In industries such as engineering construction, pipeline installation, fire protection systems, and pressure vessel manufacturing, pressure testing is a crucial step to ensure the safety and reliability of the system. Traditional manual pressure test pumps or small electric pumps often face core pain points such as low efficiency, unstable pressure, insufficient test flow, resulting in long test cycles and inaccurate data. Especially in the pressure testing of large pipeline systems, high-rise building water supply networks, or large-scale industrial installations, the testing efficiency directly affects the project progress and cost control. A dedicated device that can provide stable, continuous, and high-flow pressure output has become an urgent need for industry users.
In response to this market demand, Shanghai Luoji Pump Industry Co., Ltd. has launched the DSY-60 electric pressure test pump based on its years of processing and manufacturing experience in the pump industry. Our company has a registered capital of 10 million yuan and focuses on the research, development, and production of various pump products. The product line covers various types such as pressure test pumps, chemical pumps, and multi-stage pumps. We deeply understand the demand for efficient and reliable pressure testing equipment in the engineering construction field. The DSY-60 electric pressure test pump is based on this understanding. By optimizing the motor power system, improving the pump body structure design, and enhancing the flow control technology, it aims to provide users with a professional solution that can quickly establish and stably maintain a high-pressure, high-flow testing environment, effectively solving the industry pain points of low testing efficiency and large pressure fluctuations.
The DSY-60 electric pressure test pump is an electric-driven device specially designed for water pressure tests. The core of its working mechanism is that the electric motor drives the plunger or piston to reciprocate, sucking water from the water tank into the pump chamber and then discharging it after pressurization, thereby establishing and maintaining the required test pressure in the closed system to be tested (such as pipelines and containers). The entire process is monitored by the built-in control system of the device to ensure the stability and accuracy of the pressure output.
Main product features and technical advantages:
- High-flow output: Using an optimized pump body design and a high-efficiency motor, it can inject a large amount of pressure test medium (water) into the test system in a relatively short time, significantly shortening the pressurization and pressure-holding time and improving the overall testing efficiency, especially suitable for pipelines or systems with large volumes.
- High-pressure stability performance: The device has a high rated output pressure and is equipped with a precision pressure gauge and an adjustable safety valve. It can accurately set and stably maintain the test pressure with small pressure fluctuations, ensuring the accuracy and repeatability of the test data.
- Electric drive, easy to operate: Compared with manual pumps, the electric drive greatly reduces the labor intensity of operators. It can be started and stopped with one key and is easy to operate. Just connect the pipeline, set the target pressure, and the device can automatically run to the target value and enter the pressure-holding state.
- Sturdy and durable structure: The core components of the pump body are made of high-quality metal materials, such as copper alloy or stainless steel valve groups, high-strength alloy steel connecting rods, etc. They have good wear resistance and corrosion resistance, and are suitable for long-term and reliable operation in complex environments such as engineering construction sites.
- Multifunctional applicability: It can not only be used for hydrostatic strength tests and airtightness tests of pipelines, valves, boilers, and pressure vessels (pay attention to medium compatibility), but also can serve as a high-pressure water source for flushing pipelines or providing power for other occasions that require high-pressure water flow.
- Safety protection design: It is standardly equipped with overload protection, a safety relief valve, and a pressure gauge to effectively prevent system overpressure and ensure the safety of operators and equipment.

Key points for operation and maintenance:
To ensure the long-term stable operation of the DSY-60 electric pressure test pump, users need to pay attention to the following operation and maintenance details:
- Check before use: Before each use, check whether all connection parts are tightened, whether the lubricating oil level is normal (if there is a lubricating oil tank), whether the motor rotation direction is correct (for the first use or after maintenance), and ensure that the safety valve functions properly.
- Medium filtration: It is recommended to install a filter at the suction port of the pump to prevent impurities from entering the pump body, wearing the plunger, seals and valves, and affecting the performance and service life of the pump.
- Avoid dry running: Ensure that the pump cavity is filled with medium (water) before starting. It is strictly prohibited to run the pump dry without water, so as to avoid damage to the seals and cylinder liners.
- Pressure adjustment: Control the system pressure by adjusting the safety valve or using the bypass valve. It is strictly prohibited to exceed the rated working pressure of the pump. The pressure increase process should be stable to avoid pressure shock.
