    Operation with closed shut-off valves Mega pumps can operate harmlessly for several days with closed shut-off valves and at any speed. It is recommended to set the control mode to minimum speed to reduce energy consump�on. There is no minimum flow requirement. The pump inlet and outlet valves must not be closed at the same time to prevent pressure build-up.

    In addi�on, the pump can be used in the following systems: •systems that u�lize geothermal energy; •solar hea�ng systems. Pumped fluids The pump is designed for pumping clean, non-viscous, explosion- proof, solids-free or long-fiber-free liquids that are chemically neutral to the pump materials.In hea�ng systems, water must meet the requirements of local water quality standards for hea�ng systems.

  • Page 13: Principle Of Action

    Guideline 7.Principle of action The opera�ng principle of the Mega series pumps is based on increasing the pressure of the liquid moving from the inlet to the outlet. The pressure increase is achieved by transferring mechanical energy from the motor sha� coupled to the pump sha� directly to the liquid by means of a rota�ng impeller.

    In some cases it may be necessary to install condensate collec�on and drainage devices. Mounting pump The Mega series includes pumps with flange and threaded connec�on. These installa�on and opera�ng instruc�ons apply to all versions, however, a general descrip�on of pumps with flanges is provided. In case of differences, the descrip�on for the version with threaded...

    Thermal insulation When carrying out thermal insula�on measures it is forbidden to apply thermal insula�on to the pump head. Fig. 7 Thermal insula�on of the Mega pump Warning Provision must be made measures to protect personnel from injury and prevent equipment damage from fluid leaking out when the stator is unscrewed.
  • Page 18 Warning The pump must be connected to an external switch, minimum contact gap: 3 mm on all poles. Earthing or grounding must be used as protection against electric shock in case of indirect contact. Versions with plug connection: In case of insulation damage, the short-circuit current can be a pulsating direct current.
