At a site in the North of England, where around 30,000 tonnes of carrots are processed each year across 900 acres of prime sandy land, the 11kW Landia units have, without any breakdowns or rebuilds, managed the important job of handling effluent from the carrot washing process that uses recirculated lagoon water.
The design of the world’s first ever Chopper Pump, invented by Landia in 1950, has changed very little in more than 75 years, with its external knife system continuously reducing particle sizes to prevent important wastewater systems from blocking.
Tamas Rieder, Landia’s Service and Aftersales Manager, commented: “We are very proud of the performance of these pumps and our service engineers who carry out such a consistently high level of work. Ten years of operation with no major problems is quite a record, but we have numerous pumps that are still working just fine after 15 and 20-years-plus service.
He added: “We work as closely as possible with our customers, gaining an increasing number of service contracts, but even if we don’t regularly carry out the maintenance ourselves, we are always ready to help at the end of ‘phone, and then get to site promptly, if required.”
In addition to this application for handling effluent from a carrot washing process, Landia’s large portfolio of similar projects also includes work with HAYLEY DEXIS at a company that makes machines for the post-harvest processing of vegetables.
Landia Chopper Pumps with special external shredders, replaced units from another manufacturer, whose equipment could not cope with the fibrous and gritty material that is an inevitable part of the wastewater process with vegetables.
Originally developed to deal with difficult wastewater solids in the fish processing industry, the Landia shredder-propeller design has now proved its capability in handling troublesome stringy material such as carrot tops, that typically cause problems for standard pumps.
Gary Wharton, Sales Team Leader for Landia, added:
“Our pre-cutting shredder-propeller brings another important chopping stage for certain effluents with difficult solids, as it continuously reduces particle size to keep process lines running efficiently.”
