Grundfos SPK Tank-Mounted Pumps

Grundfos SPK Tank-Mounted Pumps for Machine Tools, Coolant Transfer, Cutting Oils, and Condensate Applications

Grundfos SPK Tank-Mounted Pumps are vertical multistage centrifugal pumps designed for mounting on top of tanks, with the pump stack immersed in the pumped liquid. The SPK range is commonly used for pumping cooling lubricants, cutting oils, condensate, and similar industrial liquids in machine tool systems, machining centers, filtration units, and industrial process applications.

The tank-mounted design makes Grundfos SPK pumps especially useful in machine tool environments where liquid must be drawn directly from a tank and delivered to a cutting, grinding, boring, washing, or filtration process. By keeping the motor and mounting arrangement above the tank while the hydraulic section operates in the liquid, SPK pumps help support compact system layouts and practical service access.

As a multistage pump, the SPK range can generate higher pressure than many simple single-stage tank transfer pumps. This makes it suitable for applications where cooling lubricant or cutting oil must be delivered at a controlled pressure to machine tools, process equipment, or condensate transfer points.

The SPK family includes multiple stage and connection configurations, allowing the pump to be selected according to tank depth, flow requirement, pressure requirement, motor size, and piping arrangement. This makes the SPK range a practical choice for industrial users who need dependable tank-mounted pumping in compact equipment packages, machining systems, and process liquid transfer applications.
