Piston pumps are devices that can be seen in many industries. Using pistons to create pressure by forcing fluid into an area with less volume, they can move liquids or gases that have high pressure. They are used by numerous enterprises across a range of industries, including oil and gas companies, chemical facilities, water treatment plants, food processing warehouses, and more.
However, due to the number of models available on the market, it may be difficult for you to choose which one is best for your company. Lucky for you, at Compresstech Resources, Inc., we can provide you with piston pumps in the Philippines. Count on our team to provide you with high-grade machines that best meet your needs and preferences.
What Is a Piston Pump’s Working Principle?
Positive displacement pumps can be categorized into two main classes: reciprocating and rotary. In particular, two types of piston pumps (pneumatic or hydraulic ones), can transfer liquids and gases from a low-pressure area to a high-pressure one. It does not rely on the weight of the liquid to generate pressure, as in a gravity feed system, but instead uses energy to create pressure. As a result, it can provide a constant flow at a fixed speed regardless of any changes in pressure
How Does a Piston Pump Function?
Although there are many types available, piston pumps are usually made of three main components: a piston, cylinder, and rod. These machines have an all-weather drive motor above the wellhead, which is connected to other downhole components. When turned on, the motor pushes and pulls a drive rod connected to a reciprocating piston near the bottom of the well.
As a result, a low-flow pumping action occurs below the wellhead, pulling liquid from the well. The drive rod, which is enclosed in a cylinder, connects the motor to the piston in a pump barrel. When the device is used, the motor pulls up the rod and creates a suction at pump intake, pulling the liquid through a strainer into the foot valve.
The stainless steel balls in the reciprocating piston and foot valves also open naturally to allow liquid into the other piston, before closing to prevent liquid from returning. Lastly, the pumping action lifts liquid up the riser pipe with each stroke, enabling the liquid to exit a discharge tee above the wellhead.
Both vacuum and hydraulic pumps have many advantages over other types of pumps. Aside from their efficiency, they can push fluids at higher pressures with less energy consumption. This makes them preferable for businesses as they can help lower your electricity bill and save you more money in the long run.
Where Are Piston Pumps Used?
Here are a few applications where different types of piston pumps are used:
These heavy equipment machines are utilized to dig and move soil in addition to other materials. Currently, some models use powerful piston pumps to push the excavated material out of the way. All the pumps used for this function also have horsepower, stand-by, and variable gain L/S controls.
In addition, excavators can either be tracked or wheeled. The tracked ones are considered more powerful and can operate in more challenging terrain. However, it is heavier and needs a wide turning radius to maneuver on site. In comparison, wheeled excavators are lighter, but they can’t operate in as many different types of terrain as tracked models.
In-Plant Pump Stations
Wastewater treatment plants have stations where positive displacement pumps are used for primary, thickened, and digested sludge, slurries, and chemical feed. The equipment and systems utilized for these applications are usually installed in an enclosed structure. While custom-designed ones have a capacity ranging from 76 lpm (20 gpm) to more than 378,500 lpm (100,000 gpm), pre-fabricated stations typically only handle up to 38,000 lpm (10,000 gpm).
The most common pump controls have liquid level indicators that alert you when the wet well has reached a desirable water level. Some pump stations even have a trapped air column or bubble system to monitor pressure levels in the system. It is also important to note that there are other control alternatives, such as electrodes placed at cut-off levels and float switches.
Used to refer to all the different types of pumps used in large vessels, marine pumps are complex systems that have the primary purpose of cooling, heating, and lubricating. The liquids circulated are essential as they ensure that the ship has a safe voyage ahead. Additionally, the staff on these watercrafts need to monitor the viscosity, density, surface tension, and compressibility to ensure that the machines are performing in their optimum condition.
Specifically, positive displacement pumps are commonly used for lubricating oil duties because of their self-priming ability. The models usually found on vessels are those that are mounted, short, direct, and generously dimensioned. Additionally, depending on the ship’s manufacturer, some boats have centrifugal pumps rather than positive displacement pumps since both these types have similar characteristics.
Ink Transfer Pumps
Pneumatic and hydraulic piston pumps are used in the printing industry to transfer different types of fluids, such as liquid ink, heavy ink, and solvents used for flushing. Companies with this nature of business tend to choose reliable machines with low pulsations to ensure that the fluids handled by the devices aren’t overmixed.
Some of the applications they use piston pumps for include transferring water-based or solvent-based ink from ink pails or drums to printing machines, moving solvents from barrels to vessels for cleaning or flushing, and sending lacquer from barrels or tanks to coating machines.
Commonly used for medical, agricultural, and water treatment purposes, peristaltic pumps are machines that have a flexible hose fitted inside their pump casing. The alternating compression and relaxation of the tube draws content in and propels products away from the pump.
Peristaltic pumps also have a rotating shoe or roller that passes through the hose length when activated. As a result, this mechanism creates a temporary seal between the suction and discharge sides. The sealing pressure also moves along the tube to force the product to be displaced as the rotor turns.

Safety Tips When Using Piston Pumps in the Philippines
Before you start operating your piston pump, make sure to observe the following safety precautions so that your machine will last you for years to come:
Read the Manual Carefully
Most instruction manuals can be intimidating to read, especially since they can come in thick packets. However, it is essential that you take the time to do so to ensure that you know all the things you can and cannot do with your fluid handling unit.
Reading the instructions can also lessen the time you use to set up the machine, since now, you can get everything done right the first time. This means you can say goodbye to any frustrating moments that may occur just because you didn’t press the correct button or flip the right switch.
Only Allow Trained Personnel To Operate the Unit
Piston pumps are usually installed alongside machines like water and oil hydraulics, industrial processing equipment, and high-pressure cleaning devices. To ensure that your system doesn’t encounter any problems, assign only trained personnel to operate the unit. They can be employees who know the intricacies of the model you chose as well as the network it is part of, or they can be those who have undergone the needed coaching or schooling beforehand. Doing so reduces the chances of any malfunctions affecting your bottom line.
Never Neglect Preventive Maintenance
You must regularly conduct preventive maintenance on the piston pump. This will help you save money, time, and effort since it will prevent more serious problems, helping you avoid paying for expensive repairs. Aside from this, it is incredibly beneficial for the safety of your employees as it ensures that your industrial-grade machines are working in optimum condition and are not prone to overheating or combustion.
Some of the most common things you can do include:
• Ensure that your piston pump parts meet original equipment manufacturer specifications
• Make sure that the piston shoe subassembly diameter matches with cylinder bore diameters
• Have your cylinder block lapped and treated
• Test your pump under full load and check if output matches expected numbers
• Replace anything as needed
Check the Fuel Supply Regularly
Always double-check your fuel supply and ensure that it has adequate levels for operations. If the fuel has been contaminated with other substances, be sure to replace it as soon as possible. It depends on which liquids or particles your reservoir has been exposed to, but some can be corrosive to the insides of your machine. As a result, it may cause your piston pump to deteriorate from the inside out.
Don’t Troubleshoot Problems Yourself
If you’ve taken all the needed preventive measures and still aren’t content with the performance of your machine, ask for help from professionals. Your piston pump may need to be observed by a more trained eye. While you’re waiting for the scheduled appointment, however, make sure to stop using your device and halt all attempts of fixing it on your own. This is because you may be unconsciously making its condition worse.
Piston pumps work using a rod moved up and down in a cylindrical tube. This cylinder has a small hole in it that allows the liquid or gas to pass through it at the bottom of its cycle and then be pushed out of the top when at the top of its cycle. Furthermore, these machines can be used for many different purposes, including pumping water, oil, sewage, and other liquids.
