The family of Constant Speed Vertical-In-Line Fire Pumps has been expanded with a maximum 500 USGPM flow for both 60hz and 50hz markets and featuring new high-pressure ratings of up to 160PSI. They eliminate the need for offset piping and motor realignment. They also use less floor space than comparable Horizontal Split Case designs.

#### Other features of this new model include: 

- Smaller motor than comparable pumps at the same duty point 
- Much smaller environmental footprint than standard diesel pumps 
- UL/ULC and FM approvals
