High Speed Diesel Pump - Twin Screw Type

Specification of High Speed Diesel Pump - Twin Screw Type

Twin Screw
Rotary Pump API 676

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 timing gears type
is supplied as Standard while Internal Timing gears are supplied on request, in
the case of the pumped fluid is sufficiently clean and lubricating.

 TWIN SCREW MAIN
ADVANTAGES: 

·        
Self-Priming

·        
They ensure a constant flow, pulsation free

·        
High suction lift capability - the pump NPSHr being very low up to
1.5 m

·        
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 contactless 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
