This company has introduced the new S Series of screw pumps (photo) for conveying challenging fluids. These rotary positive-displacement pumps are ATEX-certified for use in explosive or dangerous environments. They are self-priming, and deliver a constant flow with low pulsations, even at considerably different pressures and volumes, says the manufacturer. Twin-screw pumps can be a good option for conveying challenging multiple-phase fluids containing oil, gas and water. In a variant of the S Series, the twin-screw pumps employ timing gears to transmit the power from the power screw shaft to the idler screw shaft to reduce the possibility of wear when pumping abrasive materials, or where special materials of construction dictate non-contacting operation. — Maag Industrial Pumps, Oberglatt, Switzerland
