Industrial applications that require high-pressure system components often rely on plunger pumps for successful operation. These pumps see frequent use in process technology and cleaning applications.Read More >>
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.Read More >>

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
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.Read More >>
Triangle Pump Components, Inc. (TPCI) recently trademarked three product names for our reciprocating pump valves and components. These valves and extension rods, all of which meet ASTM and ISO 9001-2015 standards, feature names derived from various origins with significant meanings related to their features and applications.
Below is a closer look at the meanings behind three of our newly trademarked products.
Offering great versatility, mechanical seals are commonly employed to seal pumping equipment. However, there are still a number of pumps and devices that make use of compression packing for sealing purposes. Such pumps are used across a wide range of industries, including pulp and paper manufacturing, power generation, and water treatment, and play a critical role in supporting various industrial processes.Read More >>
To put it simply, pumps work based on the principle of pressure difference: Fluids flow from regions of higher pressure to regions of lower pressure, and pumps facilitate fluid transfer by creating a pressure difference, or pressure head.Read More >>
Comprised of a disc and a seat, plate valves are an essential component in many types of pumping operations. The disc moves between the seat and retainer in relation to the variations in fluid pressure on its sides, thereby controlling the pressure flow. Other plate valve components include the bolt, the springs, and the plate.Read More >>
