How Blackmer’s sliding vane action works

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.
