What You Need to Know About Hydrostatic Testing Pumps

What You Need to Know About Hydrostatic Testing PumpsYou might be wondering what hydrostatic testing is and how it can help you. Hydrostatic testing involves pumping water into a closed pipeline to find leaks. Using a pump, you can easily test the efficiency of a pipeline and avoid any costly repairs later. Read this article for more information. Here, you’ll learn more about the types of hydrostatic testing pumps available today.

Problems With Quick-Disconnect Couplings

When hydrostatically testing a pump, it is important to know how to handle quick-disconnect couplings. This type of coupling has a one-way valve that allows the hose to be disconnected without pump assistance. This is an especially critical step for fire sprinkler system inspectors, as they must check the system’s pressure without assistance from the pump.

In many cases, the hydraulic pump is the first component to be replaced when an issue arises. However, this is often the most costly and time-consuming part to replace. Always conduct several tests before making a change. If the pump has recently failed, perform the most straightforward tests first. A few other tests may be necessary. For example, if the oil level in the pump is low, the shaft seal could be prematurely worn.


Hydrostatic testing pumps can be used to verify the safety of water pipes and pressure systems. They detect small leaks and are suitable for testing newly installed and repaired pipes. These pumps are dependable and durable. You can choose the model that best suits your needs. There are two types of hydrostatic testing pumps. Lightweight hydrostatic testing pumps are portable and easy to use. The EL-series model is suitable for indoor and outdoor use. The EL-series pumps feature a 1 HP electric motor and liquid-filled gauge and are lightweight. They are easy to operate and can be used for various applications, including sprinkler systems, irrigation lines, plant piping, and more.

The HP-Series is a pneumatic hydrostatic test pump that provides pressure ranges of 30,000 PSI and flows rates up to seven GPM. For use, 100 PSI of standard shop air is required. In addition, this lightweight model can start and stop while under pressure. Portable hydrostatic testing pumps are compact, lightweight, and designed to be used in remote locations or confined spaces. They weigh less than 40 pounds and have multiple portability options.


Hydrostatic testing pumps are ideal for a variety of applications. Whether testing a small water line or a pressure system, these pumps have an EL-series low-volume design and simple operation. Their dual check valve system eliminates waste bleed back during the test, which is especially beneficial when operator fatigue is an issue. Moreover, these pumps are suitable for various fluids, including oils, fuels, chemicals, and gases.

The Black Diamond Hydrostatic Tester from GD Energy Products offers peace of mind and ease of maintenance when testing pressure equipment. This pump is among the most affordable options available in the market and can perform the testing process in less than 60 seconds. This model also requires only one operator to complete the hydrostatic evaluation. The compact hydrostatic tester also offers greater accuracy and requires only one person to operate. And its lightweight design also saves on space.

Pressure Regulators

Pressure regulators are a necessary part of any hydrostatic testing pump. This is because the pump will be under pressure for different tests on different days. For example, one day, a company might test-fire sprinklers and hoses. For this, the pump could be rated at 1,200 PSI. On another day, the operator could turn it down to 250 PSI. Using a pressure regulator, the pump’s pressure would be adjusted to the desired threshold, and any additional pressure would be bypassed.

EL-series of hydrostatic testing pumps: These pump models are low-volume medium-pressure systems that are ideal for small to medium-sized buildings. They feature a lightweight, compact design and a liquid-filled gauge for accurate pressure measurements. They can also be used for small and medium-sized applications in a variety of plumbing, fire safety, and irrigation systems. Each model includes a supply hose and regulator.

Flow Rates

Flow rates of hydrostatic testing pumps vary. This is because different machines have different capabilities. A pump must have a specific pressure range to perform its test. Most pumps use a plunger or piston-type pumps. These pumps work best when water pressure is pressurized. Pumps can also use gravity feed. To use gravity feed, place the pump at a lower elevation than the water source and turn it on with the priming valve open. This will eliminate the need for a shaft in an older machine. Direct attachments have fewer moving parts, require less maintenance, and are lighter in weight.

Flow rates of hydrostatic testing pumps vary by manufacturer. When selecting a pump, consider the number of applications it will serve. If a particular hydrostatic testing company provides services for many industries, it will need several different pumps for different tests. Make sure to choose one that meets the specifications and pressure range of the testing job. Flow rates are important for determining if a pump can deliver the desired amount of water.

What You Need to Know About Hydrostatic Testing PumpsCost

When buying a hydrostatic testing pump, it is essential to find one with the right features and specifications. Often, you can customize the pump with the right accessories. Accessories can increase the unit’s value and minimize liability costs associated with heavy lifting. For example, pressure feed tanks eliminate the need for 55-gallon drums and save on time and labor costs. However, you must be careful about the GPM rating of the pump.

Hydrostatic test pumps are one of the most popular pressure testing pumps. They test the fluid pressure in various systems, including sewage and effluent pumps. Plumbing contractors and pipefitters are some of the most common users. Other professionals include engineers and warehouse workers. Hydrostatic testing pumps are ideal for determining water or fluids flow rate through piping systems. They are also used as calibration sources for high-pressure input devices, such as pressure transmitters and gauges.
