A positive displacement pump is used for high pressure and low discharge, while a centrifugal pump is used for low pressure and high discharge.
High pressure and low discharge pumps are used in various industries and applications to move fluids at a low rate, yet at high pressure. Knowing which type of pump to use, its specifications and characteristics, and its maintenance and safety considerations are important factors to consider when choosing a pump for a given application. In this blog post, we will discuss what high pressure and low discharge is, the types of pumps used for these applications, the general specifications and characteristics of the pumps, the advantages, applications, maintenance, safety precautions and cost considerations of these pumps, and which pump is best for high pressure and low discharge.
What is High Pressure and Low Discharge?
High pressure and low discharge refer to the pressure and flow rate of a pump system. High pressure occurs when the pressure of the system is too high, while low discharge is when the flow rate is too low.
When a system has high pressure, it is usually caused by an insufficient compressor, a leaking discharge valve, or a damaged discharge valve. High pressure can also occur when the evaporator pressures are low and the compressor is having to work harder to maintain the pressure.
Low discharge can be caused by a number of factors, such as a blocked filter, a valve not opening properly, or a malfunctioning pump. Low discharge can also be caused by a low flow rate from the pump, which can be due to a malfunctioning pump, a pump not being sized correctly for the system, or a pump being too old or worn.
The best way to prevent high pressure and low discharge is to ensure that all the components of the system are regularly maintained, the filters are cleared and the pumps are correctly sized and in good working order. High pressure and low discharge can also be avoided by using a high-pressure suction pump, which is designed to provide a higher flow rate with lower pressure.
Types of Pumps Used for High Pressure and Low Discharge
To answer this question, it is important to understand the different types of pumps used for high pressure and low discharge.
Centrifugal Pumps
Centrifugal pumps are a type of pump used for high pressure and low discharge applications. These pumps use an impeller to draw in liquid, which is then accelerated by the impeller’s rotation and released at a higher pressure. Centrifugal pumps are typically used in applications where the pressure requirements are relatively low, such as pumping water or other liquids.
They are also used in applications that require a higher pressure, such as pumping fuel or other fluids. The main advantage of centrifugal pumps is their ability to move large volumes of liquid quickly and efficiently, with relatively low pressure. Additionally, centrifugal pumps are relatively simple to maintain and operate, making them an economical choice for many applications.
Reciprocating Pumps
Reciprocating pumps are a type of positive displacement pumps that are commonly used for high pressure, low discharge applications. They work by using a piston, plunger, or diaphragm to move a liquid or gas from one area to another. This type of pump is ideal for applications where precise and accurate control of flow is required and where high pressure is needed.
In addition to their high pressure capabilities, reciprocating pumps are also known for their reliability, durability and efficiency. They are also often used in industrial settings due to their ability to handle a variety of fluids and gases.
Diaphragm Pumps
Diaphragm pumps are one of the most commonly used pumps for applications requiring high pressure and low discharge. This type of pump utilizes a flexible diaphragm that is pushed and pulled to create suction and pressure, thereby allowing for increased pressure capabilities. They are extremely useful for applications that require a steady and reliable flow, such as chemical processing, water treatment, and industrial cleaning. Additionally, they are incredibly energy efficient and require minimal maintenance, making them an ideal choice for many industries.
General Specifications and Characteristics of High Pressure and Low Discharge Pumps
When it comes to selecting a pump for your application, knowing the general specifications and characteristics of high pressure and low discharge pumps is essential. High pressure and low discharge pumps are used in a variety of applications, including industrial, agricultural, and residential settings.
High pressure pumps are designed to produce higher discharge pressures than low pressure pumps and are typically used in applications that require a high pressure output, such as firefighting systems, power plants, and water treatment systems. These pumps are constructed with robust materials that can withstand the high pressures they are designed to produce. The pumps are also equipped with pressure relief valves that are designed to ensure that the pressure does not exceed the desired level.
Low discharge pumps are designed to create a lower pressure than high pressure pumps and are typically used in applications that require a lower pressure output, such as residential or agricultural water systems. These pumps are designed to produce a lower flow rate compared to high pressure pumps and are typically constructed with lightweight materials, such as plastic or aluminum, making them easy to install and maintain. Low discharge pumps are also equipped with pressure relief valves to ensure that the pressure does not exceed the desired level.
When selecting a pump for your application, it is important to consider the general specifications and characteristics of high pressure and low discharge pumps. Knowing which type of pump is best suited for your application will help you make the best decision for your needs.

Which Pump is Best for High Pressure and Low Discharge?
When it comes to selecting the right pump for high pressure and low discharge, it is important to consider the type of pump that best suits your needs. Centrifugal pumps are the most common choice for low viscosity fluids as they are designed to transfer fluid at high flow rate and low pressure. However, other types of pumps have their own benefits and can be better suited for certain applications.
For example, axial flow pumps, also known as propeller pumps, are ideal for high flow rates and low pressure. These pumps are best for continuous flow, metering, and dosing functions. Gear pumps may also be appropriate, as they are able to handle viscous fluids and provide a higher pressure output. Pressure gauges can be used to measure the pressure in the system, and a pressure switch can be used to shut off the pump when the pressure is too high.
When it comes to high pressure and low discharge, it is important to select the right pump for your application. Booster pumps are best for low water pressure, while misting pumps are more suitable for high pressure but low flow rate applications. It is also important to consider the efficiency of the pump, as low flow high head pumps running at higher speeds offer the best efficiency.
In conclusion, selecting the right pump for your application is key to achieving high pressure and low discharge. By taking into account the type of pump and its efficiency, you can ensure you have the right pump for the job.
Conclusion
In conclusion, there are several types of pumps that can be used for high pressure and low discharge applications.
