High pressure pump solution for filter press cleaning
 With environmental legislation imposing even tighter restrictions on the treatment of industrial wastewater, effective filtration is increasingly being seen as an essential part of the overall treatment process. In order for filter presses to satisfy the purpose for which they are designed, that being to separate solids from liquid and form a filter cake, each filter cloth has to be capable of allowing the optimum level of filtrate to pass through during each operating cycle.
The creation of a high quality filter cake, in other words one that has a high solids and extremely low liquid content, is largely dependent on the effectiveness of the filter cloth. If the filtrate is unable to pass through the filter cloth, then the cake will retain more moisture than is desirable. This means that periodically the filter cloths within the press have to be thoroughly cleaned, for clean cloths result in a better quality filter cake and filtrate. In addition, regular cleaning will help to extend the operating life of the filter cloth.

Cat Pumps provide the pressure for food industry heat exchangers
 Scraped surface heat exchangers are widely used within the edible fats processing industry, but to provide the desired level of effectiveness the product being handled should be pumped at a constant pressure to achieve a constant liquid flow. This application is perfectly suited to triplex piston pumps manufactured by Cat Pumps.
The Chemetator scraped surface heat exchanger is regarded by many food manufacturers as the industry standard as it gives the product a consistent texture on a continuous system from blending to packaging. Capable of handing heat sensitive and viscous materials at temperatures from -35ºC to +170ºC, the Chemetator is perfectly suited to operations where batch processing methods or conventional heat exchangers would be regarded as inefficient.

Battery breaker uses Cat Pumps for screen washing.
Down in the depths of the Peak District resides the largest battery breaking and recycling plant in the UK. Operated by HJ Enthoven & Sons on the site of an historic lead mine, the Company recycles over 100,000 tonnes per year of industrial and automotive lead-acid batteries and is one of the most environmentally responsible and efficient plants for lead recycling in the world. Given the toxic nature of the batteries, the Company is very much aware of its environmental responsibilities and has invested considerable resources into ensuring that the local environment is not affected by its operations.

High pressure CO2 pumping in nuclear power stations
Liquid CO2 (carbon dioxide) is used in processes across many industries. However, pumping it presents an array of challenges both to equipment/systems manufacturers and plant managers because CO2 must be transferred at a controlled combination of low temperature and high pressure to minimise vapour forming. For the pump manufacturer, the inherent compressibility and poor lubricating properties also places special demands on pump design.

Triplex pumps for misting duties
Odour control within the landfill and waste treatment industries is largely achieved by the installation of a misting system, whereby a very fine spray of water is released into the atmosphere either adjacent to or above the affected area. Fine water droplets prevent the release of obnoxious odours to the wider environment. It is a proven technology and there are very many types of systems available on the world market.
