What model of pump should be chosen for the lift pump in the sludge thickening tank of the biochemical station? Our factory has chosen the 50WQ15-16-1.5 model, with inlet and outlet diameters of φ50mm, a flow rate of 15 m3/h, a head of 16m, and a motor power of 1.5 kw. The motor absorbs water continuously during use, resulting in high maintenance costs. I was wondering if any of the sea friends have any good pumps they can recommend.
Choose a shore pump, a self-priming pump
Press the water pump; it’s okay if it doesn’t self-priming. Install a buffer tank at the pump inlet

It is felt that the liquid density and viscosity in the sludge thickening tank are different from those in the regulating tank and collection wells. Our plant’s sump wells and regulating tanks have been equipped with self-priming pumps, which have proven to be effective; they not only facilitate maintenance but also reduce associated costs.
For the lift pump, use a vertical self-priming pump. . .

The self-priming pump is located on land, which eliminates the problem of motor damage caused by poor sealing; it is also easier to maintain and inspect. Unlike track pumps, which require several people working together to lift them up each time they need maintenance.
Self-priming sewage pumps are not suitable for the sludge in the sludge thickening tanks of biochemical treatment plants. We have conducted tests, and while their flow rate and head are two levels higher than those of submersible sewage pumps, their performance is still inferior to that of submersible sewage pumps.
