Frequently Asked Questions

Viking Pump operates a foundry, a 250,000+ sq. ft. machining, assembly and testing center, and an extensive product engineering and testing lab in its world headquarters in Cedar Falls, Iowa, USA. This level of vertical integration ensures maximum quality, ability to satisfy special needs, and to meet project schedules.

Industrial pumps are pumps used in more general applications like all varieties of refined fuels & lubricants, resins & polymers, alcohols & solvents, asphalt & bitumen, polyurethane foam, food products, paints & inks, soaps & surfactants, and heat transfer fluids.

Viking Pump's positive displacement pumps displace liquid with each revolution of the internal pumping elements. This is done by trapping liquid between the pumping elements and a stationary casing. Depending on the application, a pump may need to be jacketed or electrically heated in order to keep a warm ambient temperature inside the pump to prevent the product from solidifying.

The price of a Viking industrial pump can span from as low as $500 to as high as $250,000. The price is largely dependent on the size and application in which it is being used. This is why our Viking experts work directly with you to evaluate your specific need so that we can recommend the pump that will give you the best return on your investment.

Viking industrial products are sold through our reliable distribution channel around the world. These distributors are trained in our product and can help install and service your pump. Find your area distributor by visiting https://www.vikingpump.com/contact.

Specifications can be found on the pump pages after clicking on the pump of interest. Additional specifications can be find in our related literature and catalog sections, also available on the pump pages.

We offer adjustable clearances as a standard that enables handling viscosities from 28 to 2,000,000 SSU (1 to 440,00 cSt). Our internal gear products also have low shear to protect your liquids and a smooth, non-pulsating flow for accurate measurement or metering.

Many of our models come with our patented O-Pro® Seal which dramatically reduces leaks. O-Pro® Seals utilize a series of O-rings to create a robust seal and lubrication chamber, all in one. O-Pro® Barrier seal functions as both a seal and bracket bushing; O-Pro® Cartridge & Guard seals are simple retrofit options. This means a safe, clean environment for your staff and money saved from lost product.

A hygienic pump is used in systems where cleanliness is vital to the product being pumped, such as food products, beverages, and pharmaceuticals. Hygienic pumps need to be able to be cleaned and sanitized on a regular basis and must be able to handle liquids gently. Indications that a pump is considered hygienic include certification of being an ATEX pump as well as other certifications.

The Viking hygienic pump with the highest pressure rating is our TRA®20 Series at 500 PSI. We encourage potential customers to contact their local distributor to discuss your specific application needs.

Viking's hygienic positive displacement pump products are manufactured both in Cedar Falls, Iowa, USA and Eastbourne, UK.

Circumferential piston pumps handle high value shear sensitive liquids across hygienic applications where gentle handling, cleanability, and efficiency are paramount. Viking Pump Hygienic has a wide range of displacements with high pressure capabilities. It's ability to handle solids is excellent and has low shear characteristics across a wide range of product viscosities. 

Rotary lobe pumps are the mainstay of many hygienic fluid handling applications where gentle handling & cleanability are of utmost importance. These pumps have a wide range of displacements, good solids handling capabilities, and low shear characteristics across a wide range of product viscosities. The non-contacting pumping principle for RLPs means no metal-on-metal contact, limiting pump wear regardless of product viscosity. 

Centrifugal pumps can transfer large volumes of liquid, but efficiency and flow decrease rapidly as pressure and/or viscosity increases. Rotary pumps and circumferential piston pumps, on the other hand, offer higher efficiency wherein they move a consistent amount of liquid at a constant speed. They are gentle on liquids and have extremely low shear characteristics across a wide range of product viscosities.

Peristaltic pumps certainly have their place in the hygienic process, especially when handling fluids that will be infused with someone's blood (like IV fluid, for example). However, there are phases of the hygienic process that require gentle handling of the fluid being conveyed and the pulsation of a peristaltic pump could damage the product. That is why having a RL or CPP with consistent speed and flow is ideal, depending on the phase of production of the liquid.
