windsor pump co. 07/2014
TRANSCRIPT
ConstructionClose-coupled, centrifugal pumps; electric motor withextended shaft directly connected to the pump.NM: single-impellerNMD: with two back-to-back impellers (with axial thrust
balancing).Connections: threaded ports ISO 228/1 (BS 2779).The pumps in bronze are supplied fully painted.
Applications- For clean liquids without abrasives, which are, non-aggressive
for the pump materials ( solids content up to 0.2%).- For water supply.- For heating, air-conditioning, cooling and circulation plants.- For civil and industrial applications.- For fire fighting applications. - For irrigation.
Operating conditionsLiquid temperature from -10 °C to +90 °C.Ambient temperature up to 40 °C.Total suction lift up to 7 m.Maximum permissible working pressure up to 10 bar(16 bar for pumps NMD 25/190; NMD 32/210; NMD 40/180).Continuous duty.
Motor2-pole induction motor, 60 Hz (n ≈ 3450 rpm).NM, NMD: three-phase 220/380 V, 380/660 V.NMM, NMDM: single-phase 220 V.
With thermal protector up to 1.1 kW.Insulation class F.Protection IP 54.Classification scheme IE2 for three-phase motors from 0,75 kW.Constructed in accordance with EN 60034-1; EN 60034-30.
EN 60335-1, EN 60335-2-41.
Special features on request- Other voltages. - Protection IP 55.- Special mechanical seal- Higher or lower liquid or ambient temperatures.- Motor suitable operation with frequency converter.

Compact DesignThe compact design allows for easy installtion even in confined spaces.
RobustnessThe mechanical structure of the hydraulic parts in contact with the pumped liquidare dimensioned to guarantee the maximum resistence to mechanical stress.
A unique designThe lantern bracket design prevents contact with the pumps rotating parts, provi-ding protection to the end user whilst allowing for inspection of the mechanical seal.
ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providinghigh reliability under all operating conditions.

Sales and Engineering
ConstructionClose-coupled centrifugal pumps; electric motor with extendedshaft directly connected to the pump up to 30 kW, new bracketconstruction for standard motors (stub-shaft construction) from37 to 75 kW with integrated thrust bearing.Pump casing with axial suction and radial delivery on top, maindimensions and performance according to EN 733.NM(S): version with pump casing and lanter bracket in cast iron.B-NM(S): version with pump casing and lanter bracket/casing
cover in bronze. (the pumps are supplied fully painted).Connections: Flanges according to PN 10, EN 1092-2.Counter-flanges (on request)Sizes Flangesfrom NM 32/.. to NM 50/... Screwed flanges EN 1092-1, PN 16from NM 65/.. to NMS 100/250 Flanges for welding EN 1092-1, PN 10
Applications- For clean liquids without abrasives, which are non-aggressive

Cutting edge hydraulicsThe geometry of the impeller and the pump casing areoptimized to achieve maximum efficiency and the bestsuction capability.
FlexibilityThe option to choose between cast iron and bronzematerias for the hydraulic parts in contact with the pum-ped liquid allows NM and NM4 series pumps to be selec-ted for use with different types of liquids.
Compact DesignThe compact design allows for easy installtion even inconfined spaces.
Exclusive designAn innovative, patented guard prevents contact with rota-ting parts, proving protection to the end user whilstallowing for inspection of the mechanical seal.
ReliabilityThe bearing and shaft are designed to ensure the reduc-tion of the stress, providing high reliability under all ope-rating conditions.

FlexibilityThe option to choose between cast iron and bronzematerias for the hydraulic parts in contact with the pum-ped liquid allows NMS and NMS4 series pumps to beselected for use with different types of liquids.
New lantern bracket constructionThe lantern brackets incorporate a thrust bearing on thehydraulic side which guarantees the elimination of addi-tional loads on the motor bearings. The flange is sized tobe used with standard motors B35.
Exclusive designAn innovative, patented guard prevents contact with rota-ting parts, proving protection to the end user whilstallowing for inspection of the mechanical seal.
Simplified motor maintenanceThe presence of the thrust bearing on the hydraulic sidemakes it easier to remove the motor, facilitating mainte-nance operations and eliminating the risks of damage tothe hydraulic parts.
ConstructionClose-coupled centrifugal pumps; electric motor with extended shaftdirectly connected to the pump up to 15 kW, new bracket construc-tion for standard motors (Stub-shaft construction) from 18,5 to 75kW with integrated thrust bearing. Pump casing with axial suctionand radial delivery on top, main dimensions and performance accor-ding to EN 733 with additional sizes for completion.NM(S)4: version with pump casing and lanter bracket in cast iron.B-NM(S)4: version with pump casing and lanter bracket/casing

Features
Close Coupled Centrifugal Pumpswith flanged connectionsNM4, NMS4NM4, NMS4 60 Hz60 Hz
NM4
Cutting edge hydraulicsThe geometry of the impeller and the pump casing are optimized to achieve maximum efficiencyand the best suction capability.
FlexibilityThe option to choose between cast iron and bronze materias for the hydraulic parts in contactwith the pumped liquid allows NM and NM4 series pumps to be selected for use with differenttypes of liquids.
Compact DesignThe compact design allows for easy installtion even in confined spaces.
Exclusive designAn innovative, patented guard prevents contact with rotating parts, proving protection to the enduser whilst allowing for inspection of the mechanical seal.
ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providing high reliabi-lity under all operating conditions.

FlexibilityThe option to choose between cast iron and bronze materias for the hydraulic parts in contact withthe pumped liquid allows NMS and NMS4 series pumps to be selected for use with different types ofliquids.
New lantern bracket constructionThe lantern brackets incorporate a thrust bearing on the hydraulic side which guarantees the elimina-tion of additional loads on the motor bearings. The flange is sized to be used with standard motorsB35.
Exclusive designAn innovative, patented guard prevents contact with rotating parts, proving protection to the end userwhilst allowing for inspection of the mechanical seal.
Simplified motor maintenanceThe presence of the thrust bearing on the hydraulic side makes it easier to remove the motor, facilita-ting maintenance operations and eliminating the risks of damage to the hydraulic parts.

Features
Cutting edge hydraulicsThe geometry of the impeller and the pump casing are optimized to achieve maximum efficiencyand the best suction capability.
FlexibilityThe option to choose between cast iron and bronze materias for the hydraulic parts in contactwith the pumped liquid allows N-N4 series pumps to be selected for use with different types ofliquids.
RobustnessThe mechanical structure of the hydraulic parts in contact with the pumped liquid are dimensio-ned to guarantee the maximum resistence to mechanical stress. Also the casing cover is provi-ded with wings that prevent turbulence in the area of the mechanical sea, increasing the reliabi-lity.
ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providing high reliabilityunder all operating conditions.

FlexibilityThe option to choose between cast iron and bronze materias for the hydraulic parts incontact with the pumped liquid allows C series pumps to be selected for use with differenttypes of liquids.
Solid partsThe open impeller allows for the passage of suspended solids in pumped liquid.
ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providing highreliability under all operating conditions.
