Huanyu Oilless Diaphragm Vacuum Pump(HYD-V20) is a kind of dry vacuum pump, which is widely used in the area of the biological laboratory, metallurgy, light industry, food, and other industries. The dry pump is a high-vacuum pump that uses no oil or grease lubrication. It can be used for the vacuum of about 1.3×10−5 Pa to 10−1 Pa.
In the process of operation of this machine, the relative movement between the diaphragm and plate will cause the volume of the cavity to change. Inside the cavity, there is a flexible diaphragm with a certain tension. When the volume of the cavity decreases, the diaphragm will be stretched and thus increase its internal pressure. When the volume of the cavity increases, it will be compressed and reduce its internal pressure.

Though an oilless vacuum pump has no oil in the engine, the air compressor cylinder is made of aluminum alloy material with excellent heat dissipation performance. Therefore, when working, it can avoid high temperatures due to high pressure and prolong its service life. In addition, it also has advantages such as being lightweight and being easy to operate.
In addition to low noise, low power consumption, and energy-saving, the oilless vacuum pump has other advantages such as easy installation and good sealing performance, and so on. Based on the characteristics of this vacuum pump, it is mainly used in various fields such as scientific research experiments, medical treatment, and so on.
The product uses an oil-free diaphragm pump with excellent vacuum characteristics for negative pressure generation. The use of imported special rubber eliminates the need to add lubricating oil. It does not require regular maintenance and can be operated continuously for 24 hours without stopping operation.
Happybuy Air-Operated Double Diaphragm Pump is a double-action pump with a single cylinder and a double-acting piston.
Double-acting piston pumps are a type of positive displacement pump in which the piston can perform work in both directions. Double-acting piston pumps have two pistons, one on either side of a common cylinder, and two inlet and two outlet valves.
Double-acting piston pumps provide a large amount of suction lift and can deliver fluids to great heights (up to 200m vertical head).
JOANLAB Oilless Diaphragm Vacuum Pump is widely used in laboratories, including food, drug, beverage, and drinking water industry tests, suspended solids determination, and microanalysis of sample pretreatment, or solvent passivation; Compared with gravity flow, vacuum filtration can greatly reduce processing time and improve efficiency.
Vacuum gauge-Simple operation, stable performance, high accuracy of measurement, and quick response. Overload protection, over-temperature protection, short circuit protection, using more safety.
Oilless vacuum gauge exhaust port. Unique leather film design reduces wear and increases working life. It provides a clean vacuum environment and doesn't produce pollution to the system.
The high-quality non-slip suction cup makes the vacuum pump anti-slip and anti-shock in the process of use, improving work efficiency.
StonyLab Oil free Diaphragm Vacuum Pump is an oil-free vacuum pump that provides a reliable vacuum source for evaporation, distillation, solvent filtration, vacuum desiccation, solid-phase extraction, and other lab work.
The oil-free feature provides cleaner operation, eliminating the need to handle, change or monitor oil.
StonyLab Diaphragm Vacuum Pump offers the advantage of high vacuum without oil or any other liquid. It can run well in an environment with high moisture and high temperature since the pump relies on the metal plate and plastic diaphragm to generate suction force.
Happybuy Air-Operated Double Diaphragm Pump is a kind of advanced double diaphragm pump. It is used to transfer the liquid with a viscosity up to 1000cps.
The pump is made of good quality material and it has a double-acting seal that delivers better performance. It can be used to transport chemicals, water, and viscous liquids.
The pump is powered by air (90 psi) and it can be used in various applications below.
Diaphragm pumps are the most common pumps used in many industries because they are reliable, robust and easy to install. Here are some of the reasons why you should use diaphragm pumps.
Diaphragm pumps are cheap compared to other types of pumps. You can even buy them at prices that are lower than $300.
It is very easy to install diaphragm pumps because they do not require specialized tools. You can even fix them yourself if you can follow instructions properly.
The lifespan of diaphragm pumps is longer than other types of pumps. The duration may last up to 30 years depending on the application and quality of the pump.
Diaphragm pumps can deliver large quantities of fluids at high pressure levels. They can deliver up to 240 gallons per minute (gpm) or 1000 liters per hour (lph).
This is the vertical distance that the pump can lift liquid vertically.
This is the rate at which liquid can be pumped through the pump
The normal range is 20 psi (pounds per square inch) and above
Maximum allowable temperature
(Maximum allowable pressure at which it can be used)
This is very important as it will determine the flow rate and the maximum head that can be achieved
This is the amount of liquid that can be retained by the pump
This is a measure of how often a pump can be operated at a given capacity, i.e for a period of one hour, how much discharge can be achieved?
This is a measure of how much power is needed to operate a pump
This is a measure of how much head can be obtained from a given amount of power input
If yes, then there are many design considerations to take into account.
A: One of the main advantages is that diaphragm pumps are one of the most compact types of pump. Due to their small size, they can be easily mounted on a machine and in most cases, no adjustments will be needed to mount them. They are also very reliable and you can expect them to last for a long period of time with good care.
A: A diaphragm pump works with any type of liquid and its flow rate is quite flexible and can be adjusted with minimal effort.
A: The main disadvantage is that they require a lot of maintenance and care in order to last for a long time. Since they use rubber parts for moving parts, they need to be lubricated in order to work properly. If you do not lubricate them, then they will break down quickly.
A: A good quality diaphragm pump can last up to 10 years with proper care and maintenance.
A: As far as price is concerned, they can cost anywhere from $100 up to $5000 depending on the quality and brand.
Diaphragm pumps are easy to use and maintain. They are also very compact in size which makes them easy to mount on a machine without any problem. If you purchase a high quality diaphragm pump, then it will last for a long period of time without any problem.
