Selection of biogas slurry transfer pump
Thread Content
The existing pump for transferring slurry from the slurry tank is a submersible pump (with stirring function), but fiber entanglement in the sludge causes frequent clogging of this submersible pump. Since there is no separate pump pit on site, a cam rotor pump has been pre-installed as a temporary measure to maintain production. However, due to the current installation constraints, the inlet section of the rotor pump is located about 5–6 meters below the bottom of the slurry tank. Under such conditions (with a large suction height and viscous material), it is necessary to consider whether it is appropriate to install such a pump and what issues need to be taken into account.
The design institute advises you: With such a high suction lift, it is difficult even for a rotor pump to draw fluid up. Not to mention that the pump inlet is prone to clogging; even a slight blockage prevents it from sucking in anything at all. Unless the tank is sealed and can be pressurized with N2. It is still recommended to use a submersible pump for safety, with regular cleaning.
We can use our hose pump; it’s very suitable for this application.
You can choose our screw rotor pump. Features of the LZB spiral rotor pump: 1. It can transport media with a viscosity of
What conditions? A submersible pump with stirring function? Is there a reamer that isn’t suitable for long fibers? What’s the use of stirring? It’s used to prevent particulate matter from clogging things up.
Indeed, it’s better to use a cutting tool in this situation
It’s clear that the pump needs to have its reamer replaced; there’s no need to hesitate so much.
