When you need a flow rate of 8 m³/hr and the process liquid is a sealant with a viscosity of 500,000 cP, you need a pump that is a bit special. That’s just what we provided with our supply of a Viking Pump Q124A internal gear pump long coupled to an 11 kW 4 pole gear-motor. The Q124A is supplied in cast iron and typically has 4" ANSI flanges. When handling viscous liquids, it is important to minimise suction line pressure losses caused by viscous drag (friction) along the internal walls of the pipework. One way to do this is by increasing the pipework diameter, and in this example a 6” diameter line was utilised. Accordingly, the pump was supplied with a special 6" ANSI flange casing to accommodate the high liquid viscosity, ensuring a smooth, laminar flow into the pump. With a run speed of just 56 rpm, this unit will operate for many years without maintenance. Viking model Q124A complete with 56 RPM gearbox with 11 kW, 4 pole, 400 volt, 3 phase, 50 Hz IP55 motor mounted on baseplate via coupling and guard.
