4 They depend onvarious factors such as temperature, conveyed medium, etc. and may not necessarilybe Important instructions for the screw pump- Never allow screw pumps to run Incorrect direction of rotation leads to pump Sufficient supply of fluid must always be Floating particles in coolant may damage the screw If high-pressure pumps are still to be used, a suitable fine-filter systemmust be installed upstream. If the cause of pump damage is excessive particlesand can be proven, the warranty is no longer valid- The size and concentration of a tolerable amount of particles depend on theparticle :ParticleParticlesize:concentration.

6 And for malfunctions- Close the piping Remove all hazardous Do not allow coolant to escape into the Depressurise Always wear protective clothing and protective gloveswhen handling hazardous TransportationRisk of injury- Do not stand beneath suspended Ensure that the carrying cable has a sufficient load Attach the cable underneath the motor (see Figure).- Make sure that the pump does not slide out of thetransport train suspension during The illustrations on this page areprovided as Assembly / Safety requirementsRisk of injury- Pump is not intended for use in areas where there is a dangerof explosions- Electrical operating equipment which is to be operated in potentiallyexplosive areas must be ATEX-approved and fulfil the relevant protectionspecifications.

7 These are identified by the symbol for explosion-proofoperating Installing the unit-Any installation location (motor facing downwards not permitted)-Insert submerge version KTS pump (1) including pump plate (2)into the corresponding aperture (3) on the coolant tankand secure using the mounting screws-When the delivery line is fitted tobase versions of KTS pumps (4)(dry installation), make sure that thepump fills Connecting the piping system-Connect the intake line, pressure line and excesspressure dispersion line as shown in the illustrationBack pressure should notbuild in the pressure limiting valvedispersion pipelines should not exerciseany strain on the pump-Avoid unnecessary changes in direction andchanges to the pipeline diameter-Do not select pipes with a nominal widththat is smaller than the pump s nominal pipe width-Clean all piping elements and fittings.

8 Remove any burrs and welding beads-Flange seals should not protrude inwardsPressure limiting valves-Protect screw pumps against excess pressure(never use without a pressure limiting valve)-The opening pressure of additional safety valves must be approx. 10% greater thanthe operating pressure of the pump-Check the function of pressure limiting valves after longer shutdown periods,replace any damaged components, if necessaryLeaking pressure limiting valves may damage the gauge-Briefly open shutoff valve on the pressure gauge to check the supply pressure,then close again.
