Technical Features of Seepex BN5-6L Stator

The Seepex BN5-6L stator is a highly efficient screw pump component designed specifically for conveying viscous and non-viscous fluids. Its main function is to work with the rotor to push the fluid from the feed port to the discharge port. Its special geometry and material selection enable the stator to maintain excellent performance under high pressure and high flow conditions.

The BN5-6L stator is usually made of highly wear-resistant rubber or polyurethane, which has excellent corrosion and wear resistance and can provide long-term reliability in different working environments. In addition, the design of the component also takes into account the problems of thermal expansion and temperature changes, ensuring stability under extreme conditions.

SEEPEX open hopper pumps are used to discharge thickened and dewatered sludges for onward processing. SEEPEX can also directly mount pumps under storage silos that have a capacity to backmix to control sludge dry solids content.

Pump stators are usually made from a variety of rubbers or plastics, their shape forms the shape of the pump rotor, they work together to ensure that fluid movement is always forward, these parts act as internal valves within the pump preventing the fluid from returning to the inlet (positive displacement).

Generally, the frequently used types are steel with painting or stainless steel. This rule applies to most progressive cavity pump brands like NETZSCH, MONO, SEEPEX, ALLWEILER, etc. However, the lining materials are usually rubber-like elastic.
