The VOSS VT Series Servo Diaphragm Metering Pump is a high-capacity industrial dosing solution developed for high-throughput and heavy-duty continuous transfer applications, covering a flow range of 10–1500 L/h. It is designed for industrial processes requiring stable continuous dosing, bulk chemical transfer, and centralized liquid feeding control. Based on conventional large-flow metering pump technology, the VT Series features reinforced drive rigidity, improved transmission stability, and an enhanced pump head structure to ensure long-term performance in demanding process sections.
Product Overview
The VOSS VT Series Servo Diaphragm Metering Pump is a high-capacity industrial dosing solution developed for high-throughput and heavy-duty continuous transfer applications, covering a flow range of 10–1500 L/h. It is designed for industrial processes requiring stable continuous dosing, bulk chemical transfer, and centralized liquid feeding control. Based on conventional large-flow metering pump technology, the VT Series features reinforced drive rigidity, improved transmission stability, and an enhanced pump head structure to ensure long-term performance in demanding process sections.
The VT Series adopts a reinforced servo-driven architecture combined with heavy-duty diaphragm components, an optimized fluid path, and a high-strength pump head structure. This allows the pump to maintain stable output and low-pulsation transfer even at high flow rates. It is especially suitable for large reagent preparation systems, centralized dosing units, industrial chemical transfer systems, and critical continuous dosing applications.
As a high-throughput product family within the VOSS large-flow range, the VT Series focuses not only on transfer capacity, but also on system reliability, industrial adaptability, and extended maintenance cycles, helping customers achieve efficient, dependable, and sustainable liquid dosing performance in complex operating environments.
Designer Profile

Industrial Automation Engineer
Smart Dosing Systems
Oliver Bennett graduated from the University of Bristol with a background in Automation Engineering and has more than 15 years of experience in industrial automation equipment, smart dosing systems, and industrial communication control. He has long specialized in the automation integration of fluid control systems, with particular expertise in large dosing equipment, remote control systems, and intelligent operation solutions for industrial sites.
At VOSS, Oliver Bennett is responsible for the automation-oriented design philosophy and system architecture optimization of the VT Series high-throughput servo diaphragm metering pump. He believes that high-flow industrial equipment must deliver not only strong transfer capacity, but also system-level stability, automation compatibility, and long-term operational reliability. For this reason, the VT Series development places special emphasis on continuous heavy-duty operation, industrial system adaptability, and coordinated control capability within centralized dosing systems.
Design Philosophy
Design Philosophy
Oliver Bennett believes:
“The value of high-throughput industrial dosing equipment lies not only in larger flow output, but in its ability to operate continuously, stably, and reliably within automated systems.”
In the design of the VT Series, the following principles are emphasized:
Through these design principles, the VT Series is not only a high-throughput metering pump, but also a high-flow continuous transfer solution designed for modern industrial automation systems.
