Sliding vane pumps

Blackmer® has launched its NPH4F Sliding Vane Pump. The positive-displacement, sliding vane pump is designed to offer maximum versatility in fluid processing and transfer applications for a wide range of clean, non-corrosive fluids. The internal sleeve bearing pumps come standard with shaft packing and feature 180° ports, a distinction from the 90° ports of its NP4F predecessor. The new pump features ductile iron construction with an internal relief valve that protects against excessive pressures. The pumps are available with differential pressures up to 200 psi and maximum pump speeds of 500 rpm.
