Lobe Pumps for Manufacturing in KwaZulu-Natal

KwaZulu-Natal manufacturers operate across a broad range of industries, from food processing and chemicals to pharmaceuticals and general production. Acufill Processing and Packaging Equipment (Pty) Ltd supplies Durrex lobe pumps and related process pump technology for transferring and processing many different media.

The range includes rotary pump equipment for controlled movement, homogeneous pump systems for intensive mixing and grinding pumps for particle reduction. Each pump can be configured according to the medium, production conditions and required result.

Handling Viscous Products with Lobe Pumps

Durrex lobe pumps are particularly useful when a product is too thick, sticky or delicate for a conventional transfer method.

Two synchronised lobes rotate inside the chamber to carry product from the suction side to the discharge side. This positive displacement action provides a controlled transfer while internal clearances prevent direct contact between the rotors and housing.

The pump can handle products across a wide viscosity range. Depending on the rotor design, it may also transfer products containing soft solids or mixed gas, liquid and solid phases.

Different rotor profiles allow the equipment to be adapted for flow capacity, stability or gentler handling. Where the process requires variable output, an inverter can adjust the pump speed and flow rate.

Lobe Pump Options for Production Facilities

KwaZulu-Natal businesses can choose from several Durrex rotary pump configurations.

Steam-jacketed pumps help maintain product temperature by circulating steam or hot water around the pump chamber. This is useful where cooling could cause the medium to thicken or set.

Rectangular inlet pumps make it easier for high-viscosity materials to enter the chamber. Mobile trolley-mounted pumps provide flexibility where the equipment needs to move between storage vessels, mixing tanks or production lines.

Adjustable base plates assist with pipeline alignment, while short-body direct-connected designs can be selected where installation space is limited.

Hygienic Processing Requirements

For food, pharmaceutical and similar environments, Durrex offers hygienic lobe pumps designed to support regular cleaning and sanitation.

Selected pumps are suitable for CIP and SIP processes and can be supplied with clamp connections and stainless-steel protective covers. These covers help shield the motor and gearbox during cleaning activities.

Built-in hygienic safety valves are also available on selected pump designs to provide additional pump protection.

Homogeneous Pump Processing

A homogeneous pump applies high-speed shear to products that need to be mixed, dispersed, refined or emulsified.

As the product enters the working chamber, rotor and stator components expose it to repeated shearing, impact and turbulent flow. This helps break down agglomerates and combine materials that do not mix easily through basic agitation.

The DHX series offers different processing intensities through varying rotor, stator and shearing-stage arrangements.

Grinding Pump Applications

Durrex grinding pumps process products using several layers of toothed discs. The clearances become progressively narrower, allowing the material to move from coarse grinding to a finer final condition.

Manual models use a handwheel to adjust the gap, while automatic versions may be controlled locally or through PLC and DCS systems.
