Pumpsets Ltd can help with pump sizing for many applications. The pumps for this particular project had to be capable of handling sewage without blockage as well as having a low NPSH requirement due to the pumps drawing from a tank under vacuum. For an explanation of why NPSH is an important factor in selecting pumps please see the information shown below.
Pumpsets Ltd designed and built two self priming high flow, low head, low shear pumps with priming tanks for a shrimp farming application with all wetted parts constructed from 316 stainless steel. This method of pump priming enables higher efficiency pumps to be used which can be located above the water source removing the need for infrastructure to support and maintain alternative pumps types that require platforms or floating pontoons in order for their pump bowls to be submerged.
