Today’s post will focus on what NPSHA is and how it applies to your sanitary pumping application. To begin, NPSHA stands for Net Positive Suction Head Available. NPSHA should not be confused for NPSHR, which stands for Net Positive Suction Head Required.

This post will be the first in a series of posts focusing on applications and common questions we’ve helped our craft beer customers with.

Failure of the mechanical shaft seal is the most common cause of pump downtime. The shaft seal is exposed to a wide variety of conditions and it can be quite difficult to identify why a seal failed. This post will take a look at the most common costs of seal failure and readdress how we reduce the frequency of seal failure.

Outside of efficiency, the low slip design of the Waukesha Universal series pump allows us to accomplish four useful things- it allows us to pump low viscosity fluids in low NIPA systems, it allows us to pump from vacuum vessels, self-prime, and meter fluids. This post will look at each of these four benefits and why they are important to system performance.

One of the most common errors made when sizing an ECP pump, such as the Waukesha Universal 1 or Universal 2 series pump, is failing to take into consideration the range of product viscosities the pump will handle. This post will focus on that issue and what steps we can take to ensure adequate drive speed range is selected to handle a variety of products. To begin, a sanitary process system may require that the same pump handle both viscous and thin products. A simple example c

Now that we know what BHP, VHP, and WHP are, we can better understand the efficiency of a pump as well as the total power requirements. The efficiency of a pump is the ratio of the WHP to the BHP or total horsepower consumed.

One distinguishing factor are the 17-4 PH shafts. 17-4 PH steel has been chosen by Waukesha, and copied by others, because of the extended service it offers under extreme conditions.

Hopefully this posts sheds some light on the difference between flow rate and flow velocity. While flow rate and flow velocity are related, they are not the same, and both need to be taken into account when sizing a pump.

In previous posts we have gone over different aspects of sanitary metering and dosing systems including defining the criteria for […]

Shear is defined as relative motion between adjacent layers of a moving fluid. When one layer of a fluid moves adjacently to another layer of fluid, it can begin to exhibit the deleterious effects of shear. Shear rate is defined as the measure of the extent or rate of relative motion between adjacent layers of a moving fluid. Therefore:

One of the most important factors in sizing a pump is figuring out your total head requirements. Head is not quite the same thing as a pressure. The differences are nuanced and this post will aim to explain.
