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.

In the world of gear pumps, it is common to have liquid handling applications where pressure and vacuum are of concern. So, we wanted to share our perspective and recommendations, to help with making pump choices and decisions for the various pressure and/or vacuum scenarios you may encounter.

Industrial gear pumps have many uses in a wide array of market applications—ranging from food processing to pouring asphalt. A growing area in need of specialized gear pumps is in the oil and gas industry, particularly with regards to the removal of water from natural gas via dehydration. Viking Pump entered this market to support customers striving to deliver high-quality product 24/7 to their end users in the face of rising global natural gas consumption. This increasing demand is expected to continue through 2040, due to population growth, coal displacement by cleaner energy, fracking, etc.

Asphalt, also known as bitumen, is a sticky, black, and highly viscous liquid, or semi-solid form of petroleum. Asphalt is man's earliest organic engineering material. Its application as an adhesive and waterproof material dates to the dawn of civilization. The asphalt market thrives today largely for road building, roofing, and various types of repair work where its water-proofing qualities are required, as well as in rubber and adhesive compounds.
