Grinding Pump with Manual-adjustable gap

The manually adjustable gap grinding pump is a high-performance homogenising pump that combines crushing, decomposition, depolymerisation, mixing, refining, homogenisation and emulsification.

Depending on the operating conditions and process requirements, the grinding pump can perform either coarse or fine grinding. The grinding gap is adjusted using an external handwheel, with an adjustment range of 0.2 mm to 8 mm.

Product Performance

The toothed disc can be fitted with a specialised grinding structure, with the clearance adjusted through the toothed disc.
A high-performance shearing toothed disc improves grinding efficiency.
The modular toothed disc can be interchanged between pumps of the same model, reducing operating and maintenance costs.
Adjusting the movable toothed disc simplifies maintenance and reduces maintenance difficulty.
A mechanical seal is used as the shaft seal, providing a longer service life.
The combined turbine and cam structure allows for easy operation and simple maintenance.
