Waterjet cutting is widely known for its ability to cut virtually any material to near net shape. These materials vary from rubber to plastics, composites to metals. Versatility is a benefit waterjet cutting brings to many businesses, including New Hampshire based company, Plan Tech. Plan Tech has been manufacturing urethane parts for over 30 years, providing products for diverse groups of industries. Urethane is a high-performance rubber that can be molded easily, shaped accurately, and offers many different finishing options. We’ve invited guest blogger Kevin Healy, Vice President of engineering at Plan Tech, to tell you more about how waterjet cutting has impacted their productivity. With their vast experience and in-house capabilities, they consistently deliver tight tolerance custom urethane parts.

Guest Post: 5 Key Waterjet Terms We Should All Understand
I’m pleased to say that we have a guest blogger today. Colleen Carnagey is a major part of Flow’s marketing group and she would like to introduce to you a new feature on our website that might be of real value to you as you become more educated on waterjet capabilities.
Over the years waterjet has created its own vocabulary. I’m fairly new to Flow (in Flow terms–4 years isn’t much on 20), and one thing I realized almost immediately is to feel confident in your understanding of waterjet technology as a whole, you must feel confident in your understanding of the terms used to explain it.
Should I Leave My Pump Running?
Some recent emails from readers have come in asking whether or not they should leave their pump running in a ‘dead head’ state. Or put another way: what is a reasonable amount of time that a pump should be left under pressure when it is not being used to process material?
The Basics of a Waterjet Pump
There are two types of pumps used today in waterjet cutting: the linear intensifier pump and the rotary direct drive pump.
Today, both intensifier and direct drive pumps are capable of reliably delivering ultrahigh-pressure water, and both are successfully used in industry. The two pumps have certain components in common. They both have a motor, water filters, control system, and sensors, among other similarities.
Before we start looking at these two pumps separately, let’s take a look at how the industry defines differences in pressure levels. Please note that pressure ranges follow typical high pressure plumbing runs (water delivery lines, T’s, elbows, etc.).
