MOTOR SPEED PRODUCT LINE:STAINLESS STEEL — MAG DRIVE PUMPSSectionPageIssueSERIES 89717431743.1DTABLE OF CONTENTSSERIES DESCRIPTIONFeatures & Benefits.2897 Series pumps are designed to provide positivedisplacement pumping capability in those situations thatrequire the highest assurance of liquid containment. Thesemag drive pumps provide for the safe, trouble-free transferof hazardous, EPA-regulated fluids without electronicmonitoring as required with mechanical face-type shaft seals.Hard-to-seal liquids are also easily handled with the VikingMag Drive which eliminates the high cost of mechanicalseal replacement and repair. A variety of coupling sizesare available for flow requirements to 75 GPM. The torquecarrying ability of high-strength magnets allows pumps tobe coupled with gear reducers for slow-speed handlingof viscous liquids. The self-priming positive-displacementpumping principle provides low-shear, non-pulsing flow.Internal gear pumps are available in stainless steel, steel,and cast iron construction.Standard Materials of Construction.2Model Number Key.3Cutaway View & Pump Features.3Specifications.4Dimensions – GG, HJ, HL Sizes (Unmounted).4Dimensions – GG Sizes – MD-A4 & MD-A9 (B Drive).5Dimensions – HJ, HL Sizes – MD-A4 & MD-A9 (B Drive).6Dimensions – HJ, HL Sizes – MD-B15 & MD-B40 (M Drive).6Dimensions – AS, AK, AL Sizes (Unmounted).7Dimensions – AS, AK, AL Sizes – MD-B15 & MD-B40 (B Drive).8Dimensions – AS, AK, AL Sizes – MD-C80 (B Drive).9Dimensions – AS, AK Sizes – MD-B15 & B40 (M Drive).10Dimensions – AL Sizes – MD-B15 & B40 (M Drive).10NPSH Required. 11Selecting the Correct Viking Mag Drive Coupling.12Example 1.12Example 2.12RELATED PRODUCTSStainless Steel, 4197 Series: Catalog Section 1741Cast Iron, 895 Series Mag Drive: Catalog Section 1443GG897MD-B40B, bearing carrier, footed bracket,and mounted pump with flanged ports(shown with optional temperature probe connection)Steel Externals, 893 Series Mag Drive: Catalog Section 1343OPERATING COSITYRANGESERIESGPMm3 hPSIBar F CSSUcSt8977 - 751.6 - 171258.5 60 to 500 50 to 26028 to 25,0001 to 5,500 A Unit of IDEX Corporation Cedar Falls, IA 2020

Along with the canister, this static sealreplaces traditional dynamic seals like packing andmechanical seals. This provides the highest assuranceagainst leakage on difficult to seal liquids.Inner Magnet Assembly. The inner magnet is the driven magnet, aligned by magneticforce passing through the canister. The inner magnet assembly is shielded in a laserwelded 316SS housing to prevent exposure of the magnets to the liquid. A Unit of IDEX Corporation Cedar Falls, IA 2020

NPSHA (Net Positive Suction Head – Available in the system) must be greater than theNPSHR. For a complete explanation of NPSH, see Application Data Sheet AD-19.FOR VISCOSITIES UP TO 750 SSU – See NPSHR table below.NPSHR 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. Add this value to the NPSHR value in the chart below.NPSHR – FEET OF LIQUID (Specific Gravity 1.0), Viscosities up to 750 SSUPUMPSIZEGGHJ, HLAS, AK, AL8402.22.83.97802.63.45.5PUMPS SPEED, 3.5— A Unit of IDEX Corporation Cedar Falls, IA 2020
