Product Description & Applications
The XWJ Non-Clogging Pulp Pump is a new-generation, energy-efficient pulp pump. Field applications have proven its high efficiency, minimal or zero leakage, excellent anti-clogging performance, smooth operation, high reliability, and compact structure. Its main features include: semi-open or fully-open impeller options, adjustable clearance between the wear plate and the front side of the impeller, mechanical seal as the primary sealing method, high-precision bearings (Grade D), and high-quality shaft materials.
The XWJ Non-Clogging Pulp Pump is widely used in light industry and papermaking for conveying pulp with a temperature below 110°C and a concentration below 6%. It can also be used in industrial and municipal water supply and drainage applications.
Structural Description
The XWJ Non-Clogging Pulp Pump is a single-stage, single-suction, cantilever-type structure, mainly composed of the pump body, impeller, pump cover, wear plate, and bearing bracket assembly.
Viewed from the motor end, the motor rotates clockwise. The pump features axial suction and radial (side) discharge.
The pump adopts a back-pull-out design, allowing maintenance without removing the inlet and outlet pipelines.
The pump shaft is supported by two high-precision rolling bearings and uses thin-oil lubrication (20# mechanical oil).
The shaft seal is available in two types: mechanical seal or packing seal.
The clearance between the wear plate and the impeller front side can be adjusted via an adjustment screw to maintain continuous high-efficiency impeller operation.
The pump and motor are directly connected via a pin-type coupling.
The wetted parts are available in HT200, QT450-10, ZG35, or ZG1Cr18Ni9Ti. The shaft materials are 40Cr or 3Cr13.
