Roto Series WM Progressing Cavity Pumps

Roto WM pumps are heavy duty pumps with wide throat inlets for applications involving solids to 15% such as Belt Filter Press.

Widethroat type inlet allows gravity flow of highly viscous (Plastico-viscous) material on to Augur-on-Coupling rod which pushes the substance to the pumping element. Available in Close Coupled and Bareshaft configurations.

Auger type suction inlet allows gravity flow of highly viscous (plastico-viscous) material on to Auger cum Coupling Rod which pushes the substance to the pumping element.

Pump construction in Mild Steel & Stainless Steel are standard with rotating parts of Alloysteel, Stainless Steel. In addition pumps can also be supplied in exotic materials like Alloy 20, Hastealloy, Super Duplex Steel etc. Torsion free Moulded to metal stator in Natural, Nitrile, Hi Nitrile, EPDM, Chlorosulfonated rubber, Fluro elastomer are standard. Shaft sealing by Gland packings/Mechanical seals.
