Selection of vertical submersible pumps
Thread Content
Our factory produces wet phosphoric acid; after the concentration process, dilute phosphoric acid is turned into concentrated phosphoric acid with a concentration of around 47%. After the concentrated phosphoric acid is clarified, acid sludge must be removed. This acid sludge has a solid content of approximately 35% and a very high viscosity. At present, we are using pumps of the PLC65/350 type, with a flow rate of 50 m³, a head of 40 m, and a motor power of 30 Kw. The problems we are facing are high solid content, high motor temperature, a short service life for the pumps, and significant vibration. We hope everyone can help us figure out how to choose the right type of pump
Hello, our factory has pump models suitable for you – cantilever centrifugal submersible pumps. These pumps feature an open impeller and do not have submersible bearings; they are supported by two bearing sets above the water level, meaning two sets of rolling bearings. The pump shaft is thickened, making it a rigid shaft. It fundamentally solves the problems of bearing corrosion and wear beneath the liquid level in traditional submersible pumps, ensuring stable and reliable pump operation. The pump features a tangential outlet design that reduces wear; it is particularly suitable for media containing large amounts of solid particles as well as those that are highly corrosive and abrasive.
