Do Spherical Valves Trump All?

Posted by Sam Kelton | June 13, 2019

Spherical valves are just one of the many valves working in high-pressure applications today in reciprocating pumps. It is a common belief that a valve is a valve and that they are equal regardless of type. While this is true in the sense that all valves allow or inhibit the flow of fluids, there are minute differences that make one valve preferable over another in any application. Let’s take a brief look at the most common types of valves used in reciprocating pumps with some of the advantages and disadvantages of each.

Preventing Suction System Problems in Reciprocating Pumps

Posted by Sam Kelton | March 13, 2019

Reciprocating plunger pumps are a type of positive displacement pump that drives liquid at high pressures in a variety of industrial applications. They operate by creating changes in pressure using a moving component known as a plunger which, on its outward motion, draws fluid into the chamber through the suction valve; then on its inward motion, opens up the discharge valve and pushes the fluid out a delivery pipe at a rapid velocity. Working with the plungers are the pump valves, plunger packing and stuffing box components to ensure optimal performance.

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 = Gead 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.
