Why Choose the 7102 Miniature Diaphragm Pump?

This model is built for equipment designers who need compact size, stable fluid control, material compatibility, and reliable OEM integration.

Double-Head Air Pump Design

Double-head structure supports stable gas transfer and vacuum generation in compact equipment.

High Gas Flow

8 L/min gas flow helps support faster air handling in medical, laboratory, and analytical systems.

Vacuum Capability

Vacuum ≤ -70 kPa supports suction and negative pressure applications.

Long Brushless Motor Life

>10,000-hour brushless motor service life helps reduce maintenance frequency.

12 V / 24 V Options

Voltage options support integration into different OEM system architectures.

Compact and Reliable

Designed for low-maintenance gas transfer in space-limited instruments.

Typical Applications

Air transfer in medical devices
Vacuum generation in laboratory instruments
Analytical equipment air handling
Environmental monitoring systems
Compact OEM pneumatic modules
Suction and negative pressure systems

Material and Medium Compatibility

Designed for gas transfer and vacuum applications
PP pump head with EPDM diaphragm
4 mm inner diameter silicone hose connector
Not intended for liquid transfer unless validated separately
Confirm pressure, duty cycle, and gas conditions before final selection

Model Selection Notes

Choose the 7102 when your application needs higher gas flow and vacuum generation. If your system needs single-head gas transfer with lower flow, compare it with the 7101.
