Viking Pump's Universal Seal, cast iron products have been the positive displacement pump standard for decades…and this latest evolution has raised the bar. Customization and flexibility are at the core of these products. The new U-Plus Bracket™ accepts even more seal types including packing, various stuffing box component seals, cartridge seals, behind the rotor seals, and Viking Pump's own O-Pro® seals. You can also upgrade these pump series to include the ProPort™ casing—an option that includes a number of possibilities...

To begin, securely clamp the pump to the bench or work surface to keep the pump from tipping. Next, remove the head cap screws. Remove the head. Tip the head back to keep the idler pin from falling off the idler pin. Remove the idler. Discard the head gaskets. Note the number and thickness of the gaskets as these will need to be replaced. Loosen and remove the bearing plate cap screws and remove the bearing plate. Next, insert a brass or hardwood bar into the port opening to keep the pump from turning. Using a bearing locknut tool or spanner wrench, loosen and remove the locknut.

Solids like chocolate, wax, and asphalt need to be melted prior to being pumped. Jacketing is a common way of heating the pump to successfully transfer these room temperature solids. Pump jacketing consists of chambers that surround the pumping cavity. Heating mediums such as hot oil, water, or steam are pumped into these chambers which then heat the pumping cavity as well as the liquid inside. Once the liquid is melted, the pump can be started. Common pump components that can be jacketed include brackets, heads, rotor bearing sleeves, casings, and relief valves.

Are you tired of throwing away pumps on your tank truck? This is the RTPg Series™ from Viking Pump — the pump built to keep your tanker truck moving and your bottom line protected. Designed specifically for tanker trucks, the RTPg Series™ is a cost-effective cast iron alternative when stainless steel isn’t required — but performance still is. With Viking Pump's internal gear design, these pumps deliver quiet, smooth operation and bidirectional flow. Unlike throwaway pumps, the RTPg Series™ is fully rebuildable - requiring no special tools.

Hello, I'm Kyle Benning, OEM sales manager at Viking Pump. Data centers across the globe rely on fuel transfer pumps to maintain operation. I want to highlight some of our pump technologies that are ideal for this critical process. Data centers are essential for storing and processing information in our rapidly growing technological world. Small data centers may consume 10 to 50kW of power, while larger facilities can exceed 100MW. In the U.S. alone, roughly 3% of our power consumption goes to powering these facilities.

This is a gear pump, a type of rotary positive displacement pump. Its tight-fitting clearances allow it to evacuate air in the suction line to prime the pump. And once primed, it's capable of pulling even higher vacuums. This ability to self-prime is key in applications like unloading drums, totes, rail cars, and barges. But as good as this pump is at pulling the liquid in, it's always going to be limited and not based on the pump. It's based on an invisible force pushing the liquid in from the outside, and that's atmospheric pressure.

Viking Pump is the global leader in positive displacement pumping solutions and we proudly manufacture and assemble our products in Cedar Falls, Iowa. With our own dedicated foundry and machine shop, we build our products from start to finish to our own high standards. This vertical integration gives us better control of our supply lines, enhances our ability to respond to change, and creates stability for our partners and customers. We’ve been centrally located in Iowa since 1911. We're proud of that history. We're proud of the work we've done, still do, and will do together.

Hi! I’m Chad Wunderlich with Viking Pump and this is an internal gear pump. With each rotation of the gears, a set volume of liquid is moved from the inlet to the outlet. And if I were to reverse the direction of rotation, I reverse the direction of flow. Now this isn’t unique to internal gear pumps, other rotary pumps like external gear, lobe, and hose pumps exhibit this same behavior. But did you know it’s possible to make this internal gear pump deliver flow in just one direction, independent of the direction of rotation?
