Sundyne is a US manufacturer of centrifugal pumps and compressors for chemical, refining, petrochemical and power plants. The headquarters is in Arvada (Colorado, USA). Since 2025 the company has been part of Honeywell. Steiner Ukraine is the official representative of Sundyne in Ukraine: we select pumps for the process conditions, supply equipment and spare parts, and provide service.<\/p>\n

How an integrally geared Sundyne pump achieves high head<\/h2>\n

In Sundyne Integrally Geared pumps the motor drives the input shaft of a speed-increasing gearbox. The gearbox raises the speed, so the impeller on the high-speed shaft turns much faster than the motor.<\/p>\n

The head of a centrifugal impeller rises with rotational speed. As a result, one impeller delivers the head that a conventional pump needs several stages to reach.<\/p>\n

The hydraulics are matched to the specific duty point by combining the impeller, diffuser and inducer (a screw-type wheel at the inlet). This sets the efficiency, curve shape and required net positive suction head (NPSH). Why NPSH matters is explained in the article \u201cPump cavitation: symptoms, causes and how to eliminate it\u201d<\/a>.<\/p>\n

How a sealless magnetic drive pump works<\/h2>\n

ANSIMAG and HMD Kontro pumps and the LMV-801S model have no mechanical shaft seal. Torque from the motor is transmitted through a magnetic coupling. The outer magnet rotor turns outside the casing, the inner one in the pumped liquid. A sealed containment shell separates them.<\/p>\n

The liquid stays entirely inside the casing. There is no seal to wear and no seal support system.<\/p>\n

The main risks for this type of pump are dry running, low-flow operation and magnet decoupling. A power monitor in the motor control centre protects against them: it tracks power consumption and trips when it leaves the set limits. For additional protection, the pump can be fitted with secondary containment in case the containment shell is damaged.<\/p>\n

How seals for aggressive media differ is described in the article \u201cHow seals differ for pumps handling aggressive liquids\u201d<\/a>.<\/p>\n
