agricultural and industrial sectors :
- Water supply - Boosting
- Sprinkling - Irrigation
- High-pressure washing
- Fire protection
- Heating - Air conditioning
- Water treatment (demineralization.filtering)
And incorporation in all modular systems.
Fluids pumped
• 304 range: clear non-aggressive liquid (drinking water, water with glycol)
• 316L range: aggressive liquids (sea water. demineralized water, chlorinated water, etc.).
ADVANTAGES
• Stainless steel hydraulic unit : anticorrosion safety and increased pump lifetime.
• Oversized (lantern) bearing for longer motor bearing life; eliminates axial and other adjustments of moving parts.
• Tungsten carbide intermediate bearing to control and eliminate vibration and stabilize the rotor with a large number of stages.
• Thick impeller sealing rings between stages for insensitivity to thermal expansion
and elimination of risk of seizing up.
• Optimal reliability: high-efficiency impeller profiles limit the number of stages, the sizes of the shafts, and axial thrusts.
• Standardized mechanical seal, can be used up to +120°C without maintenance.
• Easy to install: In-Line ports.
MULTi-V 36C, 60C, 80, 100
• Easy maintenance : Mechanical Cartridge Seal available on all models. Allows the
fitter or the operator to replace the MS without removing the pump
• Concept Spacer available on all models ≥11 kW. Allows the fitter or the operator
to replace the MS without removing the pump or the motor.
