Inside mechanical seal structure. It reduces wear on the sliding surfaces and extends the seal's lifespan.
The "JM" is an inside mechanical seal type rotary pump. It achieves high discharge pressure through its "unique bearing structure" and "high rigidity shaft design." Regardless of back pressure fluctuations caused by "production capacity switching" or "downstream equipment switching," it provides high accuracy in dosing. Various special specifications can be accommodated, from mechanical seals and rotor shapes to O-rings, allowing it to handle liquids with various properties. 【Features】 ■ Sanitary specifications ■ Easy to disassemble and clean ■ Capable of transferring liquids from low to high viscosity ■ Transfers liquids without damaging solid components in the product ■ Maximum discharge pressure of 1.0 MPa (standard specification) *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 ■ Heat resistance temperature: 95℃ (standard specification), 150℃ (high temperature specification) ■ Capable of forward and reverse rotation ■ Can be used as a self-priming pump for extracting from a negative pressure tank ■ Quantitative performance ■ High versatility ■ Features of inside mechanical seal - Seals the fluid attempting to leak from the outer circumference to the inner circumference of the sliding surface - Since the leakage direction is opposite to the centrifugal force, it is less prone to leakage compared to outside mechanical seals and is suitable for harsh conditions such as high pressure and high-speed rotation. *For more details, please refer to the PDF document or feel free to contact us.
