A hydrostatic test pump is a tool that inspectors use to check pipes for leaks. These pumps are designed to be portable and easy to operate. They come with a gauge reading up to two times the maximum pump pressure. They are also lightweight, so they are easy to transport and maneuver.
They are Easy to Operate
Whether testing new or old pipes, a hydrostatic test pump is the fastest way to check for leaks. It’s easy to operate and can be plugged into any electrical outlet. Some models even have a built-in bypass to prevent over-pressurization. Many hydrostatic test pumps use an electric motor that’s UL certified. It’s a simple process to prime the pump by connecting a standard garden hose. Most models also feature a gauge to show pump pressure and an inlet to withstand high pressures. Depending on the model, some hydrostatic test pumps include long lengths of cable that make it easier to connect to fire systems during testing. Some are also compatible with standard extension cords for added flexibility. These extensions are essential when you’re working in large buildings.
They are Durable
For those who need to complete high-pressure calibration tasks with a short turnaround time, the durability of a hydrostatic test pump is essential. This type of pump generates calibration pressures up to 10,000 psi and can be used with pressure transmitters or pressure gauges. The best hydrostatic test pumps feature a gauge filled with liquid, such as silicone or glycerin, which helps stabilize the needle and limit condensation buildup. It also lubricates the gauge and guards against sudden temperature changes. In addition, a good test pump should have a gauge that can read up to two times the maximum pump pressure. That way, it won’t take longer than necessary to fill or pressurize a system, according to Wheeler-Rex. This saves time and money.
They are Affordable
Whether used to test fire sprinkler lines or plumbing, hydrostatic testing pumps are an affordable way to ensure a system is structurally sound and ready for action. Many fire safety inspectors depend on these devices to identify issues that may need to be apparent with a visual inspection. The most affordable models are electric, requiring little more than an outlet and plug. Some pumps offer a gauge that indicates the pressure of water being delivered to the system, while others maintain system pressure after the pump shuts off using an in-line check valve. Manufacturers also offer varying lengths of inlet, or supply, hoses to accommodate different applications.
They are Easy to Maintain
Whether you are testing fire sprinklers, DOT-required containers, or water lines, hydrostatic test pumps are easy to maintain. They come in various sizes and pressure ranges, so there is a model to meet every job site’s needs. They also are designed for easy mobility. Contractors can choose from plug-in electric, battery power, or gas-powered pumps. They should pay attention to the maximum pressure and volume the pump can deliver and any other specifications for the model they select. Once the pump is connected to a system, contractors must monitor the gauge for leaks while watching the pressure rise to the desired level. Once the system reaches the desired stress level, it will need to be slowly depressurized to prevent any sudden changes in pressure that could damage the system.
