Welcome! In this video we will guide you through the disassembly and reassembly of Viking Pump’s 893, 895, and 897 Series™ mag drive internal gear pumps.
This video applies to these pump models: GG893, HJ893, HL893, AS893, AK893, AL893, GG895, HJ895, HL895, AS895, AK895, AL895, GG897, HJ897, HL897, AS897, AK897, AL897
Welcome to the Viking Pump foundry in Cedar Falls, Iowa, where we’ve been at the forefront of manufacturing gear pumps for decades. Our foundry is a cornerstone of our vertical integration capabilities, allowing us to produce castings and parts at speed.
Viking Pump invented, patented and manufactured the very first sealless mag drive rotary positive displacement (PD) pumps in the world, and developed several series over time for different applications, including the first generation 825, 895 and 855 ™ internal gear pumps.
Of these first generation mag drive pumps, all had different footprints from their dynamically-sealed cousins with...
Packing is one of the most common and simplest seals for positive displacement pumps. Packing consists of braided or formed rings that are compressed inside the stuffing box of a pump. As the packing gland is tightened, the packing is compressed against the shaft and the inside of the stuffing box bore - creating a seal. When the pump is operating, process liquid cools and lubricates the packing. The pump must leak or "weep" slightly to ensure proper lubrication. Packing is one of the oldest forms of shaft sealing. Original packing was made of materials such as leather or rope.
The terms bitumen and asphalt are often used interchangeably, but they are two completely different materials, causing confusion inside and outside the industry. Throw in regional differences in meaning and language, and it’s time to set the record straight, along with tips on bitumen pump selection.
An Engineering firm recently purchased three large internal gear pumps through a local distributor in northern Illinois. In this case, the pumps were intended to be a prime mover for loading their customer’s product—vacuum gas oil (VGO)—onto a transport barge. Traditional pumping technology, i.e., centrifugal pumps, was not a viable option, as pump performance tends to vary based on product viscosity changes. Since pump operations were scheduled for during the middle of winter, VGO viscosity was sure to increase with dropping temperatures, making it harder to pump.
If you’ve ever fallen asleep reading pump texts about NPSH, you’re not alone. But here’s an easy-to-understand, graphical approach to ensuring your calculations.
Welcome. In this Quick Tip video, we will show you how to switch between flat gaskets or o-rings in Viking pumps with the ProPort™ casing. The bracket, head, and ports will each have a flat gasket or o-ring for sealing. Depending on application requirements, users can switch between these elastomers as needed. Before you begin please consult the appropriate technical service manual for safety information. A copy of the latest revision can be found at vikingpump.com.
Viking Pump’s original applications started at home, right here in Iowa. This original list included asphalt, fuel oil, turpentine, linseed oil, and water but did not include one of Viking Pump’s most common applications in the state today: corn syrup. Corn syrup is a sweetener made from, you guessed it…corn, and used in a variety of foods, candies, beverages, and pet foods. Next, is Rhode Island. Bunker C has many names: Heavy Fuel Oil, Bunker Oil, #6 Fuel Oil.
Welcome, in this video quick tip video we will guide you through the installation of Viking Pump’s O-Pro® Cartridge seal into a pump with the U-Plus™ bracket. Before installing the new seal, ensure the shaft is free of any debris or wear any burrs can damage o-rings upon installation. First, prepare the O-Pro® Cartridge seal for installation. Lubricate and install the two internal o-rings into the O-Pro® cartridge seal gland. Apply gasket sealant to the O-Pro® Cartridge and place a gasket. Give the gasket a quarter turn and then flip, to ensure both sides have a continuous bead of sealant.
