Auto Greasing

Reliable Solution for Rising Stem Valve Actuators

AUMA Actuators Limited supports the UK water industry with reliable electric actuator solutions. For rising stem valve applications, effective lubrication is essential to maintain performance, reduce wear, and extend asset life.

Auto greasing systems can help ensure consistent lubrication of the valve stem and stem nut, particularly in demanding or hard-to-access environments.

Optimised maintenance

Why Auto Greasing is Important for Valve Actuators

In rising stem, multi-turn applications, excess friction between stem and drive nut can increase required torque and degrade nut life.

Without proper lubrication, operators may experience:

Accelerated wear of valve components

Reduced operational efficiency

Higher risk of unplanned downtime

Inconsistent maintenance schedules

Over- or under-greasing

Reduced reliability in critical infrastructure

Key Benefits of Auto Greasing Systems

Extended Valve and Penstock Life

Consistent lubrication reduces wear on critical components such as the stem and thrust assembly.

Lower Operational Risk

Helps prevent failures caused by insufficient or inconsistent lubrication.

Reduced Maintenance Requirements

Minimises the need for frequent manual greasing, especially in remote or inaccessible locations.

Improved Actuation Performance

Supports stable torque output and smooth valve operation over time.

How Auto Greasing Systems Work

Auto greasing systems for rising stem valves are typically designed to:

Deliver grease at controlled intervals

Target the stem and stem nut interface

Operate independently of the actuator gearbox

Be configured based on duty cycle and environmental conditions

Applications in the Water and Wastewater Industry

Water treatment plants

Pumping stations

Reservoir and distribution networks

Remote or unmanned installations

Reducing Maintenance Costs and Downtime

By implementing auto greasing solutions, operators can:

Reduce site visits and manual intervention

Lower maintenance and labour costs

Improve asset uptime and availability

Support planned, predictive maintenance strategies

Engineered for Compatibility with AUMA Actuators

Actuators from AUMA Riester GmbH & Co. KG are designed with robust, sealed gear systems and long service intervals. Auto greasing solutions are application-specific and must be correctly selected to complement the actuator and valve configuration.
