NOVADOS Pump Family

Versatile Combination of Diaphragm and Plunger Pumps

The NOVADOS Family comprises leak-free diaphragm pumps and plunger pumps. Nearly all gear sizes in the NOVADOS series can be combined to achieve specific flow rate and pressure requirements.

Compact Pumping Solutions for Industrial Applications

Challenges with Traditional Duplex Pump Heads

In industries such as oil & gas, chemical processing, and synthetic production, multiple pumps are often required for optimal performance. While duplex pump heads have traditionally been used, they can compromise space, weight, and efficiency.

Advanced Flow Control Solutions

The ARIS ExTensor and Tensor TS Flow Control Actuators are engineered for exceptional durability, aligning with the lifespan of Bran+Luebbe NOVADOS Series pumps. These adaptable flow control solutions enable precision adjustments in under a second, streamline onsite commissioning, and integrate seamlessly with existing process control systems for remote operation. The ARIS ExTensor’s robust design ensures reliable performance in harsh and explosive environments, enhancing plant efficiency and conserving resources.

These actuators are multi-turn rotary devices connected to the pump’s stroke length adjustment unit, modulating the stroke length and thus the flow rate of the pump. Controlled by a standard electrical signal (e.g., 4-20mA), the actuator adjusts the stroke to the desired position between 0% and 100% of the maximum stroke length.

Features:

Universal Actuator: One actuator type for H1-H6 NOVADOS Series pumps.
Reduced Commissioning Time: Simple and fast installation and programming
Remote Control Connectivity: Integrates with your existing process control systems for remote stroke adjustment capability.
Built for Continuous 24/7 Operations: S1 Operating Mode
ATEX Certification: The ARIS ExTensor is certified for Ex-Zone IIC*
