Self-Priming Storm & Sewage Pump Systems

In need of an upgrade to your existing submersible or collum style pumps? Metropolitan’s Self-Priming Pump provides a more efficient design that results in providing unique advantages over other pump types when it comes to the removal of storm and sewage water from indoor applications. The quick clean-out and back pull-out design of self-priming pumps are cleaner and provide easier access in mechanical applications as opposed to submersible pumps.

The Metro-Prime, our featured self-priming pump assembly, sits entirely on the basin cover eliminating the need to “pull” the pump from the wetwell for service. Any service or maintenance on the Metro-Prime is done entirely above the cover. It’s back pull-out design with only one moving part means that in most instances, the Metro-Prime can be serviced without ever disturbing the suction or discharge piping.

  • Clean, sanitary and dry
  • Easily accessible
  • Eliminates hoists
  • Serviceable by one person

Some of the advantages of our self-priming drainage pumps, as part of a Metropolitan designed and built packaged system include:

  • All equipment is above the cover
  • Quick clean out and easy maintenance
  • Low cost installation and repair
  • Close-coupled design and grooved suction elbow
  • Premium efficiency motors and impellers


Quick Clean-Out and Easy Maintenance:
Our self-priming drainage pump systems are shipped as complete packages, ready to set in place and bolt to the basin cover. Optional items such as electrical panels and suction pipes can be installed in minutes. Because our systems incorporate only one moving part, the integral shaft, and impeller, repair is seamless and inexpensive. Impellers, volute lip plates and suction wear rings can be replaced at low costs after wear occurs.

Close-Coupled Design and Grooved Suction Elbow: Our self-priming pumps incorporate a close-coupled design, allowing end users to remove its entire rotating assembly without disturbing piping. They are also engineered with a grooved suction elbow design, which provides further ease to the installation process.

Premium Efficiency Motors and Impellers: A hallmark of all of our commercial systems, our self-priming pumps are designed to provide efficient operation. These systems utilize a close-coupled, heavy duty, premium efficiency motor, and also apply fully enclosed impellers incorporating a solid bronze wear ring and a more efficient design.

Sophisticated Control Integration: For complete control of your self-priming drainage pump system, we recommend including one of Metropolitan’s custom-engineered controls panels. These panels include our exclusive Intellipump logic system and notification alarms if levels rise to unsafe limits.

If you’re tired of removing bulky submersible pumps for regular maintenance or repairs, Metropolitan’s self-priming pumps may provide an alternative option for your storm and sanitary sewage applications.

  • Conventional constant speed functionality for a majority of applications.
  • Optional variable speed functionality available for larger variable-flow storm-water applications, with minimal wet-well volume requirements.
  • Multiplex configurations (Duplex, Triplex, Quadraplex, Custom).
  • Pumps located above the wet-well allow safe access to the pumps for maintenance, eliminating the necessity of entering the wet-well.
  • Many pump models utilize impellers with well-established semi-open or enclosed design characteristics.
  • Totally-enclosed fan-cooled motors provided, to enhance the cooling-characteristics of the motor, while shielding the motor-windings from moist or harsh environments.
  • Advances in level-control technology as well as real-time two-way communication capabilities, provide options for virtually limitless human interaction and operational enhancements.
