Kiesel VAR55/1 Adjusting Shaft for Handwheel (P4 Variator)

Adjusting shaft for handwheel for Kiesel VAR55/1 pumps. A precision replacement component fitted with a P4 mechanical variator. 

It connects the external handwheel to the internal variable speed mechanism, allowing accurate control of pump speed, flow rate, and pressure—critical for wine transfer, must handling, and cellar operations.

Built for durability in winery environments, this shaft ensures smooth adjustment of the variator system without backlash or binding. It is a direct-fit replacement, making it ideal for maintenance, refurbishment, or restoring performance to worn or seized assemblies.

Installation & Maintenance

• Install as a direct replacement within the handwheel/variator assembly
• Ensure proper alignment with the internal variator mechanism
• Lubricate regularly to prevent seizing
• Do not force the handwheel—excessive torque can damage the shaft or variator
