Features Common to All Viking Pumps

• Constant capacity regardless of pressure.  Viking positive displacement pumps provides relatively constant
output regardless of changes in pressure, making them well suited for metering applications.
• Flow proportional to speed.  The pump's output is directly proportional to its speed, allowing it to be used for
metering applications using a variable speed drive following a process control signal.
• Direction of flow is reversible.  The same Viking pump may be used for loading and unloading of tanks when used
with a driver capable of reversing direction. (Exceptions are Viking Spur Gear and Mag Drive models).  Note that
pressure relief must be provided in both directions of operation.  
• Smooth, near-laminar flow. Unlike reciprocating PD pumps (including diaphragm, piston, plunger and rotating
piston principles), Viking rotary pumps offer smooth, non-pulsating flow which reduces friction loss and cavitation due
to acceleration and deceleration losses, reduces water hammer, and aids in mixing two streams by eliminating
slugs of fluid.
• Self-priming, with suction lift capabilities.  Viking pumps are capable of self priming when wetted, and are capable
of pulling a suction lift where positive suction head is not available.
