These mag drive pumps provide for the safe, trouble-free transfer of hazardous, EP-regulated fluids without electronic monitoring as required with mechanical face-type shaft seals. Hard-to-seal liquids are also easily handled with the Viking Mag Drive which eliminates the high cost of mechanical seal replacement and repair. variety of coupling sizes are available for flow requirements to 75 GPM. The torquecarrying ability of high-strength magnets allows pumps to be coupled with gear reducers for slow-speed handling of viscous liquids. The self-priming positive-displacement pumping principle provides low-shear, non-pulsing flow. Internal gear pumps are available in stainless steel, steel, and cast iron construction.

2 Section 1443 Page Issue B SERIES 895 MOTOR SPEED PRODUCT LINE: FETURES & BENEFITS Internal Gear»» With only two moving parts, Viking Mag Drive and Viking s gear-within-a-gear principle provides low-shear pumping. Magnetic Coupling»» Viking Mag Drive magnetically couples the pump to the driver. Magnetic force passing through a stainless steel canister is used to drive the inner coupling, eliminating the need for shaft seals.

Standard material is PPS composite with an optional iron balance plate for high temperature applications. Head Canister Rotor Idler Internal pressure relief valve standard. Returnto-tank valve and plain head optional. Outer Magnet ssembly. The outer magnet is the drive magnet, driven directly by the motor. Inner Magnet ssembly. The inner magnet is the driven magnet, aligned by magnetic force passing through the canister. The inner magnet assembly is shielded in a laser welded 316SS housing to prevent exposure of the magnets to the liquid. Bracket. Designed to mount directly to a c-flange NEM motor (MD- or MD-B coupling sizes) or to a bearing carrier assembly for a shafted version of this pump (not shown). Canister O-Ring. long with the canister, this static seal replaces traditional dynamic seals like packing and mechanical seals. This provides the highest assurance against leakage on difficult to seal liquids.

Performance curves can be electronically generated with the Viking Pump Curve Generator on vikingpump.com. NPSH R data is not available on the Curve Generator. NPSH (Net Positive Suction Head): The NPSH R (Net Positive Suction Head Required by the pump) is given in the table below and applies for viscosities through 750 SSU. NPSH (Net Positive Suction Head vailable in the system) must be greater than the NPSH R. For a complete explanation of NPSH, see pplication Data Sheet D-19. FOR VISCOSITIES UP TO 750 SSU See NPSH R table below. NPSH R for high viscosities can be estimated using the following method: 1. Calculate line loss for a 1 foot long pipe of a diameter matching the pump inlet port size. Use your flow rate and max viscosity. 2. Convert this value into Feet of Liquid (S.G. 1.0) 3. dd this value to the NPSH R value in the chart below.
