Options We Can Offer

Modular Diaphragm Pump Platform

TOPSFLO miniature diaphragm pumps combine modular design, advanced material options, precision manufacturing, and intelligent control to deliver reliable pumping solutions tailored to different application requirements.
01. Flexible Modular Design
One Platform. Multiple Configurations.

TOPSFLO adopts a unique modular architecture that provides exceptional flexibility in pump design and configuration.
Key components—including BLDC motors, eccentrics, pump heads, diaphragms, valves, materials, and connectors—can be flexibly combined and optimized according to specific application requirements.
This modular approach allows engineers to fine-tune the pump for flow, pressure, vacuum, noise, power consumption, service life, and media compatibility, while maintaining a compact and highly integrated design.
From component selection to overall pump performance, TOPSFLO provides the flexibility to develop the right configuration for each application.
Flexible Design. Modular Architecture. Application-Specific Performance
02. Advanced Material Options
The Right Material for the Right Medium

Material compatibility is critical to pump reliability and service life. TOPSFLO offers PTFE, FKM, EPDM, and FFKM material options for different fluid-contact components.
Different materials provide different levels of chemical resistance, temperature resistance, sealing performance, and durability, allowing the diaphragm, valves, and other wetted components to be matched to the pumped medium.
This flexible material system helps TOPSFLO deliver reliable performance across a wide range of fluids and demanding operating conditions.
03. Configurable Diaphragm & Valve System

The diaphragm and valve system directly determines the pumping characteristics of a miniature diaphragm pump.
TOPSFLO supports different diaphragm materials, diaphragm thicknesses, and valve structures to optimize flow, pressure, vacuum, pulsation, chemical compatibility, and operating life for specific applications.
The diaphragm also isolates the compression chamber from the drive mechanism, providing reliable separation between the pumped medium and the mechanical drive system.
04. Optimized Eccentric & Pumping Chamber

Different eccentric configurations and pumping chamber volumes can be selected to achieve different displacement and flow characteristics.
Combined with the diaphragm and valve system, the eccentric mechanism can be optimized around the actual operating point to achieve the desired balance of flow, pressure, speed, power consumption, and service life.
05. BLDC Motor & Intelligent Control

TOPSFLO diaphragm pumps can be equipped with high-efficiency BLDC motors for stable, responsive, and controllable operation.
Multiple control and feedback options are available, including PWM speed control, 0–5 V analog control, and FG speed feedback, making the pumps easy to integrate into intelligent equipment and automated systems.
06. Precision Manufacturing
Engineered for Precision. Proven in the Field.

Advanced design is only the beginning. Consistent manufacturing turns a high-performance pump design into a reliable product.
With a 16,000 m² self-owned manufacturing facility, TOPSFLO combines precision manufacturing, automated production, strict process control, and comprehensive testing to ensure consistent quality and reliable performance.
With extensive experience in OEM/ODM projects and long-term cooperation with leading global companies and Fortune 500 enterprises, TOPSFLO has developed proven capabilities in product development, process validation, quality control, and mass production.
From prototype to production, TOPSFLO provides the manufacturing expertise and quality assurance required for demanding industrial applications.
07. Flexible Fluidic Connections

TOPSFLO offers multiple fluidic connection options to simplify integration with different tubing and piping systems, including hose connectors, push-in connectors, internal-thread connectors, and customized inlet/outlet configurations.
Connector options can be matched with the pump head and fluid-contact materials to meet specific system requirements.
