Vibration and Cavitation as Related to Reciprocating Pump Valves

Posted by Sam Kelton | July 19, 2019

In a perfect reciprocating pump system, suction and discharge valves should gently open and close as the plunger reaches its full stroke extension into the fluid end or full point of retreat back toward the power end. However, we all know we don’t live in a perfect world and this perfect functionality is never the reality. There is always some lag time in the opening with any model pump valve. The problem is - the more lag, the greater the problem for the pump.

Introducing our WG Sphera Series!

Posted by TPCI | April 10, 2019

In our industry there has been a shift from the somewhat standard pumping system requirements of the 60’s and 70’s to specifications that are more demanding and application specific. Today’s pumping system professionals are forced to find innovative means of increasing system output, albeit marginally, to meet the ever increasing demands of their markets. As performance expectations rise, so does the demand for valves that leverage price with increased performance. There hasn’t been a realistic and cost efficient solution to this problem until now.

Sea Level Basics for Reciprocating Pumps

Posted by Sam Kelton | October 17, 2018

Pump cavitation is a phenomenon that can wreak havoc on even the most durable and robust pumping systems. Blame is often unfairly cast on the construction of the pump itself. However, most times, cavitation is the result of poor system design, lack of maintenance, and improper understanding of the environmental factors that contribute to pump performance, such as sea level and vapor pressure.

The key to preventing pump damage lies in a sound understanding of a parameter called the net positive suction head (NPSH). To avoid cavitation, the pressure at all points of the fluid must remain above the vapor pressure; in other words, the available net positive suction head (NPSHa) must be sufficiently larger than net positive suction required (NPSHr) at the pump inlet.

The NPSHa is determined by the following formula:

NPSHa = Pa +/- Pg +/- Pz – Pvp – Pf – Pac

Where:

Pa = Atmospheric pressure

Pg = Gauge pressure at the supply tank

Pz = Head or lift pressure

Pvp = Vapor pressure of the liquid at its actual temperature

Pf = Pressure required to overcome friction

Pac = Acceleration pressure

Here, we will look at the various factors that affect the NPSHa value and how they influence cavitation.

7 Questions to Check Off When Inspecting for Pump Cavitation

Posted by Sam Kelton | June 6, 2018

Cavitation — the formation of bubbles in a liquid — is the No. 1 problem encountered when operating plunger pumps. Cavitation can cause a remarkable amount of damage to pump components and the pump as a whole, resulting in costly repairs, increased labor needs, and extensive downtime.
