Outside single mechanical seal. Due to the outer seal structure, the cleaning ability of the inside is improved.
The "JMU" is an outside single mechanical seal type rotary pump. Since the spring of the mechanical seal is located on the outside, the interior is designed to minimize liquid retention. Various special specifications are possible, from the mechanical seal and rotor shape to the O-ring. It can accommodate a wide range of transfer liquids with different properties. It is particularly suitable for liquids that "solidify when exposed to air," "contain slurries," and "are harmful if leaked externally." 【Features】 ■ Sanitary specifications ■ Easy to disassemble and clean ■ Capable of transferring liquids from low to high viscosity ■ Transfers liquids without breaking solid components ■ Maximum discharge pressure 1.0 MPa (standard specifications) *For more details, please refer to the PDF materials or feel free to contact us.
