Sealless Internal Gear Pumps for Leak-Free Process Transfer
Kweng sealless internal gear pumps combine the performance advantages of internal gear pumping with the safety of magnetic drive containment. The pump uses a gear-within-gear principle for smooth transfer while the containment shell hermetically seals the liquid inside the pump. This helps achieve a very high level of liquid containment by removing traditional shaft seals that are commonly used for dangerous, hard to seal or expensive fluids.
As an internal gear magnetic drive pump, this range is well suited for industrial users who need stable transfer, reduced leakage risk, improved process safety and dependable handling of specialty fluids. It is particularly relevant where product loss, emissions or seal related maintenance must be minimized.
These sealless internal gear pumps are suitable for both thin and high viscosity liquids and are widely used in petrochemical, resin, adhesive, solvent, polymer and specialty chemical processes. Their leak-free design makes them a strong choice for domestic India projects as well as international B2B industrial buyers.
