FP-XA Flex-Coupled End Suction

The FP-XA flex-coupled end suction product line is one of the most economical fire production products available today.  This product can be electric or diesel engine driven and is available in many flows and pressures in both 50 & 60 cycle speeds.  The centerline discharge means that an air relief valve is not required, making this a more economical choice over other manufacturers tangential end suction designs.  Packing and grease lubrication round out the list of standard features that appear in our fire pump product line.  The performance is based off of our proven XA product line.
