D Pump

SERIES 'D' Magnetic Coupled Pumps are seal-less, providing for maintenance-free and "leak-proof" operation. The magnetic coupling acts as a clutch to provide overload protection. The broad range of construction materials allows for a variety of applications and service with most corrosive solutions. The impeller magnet assembly floats in the radial magnetic field set up by the motor driven external drive magnet. The impeller is designed to deliver the maximum flow and pressure utilizing the available strength of the synchronized magnets. The standard diameter impeller is suitable for waterlike liquids to 1.1 specific gravity. Liquids having a higher specific gravity can be pumped if the overall diameter of the impeller is reduced, the outlet flow is restricted,or the restrictions from a filter or other head loss is sufficient to keep the impeller magnet in synchronization. Pump materials of construction are as specified, all of which include a fluoride resistant ceramic spindle and thrust washer. Casing 'O' ring is FKM and external fasteners are SS. Standard impeller is designed to pump solutions having a specific gravity up to 1.1. (See flow curves.) For solutions having a higher specific gravity, up to 1.8 maximum, a trimmed impeller is required. Flow rate and TDH will be proportionately reduced. Refer to impeller trim chart, specify impeller diameter and add Price Code No. 48-0200. Motors are chemical service rated continuous duty, TEFC or explosion proof, painted two-part epoxy gray paint. An eight foot (2.4m) three-wire cord and plug are supplied on all TEFC single phase motors. Three phase and explosion-proof motors are supplied without cord or plug.
