Viking Mag Drive 855 Series Internal Gear Pumps

The Viking Mag Drive 855 series internal gear pumps offer exceptional reliability through their robust, sealless design, which eliminates seal leakage. The pump’s driver turns an outer magnet, whose force passes through a stationary O-ring-sealed canister to turn an inner magnet, which drives the pump shaft without the need for seals. The pumps feature adjustable end clearance to maximize efficiency, and ANSI- or DIN-flanged ports for sealing reliability. They may be close-coupled to NEMA C or IEC B5-flange motors, or long-coupled. Long field life and reduced downtime are also ensured by a thrustcontrolled design that allows short-term run-dry capabilities. This greatly reduces the possibility of damage from priming and accidental empty tank situations. This series of pumps offers flowrates of up to 135 gal/min with pressures up to 200 psi at temperatures ranging from –60°F to 500°F.
