Centrifugal –mag drive- pumps now pumping solids 3,2 mm

Centrifugal pumps, and especially mag drive centrifugal pumps, are not built to pump solids. The magnets will clog and will also be very easily damaged.

But, with this new balancing principle mag drive pumps can pump solids up to 3.2 mm

Why solids pumping is now possible with mag drive centrifugal pumps?

These series of centrifugal pumps have a single, enclosed impeller/magnet assembly. The assembly is free to rotate and slide on the central cantilevered shaft. The main flow of liquid/solids mixture enters the impeller and is pressurized and then expelled into the volute and out the discharge. A small portion of the flow passes behind the impeller. Through the back wear ring clearance than into the balance chamber. The back wear rings filter the solids from the fluid, resulting in a clean filtered liquid used for cooling and lubrication of the inner magnet, bearing and shaft.

This medium than flows through, past the bushings to exit at the valve. If the impeller moves forward, the valve is opened to a greater degree and the balance chamber pressure is reduced. This causes the impeller to react with a net force towards the motor. The valve is now closing and the balance chamber pressure increasing. This moves the impeller towards the suction. The net result is a very stable axial position for the impeller. There are no axial bearings and the radial bearings always operate in a pressurized fluid environment.

Features and benefits of the Verdermag mag drive solids pumping pump

• increased pump reliability and pump life because of balanced impeller
• Particles/solids cannot enter the containment shell of inner magnet gap
• SiC wear parts are standard at our mag drive pumps
• Wear rings function as secondary bearing to protect impeller and inner magnet assembly

Application areas

• metal plating
• chemical processing
• parts washing
• pharmaceuticals
• semi conductor
• food processing
