Vertical Legacy, Global Reach
Vertical Hollow Shaft Motors for Deep Well Pumping

Vertical Hollow Shaft (VHS) motors are the driving force behind deep well pumps—especially in regions with demanding irrigation and water supply infrastructure. While commonly used in the United States and Middle East, they are less widespread in Europe. However, Greece holds an exception.

In the 1960s, a pioneering Greek pump factory helped introduce VHS technology to the local market. Valiadis S.A. was a key supplier in that effort, helping establish these motors as a viable and durable solution for deep pumping applications.

Fast forward to today, and we’re proud to continue that legacy—combining historical know-how with modern performance standards. Most recently, we delivered two powerful VHS motors, each rated at:

• 600 HP

• 4 poles

• With a water-cooled upper oil-bearing chamber for enhanced reliability

Designed for vertical mounting and hollow shaft coupling, these motors are built for direct connection to pump lineshafts, ensuring smooth, efficient power transmission with minimal footprint.

Applications:

• Deep well pumping

• Agricultural irrigation systems

• Water supply infrastructure in arid regions

Built for depth. Trusted for decades.
