Its integrated gas ballast provides low ultimate pressure and high water vapor tolerance, resulting in excellent high vacuum performance. The TRIVAC B pump is quiet and vibration-free, contributing to the noise level in the operating environment. Its proven robust design, low heat loss, and air cooling make the TRIVAC B pump portable and compact.

Product Description

Product Overview

The Leybold TRIVAC D 16 B is a high-performance two-stage, oil-sealed rotary vane vacuum pump designed for stable and superior operation. It utilizes the rotary vane principle with oil injection into the pump chamber to ensure perfect sealing, continuous lubrication, and efficient cooling during operation.
Rugged & Durable The internal body is constructed from individual components without conventional seals, marked for precise reassembly. This design ensures exceptional durability and extended operating lifecycles.
Anti-Backflow System Equipped with a hydraulically controlled anti-backflow valve at the air inlet. It closes instantly when the pump stops, preventing vacuum chamber pressure buildup and oil contamination.
Optimized Cooling Features an integrated ducted cooling system with an additional motor-driven fan, maintaining constant temperatures and providing high water vapor tolerance.
Low Noise Design Intelligent vibration reduction and a flexible coupling between the motor and pump unit eliminate surface noise, ensuring a quiet working environment.
Continuous Operation An integrated oil pump guarantees lubrication at any inlet pressure, allowing the device to run safely at 1000 mbar or even at minimum oil levels.
Wide Application Ideal for medical sterilization, metallurgy, heat treatment, automotive industries, refrigeration, and as a backing pump for high-vacuum systems.
