www.blackmer.com NP Series Fluid Processing and Transfer Sliding Vane Pumps SPEC SHEET 103-001 Section: 103 Effective: September 2007 Replaces: May 2005 Application Versatility The NP type positive displacement sliding vane pumps are specially designed to offer maximum versatility for handling a wide range of clean, non-corrosive fluids. Efficiency Means Energy Savings The high volumetric efficiency and symmetrical bearing support of the NP pumps means they require less horsepower than other PD pumps and up to 50% less power when handling viscous fluids. This means cost savings on both motors and electricity to operate the pumps. Self-Priming and Dry Run Capability The NP pumps are self-priming, and the self-adjusting vanes help maintain this capability. NP pumps can run dry for short periods of time for priming and line stripping. High Viscosity The NP pumps are ideal for handling viscous or shear sensitive fluids. The key to the NP series’ versatility is Blackmer’s unique sliding vane rotor design that provides sustained, high level performance over a wide viscosity range. Slow operating speeds and non-pulsating flow minimizes shear and agitation of the fluid. Optional Heating Jackets are available if required. NP2 with Steam Jackets How a Sliding Vane Pump Works
