Best cartridge seal supplier today? We 100% follow original and exquisite seal design concept to make sure the perfect performance applied in the machines. Our grundfos pump seals have passed various certifications like ISO, SGS, and CE. Precise and advanced machines are purchased for ensuring the width, height, thickness, and diameters of each part, or it may cause mechanical breakdown to a certain extent. Stainless steel is the main material adopted for the sealing frame, sealing joints, and so on, which is for the rust resistance and corrosion resistance of the product. The product can be easily installed in the machines and offers high resistance when working. Besides that, it has the excellent performance of high and low temperature resistance, so it can stay stable under the working temperature from -30C to 200C. See additional information on cartridge mechanical seal. The unit is fitted onto the pump shaft as a built assembly, and no further fitting is required. Cartridge mechanical seals are an attempt to over-come the fitting problems of conventional seals.

Besides that, being made of high-quality stainless steel and welded by the advanced machine, the product has no burr on its surface and gives people a strong feeling of smoothness. To ensure its superior performance, the product will be tested thousands of times for its high load resistance, good self-lubricating effect, good wear resistance, and good resistance to thermal cracking. Thanks to the small coefficient of liner expansion of the materials, the product can resist heat deformation and enjoy dimensional stability. It has high size precision, which perfectly matches the dimensions of the Nissin Pump.

For better satisfying the needs of customers, the product can be provided with different shaft sizes ranging from 24mm to 100mm.
