The normal operation of hydraulic equipment is determined by various internal processes occurring within the pump itself. However, if issues arise, how can they be recognized in order to take timely measures?

Let’s take a detailed look at the key causes of failures in gear pumps and how to identify them.

1. Lack of fluid delivery or insufficient fluid flow

This can be caused by a faulty drive or incorrect fluid flow direction. For example, according to the technical passport of the pump, the fluid flow should be right-handed, but the pump is used for left-handed or reversible movement. Leakage of fluid or exceeding the permissible contamination level, as specified in the technical passport, can also lead to these consequences.

2. Formation of foam inside the pump equipment

This indicates a seal failure, leading to air entering the system. If the valve in the distributor (a device for distributing the flow of liquid, steam, or gas in steam, hydraulic, and pneumatic machines) becomes clogged, or if the relief valve is incorrectly adjusted, the equipment will not provide the required pressure. Additionally, both of these reasons can contribute to overheating of the unit.

3. Vibration or unusual sounds from the pump housing

Check the drive for wear or pipelines for possible blockages due to increased viscosity of the fluid inside the pump. If the drive is excessively worn, the hydraulic equipment will shut down.

Maintain the efficient operation of your equipment by monitoring these key points and let your hydraulic pumps work at full capacity without breakdowns!
