Description
Vertical medium-voltage motors with a P-base flange and increased permissible thrust load (High Thrust) are designed to drive vertical turbine and submersible pumps at water supply and wastewater pumping stations, in irrigation, in the oil and gas industry and at industrial plants. They are available with a hollow shaft (VHS, a vertical hollow shaft through which the pump shaft passes) and with a solid shaft (VSS), in WPI protected design and in totally enclosed fan-cooled (TEFC) design. Parameters according to the product descriptions: WPI design 200–1000 hp at 1800 and 1200 rpm (for the solid shaft also 900 rpm); TEFC design 200–700 hp at 1800 and 1200 rpm; voltage 2300/4000 V, frequency 60 Hz, service factor 1.15 when supplied with sinusoidal voltage. Standard equipment includes a ball anti-reverse ratchet that prevents reverse rotation of the pump (non-sparking in TEFC), a drip cover and 120 V anti-condensation heaters; in hollow-shaft designs, a keyed coupling. TEFC motors allow reduced-voltage starting and are CSA certified for Class I, Division 2, Groups B, C, D with temperature class T3. The motors are part of the stock programme; for higher powers the company manufactures custom vertical motors up to 25,000 hp.
