MTR, SPK, MTH, and MTA pumps are vertical multi-stage centrifugal pumps used for pumping cooling and lubricating fluids required for mechanical processing equipment, as well as similar applications. This type of pump is installed at the top of the tank, and the pump riser is located in the liquid being pumped. Grundfos MTR, SPK, MTH, and MTA pumps offer a variety of products in different sizes and stages for users to choose from based on the required flow rate, pressure, and delivery length. This type of pump mainly consists of two components: the motor and the pump unit. The motor complies with EN standards and is a Grundfos standard MG motor. The pump unit consists of an optimized hydraulic system, various connection devices, a motor base, a fixed number of chambers, and other components.
