Can Rotary Lobe Pumps Be Specially Customized?

lobe pumps can be specially tailored, including the drive unit, e.g. the way the motor is mounted, the direction of the inlet and outlet flanges, the distance, the material, etc.

The lobe pump has a top-mounted motor to reduce the use of space and is suitable for overall skid-mounted designs.

Especially for skid mounted pump sets designed for highland tunnels, highland motors can be used, the pump casing and flanges are made of wear resistant material and the rotor is fully covered with nitrile rubber, which is a special point for lobe pumps.

Depending on the requirements, the components of the lobe pump can be made of different materials.

The lobe pump casing is available in ductile iron, carbon steel, stainless steel 304 and stainless steel 316.

lobe pumps are available with rubber covered rotors, 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

In addition, the lobe pump has a self-priming capacity of 9m that other pumps do not have and does not need to be filled, making maintenance simple and eliminating the need to remove pipes and motors.
