Sludge pumping

Landia can offer durable pumping solutions for pumping all types of sludge.

Landia chopper pumps – also for sludge

Problem-free pumping of sludge is important for the proper operation of the sewage treatment plant. Often different types of displacement pumps are used for this task. They are capable of pumping highly viscous liquids such as sludge at high pressure but are often expensive to maintain and troublesome to service.

An excellent alternative is Landia’s chopper pump. The pump is simple, robust and easy to service. There are no fine tolerances that require adjustment after changing the impeller. This makes the pump much less sensitive to dry matter and sand, and it keeps the cost of operation and maintenance down.  As it is also a chopper pump, you are “insured” against blockages due to rags and other debris found in the sludge.

Are your current sludge pumps playing up?

Did you know that conservative displacement pumps can often be replaced with Landia’s centrifugal pumps? 
A displacement pump is often expensive to maintain and troublesome to service. A Landia pump is much less sensitive to abrasive particles, threads and other of the things that can be in sludge. And the day it still becomes necessary to change some parts, you will find that it is much simpler and faster compared to, for example, an eccentric screw pump.

The four chopper pumps have been very efficient since they were put into operation. The first three months they were really working hard. You could hear them chewing away on the tough media, where Landia’s unique knife system really did well.
