3.1

Piping system

Chapter 3

3.1.1 Installation plan

ATTENTION •

• •

• •

• •

•

• •

If the pump is mounted vertically, suction lift operation is not permitted as the ventilation of the isolation shroud then cannot be ensured. Pay attention to the arrows at the pump branches indicating the flow direction. The nominal widths of the pipelines must not be smaller than the nominal widths of the corresponding pump branches. All pipelines must be cleaned prior to installation of the pump. The pipelines must be supported in order to avoid distortions of the pump components (danger of breaking of the pump components). Avoid abrupt transitions of cross section and changes of direction. Unequal nominal widths are to be compensated by excentric transition pieces. The extension of the cross section has to be made downward in order to avoid the formation of air pockets in the pipeline. In front of the suction branch of the pump a flow normalizer has to be arranged; it shall have the diameter of the nominal width of the suction branch and the length of 15 times the diameter of the suction branch. This secures favourable inflow conditions. The flow velocity in the suction line or inflow line, respectively, must not exceed 2 m/s. The pipelines are to be laid in such a way that thermal expansion in the pipe system does not have any effect on the pump branches.

3.1.2 Suction line or inflow line, resp. The suction line must ascend to the pump. The inflow line must slightly descend to the pump. Gate valves in the suction line or inflow line must be kept completely open during start and operation of the pump.

Suction head operation

Suction lift operation

If dirt particles are to be expected either from the pipework or from the pumping medium, a filter must be installed in the pipeline. The free section of the filter must have at least the triple section surface of the nominal width of the pump. Mesh size = 0,1 mm.

3.1.3 Discharge line In order to adjust the pumping data a gate valve is to be installed behind the pump. If non-return elements are applied they shall have the property of closing smoothly. Prevent pressure surges.

3.1.4 Installation of an orifice

03DE2.DOC

- Q-max-orifice In order to avoid the exceeding of the admissible output a Q-max orifice should be fitted into the discharge line (see installation plan). This secures sufficient lubrication of the sleeve bearings and the safe dissipation of the heat due to energy losses of the magnetic coupling. Subject to technical alterations Copyright Sterling SIHI GmbH

Planning of the installation

Page 2 of 2

- Q-min-orifice or overflow valve, resp. In order to avoid that the output goes below the required minimum, an overflow valve or a Q-minorifice should be fitted (see installation plan). This secures sufficient cooling of the magnetic coupling.

3.1.5 Pressure control For the proper pressure control two measuring points are to be provided at the pipelines, one before and one behind the pump. (see installation plan).

Chapter 3

damage to the magnetic coupling or to the pump is prevented.

3.3.2 PT 100 The PT 100 is a resistance thermometer for the control of the temperature of the isolation shroud. It is screwed on the pump by a threaded connection. The switch-off temperature is to be adjusted by 10 °C higher than the operating temperature. In case of variable temperatures the control values should be inquired at Sterling SIHI.

3.3.3 Level transmitter 3.2

Electrical connections

For the drive motor a mains connection is required which complies with relevant regulations and laws. The start up of centrifugal pumps with star-delta-switch normally leads to a higher power consumption during the switch to delta than the direct start up in delta connection. The accelerating torque during the switch from star to delta connection is very high, so that a desynchronisation of the magnetic coupling might happen. Therefore a direct start up is advantageous, especially with pumps with big moments of inertia. Normally this has to be approved by the local power supplier. If the direct switch on in delta connection is not allowed, a soft starter (see point 3.3.4) might be necessary.

3.3

In order to ensure that the pump only can be run with a sufficient liquid level, a level transmitter should be installed. It must guarantee that a sufficient liquid quantity will always be available. Therefore it has to installed in the pipework above the pump.

3.3.4 Soft starter When selecting the magnetic coupling, the decision to apply a soft starter may result in the fact that a coupling with smaller nominal torque, i.e. a cheaper one, can be applied. The use of a smaller coupling also results in lower eddy current losses. Therefore the power consumption of the pump is lower and the efficiency increases.

