ABSTRACT:
The invention relates to rotary vane type Positive Displacement Pumps having rotating slotted shaft in which is inserted single blade whose both ends touch the stationary shell assembly at all times because the blade's length substantially fits between the two intercepted interior surfaces of the shell assembly, thus maintaining separate suction (low pressure) and discharge (high pressure) regions always. The rotation of the shaft and the limited boundary imposed by the shell assembly actuate the blade to oscillate in the slot of the shaft while sweeping round the pumping chamber effecting continuous enlargement of the suction region and contraction of discharge region, with the end result of pumping liquid at constant flow per shaft rotation irrespective of head and pump power output.
