spindle pump

The principle of the spindle pump is based on the movement of a spiral spindle inside the pump housing. This pump is suitable for pumping viscous and heavily polluted liquids, such as sludge, oil emulsions, mud, partially solid substances and the like.

The main part of the spindle pump is the spindle, which is shaped like a spiral. The spindle is placed inside a fixed housing and has the ability to rotate around its axis. When the spindle rotates, a tight space is created between its surface and the housing walls, which moves from the intake to the outlet opening.

During operation, the liquid in the housing is gradually pumped along the entire length of the spindle. Due to the spiral geometry of the spindle, the liquid is shaped and drawn during the passage through the pump, which enables efficient pumping of viscous substances and solid particles.

The spindle pump offers the advantages of a high flow rate and the ability to pump heavily polluted liquids. Its design allows working with relatively small flows and high pressures. It is used in several branches of industry, for example in wastewater treatment plants, when pumping oil emulsions, in the food industry and in many other applications where it is necessary to pump viscous and polluted liquids.
