The very first Hidrostal pump was developed in the 1960’s to transfer fresh fish from a trawler without causing damage to the stocks. From its successful origins in pumping fish, Hidrostal has diversified on to a wider range of applications that also benefit from the pumps delicate handling properties.
The F type pump from Hidrostal incorporating the unique single vane centrifugal impeller with a shroud are ideal for handling raw produce, offering more versatile piped transfer routes compared to conveyors, elevators or containers.
The enclosed pipework system has the benefit of being hygienic and cleaner as it is protected from any surrounding potential pollutants.
Operational costs are reduced with a pump piped system which is easier to maintain than belts or conveyors. Fewer exposed moving parts improve the Health & Safety environment.
In addition to the gentle handling requirements at the start of raw produce processing, the Hidrostal range is also suited to the energy efficient circulation and removal of the washwater used to clean raw produce. This often contains grit, sand, peelings and vegetable lumps. Hidrostal hydraulic parts built from hard materials and with a large free ball passage offer a robust and reliable solution.
The Hidrostal Screw Centrifugal Pump with closed impeller was specially developed for gentle handling of raw products at the beginning of food production. This includes delicate goods such as fruit and vegetables, which can be pumped in a carrier liquid to further manufacturing processes without damage or loss of quality.
The name is the program. Type "F" within the various product ranges of Hidrostal Screw Centrifugal Pumps actually means "Fish" and, with the closed pump impeller used here, is uniquely suitable for pumping live fish.
Just like slurries and liquids with a high solids content, the Hidrostal Screw Centrifugal Pump can also be used to pump pasty, highly viscous media without any problems. For these media, which are known to be difficult to transport, other feed systems often use the displacement device principle, which can have a negative influence on the condition with regard to the expected properties of the medium. Thanks to its outstanding properties in gentle handling, the Hidrostal pump enables uniformly continuous transport without changing the condition of the medium and thus meets the highest requirements even in extremely demanding and challenging production processes.
Huge quantities of slaughter by-products such as bones and gristle, fats and blood are supplied to the food and adhesives industry and further processed into the desired main or by-products in sometimes complex processes. Thanks to its unique suitability for gentle pumping of delicate and viscous media and its ability to pump liquids with a very high solids content without problems, the Hidrostal Screw Centrifugal Pump is suitable for a large number of applications in this market segment. The Hidrostal pump can be used for almost all individual production steps, from the raw material like bone meal to the media which often appear pasty and viscous in the further manufacturing processes.
