The motors covered by DOE regulations include a variety of motors including single-speed, continuous-duty polyphase motors with voltages not greater than 600 volts; motors with or without mounting feet; motors built in a T- or U-frame; motors built with synchronous speeds of 3600,1800,1200or 900 rpm (two, four, six or eight poles, respectively); National Electrical Manufacturers Association (NEMA) Design A and B motors from 1 to 500 hp, NEMA Design C motors from 1 to 200 hp; and motors that are close-coupled pump
or vertical solid-shaft normal thrust motors.
Baldor also stocks Super-E severe duty motors up to 700 hp in low and medium voltages, C-Face to 100 hp, explosion-proof through 200 hp, and close-coupled pump
ratings up to 50 hp.
Models include general-purpose, chemical processing, C-face, explosion proof, and close-coupled pump
motors with 1 to 1,500 horsepower ratings.
The introduction of the CombiMagBloc close-coupled pump
extends the established Combi range of safe and environmentally friendly, seal-less pumps.
Tru-Fit is a new close-coupled pump
drive designed to resolve space and coupling alignment issues and increase process productivity.
The line also includes chemical processing motors up to 400 hp, C-face to 25 hp, explosion-proof through 60 hp, and close-coupled pump
ratings up to 50 hp.
While this discussion has centered on the basic close-coupled pump
with electric motor drive, the sanitary pumps are rapidly expanding in design and application.
The direct-coupled design of Bredel heavy-duty hose pumps combines the small footprint of close-coupled pumps
with the reliability and simplicity of long-coupled pumps.
Nemo also supplies a complete series of close-coupled pumps
ideal for a wide variety of applications where cost effectiveness is important.
Also on show will be their range of Duplex and Trio close-coupled pumps
These compact, close-coupled pumps
are designed for handling flow rates up to 140 mc/hr, at heads up to 44 metres and maximum system pressures of 6 bar.
Watson-Marlow 620 series close-coupled pumps
are pumping inorganic polymer coagulants such as ferric sulphate, which perform well with thick flocs and offers fast sedimentation.
