• March “Orbital” Magnetic Drive Pumps eliminate the conventional shaft seals found in most pumps. This means that there is no rotating seal to wear and allow the liquid being pumped to leak out. In addition to this unique “sealless” design, the pump is hermetically encapsulated in epoxy. This epoxy encapsulation now allows the pumps to be run fully submerged in many liquids. The models 1U-MD, 1A-MD, and 1C-MD pumps can be run totally submerged or can be run in open air for complete moisture protection.
• All models are standard in 115 Volt, 60 cycle, 1 phase A.C. All cord sets are U.L. LISTED 18/3 wire SJT plastic cords with ground type molded plugs. Standard cord length is 6 feet. The motors are C.S.A. approved under File NO. 40072. The pumps are U.L. Recognized for pumping water under the U.L. component program.
• All Screws are type 18-8 stainless steel. All “O” Ring Gaskets are Buna N Rubber. The Stationary Spindle is type 316 stainless steel. Motor Bracket is Glass Filled Noryl. Pump Housing & Cover is Cycolac or Polypropylene. Impeller Assembly is Nylon and Ceramic. Thrust Washer is Teflon.
• Small but versatile, March Series 1 pumps can deliver a minimum of 1.7 GPM (7 LPM) up to 3.0 GPM (9 LPM). All Series 1 pumps are capable of serving applications with a maximum head of 4.5 ft. (1.3 m). at zero GPM (0 LPM). Applications include photographic processing equipment, refrigeration systems and water displays or fountains. Maximum recommended fluid temperatures are 190º F (87º C) for open-air models, or 130º F (55º C) for submersible models.
