Viking Pump Rotary Gear Solutions

Viking pumps are defined as positive displacement pumps that displace a fixed quantity of liquid with each revolution of the pump by moving liquid between the pump elements and a stationary casing. Since 1911, Viking Pump has been the leading innovator and solutions provider for positive displacement pump applications around the world.

Internal Gear Pumps: The internal gear pumping principle was invented by Jens Nielsen, one of the founders of Viking Pump. It uses two rotating gears which un-mesh at the suction side of the pump to create a vacuum which pulls fluid into the pump. 

External Gear Pumps The external gear pumping principle uses two rotating gears which unmesh at the suction side of the pump to create a vacuum which pulls fluid into the pump.

Rotary Vane Pumps:  Vane pumps are used for liquid transfer applications from chemicals to liquefied gases. Vanes extend from slots in the rotor, sweeping liquid through a cam-shaped cavity. The vanes provide very low slip and high volumetric efficiency.

Viking Pumps Accessories: Accessories can be installed on your complete pump unit by Viking Pump or your distributor, or purchased separately.

Centrifugal Pump

Centrifugal Pump

Centrifugal Pumps use rotation to impart velocity to a liquid, then converts that velocity into flow.

A centrifugal pump is a machine made up of two primary components: an impeller and a casing. The pump uses rotation to impart velocity to a liquid, it then converts that velocity into flow. The energy from the rotation is being imparted to a liquid in the form of velocity. Once in a liquid form, the energy is converted into a steady flow.

Plastic Non-Metallic Pumps

Plastic Thumb

Engineered Plastic Non-Metallic Pump Distributor

Custom engineered plastic non-metallic pumps by MARCH Manufacturing and Vanton 

Centennial Equipment is the premier distributor and certified repair center for plastic non-metallic pumps, parts and accessories by March Pumps, Vanton and Yamada in Colorado, Wyoming, North Dakota, South Dakota & New Mexico.  

March Pumps: Centrifugal Sealless Magnetic Drive Pumps can be used in a variety of applications and system. Magnetic Drive refers to the coupling between the wet end of the pump and the motor. In "direct drive" pumps, the impeller of the pump is attached to the shaft of the motor, and this design depends on the shaft seal to contain the chemical. In a magnetic drive pump, the wet end and motor are two separate contained parts, connected by only a motor bracket. At the end of the motor shaft, a drive magnet is attached, and as the drive magnet rotates around the rear housing, the impeller, which is fixed upon another magnet, spins in synchronization. Learn more

Vanton:The wet end components of every Vanton pump are made 
from corrosion and abrasion resistant engineered plastics 
such as, polypropylene (PP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), and polyvinylidene fluoride (PVDF). Completely inert, these thermoplastics are impervious to acids, caustics, salts, solvents, chlorides, halogens, and other aggressive, abrasive chemicals that can attack pumps made of metals, plastic or rubber lined metals, and fiberglass reinforced plastics. Learn more. 

Yamada - Beau, need information on the Yamada Non-metallic pump. Link to proper page. 

The products we carry are engineered for handling corrosive, abrasive, caustic and ultra pure liquids. Our engineers work with you to find the right plastic non-metallic pump to work in your situation - alternative energy, chemical pumps, environmental remediation, industrial application, mining applications,  petroleum oil and gas, and more.
