single stage vs two stage hydraulic pump made in china

A single stage hydraulic pump is a pump that uses a single impeller to generate flow, while a double stage hydraulic pump uses two impellers in series to generate flow. This means that the double stage hydraulic pump has more pressure output than a single stage hydraulic pump of the same size, but it also means that it is typically larger and more expensive. Double stage hydraulic pumps are often used in high pressure applications where a high level of pressure is required to operate the hydraulic system.

A single stage hydraulic pump is typically used in applications where a moderate level of pressure is required, such as in a hydraulic system that is used to operate a lift or a small crane. These pumps are relatively simple in design and are often less expensive than double stage pumps.

Double stage hydraulic pumps, on the other hand, are typically used in applications where a high level of pressure is required, such as in a hydraulic system that is used to operate a large piece of heavy machinery or a hydraulic press. These pumps are more complex in design and are often more expensive than single stage pumps. The increased complexity and cost of double stage pumps is due to the fact that they have two impellers instead of one, which allows them to generate higher pressure.

The main advantage of a double stage hydraulic pump over a single stage pump is its ability to generate higher pressure. This makes it suitable for applications where a high level of pressure is needed to operate the hydraulic system. Additionally, double stage pumps are typically more efficient than single stage pumps, which means they can produce more flow with less input power. This can result in energy savings and can make the hydraulic system more efficient overall.

However, there are also some disadvantages to using a double stage hydraulic pump. As mentioned earlier, these pumps are typically more complex and more expensive than single stage pumps. They are also generally larger and heavier, which can make them more difficult to install and maintain. Additionally, the increased pressure output of a double stage pump can put more stress on the other components of the hydraulic system, which can lead to increased wear and tear and a shorter lifespan for the system overall.

It is difficult for me to provide a comparison of the performance data for single stage and double stage hydraulic pumps without more specific information about the pumps in question. The performance of a hydraulic pump can vary depending on a number of factors, such as the size and design of the pump, the type of fluid it is designed to work with, and the pressure and flow requirements of the hydraulic system it is used in. In general, however, a double stage hydraulic pump will have a higher pressure output than a single stage pump of the same size, but it will also typically have a lower flow rate. This means that a double stage pump is better suited for applications where high pressure is required, but a lower flow rate is acceptable.

Customers often ask, “when do I need a two-stage hand pump versus a single-stage hand pump?” Well, that depends on the type of work you are trying to do inside your hydraulic system. There is a measurable difference between the two of them and both have benefits depending on the application. To explain, let’s look at the new PowerX International line of hand pumps.

First up is the PowerX P43 single-stage 10,000 psi (700 bar) hand pump. The reason why it is called a “single-stage” pump is because the flow of oil produced is the same on each stroke of the handle. For the PowerX P43, the flow is a continuous 0.20 in3 of oil per stroke. The pumps flow rate remains constant, whether it is simply raising a single acting cylinder with no weight on it, or pushing 10 tons at 10,000 psi. A single-stage pump is great if your hydraulic ram does not have to travel far before it starts to lift or push the load. But if the ram needs to travel any significant distance to meet the load, there would be a lot of excessive pumping by the operator before they actually started to do any work. This would get tiresome very quickly!

Enter the PowerX P37 “two-stage” 10,000 psi (700 bar) hand pump. Two stage hydraulic hand pumps give the operator higher flow rates up until the cylinder or ram starts to do work. In the case of the PowerX P37 hand pump, the first stage has a flow of 0.79 inches3 of oil per stroke (almost 4 times more than the P43) before making contact with the work load where the pressure builds. Once the ram makes contact with the load, and the pressure inside the system raises above 200 psi, the second stage kicks in at 0.17 in3 of oil volume. This two-stage pump allows the operator to do less work (or hand pumping) before coming into contact with the load. Your operators will thank you!

Both the PowerX P43 and the PowerX P37 are built with rugged steel construction and both have internal pressure relief valves to protect against overload. To learn more about the PowerX line of 10,000 psi (700 bar) hand pumps, click here.

Our range of single-stage pumps can be designed either using the end suction overhang impeller design method, or the impeller between bearing design method. These pumps comply with either ISO 5199 / ISO 2858, ASME B73.1 or API 610 standards and guarantee reliable pumping processes.

2-stage hydraulic pumps are used in motor-driven operations wherein a low-pressure, high rate inlet must be transferred to high pressure, low flow-rate outlet. Single-stage pumps are rated to a static max pressure level and have a limited recycle rate.

To achieve high pressure without a 2-stage unit, the drive engine would require significantly higher horsepower and torque capacity but still lack an effective cycle rate. Other hydraulic pump variants exist – such as piston pumps – but are expensive, making 2-stage units more feasible.

For example, a single gear hydraulic pump might be designed to generate a high-pressure output. Still, it will be unable to repeat a cycle rapidly due to a necessarily low flow rate at the intake. A 2-stage unit ensures consistent flow to increase cycle turnover.

Compactors utilize a similar 2-stage process. High-pressure flow drives the compacting rod, while the low-pressure flow retracts the mechanism and feeds the high-pressure chamber for repeated impacts.

2. Once the first-stage pressure meets a certain pressure threshold, a combiner check valve will open and feed into the second-stage, small-gear unit – joining flows at relatively low pressure.

A piston pump operates according to variable displacement. Flow is determined by the angle of an internal slant disk attached to the pump shaft. Pump adjustments – like torque or horsepower limiters – allow piston pumps to emit a max flow rate regardless of pressure level.

In most cases, hydraulic piston pumps are an order of magnitude more expensive than gear-based pumps. Potential downtime and part replacement in high volume work conditions exacerbate price disparities further.

Chiefly: fuel and power consumption. A piston pump operating in high-pressure ranges will regularly demand the full horsepower capabilities of its associated drive engine – increasing the power utilization of the system.

Opportunity cost may also be considered when using a piston pump. Depending on the application (e.g., log splitting), work output can be heavily impacted by the cycle speed of the pump. Not only is a piston pump more expensive to peruse, it is also slower than 2-stage pumps.
