∙
The pump may only be operated with personal protection insulation under temperature.
∙
The sufficient insulation of heated pumps is under the responsibility of the operating company.
∙
Minimum insulation thickness in [mm] for the insulation with a thermal conductivity of λ=0.09 W/mK:
T
Operation, max.
T
Ambience, max.
50 °C
40 °C
30 °C
20 °C
The thermal conductivity of λ=0.09 W/mK, for instance, corresponds to that of glass wool with an appar­
ent density of 100 kg/m³ and a medium temperature of 300 °C. The insulation must be flameproof.
If the required insulation thickness cannot be achieved in certain cases, an insulating material having a
lower thermal conductivity must be used.
∙
The control of the electrical heating must be adjusted so that during the heating-up time the boiling
temperature of the sealing liquid is never reached (slow heating up required).
∙
Install the electrical heating so that a sufficient heat transfer is given between heating and pump. The
radiator must firmly rest against the pump body. During the operation, this must be checked regularly.
Any deformation of the electrical heating must be avoided.
∙
Install the temperature sensor so that a sufficient heat transfer is given between sensor and pump.
Use thermal conductance paste.
∙
When working at the electrical heating, it must be disconnected from power and protected against un­
intentional restart.
1.9 Installation / Machine Specific Safety Instructions
∙
The values specified in the pump data sheet (see information in Chapter 7.) refer to the mechanical
rigidity of the pump.
It therefore lies in the responsibility of the operating party to carry out appropriate tests with the used
pump media to determine the allowed operating values and to ensure that neither the media them­
selves nor the media-specific operating conditions may pose any risk to persons or equipment.
∙
The compatibility of discharging, heating, flushing, and sealing media with the static seals - and if ap­
plicable - shaft seals and the pump material must be ensured.
If necessary, consult the Barmag pump service regarding this matter.
∙
Pumped and sealing media may be hazardous to health.
Wear appropriate protective clothing.
∙
The ignition temperature of the discharging and sealing medium must be at least 50°C higher than the
pump's operating temperature.
∙
It must be ensured that inflammable media may not drip onto areas where an ignition may occur. If
necessary, place a protective pan below the pump set. This pan must continuously be monitored for
leaking liquid.
∙
A suitable sealing liquid must be used that does not boil under operating conditions.
∙
Be careful when filling in and draining hot materials hazardous to health in or from the sealing cham­
ber.
∙
Uncontrolled pump operation can lead to suction and delivery pressures that damage the pump or line
and endanger the personnel. Therefore, it is absolutely necessary to monitor the suction and delivery
pressures. The allowed pressures can be derived from the pump data sheet (see information in
Chapter 7).
