Kosaka - Twin Screw Pump 

  • For all liquids from low to high viscosities and corrosive.
  • Self Priming
  • Non pulsating flow
  • High suction
  • Low noise
  • Compact and space saving design
  • Less wear thanks to non contact between screws

Applications in Thermal Power Plants

  • Heavy & Crude Oil Transfer Pump
  • Coal Oil Mixture (COM) & Coal Water Mixture (CWM) Transfer Pump
  • Orimulsion Trans Pump
  • Heavy & Crude Oil Burning Pump
  • COM & CWP Burning Pump
  • Orimulsion Burning Pump

Kosaka - Three Spindle Screw Pump 

  • Simple construction
    Rotating elements are only one power rotor and two idler motors. Construction is simple.

  • Trouble free operation
    Reasonable construction results trouble free running and easy handling in the field.

  • Low noise
    As rotating elements are only three rotors and comparatively small, and also idler rotors are rotated by liquid pressure, natural, smooth, low noise running is ensured even at high revolution and pressure.

  • Low pulsation and agitation
    Liquid enclosed into chambers sealed by rotors and sleeves is transferred continuously from suction to discharge without pulsation and agitation.

  • Long service type
    As pressure acted to rotating elements is balanced completely, rotors and sleeves are not disturbed by obstructed pressure, and also, as idler rotor are revolved by liquid pressure, and lubricated by liquid pumped, there are no direct touches among rotor and sleeve. Therefore wear is kept extremely low.

  • High operating efficiency
    There is no direct transmission of power to idler rotors and internal pressure acted to rotating elements is balances, so friction loss is very small. And also, internal leakage loss is kept low with precise machining of rotating elements.

  • High suction lift
    As liquid is transferred to thrust direction continuously without agitation and also sealed chambers works as in finit piston, high suction lift is ensured easily without cavitation.

  • Small starting torque
    As inertia of rotating elements is small, starting torque is small.

  • Compact and large capacity
    Since high speed driving is possible for a pump, it is compact also at large scale.
