Grinding Pump (2)
The grinding pump is commonly referred to as a fine homogeniser. The main grinding unit features a double grinding-disc structure consisting of a rotor (moving toothed disc) and a stator (stationary toothed disc). Both the rotor and stator contain three layers made up of independent toothed discs. These multi-layer discs are arranged from a wider gap to a narrower gap and from coarse to fine, working from the inside out. This allows raw materials with different particle sizes to enter the pump chamber smoothly for gradual grinding, dispersion and homogenisation. The gap between the rotor and stator can be adjusted according to the particle size of the raw material or the specific process requirements. The grinding pump is available in three series: fixed, manually adjustable and automatically adjustable. -
Homogeneous Pumps (7)
The Homogeneous Emulsification Pump can be configured with one to three processing stages, incorporating two to six corresponding shearing stators and rotors. As the motor operates at high speed, the pump draws the medium into the working chamber. The stator and rotor components then process the material through mixing, dispersion, refining and emulsification -
Lobe Pumps (12)
Twin-rotary pumps are multifunctional, bidirectional positive displacement pumps. The pumps use synchronised rotors driven by a pair of timing gears within the gearbox. Power is transmitted through the main shaft and secondary shaft, causing the rotors to rotate synchronously in opposite directions. This pumping action creates a high vacuum and discharge pressure while allowing the pump capacity to vary according to operating conditions. Twin-rotary pumps are particularly suitable for transferring hygienic, highly corrosive and high-viscosity media.
