Details:
Modulair™ Pump Skids are designed for closed loop cooling of water, ethylene glycol/water, and propylene glycol/water solutions with air cooled fluid coolers for many power generation cooling applications. Pump skids are available in a series of four pre-engineered standard modules with a range of flows from 200 gpm to 2300 gpm. Two 100% full rated pumps and motors are rated for continuous outdoor duty. The bladder type expansion tank prevents air contact with the glycol/water solution. Design pressure is 125 psig at 200 degrees F. at inlet and 150 psig at outlet with 150 lbs. ANSI RF flanges. Piping is fabricated to ASME B31.1. Dual outlet connections simplify connections to two cooler modules. Heavy-duty foot mounted TEFC motors are high efficiency 1.15 SF with Class F insulation. Motors are 1450 RPM for 50 HZ, and 1780 RPM for 60 HZ operation. Motors and switches are factory wired to a weatherproof NEMA 4 electrical enclosure located at the expansion tank end of the skid to provide single point field wiring. Pressure switch on outlet for signal to pump changeover; pressure switch at inlet for low liquid level alarm. The structural steel base and piping is painted primer plus two coats of enamel finish. There is a provision in the base for grounding connections and built-in lifting connections to simplify lifting and installations. Pump features include a heavy duty ANSI standard end suction centrifugal design flanged pump with ductile iron construction; open impeller with external adjustment and balanced to ISO Level G6.3; extra heavy duty shaft to ANSI B73.1M and oil lubricated bearings with a minimum life of two years; industry standard mechanical shaft seal; flexible type spacer shaft coupling; and fully enclosed telescoping OSHA compliant steel coupling guard.
