Booster Pump - Twin Screw Pump

Specification of Booster Pump - Twin Screw Pump

TWIN SCREW PUMP – BOOSTER PUMP

3P PRINZ Positive Displacement Twin Screw Pump design as per
Manufacturer standard or comply with Rotary Positive Displacement API 676
latest edition.  The construction either
One 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 NPSHr values.

Horizontal Installation is supplied as standard while Vertical
Installation is supplied on request.

External supports and gears are supplied as Standard while Internal
supports and gears can be supplied on request, in case the pumped fluid is
sufficiently clean and lubricating.

TWIN SCREW MAIN
ADVANTAGES:

·        
Self-Priming

·        
They ensure a constant flow, pulsation free

·        
High suction capability - the pump NPSHr being very low

·        
Very well suited to pump fluids with low, medium, high and very
high viscosity, sensitive to shear forces and turbulence thanks to the low of
Internal Velocity given by the screw movement.

·        
Low Noise Level and Low Vibrations

·        
The screws are contact less thus wear out is minimized.

·        
Flow can be reversed (reversibility) in low pressure applications,
upon request

·        
Entrapped Air or Gas in the Liquid are tolerated up to 50-60%
volume (multi-phase service on request)

·        
Capability of Dry Running for a limited period and in particular
conditions

·        
Compact Design and Dimensions
