vertical inline pump

The PACO VL/VLS series of Grundfos pumps are part of the SMART family of pump products which are better engineered to increase efficiency and reduce radial loads. SMART pumps are also designed to help reduce operating and maintenance costs.

The VL/VLS Inline pumps have proven to be extremely versatile, often exceeding the requirements for a variety of market applications, such as chilled water, condenser water, and hot water systems.


When floor space is a consideration, you’ll want to go with the VL. Where many other pumps might not fit, the VL’s vertical inline mounting guaran­tees the smallest footprint, literally requiring no floor space.


Grundfos pushes the limits of pump perfor­mance. The VL offers comprehensive sizes and configurations to meet your needs. It has a supe­rior hydraulic and mechanical design, which pro­duces higher efficiency, reduced pump noise, and longer pump life.

The VL can be fitted with a speed-control system, which significantly cuts energy use and provides a pump payback in as little as one to two years.

features & benefits
