Top 2 Small Negative Pressure Pump Application

Table of Contents

A micro negative pressure pump is simply an air pump that can be used in gas sampling, gas analysis, medical treatment, and scientific research. They are reliable, stable, and lightweight.

Small negative pressure pumps combine the efficiency and operational features of positive displacement pumps with compact structural materials. Their driving force is created by the difference in pressure between the two sides of the chamber wall – the atmospheric pressure and the extremely low pressure within the vacuum chamber.

The following paragraphs will delve into the applications of the top two small negative pressure pumps, including a pump for negative pressure wound therapies and pumps for negative pressure beauty machine. Also, we will take a look at their application advantages and work principles.

Pumps For (NPWT) Negative Pressure Wound Therapy

These are pumps that are used in negative pressure wound therapy. They help in drawing out fluid and infections from wounds, allowing them to heal more quickly. A particular dressing performance is done to the area, and a light vacuum pump is attached.

The healing process is facilitated by boosting the blood flow to the area around the wound. The vacuum can be administered intermittently or continuously, based on the type of wound and the therapy plan. Also, different wound therapy pumps with varying capacities and pressures are used to match the type of wound.

When Are Negative Pressure Therapy Pumps Used?

The negative therapy pumps are used in;

  • Acute and chronic traumatic and surgical wounds
  • An open chronic wound like diabetic foot ulcers and venous stasis ulcers
  • Dehisced and sub-acute wounds of partial-thickness burns
  • An adjunct to skin grafts surgeries and closed surgical incisions

What Is A Negative Pressure Wound Therapy (NPWT)?

This is a medical treatment technique that exerts sub-atmospheric pressure to the surface of a wound to improve wound healing while shortening treatment periods and minimizing infection risks.

Negative pressure wound therapy is a common therapeutic modality for post-operative, chronic, and acute wounds of varying sizes and geometry, such as ulcers and second-and third-degree burns.

What Are The Uses Of A Negative Pressure Wound Therapy Pump?

Removal of fluid

Removing fluid relieves compression on the vascular system and enhances blood circulation, both of which promote wound healing. Also, excess fluid buildup reduces the likelihood of a speedy recovery.

Suction-assisted wound shrinkage

Pressure transmission over the injured surface with varying elasticity causes tissue stretching and, eventually, wound contraction. The pressure transmission is done continuously for quick healing.

Wound environment stabilization

With a negative pressure pump, the treatment technique manages the wound environment and protects the surrounding skin. Wound infection prevention is one of the main benefits of the cellophane cover utilized in the administration of NPWT.

Other uses of negative pressure wound therapy pumps include;

  • Reducing wound swelling
  • Increasing blood flow to the surrounding skin
  • Reducing wound infections
  • Keeping the wound warm and moist

How Does Negative Pressure Wound Therapy Pump Work?

The technique involves tubing, a special dressing, and a negative pressure device.

  • For proper wound care, layers of foam dressing are first applied to the shape of the wound and then covered with a film.
  • Tubing attached to the opening in the film then connects to a vacuum pump and a canister that collects fluid. The vacuum pump can be configured to run continuously or to start and stop periodically.
  • The vacuum pump is used to remove fluids and infections from the wound. This helps in drawing together the wound’s edges. It also promotes the creation of new tissue, which helps in wound healing.
  • Saline and antibiotics can be injected into the surrounding skin if necessary for treating wounds. The clinical evaluation is efficient with no canister system.

Negative Pressure Wound Therapy Pump (NPWT) Benefits

Key NPWT Pump benefits include;

  • A negative pressure wound therapy pump can run continuously with a negative pressure of 80mmHg (+/-20mmHg) applied to the wound.
  • Low sound and vibration levels are used to improve patient comfort and for proper wound care.
  • The design is compact and lightweight to promote patient movement.
  • A wide selection of products is designed for chronic, acute, or single-use purposes.
  • They are designed with a soft port to reduce the possibility of pressure damage. They are canister free.
  • The setup saves energy and extends battery life. It can work for a very long time before the pump life ends or replace batteries.

