Advantages of a Hydrostatic Test Pump
One of the most important benefits of a hydrostatic test pump is its ability to handle pressurized water. Most of these pumps use piston or plunger pumps, which work best with pressurized water sources. However, some can be set up to use gravity feed. This works by placing the pump at a lower elevation than the water source and turning it on with its priming valve open. This eliminates the need for a shaft on older machines, which results in fewer moving parts and lower overall weight.
Lighter Than Other Metals
One of the major benefits of aluminum-based hydrostatic test pump components is their lower weight. Aluminum is approximately three times lighter than other metals per cubic foot. That means the smallest pump can carry as much as 2.2 GPM without weighing down your workbench. Aluminum-based pumps also have a lower chance of rusting and freezing, two of the biggest problems that metal pumps face. They can also be lighter if they have brass piping, which is more corrosion-resistant than other metals.
While pure metals are naturally dense, they are not as resistant to corrosion as metals containing other elements. Because of this, alloys are used to increase their strength. One of the most common alloys used in manufacturing is aluminum. It is a lightweight, non-corrosive metal and is especially useful for aerospace components.
Another benefit of an aluminum-based hydrostatic test pump is that it is less expensive. While magnesium alloys are a lighter option, they do not produce the same amount of heat. H13 tool steel dies, on the other hand, are twice as durable as aluminum dies.
More Resistant to Corrosion
Hydrostatic test pumps have several advantages over other test pumps, including ease of use and corrosion resistance. They are typically installed on sturdy frames, have easy-to-use controls, and have a convenient rear-facing hose connection. In addition, they are often built with aluminum alloy housing, which is durable and rust-resistant. Many models also feature a shut-off valve and are designed to be easy to grip.
Hydrostatic test pumps work by pumping water into the piping system at a higher-than-normal pressure. This ensures a drip-free system and minimizes the chance of failure. Following the manufacturer’s instructions when using a hydrostatic pump is important. Before using a hydrostatic pump, fill all lines with water and remove any air. After filling the pipes with water, open the test valve on the pump and let all air out.
There are three main types of hydrostatic test pumps. These include electric, gas-powered, and battery-powered pumps. Choosing the right one is essential as it will determine the duration and amount of work required.
More Reliable Than Electric Plunger Pumps
Hydrostatic test pumps are designed to perform pressure testing on water systems. They use a standard 110/120V power outlet and are UL-certified. They can be primed with a standard garden hose and feature adjustable output pressure. There’s also a built-in bypass that automatically recirculates water after it has reached the desired pressure. Pumps are also equipped with a gauge to display pump pressure. Compared to electric plunger pumps, they are far more reliable and easier to use.
Electric plunger pumps also have a few advantages. They tend to provide a more consistent pressure during tests, which is essential for hydrostatic tests. Additionally, these pumps are compact and can fit into tight spaces. They are also easier to use and store than electric plunger pumps.
Weight is another factor to consider when choosing a hydrostatic test pump. Larger and more powerful machines usually weigh more. Some are even heavy enough to require two people to carry. However, if you only need one, a portable pump will serve your needs just fine.
They Can Be Used With Pressurized Water
A hydrostatic test pump is an excellent tool for pressure testing water systems. Unlike air pressure tests, hydrostatic testing is safer for the system, as the water is pressurized. However, you should always follow the guidelines of your local pressure testing agency. For example, if you want to test PVC or other materials, only pressurize the line within the safe pressure limit.
There are several different types of test pumps for hydrostatic testing, each with advantages and disadvantages. One of the most popular is the trough-style pump. This pump weighs about five to fifteen pounds and is a cost-effective option. However, the trough type has a drawback: it is awkward to carry and can collect dirt. Another option is an electric pump. Electric models weigh about 32 pounds.
When choosing a hydrostatic test pump, the quality of the pump is essential. A high-quality pump should be durable and able to withstand high pressures. It should also be easy to prime and use. Ensure that the pump’s discharge hose is rigid and securely connected.
