Reciprocating crude oil transfer pump use pistons or plungers to move back and forth in cylinders to suck in and pump out crude oil. Crude oil transfer pumps are especially important in the petroleum industry.   Working Principle: The piston or plunger moves back and forth within the pump chamber of the crude oil transfer pump. When the piston or plunger moves backward, the cylinder becomes a vacuum state, the pump chamber volume increases, and the pressure decreases, causing the crude oil to be drawn into the pump chamber through the suction valve. When the piston or plunger moves forward, the pump chamber volume decreases, the crude oil is compressed, the pressure increases, and the discharge valve opens, allowing the crude oil to be discharged into the transfer pipeline. When the reciprocating motion repeats inhalation and exhalation, continuous crude oil transfer is achieved.   Features: High pressure: It can generate high pressure to meet the needs of some high-pressure working environments, such as oil well services, long-distance pipeline transportation, refineries, oilfield gathering and transportation, etc. Suitable for high-viscosity crude oil: Compared to centrifugal pump, reciprocating pump is more suitable for transporting high-viscosity crude oil. When the piston or plunger moves back and forth, it can effectively push the crude oil forward. High stability: The compact structural design of reciprocating pumps ensures stability and reliability during the pumping process. Due to their working characteristics, reciprocating pumps are less prone to flow fluctuations when pumping high-viscosity crude oil, enabling them to maintain constant pumping efficiency. These pumps can also be flexibly adjusted to meet actual flow requirements, making them suitable for a variety of complex operating conditions. Strong self-priming capability: Reciprocating pumps have a strong self-priming capability and can suck crude oil without the aid of other equipment. Intelligent pump station system: Features unattended operation, multi-segment remote monitoring, and real-time data synchronization. It also supports remote start/stop, speed adjustment, and data retrieval.   Daily maintenance: Regularly check the seals to prevent crude oil leaks, avoid safety accidents, and reduce resource waste. Regarding component wear and tear, regularly check and replace components according to the user manual to ensure the normal operation of the pump. Regularly add lubricating oil to components that require lubrication to reduce component friction.     Crude oil transfer pumps play a vital role in the petroleum industry, particularly in applications requiring high pressure, stable flow rates, and the transfer of high-viscosity fluids.

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.
