VSHC Series — Variable Speed Horizontal Centrifugal Systems
Wastewater pump stations operate in demanding conditions — handling solids-laden fluid, operating continuously, and subject to strict regulatory requirements. PMC's VSHC (Variable Speed Horizontal Centrifugal) series is engineered specifically for these challenges, combining variable speed drive technology with horizontal centrifugal pump design for reliable, efficient wastewater handling.
The VSHC series is designed for flooded suction applications, where the pump inlet is below the fluid surface — eliminating priming requirements and improving reliability in high-cycle applications. Prefabricated building options are available for complete, weather-protected installations that arrive ready to connect.
PMC is also APG-Nueros certified for turbo blower startup and service — a critical credential for wastewater treatment facilities that use turbo blowers for aeration. Our certification ensures proper commissioning and ongoing service that meets manufacturer specifications.

Frequently Asked Questions
What is a variable speed horizontal centrifugal pump system?
A variable speed horizontal centrifugal (VSHC) pump system combines a horizontal centrifugal pump — where the impeller rotates on a horizontal axis — with a variable frequency drive (VFD) that adjusts motor speed to match actual flow demand. This combination delivers energy efficiency, reduced wear, and precise flow control. The horizontal configuration is well-suited for flooded suction applications common in wastewater treatment.
What is a flooded suction pump configuration?
In a flooded suction configuration, the pump inlet is positioned below the fluid surface in the wet well or sump. This means the pump is always primed — fluid flows to the pump by gravity rather than requiring the pump to create suction. Flooded suction is preferred for wastewater applications because it eliminates priming failures, reduces cavitation risk, and improves reliability in high-cycle duty applications.
What is APG-Nueros turbo blower certification?
APG-Nueros manufactures high-speed turbo blowers used for aeration in wastewater treatment. Their certification program ensures that service technicians are trained to properly start up and service these specialized blowers according to manufacturer specifications. PMC holds this certification, meaning we can perform warranty-valid startup and ongoing service for APG-Nueros turbo blowers at your facility.
Can PMC provide a complete prefabricated pump station building?
Yes. PMC offers prefabricated building options for wastewater pump stations — complete, weather-protected enclosures that house the pump, motor, control panel, and associated equipment. Prefabricated buildings arrive ready to set on a prepared pad and connect to your piping and electrical systems, reducing on-site construction time and ensuring a controlled-quality installation.