Accessories

For this pump the following accessories are available: • Load detector for the control of the motor power absorption • Temperature probe PT 100 for the control of the temperature of the isolation shroud • Level transmitter for the protection against dry operation • Soft starter

3.3.1 Load detector The load detector measures the power absorption of the drive motor. If the absorption becomes too high, e.g. by blocking of the rotor or decreases by desynchronization of the magnetic coupling, the motor is switched off automatically. Thus a 03DE2.DOC

7.4.1 Oil lubricated ball bearings The pumps are delivered without an oil-filling. The oil-level is controlled by a constant level oiler. Therefore the pump has to be installed horizontal. In every case, also at the first filling, the oil has to be filled in the flapped back oil tank. After reflapping the oil tank the oil flows into the bearing bracket. This procedure has to be repeated until the oil does not flow out of the oil tank anymore. Then the correct oil level is reached. With new bearings, the oil shall be renewed after about 200 h of operation. After this renewing of the oil, the oil shall be renewed acc. to the following table. light duty

38.10 by using the screws 90.11. During the assembly of the bearing carrier 38.10 to the covers 16.00 and 16.01, the correct position of the bores for the partial flow has to be observed. The position of the bearing carrier 38.10 controls the partial flow and the pressure-level in the rear wear ring of the impeller. By turning the bearing carrier on 90° two different positions and therefore two different values of partial flow can be adjusted. At small differential heads and low axial thrust position 1 will be chosen to ensure a sufficient cooling and lubrication flow. At high differential heads, high axial thrust or when NPSH-problems occur, position 2 will be chosen. position 1: The bearing carrier 38.10 has to be assembled in a way, that the two big bores for the partial flow (∅ 9mm) are placed on the horizontal axis, and are congruent to the bores in the covers 16.00 and 16.01. Therefore the partial flow is led to the backside of the impeller via these two 9mm-bores. position 2: The bearing carrier 38.10 has to be assembled in a way, that the two big bores for the partial flow (∅ 9mm) are placed on the vertical axis. Then the small bore for the partial flow (∅6mm) is placed on the horizontal axis congruent to one of the 9mm-bores in the covers 16.00 and 16.01. Therefore the partial flow is led to the backside of the impeller via this 6mm-bore. The following table shows, which positions have to be chosen for the different pump sizes. Pump size

Technical Data

Flange connections and hydraulic data acc. to DIN EN 22858 / ISO 2858 (chemical standard pump) temperature of the pumping medium: -40°C up to 180°C when the temperature of the pumping medium is lower than 0°C, the standard pump with the closed bearing bracket has to be used. The bearing bracket has to be sealed against the flange for the can (81.71) by using Soft PTFE-Cord-sealing material. By doing so, the entrance of air humidity in the area of the outer magnet and isolation shroud is prevented. Therefore the freezing of the condensated air humidity during the times the pump is not running will not happen in such an amount, that the outer magnets freezes to the isolation shroud. Pumps with an open bearing bracket can be used for medium temperatures up to max. 300°C. (designation of this type: see table in chapter 2) Surface temperature:

The surface temperature of the pump will be very close to the temperature of the pumping medium. Especially in areas with defined temperature class regarding the safety against explosions, measures have to be taken to assure, that the surface temperature of the pump does not exceed the permitted temperature.

kinematic viscosity:

To ensure safe operation of the pump, the kinematic viscosity of the pumping medium has to at least 0,3 mm²/s and has to be lower than 300 mm²/s. In any case, the viscosity has to be kept in mind during the selection of the drive and of the magnetic coupling. In some cases also lower viscosities than 0,3 mm²/s can be handled. Please ask Sterling SIHI for further information.

Casing pressure:

PN 16 or PN 25 (designation of the different types see table in chapter 2) Depending on the temperature of the pumping medium, the admissible casing pressure may decrease. This is shown in the following diagramms. pressure - temperature limits casing material: GGG-40.3 (1B, 1E, 1R, 1U)
