8124A Series Universal Product Line Cast Iron Internal Gear Pumps
The 8124A Series is the ideal sealing technology within Viking’s Universal Product Line pumps. It is dimensionally interchangeable with other Universal Product Line pumps, allowing an easy upgrade from packed or mechanical seals to sealless technology.
Viking Pump 8124A Series’ canister is hermetically sealed, providing the highest level of liquid containment available by eliminating traditional dynamic shaft seals traditionally associated with hazardous, hard-to-seal, or expensive liquids. It also eliminates housekeeping issues and downtime due to seal failure. This product is designed to handle a broad range of applications (such as caustics, isocyanates, adhesives, solvents and mercaptans) requiring continuous duty at pressures up to 200 PSI (14 Bar).
This Series features 9 different sizes with flows to 500 GPM (114 m3/h) They may be applied to both thin and thick liquids, and operate in either direction. They are also capable of operating under suction lift conditions. The 8124A seriescontinues the tradition of most robust line of internal gearpumps built by Viking Pump.
Viking Pump 812A Series Features & Benefits
• Positive displacement, internal gear pumping principle.
• Gear and pump geometry has been optimized based on more than 100 years of experience. These pumps are designed to provide exceptional reliability and freedom from down time and maintenance.
• Drop in foot print allows direct replacement of a Viking Universal Product Line pump without re-piping.
• Foot-mounted design.
• Available with 90° ports, which can be rotated in 90° degree increments, or with 180° ports (Check individual sizes).
• Ports are threaded or flanged.
• Pumps come with an adjustable internal pressure relief valve on standard design.
• The pump operates in either direction, allowing one pump to be used for both loading and unloading. There is a slight reduction in capacity at viscosities less than 100 SSU with counter-clockwise rotation.
• Adjustable end clearance for fluid viscosity or temperature by use of head shims.
• Static O-rings at key points assures liquid containment.
• Pumps conforming to ATEX hazard prevention requirements are available
• Short-term Run-dry Capability. Unlike many mag drive pumps, the 8124A series may be run dry for short periods, such as for clear lines when unloading, or in the case of accidental empty tank situations.
