4 Types Of Diaphragm Liquid Pumps

The need for a diaphragm pump is crucial to healthcare. It works by moving in response to the pressure difference between the two sides of the membrane, which leads to the movement of the piston.

The most common diaphragm liquid pump in use today is called a peristaltic liquid pump. This type of pump uses an accordion-shaped rubber or silicone tube that squeezes around a central rod to push fluid through it.

While there are branded pumps, like KNF diaphragm pumps, each can be categorized into major pump categories. This post lists common types of diaphragm pumps in healthcare.

What Is A Diaphragm Liquid Pump?

A diaphragm pump is a device that is placed inside the abdomen and used to drain excess fluid from the body. It's a type of peritoneal dialysis.

The pump opens and closes, creating pressure in the abdominal cavity, which pushes the fluid into a tube that leads to a catheter. The diaphragm pump is inserted through an incision in the abdomen, near the navel.

The diaphragm liquid pump is used as an alternative to hemodialysis for people with kidney failure who aren’t eligible for or don’t want peritoneal dialysis (PD).

How Diaphragm Liquid Pumps Work To Deliver Fluids And Medications

Diaphragm pumps are a type of external pump used to deliver fluids and medications.

A diaphragm pump is a small, battery-operated device that uses a thin rubber membrane or diaphragm to create suction to move fluid through the tube and into the body. The pump has a small tube attached to it that goes into the body and connects either to an implanted catheter or directly into the bladder.

The diaphragm will flex as air is pulled in through the tube, and this will create suction on the other side of the membrane. By creating suction, it pulls fluid from the inside to a bag or container outside of your body.

Types Of Diaphragm Liquid Pump

Most diaphragm liquid pumps are branded and owned by businesses. So, to purchase any of them would require you to read reviews. Nevertheless, branded or not, diaphragm liquids are generally of the following types:

1. Pressurized Diaphragm Liquid Pumps

A pressurized diaphragm pump is a positive displacement pump that moves liquid by repeatedly flexing a strong, thin, flexible diaphragm.

The pump consists of an inlet port, an outlet port, and a flexible diaphragm. The inlet port delivers the liquid to be pumped to the chamber on one side of the diaphragm. The outlet port leads away from this chamber to where it will be used.

As the inlet pressure increases, it pushes on the other side of the diaphragm, compressing it and pushing fluid out through the outlet port. When this pressure is released, it causes a return stroke that draws more liquid into the chamber on one side of the diaphragm.

2. Disposable Diaphragm Liquid Pumps

The disposable diaphragm liquid pump is a great accessory to have in your tool kit. It's designed to regulate the pressure of the liquid that passes through it.

The disposable diaphragm pump is used in many industries, such as food and beverage, chemical, pharmaceutical, and environmental engineering. This accessory can be used to regulate pressure in a variety of situations.

3. Manual Diaphragm Liquid Pumps

The manual diaphragm liquid pump is a mechanical device that has been in use for over 100 years. It's a simple mechanism that works on the principle of air pressure. The pump consists of two chambers, one containing the liquid to be pumped and the other containing a vacuum created by an external vacuum pump.

The process starts with the user pressing down on the top chamber, which causes it to collapse and draw in air from the outside through a valve. This creates a vacuum in the top chamber, causing atmospheric pressure to force liquid into it from below.

The user then removes their hand and allows atmospheric pressure to push down on top of it again, which forces any remaining liquid out of the bottom chamber back into its container.

4. Electric Diaphragm Liquid Pumps

An electric diaphragm vacuum pump is a device that produces a vacuum by drawing air out of a chamber. It can be used as an alternative to pneumatic pumps.

This pump is a device for pumping fluid using air pressure. The pump consists of a cylindrical metal case with the inlet and outlet on the same side. The inlet is connected to a tube that’s closed at one end and open at the other. The piston moves inside the cylinder, applying pressure to the liquid through the tube.

Conclusion

Diaphragm pumps play a significant role in healthcare. They help deliver and drain excess fluids. While there are several types of pumps you can use, the common ones have been detailed and explained above.
