product description

KP48-V High-Flow Diaphragm Air Pump

The KP48-V is a compact diaphragm air pump designed for gas transfer, vacuum generation and pressure supply in OEM equipment. Its outer-rotor brushless DC motor supports adjustable-speed operation, while the embedded motor structure helps the pump operate in demanding environments such as dusty or humid equipment interiors.


Key Features

  • Peak free-flow rate of ≥12 L/min

  • Effective flow rate of ≥6 L/min

  • Vacuum performance of ≤-0.075 MPa

  • Positive pressure of ≥0.2 MPa

  • Outer-rotor brushless DC motor

  • 12 V and 24 V configurations

  • PWM and 0–5 V speed control

  • FG speed feedback

  • Suitable for dry-running operation

  • Standard EPDM diaphragm with optional FKM or HNBR configurations

  • G1/8 female ports with standard 8 mm push-in fittings


Typical Applications

  • Gas detection and environmental monitoring equipment

  • Vacuum systems in household appliances

  • Waste evacuation in microplate washers

  • Industrial vacuum suction cups

  • Gas sampling and transfer equipment

  • Automated pressure and vacuum systems


Technical Specifications

Item Specification
Pump type Diaphragm air pump
Peak free-flow rate ≥12 L/min
Effective flow rate ≥6 L/min
Vacuum ≤-0.075 MPa
Positive pressure ≥0.2 MPa
Rated voltage 12/24 V DC
Motor type Brushless DC motor
Power ≤20 W
Control On/Off, PWM or 0–5 V speed control
Speed feedback FG signal, 1 pulse per revolution
Reference noise ≤72 dB at 50 cm
Port G1/8 female thread
Standard connector 8 mm push-in fitting
Product life ≥10,000 h for the standard configuration
Weight Approx. 420 g
Operating temperature 0–50°C

Material Options

Component Standard Configuration Optional Configurations
Pump head PPS PPS
Pump body PPA PPA
Diaphragm EPDM FKM or HNBR
Valve EPDM FKM or HNBR
Seal FKM FKM

Material selection should be based on the gas composition, temperature, humidity and chemical compatibility requirements of the application.


Speed Control

The KP48-V supports two speed-control methods:

  • PWM control: 10–30 kHz, 5 V amplitude; 0–10% duty cycle stops the motor, while 11–100% provides speed adjustment.

  • Analog voltage control: 0–5 V input; 0–0.5 V stops the motor, while 0.6–4.5 V provides speed adjustment.

The FG output provides one pulse per motor revolution for speed monitoring.

Performance data were measured using air at standard atmospheric pressure and 25°C, without inlet or outlet load. Actual flow, pressure, vacuum, noise and service life may vary with system resistance, environmental conditions, gas properties and duty cycle. Application testing is recommended before final OEM integration.