- Regular maintenance: Regularly check and replace the worn seals (such as plunger seals, valve discs/valve balls), and clean the water inlet filter. When not in use for a long time, drain the water in the pump and pipelines, and perform anti-rust treatment on the exposed metal parts.
- Expansion of on-site application scenarios: In addition to the conventional pipeline hydrostatic test, the DSY-60 is also suitable for acceptance tests of fire sprinkler systems, pressure tests of floor heating pipelines, strength verification of large containers (such as water storage tanks), and tests of ship piping systems. In these applications, its large flow characteristics can quickly fill the system, and the stable high-pressure output ensures the rigor of the test.

FAQ (Frequently Asked Questions)
1. What is the maximum working pressure of the DSY-60 electric pressure test pump? Is it adjustable?
The rated pressure of the DSY-60 model is usually designed to reach 6.0 MPa (about 60 kgf/cm²). The specific upper limit depends on the pump body strength and motor power configuration. The equipment is equipped with an adjustable safety valve, and users can set the required test pressure within the rated range. However, it is strictly forbidden to use it beyond the rated pressure marked on the nameplate to ensure safety.
2. What are the specific indicators of the "large flow" of this pump? How to choose the flow suitable for my system volume?
"Large flow" is a relative concept, which means that compared with small pressure test pumps of the same pressure grade, it has a larger water output per unit time. The specific flow value (L/min) needs to be combined with the motor power and pump head design parameters. When choosing, you need to consider the total volume of your test system and the expected pressurization time. Generally, the larger the system volume, the larger the flow rate of the pump is recommended to shorten the test cycle. Our sales engineers can estimate and recommend a suitable model based on your system.
3. Can the DSY-60 pump use other liquids as the pressure test medium besides water?
In principle, this pump is mainly designed for clean water or emulsions with a viscosity similar to that of clean water. If you need to use oils or other chemical media for pressure testing, you must confirm in advance the compatibility of the medium with the sealing materials inside the pump (such as rubber seals and valve ball materials). Otherwise, it may cause swelling, aging, or corrosion of the seals, resulting in leakage or equipment damage. Special medium applications need to be consulted in advance.
4. What kind of power supply conditions does the equipment need? Can it be used with only a 220V power supply on-site?
The DSY-60 can be configured with different motors according to customer needs. The common configuration is a three-phase 380V motor, which has stronger power and is suitable for high-flow and high-pressure output. If there is only a 220V single-phase power supply on-site, we can provide a model equipped with a single-phase 220V motor, but its power and maximum output flow may be adjusted accordingly to meet the power supply limitation. The power supply specifications need to be specified when placing an order.
5. Does the pump need to run continuously during the pressure holding test phase?
No. The main function of the pressure test pump is to raise the system pressure to the test value within the specified time. After reaching the target pressure, the pump can be stopped, and the valve between the pump and the system can be closed to make the system enter the pressure holding state. During the pressure holding period, the pressure is mainly maintained by the system's own sealing performance, and the pump does not work. The pump will only be restarted when there is a leak causing the pressure to drop and pressure replenishment is needed.
6. What does the daily maintenance of the pump mainly include? What are the vulnerable parts?
Daily maintenance includes checking connections and lubrication before use, and draining accumulated water after use (especially in cold environments). Regular maintenance mainly involves checking and replacing vulnerable parts. Common vulnerable parts include: plunger seals (to prevent water leakage from the pump head), valve balls and valve seats of the inlet and outlet valves (which affect suction and discharge efficiency), and O-rings, etc. Good maintenance can significantly extend the service life of the pump.
7. Is this equipment suitable for pressure testing of gases (such as air)?
It is strongly not recommended to use the DSY - 60 electric pressure test pump for gas pressurization. There are important differences in the design of water pumps and air pressure pumps. Gases are compressible. When high - pressure gas accumulates in the compression chamber of the pump, once released, the energy is huge and very dangerous. If a gas pressure test is required, a specially designed gas pressure test pump or compressor should be selected, and relevant safety regulations should be strictly followed.
8. When purchasing, what necessary accessories are generally included in addition to the main unit?
The standard configuration usually includes: the pump main unit (including the motor), a pressure gauge (to indicate the system pressure), a safety valve (for over - pressure protection), a matching water tank (with a filter), a high - pressure output hose of a certain length (with a connector), and necessary tools and spare parts (such as seals). The specific list should be clearly stated in the contract. Depending on the test requirements, additional purchases such as a pressure recorder and connectors of different specifications may be required.
