These screw pumps are volumetric self-priming pumps suited to handle oils and liquids with a minimum lubricating quality. The design simplicity makes these screw pumps intrinsically reliable and ...

“This is the Wood Screw Pump,” Becker says. “There’s no wood in it, it’s not made out of wood at all. This is named after the person who invented the design. A. Baldwin Wood.” Albert ...

The ScrewLine SP250 oil-free gascompression screw-type vacuum pump supports applications that require varying pumping speeds in the same plant. An alternative to oil-sealed piston vacuum pumps ...

GV oil-sealed rotary-screw vacuum pumps combine oil-sealed rotary screw technology and advanced screw design. These systems operate in 1 to 500-mbar pressure ranges. Two screw elements rotate at ...

Designed for transfer and circulation of transformer insulating oil, the IMO 3-screw design features low/vacuum inlet pressures. Series 3D pumps, available in 19 different displacements ...

The design of these low-maintenance units prevents the possibility of pollutants being released into the medium. He adds that BMG’s SEIM range encompasses three spindle screw pumps, for ...

The design incorporates a third idler rotor which suppresses vibration and noise when the pump is lightly cavitated. All of these three-screw pump solutions from IMO feature suction lift ...

A Rotterdam-based company might have found a solution, though, with a unique turbine design partially based on Archimedes’ famous screw pump. Instead of moving water, the Liam F1 Urban Wind ...

But if you want to move water up, you need a pump. The ancients used what we call Archimedes’ screw to raise water. But a Wirtz pump as [Steve Mould] shows in the video below, is another kind of ...
