Sundyne Sealless Goes Submersible

Reduce Costs With an HMD Kontro Sealless Sump Pump


Eastbourne, UK – September 22, 2020 –Sundyne HMD Kontro has extended its range of vertical inline sealless pumps with the development of a sump pump variant. The new GSPVS, which meets the requirements of API 685 (as applicable to this style of pump) and is fully ATEX compliant, has been designed for use in tank farms for tank fuel transfer, as well as in oil and gas refineries, chemical and petrochemical processing plants.

The vertically mounted GSPVS pump provides all of the benefits of a magnetic drive pump in a compact package, using fewer parts with no seal systems for reduced cost operation. Composed of modules which can be joined to reach a total assembly length up to five meters / sixteen feet, the GSPVS is mounted on a base available to ANSI B16.5 or to customer specific requirements, including lifting points as standard. The modular construction uses a flexible jaw coupling to join drive shafts and to absorb misalignment, decreasing vibration and increasing life expectancy.

Greased for life ball bearings are used along the column, removing the need for lubricating or cooling the intermediate sleeve bearings using system fluid. The use of labyrinth bearing seals and a suction strainer avoids external contamination to maximize seal and lubrication life.

Sundyne HMD Kontro has more than twenty-five years’ experience in API applications and over a sixty-five year heritage in magnetic drive technology. It was the first pump manufacturer to develop a sealless pump.  With stricter demands for the safety and welfare of both personnel and the environment being imposed, sealless pumps are playing an increasingly important role. Sundyne HMD Kontro is continuously developing and extending its range, as improved magnet drive technology enables ever more efficient and powerful pumps to be built, widening the application scope of this versatile pump format.
