Durrex Lobe Pumps and Processing Pumps in Pretoria

Acufill Processing and Packaging Equipment (Pty) Ltd supplies Durrex pump equipment to Pretoria businesses that require dependable product movement and in-line processing.

Rather than offering one standard solution for every application, the Durrex range includes several lobe pump, homogeneous pump and grinding pump designs. This makes it possible to select equipment according to viscosity, solids content, hygiene standards, operating pressure and available space.

Lobe Pumps for Controlled Flow

A lobe pump is a type of positive displacement rotary pump. It transfers product through the coordinated movement of two timed rotors inside the pump body.

As the lobes turn, product is drawn into the inlet and carried around the outside of the chamber towards the discharge. Internal clearances mean that the rotors do not rub against one another, reducing wear during operation.

This pumping method is suitable for both low- and high-viscosity media. Depending on the selected model, Durrex lobe pumps may process liquids, creams, pastes and mixtures containing particles.

Rotor designs are interchangeable within compatible pump models, allowing the pump to be adapted for different operating conditions.

Adjusting the Pump to the Process

Pretoria manufacturers may require different flow rates across products or batches. An inverter can be added to regulate pump speed and output.

Durrex also provides several installation options. Pumps may use flange, clamp or threaded connections, while adjustable bases can raise or lower the unit to match pipework.

Mobile pumps with trolley frames and control boxes are suitable where one unit must be used in multiple areas.

Solutions for Viscous and Heated Products

Products that are very thick may struggle to feed through a conventional round inlet. A rectangular inlet provides easier entry into the working chamber and can improve transfer of dense media.

Where product temperature must remain stable, a steam jacket can circulate hot water or steam around the pump. This reduces the chance of the medium cooling and solidifying during transfer.

For restricted production areas, a compact direct-connected pump design reduces the required installation space.

Hygienic Rotary Pump Options

Durrex offers lobe pumps for sanitary production conditions. Selected models support CIP and SIP and may be supplied with stainless-steel construction, hygienic connections and smooth product-contact surfaces.

Full guard covers protect drive components during cleaning. Built-in safety valves and mechanical seal lubrication options are also available on relevant designs.

Homogeneous Pump Technology

A homogeneous pump is used when ingredients must be mixed, refined, dispersed or emulsified during transfer.

Inside the chamber, rapidly rotating stators and rotors expose the product to intensive shearing and turbulent movement. Different DHX models provide different numbers of shearing stages, allowing the level of processing to be matched to the final product requirement.

Grinding Pump Equipment

Durrex grinding pumps are suitable for particle reduction and fine dispersion. Toothed-disc layers process the product through a sequence of decreasing gaps.

Manual models provide external handwheel adjustment, while automatic designs can integrate with local controls, PLC systems or a DCS.

Selecting a Durrex Pump in Pretoria

Acufill can assist Pretoria customers in choosing lobe pumps, a rotary pump, homogeneous pump equipment or a grinding pump. The selection is based on the medium, flow rate, temperature, pressure, cleanliness and installation requirements.
