Product Overview

KVP8 Plus is a miniature diaphragm air pump developed for negative pressure and gas transmission applications. It uses a diaphragm structure to generate vacuum pressure and airflow without direct oil lubrication, making it suitable for compact pneumatic systems that require clean air transmission, stable suction, and long-term operation.

The product is available in different configurations to meet different application needs.

For applications requiring higher airflow, the parallel configuration provides strong gas transmission capacity. KVP8 Plus-KK/KJ offers a flow rate of ≥10 L/min, while KVP8 Plus-KD/KB offers a flow rate of ≥11 L/min. The maximum vacuum for the parallel configuration can reach ≤-0.070 MPa.

For applications requiring deeper vacuum, the serial configuration provides stronger negative pressure performance. KVP8 Plus-KK/KJ-S offers a flow rate of ≥6.3 L/min, while KVP8 Plus-KD/KB-S offers a flow rate of ≥6.6 L/min. The maximum vacuum for the serial configuration can reach ≤-0.090 MPa.

This makes KVP8 Plus suitable for both high-flow suction systems and high-vacuum negative pressure systems.

Key Features of KVP8 Plus

High Vacuum and Large Flow Options

KVP8 Plus supports both serial and parallel pneumatic configurations.

The serial configuration is suitable for systems that require deeper vacuum and stronger suction performance. With a maximum vacuum of ≤-0.090 MPa, it can be used in negative pressure adsorption, vacuum suction, and compact pneumatic control applications.

The parallel configuration is suitable for systems that require higher airflow and faster gas extraction. With a flow rate up to ≥11 L/min and vacuum up to ≤-0.070 MPa, it helps equipment achieve faster response and more efficient gas transmission.

This configuration flexibility allows OEM customers to select the proper pump structure according to system requirements, such as vacuum depth, airflow demand, response speed, tubing length, and internal chamber volume.

12V / 24V Voltage Options

KVP8 Plus supports both DC12V and DC24V power platforms.

The KK and KD versions are DC12V configurations, while the KJ and KB versions are DC24V configurations. This allows the pump to match different equipment power systems without requiring major changes to the control platform.

The rated power of KVP8 Plus is 9W, making it suitable for compact devices where energy consumption and heat generation need to be controlled.

Brushed and Brushless Motor Options

KVP8 Plus provides both brushed and brushless motor versions.

The KK and KJ versions use DC brushed motors. These versions are suitable for applications with moderate lifetime requirements and cost-sensitive projects.

The KD and KB versions use DC brushless motors. The brushless versions have a product lifetime of ≥6000 hours, making them more suitable for equipment platforms that require longer service life, frequent start-stop operation, and higher reliability.

For medical beauty equipment, gas detection systems, smart home appliances, and industrial automation devices, the brushless version is often the preferred choice when long-term reliability is a key requirement.

Compact Structure for OEM Integration

KVP8 Plus is designed with a compact structure, helping equipment manufacturers integrate the pump into limited internal spaces.

Its small pump body, lightweight design, and multiple mounting points make it suitable for embedded pneumatic modules. It can be installed inside medical beauty equipment, gas detection instruments, freshness preservation systems, vacuum suction modules, and other compact devices.

For OEM customers, the compact design helps reduce structural layout pressure and supports more flexible product design.

Stable Operation and Low Noise Design

According to the product manual, the noise level is ≤74 dB for the standard configuration and ≤72 dB for the serial configuration under specified test conditions.

In actual equipment applications, the final noise performance is related to the installation structure, housing design, tubing layout, vibration isolation, and airflow path. By using soft tubing, damping materials, optimized air channels, and acoustic enclosure design, equipment manufacturers can further improve the overall acoustic performance of the system.

KVP8 Plus is suitable for applications where stable air transmission, compact installation, and controlled operating noise are required.

Reliable Materials for Gas Transmission

The main wetted and structural materials of KVP8 Plus include PA for the pump head and pump body, EPDM for the diaphragm and valve plate, and metal for the eccentric wheel.

This material combination is suitable for general air and gas transmission applications. For special gases, humid gas, volatile components, or contaminated air, application testing and chemical compatibility evaluation are recommended before mass production.

To improve system reliability, a front-end filter is recommended when the pump is used in environments with dust, particles, moisture, or possible contamination.

CE and RoHS Compliance

KVP8 Plus complies with CE and RoHS requirements, supporting OEM customers in medical beauty equipment, gas detection instruments, smart home appliances, and export-oriented projects.

For equipment manufacturers, certified components help simplify project evaluation and improve product compliance readiness.

Typical Applications

KVP8 Plus can be used in a wide range of negative pressure and gas transmission systems.

In medical beauty equipment, it can provide stable negative pressure for suction modules, skin adsorption systems, and vacuum-assisted handpieces.

In gas detection instruments, it can be used as a sampling pump to drive gas through sensors, filters, or detection chambers.

In medical and rehabilitation equipment, it can support vacuum suction, pneumatic control, and negative pressure modules.

In industrial automation, it can be used for vacuum adsorption, suction cups, and small pneumatic systems.

In smart home appliances, it can support air management modules, freshness preservation systems, and compact gas circulation functions.

In environmental monitoring equipment, it can provide gas sampling and air transmission support for detection systems.

Application Value for Equipment Manufacturers

For OEM equipment manufacturers, KVP8 Plus provides a combination of performance, reliability, and integration flexibility.

Its high vacuum capability helps systems achieve stable suction and negative pressure control.

Its large airflow options help improve gas extraction efficiency and shorten response time.

Its brushless motor versions provide longer service life for equipment requiring frequent start-stop operation.

Its compact structure supports installation in space-limited devices.

Its 12V/24V compatibility makes it easier to match different power platforms.

Its CE and RoHS compliance supports international equipment development and export projects.

With these advantages, KVP8 Plus can help manufacturers build more compact, reliable, and efficient negative pressure systems.

Selection Guidance

For applications that require deeper vacuum and stronger suction performance, the serial configuration is recommended.

For applications that require higher airflow and faster gas extraction, the parallel configuration is recommended.

For applications that require longer lifetime and higher reliability, the brushless motor version is recommended.

For applications involving moisture, particles, or contaminated gas, front-end filtration and system-level protection should be considered.

For applications with special gases or chemical exposure, compatibility testing should be performed before final selection.
