The rotary lobe pump is a volumetric pump and the components can be made of different materials depending on the requirements of the working conditions.
The pump casing of the rotary lobe pump is available in ductile iron, carbon steel, stainless steel 304 and stainless steel 316.
The rotor of a rotary lobe pump can be selected from a rubber covered rotor, which is a special feature of rotary lobe pumps. Rubber covered rotors are available in a wide range of materials, such as.
Fluoroelastomer: suitable for media with PH 4.5-9, corrosive, mainly used in petroleum and petrochemicals, oily sewage, refined oil, lye, ammonium nitrate, concentrated sulphuric acid, etc.? and polyacrylamide in the municipal industry.
NBR: municipal wastewater, activated carbon, media with some abrasion
EPDM: methanol, ethanol
Hydrogenated NBR: abrasive, corrosive media
The material of the seal of the rotary lobe pump is selected according to the material of the rubber rotor. In general, the material of the inlet and outlet flange is the same as the material of the pump body.
Ace rotary lobe pumps are characterised by high pump efficiency, small footprint, online maintenance, forward and reverse rotation and simple dismantling. They are widely used in the fields of wear and tear resistance, corrosion resistance, mixed gas and liquid transfer and in sewage treatment where backwashing of filter membranes is required.
