Item Overview for Blackmer NP3F
The Blackmer NP3F is a 3" single-ended sliding vane pump finished in ductile iron construction. It also brings pre-engineered Integrated Unit Assemblies for drop-in installation. As part of the NP lineup, it shares parts and service procedures with the rest of the range. Capacity extends to 276 GPM, shortening load and unload cycles. Power reaches the pumping chamber through a single-ended keyed shaft turning right-hand, where Duravane vanes ride out against the liner to sustain flow as they wear. Containment comes from PTFE packing backed by FKM elastomers, a combination chosen for punishing liquids. NPT connections speed connection during commissioning and later service. Overpressure protection arrives built in, with an internal relief valve shielding the casing and downstream piping. Supplied as a bare unit, it drops into an existing drive arrangement or a purpose-built skid.
