TWIN SCREW PUMPS
Positive Displacement Twin Screw Pump design as perManufacturer standard or comply with Rotary Positive Displacement API 676 latestedition. The construction eitherOne or Two Pairs of Screws,which operate without being in contact with each other, ensure a constant flow, pulsation-free, together with a high suction lift capability with very low NPSH values.
Horizontal Installation is supplied as standard while VerticalInstallation is supplied on request.
External supports and gears are supplied as Standard whileInternal supports and gears can be supplied on request, in case the pumped fluid is sufficiently clean and lubricating.
TWIN SCREW MAIN ADVANTAGES:
·Self-Priming
·Theyensure a constant flow, pulsation free
·Highsuction capability - the pump NPSHr being very low
·Verywell suited to pump fluids with low, medium, high and very high viscosity, sensitive to shear forces andturbulencethanks to the low of Internal Velocity given by the screw movement.
·LowNoise Level and Low Vibrations
·Thescrews are contactless thus wear out is minimized.
·Flowcan be reversed (reversibility) in low pressure applications, upon request
·EntrappedAir or Gas in the Liquid are tolerated up to 50-60% volume (multi-phase service on request)
·Capabilityof Dry Running for a limited period and in particular conditions
·CompactDesign and Dimensions
