Pump Description Blackmer S-series pump is a rotary positive displacement pump. We have two categories: Twin Screw Pump and Triple Screw Pump. Twin Screw Pump can handle most of the fluids (with or w/o particles, with or w/o gas, lubricated or non-lubricated). Triple Screw Pump can handle lubricated fluid without solid particles.
Twin Screw Pump The key components of Twin Screw Pump: Pump casing, liner, bearing housing, driving & driven screw, timing gear, gear box, bearing and mechanical seal. Standard Bearings- SKF Standard Mechanical Seals- John Crane (Twin) and Eagle Burgmann (Triple) Our double suction has a pair of screws on each shaft
Working Principle With the pump running, the screws on the shafts are meshed and form a sealing chambers with the pump casing (liner). The fluid is moved axially, from suction end to discharge end.
Screw Pump Benefits Self priming and line stripping is possible Pump flow rate is proportional to speed Wide range of applications / fluids Direct drive without gear reducer is typical High viscosity is possible Low noise level Compact structure available Repairable (maintenance)
Screw Pump Benefits Highest flowrate achievable by a rotary PD pump High tolerance for entrained air and other gases Low internal velocities, minimal shear Low NPSH Requirement Low Pulsation flow No metal-metal contact (with timing gear)
Construction Features Liner option for some models/series Specific model for high temperature and/or double seal Different mounting possible (horizontal or vertical) Built according customer requirement Different material of construction possible even according API676 specifications with deviations Different Sealing Arrangements Possible
