2. SAFETY
Read this data sheet carefully before installing and starting up. Pay
special attention to the points concerning the safety of the
equipment for the intermediate or end user.
2.1. Symbols used in the manual

affect safety.
3. TRANSPORT AND STORAGE
When taking delivery of the equipment, check that it has not been
damaged in transit. If anything is found wrong, take the necessary
steps with the carrier within the allowed time.
If the equipment delivered is to be installed at a later time,
store it in a dry place and protect it from impacts and
outside influences (moisture, frost, etc.).
4. PRODUCTS AND ACCESSORIES
4.1. The pump
Monobloc, centrifugal, single-stage
LRL : Single model
JRL : Dual model with nonreturn valve on discharge to allow
switching between two pumps.
The suction and discharge ports are IN LINE.
The motor, with a lengthened shaft end, has built-in protection by a
thermal overload probe.
The bearings are packed with a high-performance grease and
lubricated for the life of the motor.
Speed : 1450 or 2900 rpm
Winding : for 230/400-V three-phase power
Frequency : 50 Hz
Insulation class : F
Protection index : IP54
The shaft has a maintenance-free self-lubricating mechanical seal
with carbon/silicon carbide/drinking water gasket friction faces.
4.2. Accessories
The following are available for an extra charge:
• Circuit-breaker (LRL)
• Y1200 control box (JRL)
• Weld-on round counter-flanges, PN 10
• Isolating valves
• Anti-vibration sleeves
• Blanking cover (JRL)
• Pressure gauge kit
• Baseplate for ND 65 and 80 models
5. INSTALLATION
5.1. Installation
Install the pump in a place that is easy to reach and protected from frost.
: 10 bar
: -10 to +110°C
: ISO PN 10 (NF E 29203)
The pump may be connected directly to the pipe or installed on a
concrete foundation block.
- Direct mounting on the pipe is possible in all positions except
motor down (see FIG. 1).
If the JRL pump is installed on a horizontal pipe, with the
motor centrelines horizontal, it will be necessary to switch
operation between the pumps from time to time to avoid the
formation of an air pocket at the high point of the casing.
- Installation on foundation with pump baseplate (ND65 and 80 option)
and attachment by anchor bolts (see FIG. 2 for installation).
- The volume of the foundation block must be commensurate with
the weight and size of the pump.
- If there are several pumps in the installation, they can be installed
on the same foundation.
- Place an insulating material (reinforced rubber or cork) under the
foundation block to cut down vibrations.
5.2. Hydraulic connections
By PN10 weld-on round counter-flanges (not supplied) matching the
diameter of the ports.
- Connect the suction and discharge pipes, with the (optional) PN
10 counter-flanges with gasket contact faces, to the pump.
Note the direction of flow of the pump casing (look at the arrows on
the flanges).
• Place isolating valves after both ports to facilitate removal of the
pump and anti-vibration sleeves and cut down stresses and
circulation noise.
JRL: After the discharge flange, fit a sleeve or a diffuser before the
isolating valve to allow work on the nonreturn valve without
removing the pump (200 m long).
Pressure measurements: there are two 1/8" dia. ports on the suction
and discharge flanges for connection of pressure gauges.
5.3. Electrical connections
The electrical connections and checks must be made by a
licensed electrician and comply with applicable local
standards.
• Protection of motors:
- LRL, by a 439D circuit-breaker
- JRL, by a Y1200 control box, which also allows automatic
switching between thepumps.
Power supply
• Use a four-conductor cable (three phases + earth) to connect
230- or 400-V three-phase line power to the terminals of the motor;
DO NOT forget the earth terminal (see FIG. 3).
The power cable must not touch the pipe or the pump.
Thermal overload probe (one per motor)
Must be connected.
Overheating of the winding (because of frequent starting,
overloads, etc.) causes the electrical circuit to open; it closes
automatically when the temperature returns to normal.
The unit can be reset manually using the pushbutton on the circuit-
breaker (439D) or the pushbutton incorporated in the Y1200 control box.
Electrical diagrams showing the connection to the circuit-breaker
(439D) or to the Y1200 control box are supplied with the units (or see
FIGS. 4 and 5).
6. STARTING UP
6.1. Filling, degassing
Never operate the pump dry, even momentarily.
- Close the discharge valve and completely fill the pump and the
suction pipe.
- Open the bleed(s) on the bearing cages and wait for a steady
stream of water to flow out before closing.
