What Do You Need To Pay Attention To When Choosing A Rotary Lobe Pump To Transport Sludge

lobe pumps are one of the more popular pieces of fluid equipment available. What matters need attention when choosing a lobe pump to transport sludge? Today Ace lobe pump's will tell you.

1、Solids content

A high solids content means high abrasiveness, so the corresponding lobe pump outlet speed needs to be reduced, if 3%, it is recommended to choose a speed of around 250 rpm.


If the sludge is industrial, then a stainless steel pump casing needs to be considered.

3. About particulate matter

Particles we need to pay attention to the texture as well as the particle size, the lobe pump cannot transport hard particles, while the particle size should be controlled at the mm level or even lower, if possible, add a basket filter at the front of the pump, or add a 50 mesh filter to the inlet line.

In addition, there is a point to note: for example, the pumping of river sludge, the use of lobe pumps to feed the stacker, solids content as well as viscosity uncertainty, at this time, the lobe pump outlet speed needs to be reduced, good choice of large diameter pump, equipped with frequency conversion motor, initially began to reduce the frequency of use, slowly return to 50HZ frequency, so as to ensure the stability of operation and reduce the consumption of wearing parts.
