Common Concerns and Questions About Gorman Pumps

Gorman pumps are widely used in wastewater treatment lift stations industrial dewatering and other heavy duty applications. Operators and technicians often face practical issues related to performance maintenance troubleshooting and long term reliability. Below we explore the five questions that come up most frequently in discussions among pump professionals and users.

Why Do Gorman Pumps Lose Prime or Go Air Bound

One of the most common operational challenges with Gorman pumps is losing prime or becoming air bound during service. When a pump gets air trapped in the suction line or casing it can no longer draw water effectively and stops pumping even though the impeller still turns. This often happens because of a suction line leak a faulty fill plate gasket or improper flap valve seating. Ensuring all gasket surfaces are clean tight and free of air leaks along with proper suction lift setup will help maintain prime. Careful sealing and regular inspection of suction components greatly reduce time spent troubleshooting this issue. 

What Causes Frequent Blockages and Clogging in Gorman Pumps

Many operators report frequent blockages especially in wastewater or trash pumping applications. Large solids debris stringy material and even unexpected objects flowing into the suction can jam the impeller or clog the pump casing. In heavy duty setups installing screens or prefilters upstream can reduce the risk of large debris entry. Choosing the right impeller type that handles solids and maintaining a clean intake environment also lowers blockage occurrences. Preventive planning around expected solids types and sizes makes the pump more reliable for continuous operation under tough conditions. 

How Do I Maintain a Gorman Pump to Extend Service Life

Maintenance practices directly impact the performance and life of any pump including Gorman models. Operators often want to know which components require regular inspection and when to replace them before failure occurs. Critical parts like mechanical seals worn bearings impellers and suction check valves should be checked routinely. Keeping an inventory of spare wear parts reduces downtime and supports quick repairs. Regular lubrication cleaning of strainers and verification of correct clearances helps maintain efficiency and prevents small issues from becoming major breakdowns. A structured maintenance program is one of the best investments to ensure reliable pump operation. 

How Do Gorman Pumps Compare in Reliability and Support

Another frequent topic among users is how Gorman pumps perform compared to alternatives and what support to expect from distributors. In many installations these pumps have a reputation for rugged construction and robust performance when applied correctly. Some operators say they are reliable and easy to work on while others emphasize the importance of local service responsiveness and parts availability. Familiarity with the technology and solid support from trusted service partners enhances uptime and reduces frustration during repairs. Choosing the right local representative helps ensure ongoing support when the system is in service. 

What Are Best Practices for Installing and Aligning Gorman Pumps

Proper installation plays a crucial role in how well a Gorman pump performs. Users frequently ask about tips to avoid issues like vibration misalignment excessive wear or reduced efficiency. Ensuring that the pump is mounted on a solid level base with secure anchors helps reduce vibration and stress on the shaft and bearings. Checking alignment between the drive and pump components prevents early wear of seals and moving parts. Correct piping design that minimizes unnecessary bends and maintains smooth flow into the pump suction reduces turbulence and performance loss. Attention to detail during installation sets the foundation for long term operational success and fewer service interruptions.