How To Choose The Right Negative Pressure Wound Therapy Pump For Your Patient

Healthcare providers sometimes find it challenging to choose the right wound therapy pump that matches the condition of the patient. The following are the main factors to consider when selecting a negative pressure therapy pump for your patient;

Negative pressure settings

Most systems provide pressures ranging from -20mmHg to -200mmHg. Some have many options, while others just have one. Furthermore, some systems enable negative pressure supply regulation. The healthcare providers should go for devices that maintain a greater negative pressure in the ‘off’ or ‘low’ or ‘off’ state to maintain exudate evacuation and keep the wound bed.

Full indicator for use

Always ensure that the therapy device is working correctly. Some devices like pico single use negative pumps are designed exclusively for a single function, such as managing surgical incisions or very mildly exuding lesions. Sometimes a pico pump can have all the indicators, including all possible wound types and etiology.

Dressing interface

Some devices include a configurable dressing medium to enable adaptability to different wounds in terms of depth, exudate, and dressing size. A pico pump sometimes cannot be customizable and is only suggested for use in some patients. The majority of dressing mediums are made up of gauze and hydrocolloids.

Exudate management

Some devices have several canister capacities to effectively manage wounds with moderate to severe exudate. Canisters can be replaced or housed within a disposable NPWT unit. Other NPWT systems collect exudate from within the dressing system.

Power source

Powered NPWT devices can run on disposable batteries, rechargeable batteries, or electricity from an outlet. Because of the inclusion of an electrical pump mechanism, these devices can be heavier, bigger, and noisier. Non-powered NPWT systems employ mechanical energy from a spring mechanism to lower air density within an enclosed area in a regulated way by providing a continuous vacuum for exudate. Also, they will work for a very long time before their wear time.

Pumps For Negative Pressure Beauty Machine

These are pumps that are widely used in cosmetic industries and beauty machines for moving lotions, creams, glosses, oils, and gels that are used in beauty equipment. They are suitable for mixing and pumping from totes, containers, and barrels, as well as bulk transmission and batching.

What Are The Applications Of Negative Pressure Pumps For Beauty Machines?

The main use of negative pressure pumps for beauty machines is dispensing body care products. They help in the packing of lotions, facial creams, and skincare products in either a basic tube or a convenient dispenser. Other applications include;

  • Batch production of hygienic or sensitive materials
  • Transferring raw products into mixing vessels. They move materials at a rate of up to 300,000 Cps and pump particles up to 25mm cube
  • Dosing fragrances
  • Chemical dosing
  • Adding alcohols
  • Color and gloss metering

What are the Benefits Of A Negative Pressure Beauty Machine Pump?

The main benefits of negative pressure pumps for beauty machines include;

Minimal wastage – Negative pressure beauty machine pumps are designed to ensure that 99% of the barrel’s contents are drained and with no air leaks.

Reversible – They allow for product recovery from inside hoses or lengthy delivery lines.

Batching – With a negative pressure beauty, machine pump adjustments for different viscosities are made automatically. It allows for the process of repeatedly batching uniform amounts for continuous batching into recipes or vessel filling without using scales.

Viscosity – The pump can handle different fluids with different viscosities.

Hygienic – It has polished internal parts. The beauty machine pump can also be cleaned simply for washing and disinfecting.

How To Choose A High-Quality Pump For Negative Pressure Beauty Machine?

Select a negative pressure pump with low noise and good batch consistency

The buzzing sound of beauty machines during operation has a direct impact on the satisfaction of customers. A low-noise beauty machine can aid in the silent operation of beauty equipment and the creation of a pleasant experience environment for customers.

Select a negative pressure beauty machine device that is maintenance-free and can run for a long time 

Poor quality beauty pumps have low dependability and are susceptible to fracture of the cavity and deformation of the pump head when used for a long period of time, resulting in high maintenance expenses for beauty equipment. Go for pumps that are highly reliable and have a lifetime maintenance-free warranty.

Select a beauty machine pump with complete certification for product and material

Beauty equipment is utilized in a specific context and belongs to the beauty businesses. Always supervise the choice of pump parts closely to enhance consumer safety. The building materials should meet quality and safety standards such as NSF and WRAS.


With the above points, you can now easily choose the right pump for negative pressure wound therapy and beauty machines. Negative therapy pumps are useful in accelerating wound healing, whereas beauty machine pumps are used for transferring beauty products. This brief guide has also highlighted the benefits of the negative pumps as well as the main factors to consider when buying your negative pressure pump.
