Product details
The product page specifies suction pressure no higher than 0.2 MPa, maximum working pressure of 2.5 MPa, liquid temperature up to 100°C, density up to 1,600 kg/m³ and kinematic viscosity up to 30 cSt. These conditions require confirmation together for the selected materials and duty; they are not simultaneous guaranteed performance maxima.
The magnetic coupling drives the wetted rotor across a static containment boundary. The manufacturer describes stainless and special-alloy shaft options and several sliding-bearing materials, including graphite and silicon carbide choices. The exact combination must be selected for corrosion, lubrication and thermal conditions.
The stated liquid conditions exclude hard particles and fibres. The bearings depend on the pumped liquid for cooling and lubrication, so dry running is prohibited. Separate CQB-F fluoroplastic and CQB-G high-temperature families are not part of this rating. Confirm the selected duty curve, speed, motor loading and containment arrangement before ordering.
