High Pressure Pumps

[Quick links:  Jump to content found further down this page]

The most popular high pressure piston pumps are a multi-cylinder, flow-through design. Each cylinder has a spring-energized check valve positioned at its outlet. In operation, the inlet valve seals on the backside of the piston as it drives forward through the displacement cycle. At the same time, the piston pulls the next charge of fluid into the cylinder. As the piston rod reverses direction, the spacer allows the inlet valve to open before the retainer starts to pull the piston back. The piston then moves through the fluid drawn into the cylinder on the displacement stroke. The fluid flows between the piston and inlet valve into the discharge side of the piston, and the cycle repeats.

Diaphragm pumps are another option for high pressure applications. These specialized pumps drive diaphragms with oil pressure to create a uniform balanced load. This allows high pressure operation with long diaphragm life. These pumps are well-suited for tough applications, such as reclaim water, fluids containing abrasives, machine tool cutting fluid, maple syrup, melted chocolate or glue.

Multistage centrifugal pumps have several series-coupled stages. These pumps are used in installations where a high head is needed. Several stages are connected in series and the flow is guided from the outlet of one stage to the inlet of the next. The final head that a multistage pump delivers is equal to the sum of the pressure that each of the stages provide. These pumps provide high head relative to the flow and have a steeper curve that is more advantageous for variable speed drive, also known as variable frequency drive (VFD) applications. They are available in both vertical and horizontal versions.
