In the spring of 2021, Copenhagen Pump was contacted by a wastewater treatment plant regarding a replacement of older Allweiler pumps. Satisfaction with the existing pumps had been very high according to the plant and they therefore had a desire for a possible 1-1 replacement with a focus on modern shaft seals.
1-1 replacement
In consultation with the customer, we chose Allweiler's base model Optiflow with the code AEB 1 F 553. The pump matches the dimensions of several older models. In the design of Optiflow, emphasis has been placed on solid operating economy and favorable pricing, especially for wear parts.
Application:
The pumps are used to supply primary sludge to the decanter centrifuges.
Operation:
The pumps are designed for VFI operation. This has the advantage that you can easily control the supply of primary sludge to the centrifuges, possibly via a dry matter meter, which we can also supply together with the pump. During operation, the pumps wear out and the pump displacement is reduced. Over time, it is therefore necessary to compensate with increased speed input to maintain capacity. The pump is designed for about 200 rpm with the option to regulate up to an output speed of about 400 rpm.
