German Weinreich pump Weinreich model Weinreich price

Weinreich pumps are pumps in which the vanes in the rotor slots contact the pump casing (stator ring) to press the sucked liquid from the inlet side to the outlet side. There are two types depending on the classification: One) Specifically refers to vane pumps within positive displacement pumps. Two) Refers to the three dynamic pumps (centrifugal pumps, mixed-flow pumps, axial-flow pumps) or other special pumps. Such pump products are generally not called vane pumps. However, in monographs, vane pumps almost entirely refer to centrifugal pumps, mixed-flow pumps, axial-flow pumps, etc. Depending on whether the theoretical displacement per revolution is a fixed value or a variable value, they can be divided into variable displacement vane pumps and fixed displacement vane pumps.
