Big Sludge Pump with big savings
In 2019, Lynetten ordered an Allweiler Optifix progressive cavity pump with Alldur stator from Copenhagen Pump. The Optifix pump with Alldur is Allweiler's answer to a competing technology to Mono Pump's Easy strip and Seepex long lasting SCT technology in one pump.
The market, especially in wastewater, has requested a pump technology where the pump can be disassembled and maintained with stator change, rotor change and shaft seal replacement easily and quickly, without the need to remove the pump from the piping system. Especially for large and heavy pumps, this advantage provides significant labor savings. At the same time, the operational savings are significant due to an extension of the service life of the rubber stator in particular.
Allweiler decided to develop a pump that could solve both challenges in one pump.
The Alldur concept was born in 2018 and is ingenious in that it is based on Allweiler's existing progressive cavity pump technology. Allweiler has chosen to make an assembly point on the drive shaft, which allows you to remove the stator and rotor in one piece in the installation. The entire operation can be completed in about 20 minutes. The lifetime aspect of the elastomer in the stator was solved a few years earlier with Alldur, a compound that lasts about 3 times longer than a traditional good rubber elastomer.
Overall, the operational savings with the new technology are 3-500%, according to Allweiler.
Allweiler's pricing strategy has been favorable for the buyer. The Optifix strategy costs about 10 percent more than a traditional pump. The Alldur technology is about 100% up on a normal Allweiler stator, but when buying a new pump, it can be traded marginally compared to a regular stator.
However, the big savings are subsequently seen in operation, where the customer basically operates their pump with common spare parts from the Allweiler program at regular low prices.
