Pressure Test Pump is a device that uses a high pressure pump to conduct hydraulic tests on pipeline systems, primarily to verify their sealing integrity, strength, and reliability. Below is a detailed introduction to pressure test pumps:
1.Working Principle
The fundamental operating principle of a pressure test pump is based on positive displacement, with the most common types being piston pump and plunger pump. It works through the reciprocating motion of pistons or plungers, drawing water in through the suction port and then forcibly compressing it into the pipeline. As water is continuously injected, the pressure inside the pump gradually increases until it reaches the required test pressure. The pressure test pump maintains this pressure, and engineers monitor the pressure gauge readings over a specified period to determine whether the system is functioning properly.
2.Safety and Quality Control
Strength Verification: Ensures that materials and equipment can operate safely and normally even under pressures exceeding the working range.
Leak Check:After stabilizing the pressure with the test pump, observe whether the pressure remains stable within a specified time frame and check for any signs of leakage.
Standard Compliance:The product must meet industry regulations and comply with national standards.
3.ApplicationThe test pump plays a critical role in the application of blowout preventers (BOPs). Its primary function is to verify whether the BOP can effectively seal the wellhead under high pressure, thereby preventing potential accidents.
4.Precautions
Personnel must keep a safe distance during the test to avoid explosion hazards.
Do not exceed the pressure limit that the test piece can withstand.
Pressurization and depressurization must be carried out slowly.
The pressure test pump is a core tool for ensuring engineering safety and quality inspection. The Elephant pressure test pump can effectively and controllably increase pressure, allowing pipeline systems to gradually and steadily adapt to rising pressure levels. It ensures stable pressure, preventing abnormal pressure values during testing, and is equipped with an overpressure protection system that prioritizes safety while reducing risks in pressure testing.Finally, we warmly welcome you to choose our Elephant reciprocating pump products.

The jet pump and the plunger pump are two different types of pumps, with the main differences reflected in the following aspects:
1.Working Principle
Jet Pump: It is a fluid pressurization device that primarily utilizes high-pressure working fluids (water, air, steam) to generate a high-speed jet through a nozzle, which enters a high-pressure chamber, thereby increasing the pressure to meet operational requirements. It relies entirely on the dynamic motion between fluids. It has strong self-priming capability and can handle gas-liquid mixed fluids.
Plunger Pump: The motor drives the pump's crankshaft to rotate via large and small pulleys and a narrow belt. The crankshaft then drives the connecting rod and plunger to perform reciprocating motion. When the plunger moves backward, the inlet valve opens, allowing liquid to enter the pump body until the plunger reaches its rearmost position (180° rotation of the crankshaft), completing the suction process. The plunger then begins to move forward, compressing the liquid in the pump's valve chamber, increasing the pressure. As a result, the inlet valve closes, and the discharge valve opens, allowing the liquid to be pushed out by the plunger through the discharge valve. The flow rate can be adjusted by changing the size of the plunger.
2.Structural Differences
Jet Pump: Simple in structure, primarily generates power through fluid movement, with lower maintenance costs in the long run (no vulnerable parts) and lower sealing requirements.
Plunger Pump: Mainly generates power through the reciprocating motion of the plunger. Compared to the jet pump, it has higher long-term maintenance costs and extremely high sealing requirements to prevent plunger leakage.
3.Application Scenarios
Jet Pump: Deep well water extraction, chemical industry (capable of transporting corrosive media,etc).
Plunger Pump: High-pressure cleaning, petroleum industry (mud pump, water injection pump, etc.), water well drilling, etc.
The jet pump primarily relies on hydrodynamic force for operation, making it suitable for simple working conditions and offering corrosion resistance. On the other hand, the plunger pump operates through the reciprocating motion of a plunger, making it ideal for high-pressure, high-efficiency, and stable-flow applications. You can choose the appropriate pump based on different working conditions and requirements. Elephant Machinery offers both plunger pump and jetting pump in our product lineup.

Friendly reminder: In recent days, temperatures have risen sharply, and high temperatures may lead to machine overheating, lubrication failure, seal failure, and other issues. In severe cases, it may even cause power outages or machine shutdowns. To ensure the normal operation of the reciprocating pump, the following measures will be taken:
1.Enhance Heat Dissipation- Ensure the pump is well-ventilated during operation. If the ambient temperature is high, use ventilation equipment (fan) for cooling.- Avoid direct sunlight exposure. When using a reciprocating pump outdoors, employ a sunshade (or canopy) to prevent direct sunlight.
2.Lubrication Maintenance- Replace high-temperature lubricating oil to prevent viscosity reduction under high temperatures.- Increase the frequency of lubricant changes. In high-temperature climates, lubricants may degrade and oxidize. Check for impurities in the oil and observe if its color changes. Replace immediately if any changes are detected.
3.Motor Protection- Regularly inspect the cooling system of the motor to ensure proper functioning and prevent burnout due to power failure.
4.Seal Inspection- Seals are vulnerable components in reciprocating pumps. High temperatures can accelerate their wear and shorten their service life. Regularly inspect the seals for wear and check for any leaks. Replace them promptly if any issues are detected.
5.Operator Training- Enhance emergency training for operators to enable them to determine whether the pump is functioning normally based on factors such as motor noise, vibration, and smoke, and to master corresponding response measures.
The measures mentioned above can effectively mitigate the impact of high temperatures on reciprocating pumps. We urge all customers to take such situations seriously and jointly prioritize on-site safety and the stable operation of equipment.Additionally, our Elephant reciprocating pumps can be optionally equipped with an intelligent unattended pump station system. This system supports unmanned operation, features temperature sensors for high-temperature early warning, enables multi-terminal remote monitoring, and ensures real-time data synchronization. Moreover, it offers remote start/stop, speed adjustment, data retrieval, automatic power-off, and alarm functions, significantly improving operational efficiency.We welcome inquiries and purchases!

Piston pumps and reciprocating pumps are two common types of pumps used for compressing and transferring liquids, and there are some differences in their principles of operation and construction.
A Piston Pump (Plunger Pump) is a type of pump that generates pressure through the reciprocating motion of a piston in a cylinder. It usually consists of one or more pistons and corresponding piston rods that generate pressure through reciprocating motion, drawing liquid in through the inlet and discharging it through the outlet. Piston pumps typically have high working pressures and low flow rates, and are suitable for application scenarios that require high pressure and low flow rates. Piston pumps are generally simple, stable and reliable, and have a long service life.
Reciprocating Pump is a pump that generates pressure by reciprocating a plunger or piston. Reciprocating pumps are usually composed of a plunger or plunger piston, a gas spring and so on. As the plunger or piston moves forward, liquid enters the pump chamber through the inlet, and then the plunger or piston moves backward, discharging the liquid through the outlet. Reciprocating pumps can provide a high flow rate, but the working pressure is relatively low. Reciprocating pumps are suitable for application scenarios that require high flow rates and medium or low pressures.
Overall, piston pumps are suitable for high-pressure, low-flow operating conditions, while reciprocating pumps are suitable for higher-flow, medium- or low-pressure operating conditions. The choice of which pump to use depends on the specific application requirements and operating conditions.
