D Series - Powered By ORBIS™ Technology

A reliable solution for precise dosing, fluid circulation, or advanced measurements in industrial systems is the D Series Pumps by ARO, equipped with innovative ORBIS™ technology. These pumps meet the needs of modern manufacturing processes and OEM applications.

With advanced closed-loop speed control, a compact design, and up to 20,000 hours of reliable operation, our pumps set new industry standards. ORBIS™ technology ensures stable and precise performance under all conditions, regardless of load variations or system parameters, making them the perfect choice for companies that demand uncompromising quality and efficiency.

ORBIS Technology utilizes a closed-loop speed control system that achieves a set point for speed very quickly and holds this point independent of load which ensures fluid delivery will be consistent regardless of application and system variables.

Standard product supports four-wire and two-wire configurations. The four-wire configuration allows speed control of 0 to 5 volts from 800 to 3600 RPM, tach out for speed monitoring, reversing control, as well as fault-out and current-out. An alternate simplified two-wire configuration can easily replace a brushed motor in OEM applications. ARO's robust D Series platform has proven performance and long life of up to 20,000 hours. The pump is driven by a Neodymium magnet that delivers 85 mNm of torque to cover a wide range of applications. The compact footprint of ORBIS pump and motor allows it to integrate into almost any application. Static O-Ring seals are leak-free and make field repair with service packs simple. Also, optional integrated push-to-connect tube fittings reduces installation time by at least 50% and saves additional space compared to traditional ports.

 

Building on a vast knowledge of hydraulics, mechanics, and electronics comes proven D Series pumps powered by ORBIS Technology. ORBIS Technology enhanced drive solution offers an integrated brushless DC motor with closed-loop control delivering performance that satisfies a high variety of applications in a compact design with exceptional reliability and extended life. D Series external gear pumps are known for their seal-less construction and non-pulsing flow which makes them perfect for precise circulating, dosing, and metering applications.If the application requires a leak-free, compact, and technically advanced pump, ARO's D Series pumps with ORBIS Technology is the solution.
