FTI Cordless Drum Pump When it comes to drum pumps, Finish Thompson has a wide variety of pumps for any need. But one challenge is there is not a lot of mobility when it comes to drum pumps. In order to operate you will need to have an air or electricity source at your drum. […]
Understanding Torque and Horsepower Understandably so, in the pump industry our focus is primarily on the power delivered BY the pump. How much flow is required and at what pressure? Here at Viking Pump and at our channel partners we have hundreds of experts on this topic. Once we’ve solved for this, we then need to shift […]
MISAPPLICATIONS FOR POSITIVE DISPLACEMENT GEAR PUMPS ACID BASED OR LIGHT WEIGHT HAZARDOUS FLUIDS Pump leakage has become more critical in recent years because of environmental concerns, fugitive emissions, handling of carcinogen materials and loss of valuable products. Acid based fluids typically have viscosities similar to water, and may have no or limited lubricity properties. Internal […]
The Proper Oil Level for Your Compressor Maintaining correct oil level is the most important and easily varying maintenance problem and or question. So many times oil level can cause service issues and the customer is unaware of the issue. Most know that low levels cause-high temperature varnishing and in extreme conditions shut downs […]
Many Different Types of Air Compressors “I want a quote on an air compressor”. This is how the conversation and subsequent negotiation begins. Our first response is “what size?” This refers not only to the CFM required, but also to the pressure required. Once these points are determined, the next question is “what type compressor?” Compressor […]
Compressor Types & Lubrication Methods Compressor types can also be defined by lubrication, i.e. whether lubricated or non-lubricated. Non-lubricated compressors are usually referred to as “oil free”. ISO 8573-1 Class Zero (2010) provides for a purity level that ensures no oil is in contact with the compressed air, and typically indicates no oil is used in […]
Drive method is probably the simplest method of differentiating compressors. The compressor, whether reciprocating or rotary, can be v-belt driven, direct coupled, or either of the above accompanied by a variable frequency drive. The simple v-belt drive is most commonly seen on the air cooled reciprocating compressor, and smaller rotary screw compressors. V-belt drives provide […]
Do I need a suction strainer for my new pump? Many of my customers ask “WHY DO I NEED A SUCTION STRAINER FOR OUR NEW PUMP?” For all new VIKING PUMP positive displacement pump package and CRANE centrifugal pump package proposals we submit – there will be a separate line item for a recommended suction strainer. Please see this […]
Getting The Most Out of Your Viking Abrasive liquid pumps Pumping abrasive liquids are always a difficult application. The hardness and percentage of solids increase the wear in the pump and piping. Pump speed and pressure directly affect pump wear. Pump speed can be addressed by oversizing the pump to reduce the RPM of the […]
Net Positive Suction Head or NPSH Made Easy The pump manufacturer will state the NPSHr, Net Positive Suction Head required, to prevent cavitation or vaporization of the liquid in the pump. The NPSHa, Net Positive Suction Head available, must be greater than that required by the pump. For a basic understanding of Net Positive Suction Head, you […]
