In demanding industrial and municipal applications, pump reliability is critical—especially when handling liquids containing solids or debris. Gorman-Rupp’s self-cleaning and self-priming solutions provide a combination of efficiency, safety, and ease of maintenance. In this article, we explain how this technology works, which systems Gorman-Rupp offers, and how to select the right solution for your installation.
What is the secret behind a solids handling pump and a self-cleaning pump system?
The principle explained
Pump and systems for waste water applications are designed to minimize clogging and sediment buildup by automatically discharging solids and debris as part of its normal operation.
At Gorman-Rupp, this includes two core approaches:
- Self-priming centrifugal pumps, which automatically remove air from the suction line and restart without manual priming.
- Integrated system solutions such as the SCS System® and ReliaSource® lift stations, which incorporate angled collection systems that continuously flush out sediment and floating solids.
How it differs from standard pumps
Traditional wastewater or process pumps often experience clogging or performance loss due to fibrous or heavy solids. Gorman-Rupp’s designs minimize these risks through advanced hydraulic geometry, solids-handling impellers, and above-ground configurations that simplify inspection and servicing.
Why choose Gorman-Rupp’s self-cleaning solutions?
1. Less maintenance, more uptime
Gorman-Rupp’s self-priming pumps are engineered for dependable performance with minimal manual cleaning. The automatic priming function and solids-handling design drastically reduce downtime.
2. Proven reliability
Systems such as the Super T® and Ultra V Series® handle larger solids than conventional pumps, making them ideal for heavy-duty industrial and municipal applications.
3. Safer, easier installation
Most Gorman-Rupp pumps can be installed above ground—only the suction line enters the liquid. This eliminates confined-space entry and makes servicing safer and faster.
4. Complete engineered systems
Beyond standalone pumps, Gorman-Rupp provides turnkey pumping stations like the SCS System® and ReliaSource®, which combine self-cleaning and self-priming performance in fully integrated packages.
Gorman-Rupp technologies where self-cleaning is key
Self-priming centrifugal pumps
Gorman-Rupp’s Super T Series®, Super U Series®, and Ultra V Series® are proven for solids-handling and self-priming efficiency. These units automatically re-prime after brief interruptions and allow service from ground level.
System solutions with automatic cleaning
The SCS System® replaces conventional wet wells with a sloped collection chamber that continuously removes sediment and floating debris. Inline sump designs also avoid common problems associated with H2S smell and corrosion.
The ReliaSource® packaged stations integrate self-priming pumps with above-ground enclosures for safe, easy access and low maintenance.
Application areas
Industrial and Municipal Wastewater and Sewage
Self-cleaning and self-priming solutions prevent clogging and ensure continuous flow in municipal or industrial wastewater systems handling solids or fibrous material.
Where confined-space entry is undesirable or unsafe, Gorman-Rupp’s above-ground systems offer a safer, cleaner, and more cost-effective pumping solution.
How to select the right Gorman-Rupp solution
- Analyze the fluid – Determine solids size, concentration, and abrasiveness.
- Choose the configuration – Above-ground or submersible, depending on criteria such as space, maintenance and safety.
- Match performance – Align flow and head requirements with pump specifications.
- Ease of maintenance – Prioritize front-access designs that simplify servicing.
- Consider a full system – In many cases, a complete SCS or ReliaSource® package provides long-term efficiency gains.
Conclusion
For operations dealing with contaminated water or solids-laden liquids, Gorman-Rupp’s self-cleaning solutions combine reliability, ease of service, and lower lifecycle costs. With advanced self-priming technology and fully integrated system options, these pumps deliver dependable performance in even the most challenging environments.
Frequently Asked Questions About Self-Cleaning Pumps
What does “self-cleaning” mean for Gorman-Rupp?
It refers to pump and system designs that minimize solids buildup through automatic priming, free solids passage, and integrated self-flushing technologies.
Are all Gorman-Rupp pumps self-cleaning?
Not all models, but most self-priming lines and system packages, such as the SCS System® and ReliaSource®, include self-cleaning design options.
Can above-ground systems replace traditional wet wells?
Yes. The SCS System® uses a sloped collection design instead of a wet well, allowing automatic solids removal and safe above-ground maintenance.
How much maintenance can be saved?
While results depend on the application, Gorman-Rupp installations typically experience less downtime, reduced manual cleaning, and longer component life.
Are these systems suitable for fibrous or “stringy” materials?
Yes. Gorman-Rupp offers special configurations such as Eradicator® and Eradicator+™ options for handling stringy or fibrous solids efficiently.
What are the most common pump failure causes?
Proper suction line design, correct sizing, and accessible installation layout are essential for optimal performance and easy maintenance.
Can these pumps be used in temporary or mobile setups?
Absolutely. Self-priming, above-ground models are ideal for construction sites or temporary dewatering systems.
Where can I get technical support?
Through Gorman-Rupp Europe in Waardenburg, Netherlands and via the Gorman-Rupp Academy, which provides product training and sizing assistance. Or contact your local distributor for professional support.
