897 Series Stainless Steel Internal Gear Pumps Information

Product Type
Gear, Positive Displacement, Magnetic Driven, Sealless
Features & Benefits
• Sealless mag drive eliminates the shaft seal to provide the highest level of liquid and vapor containment • All liquid and vapor is hermetically sealed in the pump • Used especially for hazardous and difficult-to-seal liquids • Optional high pressure canister for inlet pressures up to 2,250 PSI (155 BAR) • Balance plate standard material is PPS composite, with an optional iron balance plate for high temperature applications • Bracket designed to mount directly to a c-flange NEMA motor (MD-A or MD-B coupling sizes) or to a bearing carrier assembly for a shafted version of this pump (not shown) • Canister O-ring - along 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 • 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 • The outer magnet is the drive magnet, driven directly by the motor
General Description
Viking Pump 897 Series™ internal gear pump is the perfect solution for refined fuels, lube oils, rotating equipment lubrication, and more due to the sealless mag drive which provides the highest level of liquid and vapor containment. It can handle flows up to 75 GPM (17 m³/h).
