The Marine Screw spindle pumps are positive displacement rotary type pumps. The main working parts of the pumps are three helical spindles and the pump housing. The helical spindles or screws can be compared with a gear having a very long, curved tooth, or with a piston pump with an indefinite numbers of pistons.
Technical data:
CapacityUp to 3300 l/min
HeadUp to 80 bar
Viscosity12 - 800 cst
TemperatureCast Iron up to 180°C
Steel case up to 260°C
Advantages:
The pumped medium is transported axially without turbulence and mixing, thus making possible pumping of very viscous fluids without foaming. The working volume of the pump remains unchanged and moves from the suction to the discharge chamber, ensuring in this way a continuous rate of discharge. Noiseless operation, long service life and high overall efficiency.
