How Pump Packing Works - Animation

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.

Viking Pumps load vacuum gas oil onto barge in cold water environment

Search Description

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.

Chocolate Plant Eliminates Leakage with O-Pro® Barrier

Search Description

A major producer of chocolate confections in the eastern United States had been operating many Viking pumps on a variety of confectionary liquids for decades.

Many of these gear pumps have shaft packing, an extremely reliable means of preventing leaks, but which require some level of “controlled leakage” to cool and lubricate the packing. In a time of stricter FDA standards, food processors are now seeking new solutions to eliminate leakage, as it can create a slip and fall hazard and, furthermore, waste valuable product.

50 States / 50 Pumping Applications: Iowa, Rhode Island, California, West Virginia, Colorado

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.

Quick Tip: How to install an O-Pro® Cartridge seal into a Viking pump

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.

Copper Mining Operation Optimizes Sulfuric Acid Handling

Search Description

Copper is fast becoming a critical resource as the world shifts to an increasingly lower carbon footprint, and with the growing demand comes a need for more efficient processing (i.e., refining) of the mineral ore.

 

The owner of a copper mine in Antofagasta City, Chile wanted to replace its legacy centrifugal pumps used for injecting sulfuric acid into agglomeration tanks – where crushed copper is heaped into uniform particles and sprayed with sulfuric acid + water. The acid component helps to optimize ultimate metal recovery by improving permeability of the raw material at this stage in reparation for the next step: lixiviation, or leaching, to extract the metal.
