Bottrop, Germany -- Seepex, Inc. has a new cake pump that operates at higher volumetric efficiencies and has fewer wearing parts, compared to other PC pumps and piston pumps. The new Seepex BTH and BTHE pumps have a concentrically rotating auger that imparts substantially more shear to thixotropic sludge. This reduces the apparent viscosity and improves volumetric efficiencies.
Most PC pumps have an auger that is attached to a coupling rod that rotating in a conical movement, due to the eccentric action of the PC pump rotor on the discharge end of the auger.
The concentric auger in the seepex design is attached to a plate on the drive shaft and not the coupling rod. A in the suction hopper of the pump further stabilizes the auger. This design reduces wearing parts to a minimum, eliminates the extra shafts, gears and motors common to pumps with “bridge breakers” or twin-screw feeders.
The original designs of these pumps have been operating in California, now, without the need for replacement parts for over five years handling high solids centrifuge discharge.
Seepex GmbH + Co KG develops, manufactures and globally markets progressive cavity pumps for delivering low to highly-viscous, aggressive and abrasive media.
