• Heating multiple dwellings• Air conditioning

Many industrial and agricultural applica-tions. • Heating greenhouses• Transferring antifreeze• Circulating iced water.

RANGE OF USEFlows up to: 200 m3/hManometric head up to: 52 mMaximum working pressure: 10 barTemperature range: – 10° to + 110°Cnominal diameter ports: 32 to 100MEI* of reference: ≥ 0,10*Minimum Efficiency Index

SINGLE AND DOUBLEIN-LINE PUMPS

Heating - Air conditioning50 Hz

APPLICATIONS

ADVANTAGES• Low electrical consumption.• Mounts directly onto horizontal or ver-

tical pipework.• Not coupled: no need to align the

shafts.• Device to de-aerate the mechanical

seal.• Easy and quick to install.• Practically zero maintenance.

JRN • A backup pump permanently available.• The two pumps can be operated in

parallel to increase the flow.• Manual or automatic pump switchover

by MGP box .

• LRN- JRN: vertical motors

DESIGN• Hydraulic part- Centrifugal, single-stage.- Intake and outlet ports in line.- Flanged pump housing with ports for

connecting pressure gauges.- Bearing lantern linking pump to motor.- Dynamically balanced impeller, mounted

directly on the shaft of the motor.- Waterproof mechanical seal.

JRN- Double pump in one housing.- The two pumps are hydraulically separated

by silent-operating valve.

• Motor- IE2- One end of shaft lengthened.- The rotor shaft’s guide bearings selected for

silent operation.

Special mechanical seal for 20 to 50% antifreeze if temperature is above 40°C:contact us for further details.

PARTICULARITIESa) Electrical P2 = 3 kW : three-phase 400 V Y 50 Hz three-phase 230 V ∆ 50 Hz P2 ≥ 4 kW : three-phase 400 V ∆ 50 Hz b) Installation Mounted directly onto horizontal or vertical pipework or on massif.The system must provide protection of the pump against bad weather and frost (do not expose to direct sunlight or rain). c) PackagingPumps delivered with backflange gaskets. d) Maintenance Repair: see the list of spare parts available on the plan and cross-section.

ACCESSORIES

Sealing capRound backflanges to solder on Set of support legs Pressure measurement kit Slave switch of protection motor (LRN) Control and protection box (JRN) Shut-off valves Anti-vibration sleeves Non-return valves
