Mono Borehole range of Pumps offers reliable perfomance over a broad range of heads and speeds. These Pumps are able to operate under toughest conditions.

The stationery element of the Mono Pump known as Stator is moulded in nitrile rubber and incorporates a double internal helix with the transverse cross-section at any position along its length consisting of 2 parallel lines lines joined at each end by a semi-circle equal in diameter to the moving element.

The metal rotating element of a Mono pump known as the Rotor, is manufactured in the unique form of a single helix which at any point along its length is completely circular.When the Mono rotor is turned, its circular cross-section at any point along the length travels backwards and forwards across the stator section in one revolution. A slight interference fit on the single line of contact between the Rotor and the rubber Stator forms a complete seal in the axial direction along the full length of the 2 components. During normal operation, the line of contact which re-creates itself at the section end every revolution, moves continuously at uniform velocity, thus producing a non pulsating positive discharge. With 3 basic dimension of rotor Diameter, Pitch and Eccentricity, which can be combined in various permutations, the Mono pump is available to suit wide variety of needs.
