    1 Introduction 1.12.4 Paint All pumps are delivered from the plant without external painting/coating. However, if a surface coating is desired, attention should be paid to the following note. DANGER! If it is necessary to use an external surface coating, ensure the following to prevent dissemination of brush discharges: the total thickness of the paints used does not exceed 2 mm in conjunction with the intended classification in explosion class IIA and IIB and 0.2 mm with IIC.

  • Page 17: Improper Use/Fault

    The partly listed faults refer to the potential ignition sources in accordance with the ATEX directive as well as EN1127-1. The most relevant types of ignition sources for gear pumps from Scherzinger are "hot surfaces", "mechanically generated sparks" and "static electricity”.

  • Page 18: Danger From Dry Running Of The Pump

    1 Introduction 1.13.2 Danger from dry running of the pump DANGER! Without fluid, the pump runs dry. As the sliding surfaces are not lubricated the gears and bearing bushes become hot and are thermally and mechanically destroyed. If there is no fluid in the containment can, the heat induced by eddy current losses can also not be dissipated, resulting in the overheating of the pump.

  • Page 19: Danger From Overpressure In The Pump

    1 Introduction 1.13.4 Danger from overpressure in the pump DANGER! An operation with closed shut-off devices suction/pressure pipe is not permit- ted! Due to closed shut-off devices or closed pipes, there is the risk of very high surface temperatures, after even a short period of time, caused by fluid overheating in the interior of the pump.

  • Page 20: Danger From Particles/Foreign Matter In The Fluid

    1 Introduction 1.13.5 Danger from particles/foreign matter in the fluid DANGER! Inadmissible operating conditions can arise from foreign matters in the fluid and result in the premature wear of pump components, so that very high sur- face temperatures can develop after a short time. Prefilter We recommend the following monitoring measures: - Filter with contamination indicator.

  • Page 21: Danger From Operation With Too High Of A Speed

    1 Introduction 1.13.7 Danger from operation with too high of a speed DANGER! By exceeding the given speed, the danger of inadmissible heating above the maximum permissible surface temperature occurs as well as a fire risk in the presence of an explosive atmosphere. The pump must only be operated with the speed specified in the technical data! 1.13.8 Danger from potential difference...

    2 Safety Instructions 2 Safety Instructions The pump is a quality product manufactured according to the accepted rules of tech- nology. The pump left the manufacturer’s factory in a technically and operationally safe condition! However residual risks are present - during installation/dismantling, - during commissioning/decommissioning, - during operation, and - during maintenance/cleaning.

  • Page 30: Danger From Hot Parts

    2 Safety Instructions 2.2 Danger from hot parts DANGER! If the pump is operated in a closed casing, it must be ensured that this does not overheat! We recommend the installation of a temperature sensor for automatic mon- itoring. If danger from hot parts arises, you have to protect these parts from being touched by means of a protective construction.

  • Page 31: Danger From Magnetic Fields

    2 Safety Instructions 2.4 Danger from magnetic fields DANGER! The magnetic coupling contains permanent magnets. Danger for people with active or passive implants can arise from the magnetic field! People with pacemakers as well as those with active or passive implants may not enter into the area of the magnetic field.

  • Page 32: Danger From Fluids

    2 Safety Instructions 2.5 Danger from fluids DANGER! The fluids can evoke risks of injury and poisoning. When working on the pump, personal protective equipment must be worn. The definition of protective equipment is, amongst other things, dependent on the fluid and must therefore be newly determined for every application by the operator and made available for the personnel.

  • Page 33: Transport And Interim Storage

    After having received the pump, you must immediately check the pump for transport damages. If you detect any damage, you must inform the responsible forwarder of this and Scherzinger Pumpen GmbH & Co. KG 78120 Furtwangen / Germany im- mediately.

  • Page 34: Conserving The Machine For Storage After Operating/Flushing The Pump

    3 Transport and interim storage 3.3 Conserving the machine for storage after operating/flushing the pump Depending on the fluid transported, the pump must be prepared differently for stor- age. If no toxic or aggressive fluids were transported, flush the pump briefly with water without a differential pressure rise at a low speed.

    4 Mode of operation/Functional description 4.2.2 Design and commissioning of pressure relief valve (only for 50X5-...-B-...) Figure 4.2-2: Pressure relief valve The pressure relief valve (bypass valve) is a safety valve and serves to limit excess pressure to protect the pump and the system. When addressing the valve, the fluid is internally led back from the pressure to the suction side and potential damages to the system or the pump head are avoided.
  • Page 40 4 Mode of operation/Functional description Figure 4.2-3: Adjustment of the pressure relief valve Proceed as follows for adjusting the pressure relief valve: Loosen the clamp screw (38) by a quarter turn (counter-clockwise). Adjust the valve by turning the overpressure valve screw (39) - to the left (counter-clockwise) = reduce the opening pressure, - to the right (clockwise) = increase the opening pressure.
  • Page 41 4 Mode of operation/Functional description Dismantling Take the pump or the already dismantled cover (2). Open the clamp screw (38) with a spanner by a quarter turn. Unscrew the adjusting screw (39) until it is no longer in the thread engagement, then pull it out by hand.
