Self-priming pumps and plate filters

Bruno Wolhfarth is specialized in the development of stainless steel self-priming electric pumps with flexible rubber impeller inside. Since it was established over 40 years ago, the company has developed machinery exclusively in stainless steel and it has always taken into consideration reliability and simple maintenance to ensure hygiene and duration.

The stainless steel Rapid series has been added to the Rapid Sanitary series while keeping in mind the particular demands of food, pharmaceutical and cosmetics sectors during both the planning and the execution. With respect to the standard version of the Rapid, Bruno Wolhfarth has eliminated all those parts which might cause product stagnation and be a source of contamination: the inside of the pump is a perfectly smooth single piece, obtained from a full bar with a turning and milling procedure; these characteristics allow perfect cleaning even with CIP washing. The impeller and gaskets are made of white silicone, a material certified as being suitable for use in contact with food, according to FDA regulations and in compliance with EEC 1935/2004 Regulation. In addition to stainless steel AISI 316L and upon request, the pump body can also be made of titanium, a metal that gives out less to the product and is also used in the medical-health-care field.

The electro-pumps are strongly self-priming, gently transport liquid and dense products and work in both directions. With low rpm motor or with speed variator, these pumps are suitable for transferring delicate products such as creams, emulsions, microspheres, or very thick products, such as pastes and ointments, and viscous products, such as honey, gel, glue for construction, resins, and paints. A filter with a stainless steel net inside, size 200, 400 or 800 µm, could be applied to the pump to filter impurities and corpuscles of the product, before the packaging.

In order to work in explosion-risk environments, these pumps can be supplied in Atex execution with ATEX II 2 GD c IIB TX certificate.

Bruno Wolhfarth is also specialized in the development of stainless steel plate filters. The Farminox and Labinox filters are used in food, pharm, cosmetic industries for filtering liquids, such as syrups, beverages, essential oils, and perfumes. They can work with filtering paperboards of different porosity in order to obtain the required degree of filtration. The most important characteristic of this filter is that it has no packing, as the patented round form provides a perfect sealing directly between the plate and the paper.

Smart lobe pumps

Omac introduces three new lobe pumps, the C110, C115 and C270 models. These pumps present a volumetric capacity of 0,17, 0,21 and 0,38 l/rev. respectively, for maximum pressure from 5 to 13 bars with increased clearances rotors.

C110 and C115 models are provided with DN40 connections, while the C270 model is provided with DN50 connections.

In order to achieve the highest hygienic standard, the lobe pumps are as easily fully cleanable as to enable hot water consumption and reduce the use of chemical products for their cleaning.

The materials used, surface finishing and all the characteristics of the design have enabled to get the European Hygienic Engineering & Design Group - EHEDG certification. Alike all other models Series C, the C100, C220 and C570 featured new design with new front loading seals for easier and quick servicing. In addition, maintenance is also simplified by means of a new external axial adjustment system.

All the parts in contact with the product are made of stainless steel 1.4404, pump body is cast with integral connections without welding. The rotors have been designed as to reach the best efficiency and cause less damage to the product at the same time.

The pumps of the Series C offer further energy saving, less power thanks to less internal friction and efficiency improvement thanks to the possibility of selecting three different tolerances of the rotors accordingly the working pressure. Two kinds of rotors are proposed, four-lobes and dual wing (bi-lobes) with new design.

The bearing housing is made of nickel-plated cast iron, sturdy and compact with roundish profile and equipped with feet for horizontal or vertical (self-draining) installation.

As the other Omac lobe pump series B and BF, appreciated all over the world for stoutness and performances, new C Series confirms their reliability and safety having obtained the Atex certification depositing technical file at TÜV. They can be supplied in Atex execution with classification II 2G kc T4, for the installation in areas with presence of atmosphere potentially explosive caused by gas/vapour and inflammable liquids.

All Omac lobe pumps are available also in special materials such as Titanium, Hastelloy, and Monel.
