Viking Pump invented the internal gear pump in the early 20th century; but did you know that we carry various other pump technologies? Most of them are easily identifiable based on their shape. But one common mistake that we see is confusing a lobe pump and a circumferential piston pump. So what exactly are the differences and advantages of circumferential piston pump technology (CPP)?
Like any job, you need the proper tools to do it well – and the same is true for repairing or servicing positive displacement gear pumps. Below are helpful hand tools that Viking's pump experts recommend having ready for… read more.
Having a great product, with a great reputation, and being a technology inventor like Viking Pump®, positions you as a market leader with high visibility. As such, other internal gear pump manufacturers naturally want to follow in your footsteps. While that is a huge compliment, it also causes confusion among internal gear pump buyers.
In this article we'll walk through 5 reasons you'll want to stick with genuine Viking Pump parts and products, saving you time, money, and a headache.
Flange standards used on Viking pumps have been in place for over a century so EVERYONE should be experts on this now…right? It turns out not so much. There are various standards and various design differences in each standard. AND the standards have evolved over the years, leading some to use obsolete terms which only compounds the confusion. The following should help clear up some of this confusion as well as give you a resource to help answer questions for others.
Customers don’t ask me to listen to quiet pumps. This is symptom #1 of a cavitating pump. The pump is loud. Descriptors like “growly”, “rumbling”, or “gravelly” are used to describe the atypically loud sound coming from the pump.
“Does it always sound like this?” I ask.
“No, it was fine in the fall, but it’s been loud all winter.”
The Classic+ Series™ features a stainless-steel casing and rotors that are finished to 3A sanitary standards. The modular design can be easily disassembled for both clean-in-place and clean-out-of-place processes. Cusps in the casing's profile maximize efficiency and draining." This series has timed, non-contacting rotors - which minimize shear while providing extended dry run capability.
Unlike most of my colleagues I didn’t start out with a mechanical background. While they were studying kinetics and machine design, I was studying digital electronics and industrial power. When I started my career in the world of pumps, I had to learn a whole new set of concepts. What was surprising was that while the terminology may be a bit different, the concepts are very similar. Think of the following as a “Rosetta Stone” for translating the common terms and concepts of fluid systems to your more familiar terms and concepts of electrical systems.
With today’s fast-paced supply chain demands, it is essential that tanker truck systems can unload contents quickly to ensure timely delivery for optimum manufacturing efficiency. Stony Run Enterprises Inc., a family-owned trucking enterprise located in Hamilton, Ohio, understands this sense of urgency with its commitment to transport multiple types of products with “speed, safety, and professionalism.”
In the world of positive displacement pumping, reduced speed operation is a common requirement. High viscosity liquids, shear sensitive liquids, abrasive liquids, or any combination thereof require the pump speed to be reduced from synchronous motor speeds.
