Performance

• Flow rates up to 96m3/h
• Pressures up to 15 bar

Features

• Shafts are made of heavy-duty, large-sectioned stainless steel for less deflection and enhanced rigidity
• Helical gears time the main and lay shafts to maintain accurate clearances between the rotors. These clearances ensure high volumetric efficiency and increased suction
• Main bearings are of the standard taper-roller type
• Gearboxes are grease or oil lubricated
• Shaft sealing can be achieved by mechanical seal, packed gland or “O” ring, to suit application
• The spigotted rotor case is positively located on the bearing housing, eliminating loose dowels
• The 12-involute spline configuration ensures accurate positioning of rotors during assembly
• Low-shear characteristics protect delicate products
• Positive displacement technology ensures efficient transfer of all liquid viscosities
• The pumping chamber is fully swept, ensuring no product entrapment
• “O” ring seal profiled to the edge of pumping chamber. Most covers are flush, minimising areas where bacterial growth can occur
• All wetted parts are made from 316 stainless steel
• Full diameter porting supplied as standard. Fittings available to suit customer specification. Enlarged inlets for hopper feed also available
• Shimming external to gearbox to allow for quick and simple adjustments of rotor clearances when required
• The gear housing is manufactured from robust cast iron
• Keyed gears produce a positive drive to ensure that timing does not have to be reset when rotors are changed
• “O” ring seals on rotor keeps splines free of product contamination
• The front cover can be supplied with a pressure relief valve built in to protect against overload.

Applications

• Food
• Pharmaceutical
• Dairy
• Hygiene-sensitive applications
• For pumping shear-sensitive or viscous fluids
